FIELD OF THE INVENTION 
     This invention concerns silver halide color photographic photosensitive materials which contain novel phenol type cyan dye forming couplers. 
     BACKGROUND OF THE INVENTION 
     Colored images are formed by the reaction of dye forming couplers (referred to hereinafter as &#34;couplers&#34;) with primary aromatic amine developing agents which have been oxidized by color development after the silver halide photographic photosensitive material has been imagewise exposed. In general, yellow, magenta and cyan colored images which have a complementary color relationship are used to reproduce blue, green and red colors using the subtractive method of color reproduction. Phenol derivatives or naphthol derivatives are often used as couplers for forming the cyan image. In color photography, the color forming couplers may be added to the developer or they may be incorporated in a photosensitive emulsion layer or another color image forming layer, and a non-diffusible dye is formed by reaction with the oxidized form of a color developing agent which is formed by development. 
     The reaction between the coupler and the color developing agent occurs at the active site of the coupler. Couplers which have a hydrogen atom at the active site are four equivalent couplers, which is to say, stoichiometrically, they require 4 mol of silver halide with development nuclei in order to form 1 mol of dye. On the other hand, couplers which have a group which can be eliminated as an anion at the active site are two equivalent couplers, which is to say these couplers only require stoichiometrically 2 mol of silver halide which has development nuclei to form 1 mol of dye. Thus, the amount of silver halide in the photosensitive material can generally be reduced and the film thickness can be reduced relative to that of a four equivalent coupler, the processing time for the photosensitive material can be shortened and the sharpness of the colored image which is formed is also improved. 
     Of these cyan couplers, the absorption of the dye which is formed using naphthol type couplers is at a sufficiently long wavelength and there is little overlap with the absorption of the magenta dye image. Moreover, since these couplers have a low to a high coupling activity with the oxidized form of a color developing agent they are widely used in photographic applications centered around color negative films. However, the dye images obtained from naphthol type couplers are reduced by ferrous ions which accumulate in fatigued bleach baths and bleach-fix baths and tend to fade (this is known as &#34;reduction fading&#34;) and the fastness of the image to heat is poor. As a result, there is a great demand for improvement. 
     On the other hand, phenol type cyan couplers which have a p-cyanophenylureido group in the 2-position and a carbonamido group which is a ballast group (a group which renders the molecule resistant to diffusion) in the 5-position are disclosed in U.S. Pat. No. 4,333,999. The dye formed using these couplers has a deep color shifted by association in the film and they provide colored images which have an excellent hue and provide excellent fastness. As a result, they are now being used widely as couplers to replace the above-described naphthol type cyan couplers. 
     However, although the dyes formed from phenol type couplers which have a ureido group in the 2-position provide a desirable hue in the high density areas, the peak absorption wavelength (λ max ) deviates to the short wavelength side in the low density areas and there is the disadvantage in that color reproduction is adversely affected. The combined use of 1-naphthol couplers with the above phenol type couplers is disclosed in JP-A-59-46644 and the combined use of a 5-amido-1-naphthol coupler with the above phenol type couplers is disclosed in JP-A-62-75444 as methods of overcoming this problem. (The term &#34;JP-A&#34; as used herein signifies an &#34;unexamined published Japanese patent application&#34;). 
     However, the demands for photographic photosensitive materials have become more severe recently and the demand for higher coupling reactivity and higher dye absorption densities have continued. 
     SUMMARY OF THE INVENTION 
     Hence, an object of the present invention is to provide silver halide color photosensitive materials which provide a high coupling reactivity and a high dye absorption density in which the dye formed has a preferred hue in both the low density regions and the high density regions. 
     As a result of thorough research to achieve the above-described objective, the inventors have discovered that the objective can be achieved by means of a silver halide color photosensitive material described below. 
