Abstract

A silver halide color photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer, the color photographic light-sensitive material containing at least one kind of 2-equivalent magenta coupler represented by the following general formula (Ia): ##STR1## wherein Ar represents phenyl substituted with at least one halogen, alkyl, alkoxy, alkoxycarbonyl or cyano; Y represents acylamino or anilino; and Z represents a group capable of being released by coupling, and at least one kind of piperidine compound represented by the following general formula (II): ##STR2## wherein R.sub.1 represents hydrogen or alkyl; R.sub.2 represents alkyl, hydroxyalkyl, alkenyl alkynyl or benzyl; W represents hydrogen, alkyl, hydroxy, silyloxy, alkylamino, aryloxy, allyl, alkoxy, acylamino, sulfonamido, alkoxycarbonyl, carboxy, acyloxy or phosphoric acid oxy. The silver halide color photographic light-sensitive material can provide a good magenta color image without the occurrence of strain, even when the color photographic material is processed in a processing solution under the running condition.
