Abstract
A process for processing a silver halide color reversal photographic light-sensitive material is disclosed, which comprises developing an imagewise exposed silver halide color reversal photographic light-sensitive material with a black-and-white developer containing at least one compound selected from the compounds of Group A, at least one compound selected from the compounds of Group B, and preferably further at least one compound selected from the compounds of Group C, wherein PA0 Group A consists of organic heterocyclic compounds represented by formulae (A-I), (A-II), (A-III), and (A-IV) ##STR1## Group B consists of benzoimidazole, indazole, benzotriazole, benzooxazole and benzothiazole compounds, not containing a thiol group, a thioether bond, a thioketone group, or a disulfide bond. PA0 Group C consists of compounds represented by formulae (C-I) and (C-II). ##STR2## wherein the symbols are as defined in the appended claims.