     This is to say, the present invention provides a silver halide color photographic photosensitive material comprising a support having thereon a photographic layer which contains at least one silver halide emulsion layer wherein at least one cyan dye forming coupler represented by the formula (I) indicated below ##STR3## wherein R 1  represents a substituted or unsubstituted alkyl group, alkenyl group, alkynyl group, cycloalkyl group or aryl group, X 1  represents a single bond, --O--, --S--, --SO--, --SO 2  --, --COO--, ##STR4## R 2  represents a group which can be substituted on a benzene ring, L represents an integer of from 0 to 4, R 3  represents a substituted or unsubstituted aryl group and Z 1  represents a hydrogen atom or a coupling-off group and at least one cyan dye forming coupler represented by the formula (C) indicated below ##STR5## wherein R 1  represents --CONR 4  R 5 , --SO 2  NR 4  R 5 , --NHCOR 4 , --NHCOOR 6 , --NHSO 2  R 6 , --NHCONR 4  R 5 , or --NHSO 2  NR 4  R 5 , R 2  represents a group which can be substituted on a naphthalene ring, l represents an integer of from 0 to 3, R 3  represents a substituent group, and X 1  represents a hydrogen atom or a coupling-off group; R 4  and R 5  may be the same or different, each represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group, and R 6  represents an alkyl group, an aryl group or a heterocyclic group, when represents 2 or 3, the R 2  groups may be the same or different, or they may combine and form a ring; R 2  and R 3 , or R 3  and X 1 , may combine and form a ring; dimers or larger oligomers may be formed by joining together via divalent groups or groups of a valency greater than two in R 1 , R 2 , R 3  or X 1  are present in the photographic layer.

     SYNTHESIS EXAMPLE 
     Preparation of Coupler I-5 
     2-Hexyldodecanol (24.2 grams) and 7.9 grams of pyridine were dissolved in 100 ml of ethyl acetate and 14.8 grams of phthalic acid anhydride were added at room temperature (about 20°-30° C.) with stirring. After stirring the mixture for 3 hours at 50° C., the reaction mixture was transferred to a separation funnel, washed twice with dilute hydrochloric acid (1N) and concentrated. 
     The concentrate was dissolved in 50 ml of methylene chloride, 0.3 ml of N,N-dimethylformamide were added and 13 grams of oxalyl chloride were added dropwise over a period of about 30 minutes at room temperature with stirring. After stirring for about 1 hour, the mixture was concentrated and 2-dodecyloxycarbonylbenzoyl chloride was obtained in the form of an oil. 
     5-Amino-2-[3-cyanophenyl)ureido]phenol (24.2 grams) prepared using the synthesis method described in U.S. Pat. No. 4,333,999 was dissolved in 200 ml of dimethylacetamide and 2-dodecyloxycarbonylbenzoyl chloride was added dropwise over a period of about 30 minutes at room temperature with stirring. After the addition, the mixture was stirred for 2 hours and then the reaction mixture was transferred to a separation funnel. Ethyl acetate (500 ml) was added and the mixture was washed twice with dilute hydrochloric acid (1N) and then with a saturated aqueous sodium bicarbonate solution, after which it was dried over sodium sulfite. The ethyl acetate solution was concentrated to about half the original amount and the crystals which precipitated out were recovered by filtration. On drying, 36.9 grams of the target Coupler I-5 were obtained. The melting point of this compound was 185° C. to 189° C. and the structure was confirmed using  1  H NMR spectroscopy, mass spectrometry and elemental analysis.

     X 1  represents a hydrogen atom or a coupling-off group (known as a leaving group, including the atom which is eliminated, hereinafter the same), and typical of leaving groups include halogen atoms, --OR 11 , --SR 11 , ##STR69## thiocyanato groups, and heterocyclic groups which have a C number of from 1 to 30 which are bonded to the coupling active position through a nitrogen atom (for example, succinimido, phthalimido, pyrazolyl, hydantoinyl, 2-benzotriazolyl). Here, R 11  has the same significance as R 6  described above. 
     Examples of substituent groups preferred in formula (C) are indicated below. 
     For R 1 , --CONR 4  R 5  or --SO 2  NR 4  R 5  is preferred, and specific examples include carbamoyl, N-n-butylcarbamoyl, N-n-dodecylcarbamoyl, N-(3-n-dodecyloxypropyl)carbamoyl, N-cyclohexylcarbamoyl, N-[3-(2,4-di-tert-pentylphenoxy)propyl]carbamoyl, N-hexadecylcarbamoyl, N-[4-(2,4-di-tert-pentylphenoxy)butyl]carbamoyl, N-(3-dodecyloxy-2-methylpropyl)carbamoyl, N-[3-(4-tert-octylphenoxy)propyl]carbamoyl, N-hexadecyl-N-methylcarbamoyl, N-(3-dodecyloxypropyl)sulfamoyl and N-[4-(2,4-di-tert-pentylphenoxy)butyl]sulfamoyl. R 1  is most preferably --CONR 4  R 5 . 
