COLOR DEVELOPER GRANULATED MATERIAL FOR SILVER HALIDE COLOR PHOTOGRAPHIC MATERIAL, GRANULATION METHOD THEREFOR, AND SOLID PROCESSING AGENT AND TABLET TYPE SOLID PROCESSING AGENT USING THE GRANULATED MATERIAL

摘要

PURPOSE: To prevent the deterioration of a paraphenylenediamine-based com pound during the manufacturing process of a coloring developer solid processing agent for a silver halide color photographic material and prevent the coloration of granular materials under high temperature and highly humid environment. ;CONSTITUTION: Regarding a coloring developer granulated material for a silver halide color photographic material having at least one kind of paraphenylenediamine-based compounds, the granulated material is a coloring developer granulated material a part of which contains at least one kind of compounds having the formula and which shows pH 5 or lower when dissolved in water and is used for a silver halide color photographic material. In the formula, L stands for an alkylene group, A for carboxyl, sulfonyl, etc., and R for hydrogen atom or an alkyl group.;COPYRIGHT: (C)1996,JPO
