Description

field of invention

[0001] This invention relates to developer solutions and concentrated compositions thereof for use in silver halide color photographic materials, processes using the same, and in particular to developer solutions for use in silver halide color photographic materials when rapidly or in It is capable of inhibiting sedimentation or tar-staining caused on processing tanks or roll stands when processed at low replenishment rates, even concentrated developer compositions that do not form deposits when dissolved at relatively high concentrations, and how to use it. Background of the invention

[0002] In general, to form a color image by processing a silver halide color photographic material, the photographic material is imagewise exposed and developed with a developer solution containing a color developing agent of the p-phenylenediamine type in which the silver halide is reduced to silver and simultaneously oxidizing the color developing ag...