     For R 2  and l, l=0, i.e., where there is no substituent, is most preferred, followed by l=1. R 2  is preferably a halogen atom, an alkyl group (for example, methyl, iso-propyl, tert-butyl, cyclopentyl), a carbonamido group (for example, acetamido, pivalamido, trifluoroacetamido, benzamido), a sulfonamido group (for example, methanesulfonamido, toluenesulfonamido) or a cyano group. 
     With R 3 , m is preferably 0 in formula (C-1), and more preferably R 7  is --COR 8  [for example, formyl, acetyl, trifluoroacetyl, 2-ethylhexanoyl, pivaloyl, benzoyl, pentafluorobenzoyl, 4-(2,4-di-tert-pentylphenoxy)butanoyl], --COOR 10  [for example, methoxycarbonyl, ethoxycarbonyl, iso-butoxycarbonyl, 2-ethylhexyloxycarbonyl, n-dodecyloxycarbonyl, 2-methoxyethoxycarbonyl] or --SO 2  R 10  [for example, methylsulfonyl, n-butylsulfonyl, n-hexadecylsulfonyl, phenylsulfonyl, p-tolylsulfonyl, p-chlorophenylsulfonyl trifluoromethylsulfonyl], and R 7  is most preferably --COOR 10 . 
     X 1  is preferably a hydrogen atom, a halogen atom, --OR 11  for example, alkoxy groups such as ethoxy, 2-hydroxyethoxy, 2-methoxyethoxy 2-(2-hydroxyethoxy)ethoxy, 2-methylsulfonylethoxy, ethoxycarbonylmethoxy, carboxymethoxy, 3-carboxypropoxy, N-(2-methoxyethyl)carbamoylmethoxy), 1-carboxytridecyloxy, 2-methanesulonamidoethoxy, 2-(carboxymethylthio)ethoxy, 2-(1-carboxytridecylthio)ethoxy and aryloxy groups such as 4-cyanophenoxy, 4-carboxyphenoxy, 4-methoxyphenoxy, 4-tert-octylphenoxy, 4-nitrophenoxy, 4-(3-carboxypropanamido)phenoxy, 4-acetamidophenoxy], or --SR 11  [for example, alkylthio groups such as carboxymethylthio, 2-carboxymethylthio, 2-methoxyethylthio, ethoxycarbonylmethylthio, 2,3-dihydroxypropylthio, 2-(N,N-dimethylamino)ethylthio and arylthio groups such as 4-carboxyphenylthio, 4-methoxyphenylthio, 4-(3-carboxypropanamido)phenylthio], and it is most preferably a hydrogen atom, a chlorine atom, an alkoxy group or an alkylthio group. 
     The couplers represented by formula (C) may form dimers or larger oligomers by bonding together via di- or higher valent groups as described for R 1 , R 2 , R 3  or X 1 . In this case, the above-described substituent groups may be outside the indicated carbon number range. 
     In those cases where a coupler represented by the formula (C) forms an oligomer, it is typically a homopolymer or copolymer of an addition polymerizable ethylenic unsaturated compound which has a cyan dye forming coupler residue group (cyan color forming monomer), and it is preferably represented by formula (C-2) 
     
         --(G.sub.i).sub.gi --(H.sub.j).sub.hj --                   (C-2) 
    
     In formula (C-2), G i  is a repeating unit derived from a color forming monomer, this being a group represented by formula (C-3), and H j  is a group which forms a repeating unit derived from a non-color forming monomer, i is a positive integer and j is 0 or a positive integer, and gi and hi indicate the proportions by weight of G i  and H j  respectively. When i or j is two or more, G i  or H i  can include a number of different types of repeating units. ##STR70## 
     In formula (C-3), R represents a hydrogen atom, an alkyl group which has from 1 to 4 carbon atoms or a chlorine atom, A represents --CONH--, --COO-- or a substituted or unsubstituted phenylene group, B represents a divalent group which has a carbon atom at both ends, such as a substituted or unsubstituted alkylene group, phenylene group, oxydialkylene group, and L represents --CONH--, --NHCONH--, --NHCOO--, --NHCO--, --OCONH--, --NH--, --COO--. --OCO--, --CO, --O--, --SO 2  --, NHSO 2  or --SO 2  NH--. Moreover, a, b and c represent integers of 0 or 1. Q represents a cyan coupler residue group in which one hydrogen atom has been removed from R 1 , R 2 , R 3  or X 1  of a compound represented by the formula (C). 
