     FIELD OF THE INVENTION 
     This invention relates to an ink jet printing process for improving the Dmax density and light stability of an ink jet printed image containing a water-soluble dye. 
     BACKGROUND OF THE INVENTION 
     Ink jet printing is a non-impact method for producing images by the deposition of ink droplets in a pixel-by-pixel manner to an image-recording element in response to digital signals. There are various methods that may be utilized to control the deposition of ink droplets on the image-recording element to yield the desired image. In one process, known as continuous ink jet, a continuous stream of droplets is charged and deflected in an imagewise manner onto the surface of the image-recording element, while unimaged droplets are caught and returned to an ink sump. In another process, known as drop-on-demand ink jet, individual ink droplets are projected as needed onto the image-recording element to form the desired image. Common methods of controlling the projection of ink droplets in drop-on-demand printing include piezoelectric transducers and thermal bubble formation. Ink jet printers have found broad applications across markets ranging from industrial labeling to short run printing to desktop document and pictorial imaging. 
     The inks used in the various ink jet printers can be classified as either dye-based or pigment-based. A dye is a colorant that is molecularly dispersed or solvated by a carrier medium. The carrier medium can be a liquid or a solid at room temperature. A commonly used carrier medium is water or a mixture of water and organic co-solvents. Each individual dye molecule is surrounded by molecules of the carrier medium. In dye-based inks, no particles are observable under the microscope. Although there have been many recent advances in the art of dye-based ink jet inks, such inks still suffer from deficiencies such as low optical densities on plain paper and poor light-fastness. When water is used as the carrier medium, such inks also generally suffer from poor water-fastness. 
     An ink jet recording element typically comprises a support having on at least one surface thereof an ink-receiving or image-forming layer. The ink-receiving layer may be a polymer layer that swells to absorb the ink or a porous layer that imbibes the ink via capillary action. 
     Ink jet prints, prepared by printing onto ink jet recording elements, are subject to environmental degradation. They are especially vulnerable to water smearing, dye bleeding, coalescence and light fade. For example, since ink jet dyes are water-soluble, they can migrate from their location in the image layer when water comes in contact with the receiver after imaging. Highly swellable hydrophilic layers can take an undesirably long time to dry, slowing printing speed, and will dissolve when left in contact with water, destroying printed images. Porous layers speed the absorption of the ink vehicle, but often suffer from insufficient gloss and severe light fade or fade induced by atmospheric ozone. 
     U.S. Pat. No. 4,926,190 relates to the use of UV-absorbers in a recording material. However, there is a problem with these materials in that they are not polymeric and may tend to wander out of the layer. 
     U.S. Pat. No. 5,384,235 relates to the use of polymeric UV-absorbers in a silver halide color photographic element. However, there is no disclosure in this patent of the use of these materials in an ink jet recording system. 
     U.S. Pat. No. 6,045,917 relates to the use of cationic mordants in an ink jet image-recording layer. However, there is a problem with this element in that images formed in the image-receiving layer have poor light stability, as will be shown hereafter. 
     It is an object of this invention to provide an ink jet printing method using anionic dyes suitable for use in aqueous inks for ink jet printing that will provide images with better Dmax density and light stability. 
     SUMMARY OF THE INVENTION 
     This and other objects are achieved in accordance with this invention which relates to an ink jet printing method, comprising the steps of: 
     A) providing an ink jet printer that is responsive to digital data signals; 
     B) loading the printer with an ink jet recording element comprising a support having thereon the following layers in order: 
     i) a base layer comprising a polymeric binder and a polymeric mordant; and 
     ii) an overcoat layer comprising a polymeric UV-absorbing material; 
     C) loading the printer with an ink jet ink composition comprising water, a humectant, and a water-soluble dye; and 
     D) printing on the overcoat layer using the ink jet ink in response to the digital data signals. 
     It has been found that use of the above dyes and image-receiving layer provides excellent Dmax density and light stability. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Any water-soluble dye may be used in the composition employed in the method of the invention such as a dye having an anionic group, e.g., a sulfo group or a carboxylic group. The anionic, water-soluble dye may be any acid dye, direct dye or reactive dye listed in the COLOR INDEX but is not limited thereto. Metallized and non-metallized azo dyes may also be used as disclosed in U.S. Pat. No. 5,482,545, the disclosure of which is incorporated herein by 09/202043, the disclosures of which are incorporated herein by reference. In a preferred embodiment, the anionic, water-soluble dye which may be used in the composition employed in the method of the invention is a metallized azo dye, a non-metallized azo dye, a xanthene dye, a metallophthalocyanine dye or a sulfur dye. Mixtures of these dyes may also be used. Examples of dyes that may be used in the invention are as follows:                           
     The dyes described above may be employed in any amount effective for the intended purpose. In general, good results have been obtained when the dye is present in an amount of from about 0.2 to about 5% by weight of the ink jet ink composition, preferably from about 0.3 to about 3% by weight. Dye mixtures may also be used. 
     In a preferred embodiment of the invention, the polymeric UV-absorbing material comprises the following repeating units:                           
     wherein: 
     R 1  represents H or CH 3 ; 
     R 2  represents H, halogen, alkoxy or a straight chain or branched alkyl group having from 1 to about 8 carbon atoms; 
     R 3  represents H, Cl, alkoxy or an alkyl group having from 1 to about 4 carbon atoms; 
     X represents COO, CONH or aryl; and

