grain, great tonality, incredible sharpness and being capable of high contrast results. In particular the slowest speed film KB 25 was laid down as a single layer emulsion. The films were low cost but due to their soft emulsion were prone to scratching during processing as well as quality issues. DuPont kept the Adox trademark, transferring it to a subsidiary, Sterling Diagnostic Imaging, for its Adox brand X-ray films. DuPont still applies it to an industrial chemical, sodium chlorite. In 1999, Sterling was bought by the German company Agfa, and was absorbed into Agfa's Health Sciences unit. In this roundabout way, the Adox photographic trademark once again briefly became German. Agfa did not use the Adox trademark, and the mark was removed from the German Patent Office trademark registry in March, 2003. It was almost immediately revived by companies in Canada, the United States, and Fotoimpex in Germany. ADOX Fotowerke GmbH (2003 on) The current rights to the ADOX name were obtained in 2003 by Fotoimpex of Berlin, Germany, a company founded in 1992 to import photographic films and papers from former eastern Europe. In particular they imported the Efke KB films and sold them branded as 'ADOX CHS Art' thus finally re-uniting the ADOX name with the original Schleussner film formula. Fotoimpex established the ADOX Fotowerke GmbH film factory in Bad Saarow outside Berlin to convert and package their films, papers and chemicals using machinery acquired from the closed AGFA (Leverkusen, Germany) and Forte Photochemical Industry (Hungary) photographic plants. ADOX test-produced a slightly improved version of the original AGFA APX 400 as ADOX Pan 400 during 2010. After Fotokemikas closure in 2012 due to failure of the original film making machinery proving too expensive to repair, Fotoimpex had ADOX CHS II (100 ISO, equivalent to Efke KB 100) black and white film produced using modern cascade coating. This took priority over proposals to re-introduce Agfa APX 400. In February 2015 they purchased/obtained a long lease on the former Ilford Imaging, Switzerland (Ciba Geigy) machine E, medium scale coating line at Marly, Switzerland to coat photographic film and paper. Trial coating for ADOX CHS (II) was undertaken at Marly prior to its re-introduction in 2018. The plant has also been used for testing the proposed revival of Polywarmtone Paper last produced by Forte in Hungary. ADOX are also (2017–19) doubling the size of the film factory in Bad Saarow, Germany