     The non-color forming ethylenic type monomer which does not couple with the oxidation product of a primary aromatic amine and- which provides the repeating unit H j  may be, for example, acrylic acid, α-chloroacrylic acid, α-alkylacrylic acid (for example, methacrylic acid), amides and esters derived from these acrylic acids (for example, acrylamide, methacrylamide, n-butylacrylamide, tert-butylacrylamide, diacetoneacrylamide, methyl acrylate, ethyl acrylate, n-propyl acrylate, n-butyl acrylate, tert-butyl acrylate, isobutyl acrylate, 2-ethylhexyl acrylate, n-octyl acrylate, lauryl acrylate, methyl methacrylate, ethyl methacrylate, n-butyl methacrylate and β-hydroxyethyl methacrylate), vinyl esters (for example, vinyl acetate, vinyl propionate and vinyl laurate), acrylonitrile, methacrylonitrile, aromatic vinyl compounds (for example, styrene and derivatives thereof, such as vinyl toluene, divinylbenzene, vinyl acetophenone and sulfostyrene), itaconic acid, citraconic acid, crotonic acid, vinylidene chloride, vinyl alkyl ether (for example, vinyl ethyl ether), maleic acid esters, N-vinyl-2-pyrrolidone, N-vinylpyridine and 2- and 4-vinylpyridine. 
     Acrylic acid esters, methacrylic acid esters and maleic aid esters are especially preferred. Two or more types of non-color forming ethylenic monomers can be used in combination. For example, methyl acrylate and butyl acrylate, butyl acrylate and styrene, butyl methacrylate and methacrylic acid or methyl acrylate and diacetoneacrylamide can be used in combination. 
     The ethylenically unsaturated monomer for copolymerization with the vinyl based monomer corresponding to the aforementioned formula (C-3) can be selected in such a way that the form of the copolymer which is obtained, for example whether it has a solid, liquid or micelle form and the physical and/or chemical properties, for example solubility (solubility in water or organic solvents), compatibility with binding agents such as gelatin, for example, which are used in photographic colloid compositions, flexibility, heat stability, coupling activity with the oxidized form of developing agents and fastness to diffusion in photographic colloids, are all favorably affected as is well known in the polymer coupler field. These copolymers may be random copolymers or copolymers which have a specified sequence (for example, block copolymers, alternating copolymers). 
     The number average molecular weight of the cyan polymer couplers which can be used in the present invention is generally from a few thousand to a few million, and oligomeric polymer couplers of number average molecular weight less than 5000 can also be used. 
     The cyan polymer couplers used in the present invention may be lipophilic polymers which are soluble in organic solvents (for example, ethyl acetate, butyl acetate, ethanol, methylene chloride, cyclohexanone, dibutyl phthalate, tricresyl phosphate) or hydrophilic polymers which can be mixed with hydrophilic colloids such as aqueous gelatin solutions, or they may be polymers which have a structure and nature which form micelles in hydrophilic colloids. 
     The selection of lipophilic non-color forming ethylenic monomers (for example, acrylic acid esters, methacrylic acid esters, maleic acid esters, vinylbenzenes) for the main copolymer component is preferred for obtaining lipophilic polymer couplers which are soluble in organic solvents. 
     A lipophilic polymer coupler obtained by polymerizing a vinyl monomer which provides coupler units represented by the aforementioned formula (C-3) can be dissolved in an organic solvent and emulsified and dispersed in the form of a latex in an aqueous gelatin solution, or it can be prepared using a direct emulsion polymerization method. 
     The method for the emulsification and dispersion of lipophilic polymer couplers in aqueous gelatin solutions in the form of a latex disclosed in U.S. Pat. No. 3,451,820 can be used, and the methods disclosed in U.S. Pat. Nos. 4,080,211 and 3,370,952 can be used for emulsion polymerization. 
     Furthermore, the use of hydrophilic non-color forming ethylenic monomers such as N-(1,1-dimethyl-2-sulfonatoethyl)-acrylamide, 3-sulfonatopropyl acrylate, sodium styrenesulfonate, potassium styrenesulfinate, acrylamide, methacrylamide, acrylic acid, methacrylic acid, N-vinylpyrrolidone, and N-vinylpyridine for example as copolymer components is preferred for obtaining hydrophilic polymer couplers which are soluble in neutral or alkaline solution. 
     Hydrophilic polymer couplers can be added as aqueous solutions to a coating liquid, and they can also be dissolved in mixed solvents comprising water and an organic solvent which is miscible with water such as a lower alcohol, tetrahydrofuran, acetone, ethyl acetate, cyclohexanone, ethyl lactate, dimethylformamide or dimethylacetamide for addition. Moreover, they can be dissolved in aqueous alkali solutions or in alkaline water containing organic solvents for addition. Furthermore, a small amount of surfactant can be added, if desired.

