ABSTRACT:
A silver halide color photographic material comprises at least one silver halide emulsion layer containing a substantially iodide free silver chlorobromide or silver chloride grain of which the silver chloride content is at least 90 mol. % and a color coupler. The color coupler is at least one compound represented by formula (I) or (II). The coupler is dispersed in the emulsion layer, as a dispersion of a fine lipophilic particle obtained by emulsification and dispersion of a solution obtained by dissolution of the coupler together with at least one homopolymer or copolymer which is insoluble in water and soluble in an organic solvent and a high boiling point organic solvent: ##STR1## R.sub.1, R.sub.4, and R.sub.5 represent aliphatic, aromatic or heterocyclic groups; R.sub.3 and R.sub.6 each represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group or an acylamino group, or R.sub.6 represents a group of non-metal atoms required to form, together with R.sub.5, a five or six membered nitrogen containing ring; R.sub.2 represents an aliphatic group; Y.sub.1 and Y.sub.2 each represents a hydrogen atom or a group which can be eliminated during a coupling reaction with the oxidized form of a developing agent. l represents the integer 0 or 1. Polymeric couplers consisting of dimers or greater units can be formed via one group from among R.sub.2, R.sub.3, Y.sub.1 or one group among R.sub.5, R.sub.6, and Y.sub.2.
