ABSTRACT:
A light-sensitive silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material comprises at least one layer containing a 5-pyrazolone magenta coupler represented by general formula (I) and a non-color forming, diffusion-resistant carboxylic acid compound: ##STR1## wherein W represents an aryl group; Y represents a carbonamido group, a ureido group or an anilino group; and R represents an alkyl group, an aryl group or a heterocyclic group.
The silver halide color photographic material has high sensitivity, high color forming property, good formalin resistivity and good preservability, and provides magenta color images having good stability.