     The cyan couplers of the present invention can be introduced into the photosensitive material using the oil in water dispersion method. High boiling point organic solvents can be used in a ratio by weight with respect to the coupler of from 2.0 to zero. The ratio by weight of high boiling point organic solvent used is preferably from 1.0 to zero, and in comparison to other cyan couplers which have a similar structure the couplers of the present invention can be dispersed in a stable manner using a small amount of high boiling point organic solvent ranging from 1.0 to zero in terms of the ratio by weight. The fact that stable dispersions are obtained without using a high boiling point organic solvent is a distinguishing feature of the color photographic photosensitive materials of this present invention. 
     Coupler solvents described hereinafter can be used as coupler solvents in the present invention, if desired, but for cyan couplers the use, for example, of high boiling point organic solvents such as phthalic acid esters (for example, dibutyl phthalate, di-2-ethylhexyl phthalate, didodecyl phthalate, ethylphthalylethylglycolate), fatty acid esters (for example 2-ethylhexyl tetradecanoate, di-2-ethylhexyl adipate, di-2-ethylhexylsebacate, 2-ethylhexyl 9,10-epoxystearate), benzoic acid esters (for example 2-ethylhexyl benzoate, dodecylbenzoate, hexadecyl 4-hydroxybenzoate), phenols (for example, 2,4-di-tert-penthylphenol, 2,4-dinonylphenol, 2,4-didoecylphenol) and chlorinated paraffins (for example, paraffins with a 40 to 70 wt. % chlorine content) is preferred. 
     The cyan couplers of the present invention can be used in any photosensitive emulsion layer, nonphotosensitive emulsion layer or intermediate layer, but they are preferably added to and used in a photosensitive emulsion layer, and most desirably they are added to and used in the red sensitive silver halide emulsion layer. 
     The cyan couplers of the present invention may be used independently as cyan couplers or they can be used in combination with other cyan couplers, if desired. Preferred cyan couplers which can be used in combination with the cyan couplers of the present invention include 1-naphthol type cyan couplers, 5-amido-1-naphthol type cyan couplers (disclosed in U.S. Pat. No. 690,899 (sic) and JP-A-64-78252) and 2-ureidophenol type cyan couplers (disclosed in JP-A-64-2044). The amount of the other cyan couplers which can be used in combination with the cyan couplers of the present invention is preferably less than 50 wt. % based on the total amount of the cyan couplers. 
     The couplers of the present invention can be used, for example, in color papers, color reversal papers, color positive films, color negative films, color reversal films and color direct positive photosensitive materials. Their use in color negative films is especially preferred. 
     The silver halide emulsion of a photosensitive material as used in the present invention may have any halogen composition. For example, a silver iodobromide, silver bromide, silver chlorobromide or silver chloride emulsion may be used. 
     The halogen composition of the emulsion may be the same or different from grain to grain, but uniformity in the grains is facilitated when emulsions in which the halogen composition is uniform from grain to grain are used. Furthermore, the grains of the silver halide emulsion can comprise grains which have a so-called uniform type structure in which the composition is the same in all parts of the grains of the silver halide emulsion, grains which have a so-called layer type structure in which the silver halide composition is different in the interior core of the silver halide grains from that in the shell (which may be a single layer or a plurality of layers) which surrounds the core, or grains which have a part which has a different halogen composition in a non-layer-like form either within the grains or on the grain surface (in the case of the grain surface, the structure is such that the part which has a different composition is present on the edges, the corners or on the surfaces of the grain). These can be selected appropriately and used. The use of either of the latter two types of grains rather than grains which have a uniform structure enables high photographic speeds to be obtained, and these grains are also preferred from the standpoint of pressure resistance. Where the silver halide grains have a structure such as that described above, the boundary surface between the parts in which the halogen composition differs may be a distinct boundary, or mixed crystals may be formed with a composition difference and the boundary may be indistinct, or there may be a positive and continuous change in the structure. 
     The halogen composition differs depending on the type of photosensitive material being used. With print materials such as color papers, for example, silver chlorobromide emulsions are mainly used, while with camera materials such as color negative films, silver iodobromide emulsion are generally used. 
