ABSTRACT:
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer containing a dispersion, said dispersion comprising oleophilic fine particles containing (a) at least one oil-soluble cyan coupler represented by formula (I) (described herein) capable of forming substantially non-diffusible cyan dye upon coupling with an oxidation product of an aromatic primary amine developing agent, and (b) a water-insoluble, organic solvent-soluble homopolymer or copolymer comprising not more than about 20% by weight of a repeating unit having an acid radical in the main chain or a side chain thereof, wherein the dispersion does not contain high-boiling point organic solvents. The photographic material provides color images excellent in preservability, particularly resistance to dark discoloration and light discoloration in good balance.
