Abstract
A silver halide color photographic material having provided on a support at least one light-sensitive silver halide emulsion layer, wherein said photographic material contains a coupler of formula (I) and at least one coupler selected from the group consisting of couplers represented by formula (II) and (III), wherein the substituents are as defined herein the specification. ##STR1## The material has improved coloring capacity and color image fastness and fluctuation of the properties of the material due to variation of the processing conditions is reduced.