     Furthermore, the so-called high silver chloride emulsions which have a high silver chloride content are preferably used in photosensitive materials which are suitable for rapid processing. The silver chloride content of these high silver chloride emulsions is preferably at least 90 mol %, and most preferably at least 95 mol %. 
     Structures which have a layer-like or non-layer-like silver bromide localized phase either within the silver halide grains and/or at the grain surface as described earlier are preferred for such high silver chloride emulsions. The silver halide composition of the above described localized phase is preferably such that the silver bromide content is at least 10 mol %, and preferably in excess of 20 mol %. Hence, these localized layers can be present within the grains or on the edges or corners of the grain surfaces or on the surfaces of the grains, and in one preferred example, the localized phase is grown epitaxially on the corners of the grains. 
     The average grain size (the grain diameter in the case of grains which are spherical or approximately spherical, or, in the case of a cubic grain the edge length is taken for the grain size, the average being based on the projected area) is preferably not more than 2 μm but at least 0.1 μm, and most preferably not more than 1.5 μm but at least 0.15 μm. The grain size distribution may be narrow or wide, but the use of the so-called mono-disperse silver halide emulsions in which the value (coefficient of variation) obtained by dividing the standard deviation of the grain size distribution of the silver halide emulsion by the average grain size is within 20%, and preferably within 15%, is desirable in the present invention. Furthermore, two or more mono-disperse silver halide emulsions (preferably with a coefficient of variation as described above) which have different grain sizes can be employed in the same layer or lamination coated as separate layers for an emulsion layer unit which has essentially the same color sensitivity. Moreover, mixtures comprising laminations of or combinations of two or more types of poly-disperse silver halide emulsions or of mono-disperse and poly-disperse emulsions can also be used, if desired. 
     The crystalline form of the silver halide grains used in the present invention may be regular form, such as a cubic, octahedral, rhombo-dodecahedral or tetradecahedral form, or a combination of these regular forms. Alternatively, they may have an irregular crystalline form such as a spherical form, or they may have a form which is a composite of such forms. Furthermore, tabular grains may be used. 
     The silver halide photographic emulsions which can be used in the present invention can be prepared, for example, using the methods disclosed in Research Disclosure (RD) No. 17643 (December, 1978), pages 22 to 23, &#34;I. Emulsion Preparation and Types&#34;, and ibid, No. 18716 (November 1979), page 648, in P. Glafkides, Chimie et Physique Photographique, published by Paul Montel, 1967, in G. F. Duffin, Photographic Emulsion Chemistry, published by Focal Press, 1966, and in V. L. Zelikmann et al., Making and Coating Photographic Emulsions, published by Focal Press, 1964. 
     The mono-dispersed emulsions disclosed, for example, in U.S. Pat. Nos. 3,574,628 and 3,655,394, and British Patent 1,413,748 are preferred. 
     Furthermore, tabular grains where the aspect ratio is at least about 5 can be used in the present invention. Tabular grains can be prepared easily using the methods described, for example, in Gutoff, Photographic Science and Engineering, Volume 14, pages 248 to 257 (1970), and in U.S. Pat. Nos. 4,434,226, 4,414,310, 4,433,048 and 4,439,520, and British Patent 2,112,157. 
     The crystal structure may be uniform, or the interior and exterior of the grains may have different halogen compositions, or the grains may have a layered structure and, moreover, silver halides which have different compositions may be joined with an epitaxial junction or they may be joined with compounds other than silver halides, such as silver thiocyanate or lead oxide, for example. 
     Mixtures of grains which have various crystalline forms may be used. 
     The silver halide emulsions which are used have generally been subjected to physical ripening, chemical ripening and spectral sensitization. Additives which are used for such purposes are disclosed in Research Disclosure Nos. 17643 and 18716, and these disclosures are summarized in the table below. Known photographically useful additives which can be used in this present invention are also disclosed in the two Research Disclosure references referred to above, and these disclosures are also indicated in the table below.

These compounds can be added to the photosensitive layer after co-emulsification with the corresponding color coupler, generally in an amount of from 5 to 100 wt. % with respect to the coupler. The inclusion of ultraviolet absorbers in the cyan color forming layer and in the layers on both sides adjacent thereto is effective for preventing deterioration of the cyan dye image due to heat and, more especially, due to light.

     Color development is carried out after a normal black and white development in cases where reversal processing is carried out. Known black and white developing agents, for example, dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone or aminophenols such as N-methyl-p-aminophenol can be used individually, or in combination, in the black and white developer. 
