Abstract
Abstract A silver halide color photographic light-sensitive material is described comprising a support having thereon a silver halide emulsion layer containing a 2-equivalent 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 formula (I) ##STR1## wherein R represents a hydrogen atom, a lower alkyl group containing from 1 to 4 carbon atoms or a chlorine atom; X represents --CONH--, --NH--, --NHCONH-- or --NHCOO--; Y represents --CONH-- or --COO--; A represents an unsubstituted or substituted alkylene group which may be a straight chain or a branched chain or an unsubstituted or substituted phenylene group; Ar represents an unsubstituted or substituted phenyl group; Za, Zb, Zc and Zd can each represent a methine group, a substituted methine group or -N═; m represents 0 or 1; and n represents 0 or 1. The 2-equivalent 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 provides a stable magenta image having 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.
