ABSTRACT:
A silver halide color photographic material is disclosed having blue-sensitive, green-sensitive, and red-sensitive silver halide emulsion layers on a support, wherein said red-sensitive silver halide emulsion layer contains a dispersion of fine oleophilic grains formed by dispersing by emulsification a mixture comprising a water-insoluble and organic solvent-soluble homopolymer or copolymer and at least one coupler represented by formula (I) or formula (II), and the silver halide emulsion layer or non-light-sensitive layer of the material contains a dye represented by formula (III);
wherein formula (I) is represented by ##STR1## wherein R.sub.11 represents an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group; R.sub.12 represents an acylamino group or an alkyl group; R.sub.13 represents a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group, or R.sub.12 and R.sub.13 are bonded together to form a nitrogen-containing heterocyclic ring; Z.sub.11 represents a hydrogen atom, an alkyl group, an aryloxy group, an alkylthio group or an arylthio group;
formula (II) is represented by ##STR2## wherein R.sub.21 and R.sub.22 each represents a hydrogen atom, an alkyl group, a cycloalkyl group or an aryl group, provided that at least one of R.sub.21 and R.sub.22 is a substituent other than a hydrogen atom; R.sub.23 represents a hydrogen atom, a carbamoyl group, a sulfamyl group, an alkoxycarbonyl group or an aryloxycrbonyl group; Z.sub.21 represents a hydrogen atom, an alkoxy group, an aryloxy group, an alkylthio group or an arylthio group; X represents --CO-- or --SO.sub.2 --; and formula (III) is represented by ##STR3## wherein R.sub.1 and R.sub.2 each represents --COOR.sub.5 or ##STR4## R.sub.3 and R.sub.4 each represents a hydrogen atom or an alkyl group; R.sub.5 and R.sub.6 each represents a hydrogen atom, an alkyl group or an aryl group; Q.sub.1 and Q.sub.2 each represents an aryl group; X.sub.1 and X.sub.2 each represents a divalent linking group; Y.sub.1 and Y.sub.2 each represents a sulfo group or a carboxyl group; L.sub.1, L.sub.2 and L.sub.3 each represents a methine group; m.sub.1 and m.sub.2 each represents 1 or 2; n represents 0, 1 or 2; P.sub.1 and P.sub.2 each represents 0, 1, 2, 3 or 4; and s.sub.1 and s.sub.2 each represents 1 or 2.
The material forms a color image with less stain, which is stable for a long period of time; it contains a novel dye which may easily be discolored or dissolved out by photographic processing without having any bad influence on the photographic characteristics of the material; and it is excellent in the time-dependent storability.