     The pH of these color developers and black and white developers is generally within the range of 9 to 12. The replenishment rate of these developers depends on the color photographic material which is being processed, but it is generally 3 liters or less per square meter of the color photographic material, and it can be below 500 ml per square meter of the photographic material by reducing the bromide ion concentration in the replenisher. Prevention of evaporation and aerial oxidation of the liquid by reducing the area of contact with air in the processing tank is desirable in those cases where the replenishment rate is reduced. Furthermore, the replenishment rate can be further reduced by adopting means of suppressing the accumulation of bromide ion in the development bath. 
     The photographic material is generally subjected to a bleaching process after color development. The bleaching process may be carried out at the same time as the fixing process (in a bleach-fix process) or it may be carried out as a separate process. Moreover, a bleach-fix process can be carried out after a bleaching process in order to speed up the processing. Moreover, a bleach-fixing process can be carried out in two connected bleach-fix baths, a fixing process can be carried out before a bleach-fixing process or a bleaching process can be carried out after a bleach-fix process depending on the intended purposes. 
     Compounds of multi-valent metals, such as iron(III), cobalt(III), chromium(VI) and copper(II), peracids, quinones and nitro compounds, for example, can be used as bleaching agents. Typical bleaching agents include ferricyanides; dichromates; organic complex salts of iron(III) or cobalt(III), for example, complex salts with aminopolycarboxylic acids such as ethylenediamine tetraacetic acid, diethylenetriamine pentaacetic acid, cyclohexanediamine tetraacetic acid, methylimino diacetic acid, 1,3-diaminopropane tetraacetic acid and glycol ether diamine tetraacetic acid, or citric acid, tartaric acid or malic acid; persulfates; bromates; permanganates; and nitrobenzenes. Of these materials, polyaminocarboxylic acid iron(III) complex salts, principally ethylenediamine tetraacetic acid iron(III) complex salts, and persulfates, are preferred from the standpoints of both rapid processing and prevention of environmental pollution. Moreover, aminopolycarboxylic acid iron(III) complex salts are especially useful in both bleach baths and bleach-fix baths. The pH of the bleach baths and bleach-fix baths in which these aminopolycarboxylic acid iron(III) salts are used is normally from 5.5 to 8, but lower pH&#39;s can be used in order to speed up processing, if desired. 
     Bleaching accelerators can be used, as required, in the bleach baths, bleach-fix baths or bleach or bleach-fix pre-baths. Specific examples of useful bleach accelerators include compounds which have a mercapto group or a disulfide bond disclosed, for example, in U.S. Pat. No. 3,893,858, West German Patent 1,290,812, JP-A-53-95630 and Research Disclosure No. 17129 (June 1978); the thiazolidine derivatives disclosed in JP-A-50-140129; the thiourea derivatives disclosed in U.S. Pat. No. 3,706,561, the iodides disclosed in JP-A-58-16235; the polyoxyethylene compounds disclosed in West German Patent 2,748,430; the polyamine compounds disclosed in JP-B-45-8836; and bromide ion. Of these compounds, those which have a mercapto group or a disulfide group are preferred in view of their large accelerating effect, and the compounds disclosed in U.S. Pat. No. 3,893,858, West German Patent 1,290,812 and JP-A-53-95630 are especially preferred. Moreover, the compounds disclosed in U.S. Pat. No. 4,552,834 are also preferred. These bleach accelerators may also be added to a light sensitive material, if desired. These bleach accelerators are especially effective when bleach-fixing color photosensitive materials for camera use. 
     Thiosulfate, thiocyanate, thioether based compounds, thioureas and large amounts of iodide can be used, for example, as fixing agents, but thiosulfate is normally used, and ammonium thiosulfate in particular can be used in the widest range of applications. Sulfites, bisulfites or carbonyl bisulfite addition compounds are preferred as preservatives for bleach-fix baths. 
     The silver halide color photographic materials of the present invention are usually subjected to a water washing process and/or stabilization process after the de-silvering process. The amount of wash water used in the washing process can be fixed within a wide range, depending on the application and the nature (for example the materials such as couplers which have been used) of the photosensitive materials, the wash water temperature, the number of water washing tanks (the number of water washing stages) and the replenishment system, i.e. whether a counter flow or a sequential flow system is used, and other conditions. The relationship between the amount of water used and the number of washing tanks in a multi-stage counter-flow system can be obtained using the method described on pages 248 to 253 of the Journal of the Society of Motion Picture and Television Engineers, Volume 64 (May 1955). 