     The UV absorbing repeating units illustrated in Table 1 above can also be polymerized in the presence of two or more comonomers. For example, a combination of ethyl acrylate and acrylamido-2,2′-dimethyl propane sulfonic acid monomers can be copolymerized with UV absorbing repeating unit UV-1 above. Specific examples of polymeric UV absorbing materials useful for this invention are summarized below: 
     UVL-1: poly-(UV-1)-co-ethyl acrylate-co-2-sulfo-1,1-dimethylethylacrylamide, sodium salt (1:1:0.05 molar ratio) 
     UVL-2: poly-(UV-2)-co-ethyl acrylate-2-sulfo-1,1-dimethylethylacrylamide, sodium salt (1:1:0.05 molar ratio) 
     UVL-3: poly-(UV-3)-co-butyl acrylate-co-2-sulfo-1,1dimethylethyl acrylamide sodium salt (1:2:0.05 molar ratio) 
     The polymeric UV-absorbing materials employed in the invention can be used in an amount of from 0.05 to about 4.0 m 2 , preferably from about 0.20 to about 1.5 g/m 2 .

No. 5,244,861. Opaque supports include plain paper, coated paper, synthetic paper, photographic paper support, melt-extrusion-coated paper, and laminated paper, such as biaxally oriented support laminates. Biaxally oriented support laminates are described in U.S. Pat.

These biaxally oriented supports include a paper base and a biaxially oriented polyolefin sheet, typically polypropylene, laminated to one or both sides of the paper base. Transparent supports include glass, cellulose derivatives, e.g., a cellulose ester, cellulose triacetate, cellulose diacetate, cellulose acetate propionate, cellulose acetate butyrate; polyesters, such as poly(ethylene terephthalate), poly(ethylene naphthalate), poly(1,4-cyclohexanedimethylene terephthalate), poly(butylene terephthalate), and copolymers thereof; polyimides; polyamides; polycarbonates; polystyrene; polyolefins, such as polyethylene or polypropylene; polysulfones; polyacrylates; polyetherimides; and mixtures thereof. The papers listed above include a broad range of papers, from high end papers, such as photographic paper to low end papers, such as newsprint. 
     The support used in the invention may have a thickness of from about 50 to about 500 μm, preferably from about 75 to 300 μm. Antioxidants, antistatic agents, plasticizers and other known additives may be incorporated into the support, if desired. In a preferred embodiment, paper is employed. 
     In order to improve the adhesion of the image-recording layer to the support, the surface of the support may be subjected to a corona-discharge-treatment prior to applying the image-recording layer. 
     In addition, a subbing layer, such as a layer formed from a halogenated phenol or a partially hydrolyzed vinyl chloride-vinyl acetate copolymer can be applied to the surface of the support to increase adhesion of the image recording layer. If a subbing layer is used, it should have a thickness (i.e., a dry coat thickness) of less than about 2 μm. 
     The image-recording layer may be present in any amount that is effective for the intended purpose. In general, good results are obtained when it is present in an amount of from about 2 to about 60 g/m 2 , preferably from about 6 to about 40 g/m 2 , which corresponds to a dry thickness of about 2 to about 50 μm, preferably about 6 to about 40 μm. 
     The overcoat layer may be present in any amount that is effective for the intended purpose. In general, good results are obtained when it is present in an amount of from about 1.1 to about 10.7 g/m 2 , preferably from about 1.6 to about 5.4 g/m 2 , which corresponds to a dry thickness of about 1.0 to about 10 μm, preferably about 1.5 to about 5 μm.

