发明名称 SILVER HALIDE COLOR PHOTOGRAPHIC MATERIAL CONTAINING A PHENOL CYAN COUPLER AND METHOD OF IMAGE
摘要 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: <IMAGE> (I) <IMAGE> (II) R1, R4, and R5 represent aliphatic, aromatic or heterocyclic groups; R3 and R6 each represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group or an acylamino group, or R6 represents a group of non-metal atoms required to form, together with R5, a five or six membered nitrogen containing ring; R2 represents an aliphatic group; Y1 and Y2 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 R2, R3, Y1 or one group among R5, R6, and Y2.
