发明名称 METHOD FOR PROCESSING SILVER HALIDE PHOTO-SENSITIVE MATERIAL
摘要 Processing an imagewise exposed light-sensitive silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer containing silver halide grains which are sensitized with a sensitizing dye represented by general formula ¢I!: ¢I! (wherein, Z1 and Z2 independently represent a group of atoms necessary to complete a heterocyclic ring consisting of a thiazole, a benzothiazole, a selenazole, a benzoselenazole, a naphthoselenazole, a benzimidazole, a naphthoimidazole, a pyridine or a quinoline ring, wherein said heterocyclic ring may have a substituent; R1 and R2 are independently selected from a group consisting of an alkyl group, an alkenyl group and an aryl group; R3 is selected from a group consisting of hydrogen atom, a methyl group and an ethyl group; X1 is an anion and 1 is 0 or 1). Processing takes place with a color developer solution containing an aromatic primary amine color developing agent in the presence of at least one hydroxylamine derivative represented by general formula ¢II! or a water soluble acid salt thereof: ¢II! (wherein, R21 and R22 are independently selected from a group consisting of a hydrogen atom and an alkyl group having 1 to 4 carbon atoms which may have a substituent provided that R21 and R22 are not simultaneously hydrogen atoms and that R21 and R22 may be combined with each other to form a nitrogen-containing ring; and at least one nitrogen-containing heterocyclic mercapto-compound. This enables to reduce pollution load by removing benzyl alcohol from the color developer. By carrying out the color developing with a specific hydroxylamine derivative, the dye image is rapidly formed and the fog is restrained. In addition, this type of processing is associated with reduced sensitivity or gradation fluctuation due to a change of pH.
