ABSTRACT:
A silver halide color photographic material having excellent color reproducibility and image storage stability, which comprises a support having thereon at least one silver halide photographic emulsion layer containing an emulsified dispersion of oleophilic fine particles obtained by dispersing a mixture solution containing at least one cyan coupler represented by formulae (I) or (II) and at least one water-insoluble and organic solvent-soluble polymer; ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each represents hydrogen, an aliphatic group, an aromatic group, a heterocyclic group, an aromatic amino group, a heterocyclic amino group, an aliphatic amino group, an acylamino group, a sulfonamido group, a carbamoyl group, a sulfamoyl group, a ureido group, an aliphatic oxycarbonyl group, an aromatic oxycarbonyl group, an aliphatic oxycarbonylamino group, an aromatic oxycarbonylamino group, a carboxy group, or a cyano group; and X.sub.1 and X.sub.2 each represents hydrogen or an atom or a group capable of being released by a coupling reaction with the oxidation product of a color developing agent; provided that R.sub.2 and X.sub.1 and R.sub.3 and R.sub.4 each may be linked to form a 5- to 7-membered ring; said coupler may form a dimer or higher polymer at R.sub.1, R.sub.2, or X.sub.1 or at R.sub.3, R.sub.4, or X.sub.2 ; excluding that R.sub.1 and R.sub.2 or R.sub.3 and R.sub.4, are a combination of atoms and/or groups selected from hydrogen atoms, carboxyl groups, and cyano groups; and when R.sub.3 and R.sub.4 combine with each other to form a 5- to 7-membered ring, the ring does not have two or more double bonds.
