Abstract

Abstract The stability of a cyan dye image formed by phenol and naphthol couplers is improved with respect to "dark fading" by incorporating in the silver halide color photographic material in which the dye image is formed at least one 2-phenyl benzotriazole compound having in the 2'-position an --OR group wherein R is an organic residue.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 160 words
A silver halide color photographic material comprising a support and a silver halide light-sensitive layer containing a phenol or naphthol cyan coupler and a 2-phenyl benzotriazole compound having in the 2'-position an --OR group wherein R is an organic residue wherein said 2-phenyl benzotriazole compound is represented by the formula: ##STR10## wherein R represents an alkyl, alkenyl, cycloalkyl, aryl, aralkyl, acyl, alkylsulfonyl, or arylsulfonyl group, an N-substituted carbamoyl or sulfamoyl group, or a oxalyl, oxamoyl, oxycarbonyl or oxaacetyl group having an alkyl, aryl or aryloxy group; R 1 , R 2 , R 3 , R 4 and R 5 each represent hydrogen, halogen, an alkyl, alkenyl, aryl, aralkyl, alkoxy, aryloxy, acyloxy, alkylthio, arylthio, monoalkylamino, dialkylamino, acylamino, sulfonamido, or nitro group, the residue of a sulfonic acid or the ester or salt thereof, the residue of a carboxylic acid or the ester or salt thereof; and R 4 and R 5 can cooperatively form a 5- or 6-membered carbocyclic ring.
Claim 2
Dependent Claim 160 words
A silver halide color photographic material comprising a support and a silver halide light-sensitive layer containing a phenol or naphthol cyan coupler and a 2-phenyl benzotriazole compound having in the 2'-position an --OR group wherein R is an organic residue wherein said 2-phenyl benzotriazole compound is represented by the formula: ##STR10## wherein R represents an alkyl, alkenyl, cycloalkyl, aryl, aralkyl, acyl, alkylsulfonyl, or arylsulfonyl group, an N-substituted carbamoyl or sulfamoyl group, or a oxalyl, oxamoyl, oxycarbonyl or oxaacetyl group having an alkyl, aryl or aryloxy group; R 1 , R 2 , R 3 , R 4 and R 5 each represent hydrogen, halogen, an alkyl, alkenyl, aryl, aralkyl, alkoxy, aryloxy, acyloxy, alkylthio, arylthio, monoalkylamino, dialkylamino, acylamino, sulfonamido, or nitro group, the residue of a sulfonic acid or the ester or salt thereof, the residue of a carboxylic acid or the ester or salt thereof; and R 4 and R 5 can cooperatively form a 5- or 6-membered carbocyclic ring.
Claim 3
Dependent Claim 18 words
The color photographic material according to claim 1 wherein the photographic material further comprises 2,5-di-octyl-hydroquinone, 2,5-di-tert.amyl-hydroquinone or 2,5-di-tert.butyl-hydroquinone.
