Abstract
A silver halide color photographic material is described, which comprises a support having provided therein at least a blue-sensitive emulsion layer, a green-sensitive emulsion layer and a red-sensitive emulsion layer, with the blue-sensitive emulsion layer comprising at least two layers differing in sensitivity, one of which is the highest sensitive emulsion layer containing at least one yellow-dye-forming coupler represented by the general formula (I), and the other of which is the lowest sensitive emulsion layer containing at least one yellow-dye-forming coupler represented by the general formula (II), whereby a yellow dye image having high maximum density and excellent in sharpness, graininess and light fastness can be produced: ##STR1##
Claims13
A silver halide color photographic material prising a support having provided thereon at least a blue-sensitive emulsion layer, a green-sensitive emulsion layer and a red-sensitive emulsion layer, said blue-sensitive emulsion layer comprising at least two layers differing in sensitivity, one of which is the highest sensitive blue-sensitive emulsion layer containing at least one yellow-dye-forming coupler represented by the general formula (I), and the other of which is the lowest sensitive blue-sensitive emulsion layer containing at least one yellow-dye-forming coupler represented by the general formula (V):
- ##STR125## wherein R.sub.1 represents a tertiary alkyl group;
- R.sub.2 represents a halogen atom, an alkoxy group, or a hydrogen atom;
- R.sub.3 represents an alkoxycarbonyl group, an aryloxycarbonyl group, an alkylsulfonamido group, an arylsulfonamido group, or an acylamino group;
- R.sub.4 represents a hydrogen atom, a halogen atom, an alkoxy group, an alkyl group, or an acylamino group;
- R.sub.5 represents an arylsulfonyl group, an alkylsulfonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a cyano group, an acyl group, an acylamino group, an alkylsulfamoyl group, an arylsulfamoyl group, an alkylsulfonamido group, an arylsulfonamido group, an alkoxysulfonyl group, an aryloxysulfonyl group, an alkylcarbamoyl group, an arylcarbamoyl group, a carboxyl group, or a nitro group;
- and R.sub.6 represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a hydroxy group, an acylamino group, an alkylsulfonamino group, an arylsulfonamino group, a carboxyl group, or an alkoxycarbonyl group;
- ##STR126## wherein R.sub.17 represents an unsubstituted or substituted alkoxycarbonyl group or an unsubstituted alkylsulfonamido group;
- and Z.sub.2 represents atoms necessary to form a 5- or 6-membered ring.
A silver halide color photographic material as claimed in claim 7, wherein R.sub.17 represents a straight or branched chain, unsubstituted alkoxycarbonyl group having 10 to 18 carbon atoms or a straight or branched chain, unsubstituted alkylsulfonamido group having 8 to 20 carbon atoms, and Z.sub.2 represents non-metallic atoms necessary to form a hydantoin nucleus.
