发明名称 Silver halide color photographic materials
摘要 Disclosed is a silver halide color photographic material comprising a silver halide emulsion layer on a support, wherein said layer contains a dispersion of fine oleophilic grains, which grains contain at least one nondiffusible oil-soluble cyan coupler capable of forming a substantially nondiffusible dye by coupling with the oxidation product of an aromatic primary amine developing agent and at least one coupler solvent which is immiscible with water and has no aromatic group in the molecule and which has a melting point of 100 DEG C. or lower and has a boiling point or decomposition point of 140 DEG C. or higher. As the characteristic feature of the invention, the dispersion of said fine oleophilic grains is formed by emulsifying and dispersing a mixture solution comprising at least one of the coupler, at least one of the coupler solvent and at least one water-insoluble and organic solvent-soluble homopolymer or copolymer. By the combination of the coupler, coupler solvent and polymer, the light fastness and dark fastness of the photographic material is improved. In particular, the stability of the coating composition is improved, and the color balance of the color image formed may be maintained well after being stored even under high temperature and high moisture conditions.
