An improved silver halide colour photographic material comprises a support with at least one silver halide photographic emulsion layer on it. The silver halide emulsion layer contains a dispersion of oleophilic fine particles (1) made up of at least one diffusion-resistant, oil-soluble coupler (2) and at least one water-immiscible coupler solvent (3). (2) can couple with the oxidn. prod. of an aromatic prim. amine developing agent to form a non-diffusible dye. The m.pt. and b.pt. of (3) are 100 deg.C or lower and 140 deg.C or higher, respectively. The oil soluble coupler (2) has formulae (Cp-I), (Cp-II) or (Cp-III). The dispersed oleophilic fine particles are prepd. by emulsifying and dispersing a soln. of a mixt. which consists of at least one coupler, at least one coupler solvent and at least one water-insol. and organic solvent-soluble homo- or copolymer (4). (4) has repeat units which have no acid gps. in the main or side chain (at least 35 mol%). |
