ABSTRACT:
A silver halide color photographic light-sensitive material is disclosed. The material is comprised of a support base having thereon a silver halide emulsion layer containing a cyan dye-forming oleophilic polymer coupler. The polymer coupler is comprised of three repeating units including a repeating unit of a cyan coupler corresponding to general formula (I), an ethylene type unsaturated monomer repeating unit corresponding to general formula (II) which contains an acid component and an ethylene type unsaturated monomer repeating unit corresponding to general formula (III). The cyan dye-forming oleophilic polymer coupler is present in the form of a dispersed product, said polymer coupler having been dissolved in an organic solvent followed by emulsion dispersion of a gelatine aqueous solution in the presence of a surfactant. The general formulae and their substituents are described in the specification. By utilizing the particularly disclosed polymer coupler, the material forms a color image having excellent fastness which respect to heat and wet heat when the image is in the form of a color photograph after development. The novel cyan color image forming oleophilic polymer coupler also makes it possible to obtain remarkably excellent color forming property in the photographic image.
