Abstract
Abstract A silver halide color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing a magenta color image forming polymer coupler latex which is capable of forming a dye upon coupling with an oxidation product of an aromatic primary amine developing agent and which is a polymer or copolymer having a repeating unit derived from a monomer represented by the following general formula (I) ##STR1## wherein R represents a hydrogen atom, a lower alkyl group containing from 1 to 4 carbon atoms or a chlorine atom; and X represents a halogen atom, an acylamino group, a carbamoyl group, a sulfonamido group, a sulfamoyl group, a cyano group or an alkoxycarbonyl group and which is present at the 4-position or 5-position of the phenyl group. The magenta color image forming polymer coupler latex has a good color forming property and is capable of forming a dye with a high yield and without formation of undesired stains and fogs, and the silver halide color photographic light-sensitive material containing the magenta color image forming polymer coupler latex has good film strength and a reduced layer thickness and provides a stable magenta image having an improved sharpness and a good fastness to light, heat, and humidity. A method of forming a color image using the silver halide color photographic light-sensitive material is also described.
