Abstract
Abstract A process for processing a silver halide color photographic material is described, which comrises processing a silver halide photographic material having on a support at least one silver halide photographic emulsion layer containing a silver bromide or silver chlorobromide emulsion in which tabular silver halide grains having main crystal planes parall to each other and a average aspect ratio of at least 5 account for at least 50% of the total projected area of the silver halide grains with a color developer containing 8 ml/liter or less of benzyl alcohol.