     The amount of wash water can be greatly reduced by using the multi-stage counter-flow system described above, but bacteria proliferate due to the increased residence time of the water in the tanks. Thus, problems arise with suspended matter which is produced and which attaches to the photosensitive material. The method in which the calcium ion and magnesium ion concentrations are reduced, as disclosed in JP-A-62-88838, is very effective as a means of overcoming this problem when processing color photosensitive materials of the present invention. Furthermore, the isothiazolone compounds and thiabendazoles disclosed in JP-A-57-8542, the chlorine based disinfectants such as chlorinated sodium isocyanurate, and benzotriazole, for example, and the disinfectants disclosed in Horiguchi, The Chemistry of Biocides and Fungicides, published by Sankyo Shuppan, 1986, in Killing Micro-organisms, Biocidal and Fungicidal Techniques, published by the Industrial Technology Association, 1982, and in A Dictionary of Biocides and Fungicides, edited by the Japanese Biocide and Fungicide Society publication (1986) can also be used in this connection. 
     The pH of the water wash water when processing photosensitive materials of the present invention is from 4 to 9, and preferably from 5 to 8. The washing water temperature and the washing time can be varied depending on the nature and application of the photosensitive materials but, in general, washing conditions of from 20 seconds to 10 minutes at a temperature of from 15° C. to 45° C., and preferably of from 30 seconds to 5 minutes at a temperature of from 25° C. to 40° C., are used. Moreover, the photosensitive materials of this invention can be processed directly in a stabilizing bath instead of being subjected to a water wash as described above. Known methods disclosed in JP-A-57-8543, JP-A-58-14834 and JP-A-60-220345 can be used in such a stabilizing process. 
     Furthermore, in some cases a stabilization process is carried out following the above-described water washing process, and stabilizing baths which contain formaldehyde and a surfactant which are used as final baths for camera color photosensitive materials are an example of such a process. Various chelating agents and fungicides can also be added to these stabilizing baths, if desired. 
     The overflow which accompanies replenishment of the above mentioned water washing or stabilizing baths can be reused in other processes, such as the desilvering process, for example. 
     Color developing agents can be incorporated into the silver halide color photosensitive material of the present invention to simplify and speed up processing. The incorporation of various color developing agent precursors is preferred. For example, the indoaniline based compounds disclosed in U.S. Pat. No. 3,342,597, the Shiff&#39;s base type compounds disclosed in U.S. Pat. No. 3,342,599 and Research Disclosure No. 14850 and ibid, No. 15159, the aldol compounds disclosed in Research Disclosure No. 13924, the metal complex salts disclosed in U.S. Pat. No. 3,719,492 and the urethane based compounds disclosed in JP-A-53-135628 can be used for this purpose. 
     Various 1-phenyl-3-pyrazolidones can also be incorporated, as desired, into the silver halide color photosensitive materials of the present invention to accelerate color development. Typical compounds of this type have been disclosed, for example, in JP-A-56-64339, JP-A-57-144547 and JP-A-58-115438. 
     The processing baths used in this invention are conducted at a temperature of from 10° C. to 50° C. A standard temperature is generally from 33° C. to 38° C., but accelerated processing and shorter processing times can be achieved at higher temperatures while, on the other hand, improved picture quality and better processing bath stability can be achieved at lower temperatures. Furthermore, processes using hydrogen peroxide intensification or cobalt intensification as disclosed in West German Patent 2,226,770 or U.S. Pat. No. 3,674,499 can be used in order to economize on silver in the photosensitive material. 
     The present invention is described in greater detail below by means of illustrative examples, but the present invention is not to be construed as being limited by these examples. Unless otherwise indicated herein, all parts, percents, ratios and the like are by weight.

     The gamma value (the gradient from density 1.0 to density 2.0) and D max  (the maximum color density) of the cyan colored samples (Samples 101 to 116) Obtained in the color development process were measured. Furthermore, the peak absorption wavelength was measured at color densities of 0.5 and 2.0 and Δλ max  was obtained using the following equation: 
     
         Δλ.sub.max =Peak Absorption Wavelength at Color Density 2.0 -Peak Absorption Wavelength at Color Density 0.5

     It is clear from the results in Table 1 above that when a photosensitive material of the present invention is used, the coupling reactivity is higher than with the comparative coupler examples, and images which have a high maximum color density are obtained. Furthermore, the difference in the hue between areas of high and low density is satisfactorily small and this is desirable.
