ABSTRACT:
A method for processing a silver halide color photosensitive material, which comprises developing a silver halide color photosensitive material containing at least one compound selected from the group consisting of compounds represented by formula [A], bis or tris compounds and polymers derived therefrom, and alkali unstable precursors thereof, in a color developer which is replenished at a rate of not more than 9 ml per 100 cm.sup.2 of the silver halide color photosensitive material; ##STR1## wherein R.sub.a and R.sub.b each represents a hydrogen atom, a halogen atom, --SO.sub.3 M, --COOM (wherein M represents H, an alkali metal atom or NH.sub.4), an alkyl group, an acylamino group, an alkoxy group, an aryloxy group, an alkythio group, an arylthio group, a sulfonyl group, an acyl group, a carbamoyl group or a sulfamoyl group and they may together form a carbon ring; X represents a --CO-- group or a --SO.sub.2 -- group; R.sub.c represents an alkyl group, an aryl group, a heterocyclic group, a cycloalkyl group, an alkoxy group, an aryloxy group or an amino group; and the total number of carbon atoms of R.sub.a, R.sub.b and R.sub.c is at least 10.
