Patent number: 5098805Abstract: There is provided a color photograph improved in preservability that has been obtained by making chemically inactive the aromatic amine type color developing agents and their oxidized product that remains in the silver halide photographic materials after color development processing. The color photograph exhibits excellent performance in that its white background can be prevented from discoloring even during long-term storage or display, and deterioration of a dye image caused by the remaining color developing agent being taken into the photographic material after the color development, bleaching, and fixing processes, or due to its oxidized product, can be prevented.Type: GrantFiled: March 19, 1990Date of Patent: March 24, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Nobuo Furutachi, Osamu Takahashi, Masakazu Morigaki

Patent number: 5077179Abstract: A method for processing silver halide photosensitive materials comprises replenishing each of replenishers to water washing process and/or stabilization process in an amount of 1 to 50 times the volume of a solution carried over from a bath preceding the water washing process and/or the stabilization process per unit area of the photosensitive material and limiting the amount of calcium compounds included in a layer for constituting photograph of the photosensitive material to not more than 25 mg/m.sup.2 on the basis of the weight of elemental calcium. The method makes it possible to effectively suppress the contamination of the processed photosensitive materials, the increase in turbidity of the water washing and/or stabilization bath solutions and the proliferation of bacteria or molds in these baths. These effects are further enhanced by reducing the amount of calcium and magnesium present in the replenishers for washing and/or stabilization.Type: GrantFiled: October 9, 1987Date of Patent: December 31, 1991Assignee: Fuji Photo Film Co., Ltd.Inventors: Akira Abe, Yoshihiro Fujita, Nobuo Sakai

Patent number: 5055381Abstract: In a method for processing silver halide photosensitive materials comprising developing an exposed silver halide photosensitive material, fixing the developed material and washing it with a washing water, the amount of calcium and magnesium compounds present in the replenishing washing water is reduced to not more than 5 mg/l on the basis of the weight of elemental calcium or magnesium and washing water is replenished in an amount of 1 to 50 times the volume of liquid carried over by the photosensitive material from a bath preceding the washing bath per unit area thereof or that the replenishing washing water is introduced into a washing bath after reducing the amount of calcium and magnesium compounds to the range mentioned above and sterilizing the same. The method makes it possible to substantially reduce the amount of washing water while reliably suppressing turbidity and proliferation of microorganisms in the washing water during and after completion of processing.Type: GrantFiled: June 3, 1987Date of Patent: October 8, 1991Assignee: Fuji Photo Film Co., Ltd.Inventors: Akira Abe, Yoshihiro Fujita, Toshio Koshimizu
