Abstract
Abstract A silver halide color photographic light-sensitive material comprised of a support having thereon a silver halide emulsion layer containing a cyan color image forming polymer coupler latex is disclosed. The cyan color image forming polymer coupler latex is comprised of at least one repeating unit capable of forming a dye upon coupling with an oxidation product of an aromatic primary amine developing agent represented by the general formula (Ia) and at least one repeating unit represented by the general formula (II): ##STR1## the substituents within the general formulae are disclosed within the specification. The cyan color image forming polymer coupler latex has excellent color forming properties and the silver halide color photographic light-sensitive material which contains the latex provides a photograph in which the occurrence of color stain due to light is substantially prevented. A method of forming a color image using the silver halide color photographic light-sensitive material is also described.
