ABSTRACT:
A light-sensitive silver halide color photographic material is disclosed. The light-sensitive material comprises a support and a silver halide emulsion layer and a non-light-sensitive hydrophilic colloid layer provided on the support. The emulsion layer comprises a mixture of at least two kinds of silver halide emulsions which different from each other in sensitivity. The emulsion layer contains a magenta coupler represented by Formula II and the non-light-sensitive layer contains a compound represented by formula II: ##STR1## wherein Ar is an aryl group; Y is a hydrogen atom or a substituent capable of releasing upon reaction with the oxidation product of a color developing agent; X is a halogen atom, an alkoxy group or an alkyl group; n is an integer of 0 to 4, Xs are the same or different when n is 2 or more; R is a strait chain or branched alkyl group having 1 to 20 carbon atoms, ##STR2## wherein R.sub.1 and R.sub.2 are each a secondary tertiary alkyl group, provided the total number of carbon atoms contained in R.sub.1 and R.sub.2 are 20 or more.