     260 g of deionized water, 2.26 g of 20% sodium N-methyl-N-oleoyltaurate (surfactant Igepon T-77(®), and 26 g of acetone were mixed in a 500 mL, 4-necked round bottom flask equipped with a mechanical stirrer, nitrogen inlet, and condenser. The flask was immersed in a constant temperature bath at 80° C. and heated for 30 minutes with nitrogen purging through. The monomer solution was composed of 6.46 g of 2-(2′-hydroxy-5-methacrylyloxyethylphenyl)-2H-benzotriazole (0.02 mole), 2.00 g of ethylacrylate (0.02 mole), 0.23 g of 2-sulfo-1,1-dimethylethylacrylamide, sodium salt (0.001 mole) and 130 mL of N,N-dimethylformamide. The co-feed solution was made of 0.9 g of Igepon T-77® (20%), 1.8 g of sodium persulfate, and 20 g of deionized water. 3.91 g of 5% potassium persulfate was added to the reactor and stirred for 3 minutes. The monomer and co-feed solution were pumped into the reactor over 4 hours. The polymerization was continued for 8 hours. The latex was cooled, filtered and dialyzed against distilled water overnight. The latex was then concentrated down by an Amicon Ultrafiltration unit to the desirable concentration.

     The above results show that the recording elements E-6 through E-11 of the invention, as compared to the control recording elements C-4 and C-7, gave higher % retained densities after high intensity daylight fading. In addition, recording elements E-6 through E-9 gave higher Dmax densities than control recording elements C-4 through C-7. 
     Example 5 
     Preparation of a Water Soluble, Anionic Dye Ink Set, I-3 Through I-5 
     The Yellow ink jet ink I-3 was prepared using a standard formulation with Direct Yellow 132 (Dye 1 above, Projet Yellow 1G®, Zeneca Specialties, 10% solution in water) as the dye. The magenta ink I-4 was prepared using a standard formulation for Dye 3 above (see Dye 6 from U.S. Pat. No. 6,001,161 for specifics). The cyan ink jet ink I-5 was prepared using a standard formulation with Direct Blue 199 (see Dye 4 above, Duasyn Turquoise Blue FRL-SF® from Clariant Corp., 10% solution in water) as the dyes. 
     The standard formulations used for these inks include: 2-pyrrolidinone (3%); tri(ethylene glycol) (5%); glycerin (4%); Dowanol DB (2.5%) and Surfynol 465® (0.5%). For I-4, triethanolamine (0.25%) was also added. The dye concentrations for each ink were based on solution absorption spectra and chosen such that the final ink, when diluted 1:1000, would yield a transmission optical density of approximately 1.0. The percentages for each dye used are summarized in Table 5 Below.

     Printing 
     Elements E-6 through E-9 and control elements C-4 through C-7 from Example 4 were printed using a Lexmark Z51® ink jet printer using inks I-3 through I-5 described above. After printing, all images were allowed to dry at room temperature overnight, and the densities were measured at all steps using an X-Rite 820® densitometer. The images were then subjected to a high intensity daylight fading test for 2 weeks, 50Klux, 5400° K., approximately 25% RH. The Status A reflection densities for the single colors (yellow, magenta and cyan) and the 2 (red, green, and blue) and 3 (neutral) color combinations at 50% coverage were compared before and after fade and a percent dye retained for each was recorded. The results can be found in Tables 6 through 8 below.

     The above results show that the recording elements E-6 through E-7 of the invention, as compared to the control recording elements C-4 and C-5, gave higher % retained density after high intensity daylight fading for all color combinations. Although recording elements E-8 through E-9 of the invention showed no advantage over control recording elements C-6 and C-7 in the single colors (see Table 8), they showed higher % retained densities for most 2 and 3-color combinations (see data in Tables 7 and 8). 
     The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
