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 homopolymer or copolymer having a repeating unit derived from a monomer coupler represented by the following general formula (I): ##STR1## wherein R.sub.1 represents hydrogen, a lower alkyl group containing from 1 to 4 carbon atoms or a chlorine atom; R.sub.2 and R.sub.3, which may be the same or different, each represents an unsubstituted or substituted alkylene group which may be a straight chain or a branched chain, an unsubstituted or substituted arylene group or an unsubstituted or substituted aralkylene group; X represents --CONH-- or --COO--; Y represents --O--, --S--, --SO--, --SO.sub.2 --, --CONH-- or --COO--; Ar represents an unsubstituted or substituted phenyl group; R.sub.4 represents an unsubstituted or substituted anilino group, an unsubstituted or substituted acylamino group or an unsubstituted or substituted ureido group; l represents 0 or 1; m represents 0 or 1; and n represents 0 or 1.
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 improved graininess and 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.
