Abstract

A process for processing a color photographic silver halide light-sensitive material comprising processing the color photographic silver halide light-sensitive material with a color developer containing at least one compound represented by the general formula (I): ##STR1## wherein X is a hydrogen atom, an alkali metal atom, an ammonium group, an alkyl group, or an aryl group; Y is a substituent on the phenyl group and is a halogen atom, an alkyl group, an alkoxy group, an amino group, a hydroxyl group, a nitro group, a sulfonic acid group or a carboxylic acid group; and n is 0, 1, 2, 3 or 4. Color developers containing the compounds of the general formula (I) have greatly increased stability and thus even after long-term storage, can be used to produce developed materials having superior photographic properties.
