Abstract

Abstract A novel color stain inhibitor is disclosed, which is a compound comprising a phenol or naphthol ring substituted by at least one substituted or unsubstituted sulfamoyl group. Preferred examples of these compounds are represented by the general formula (I): ##STR1## wherein R 1 , R 2 , R 3 and Q are as defined herein. In light-sensitive materials containing the color stain inhibitors of the present invention, color stain is efficiently prevented.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 36 words
A color photographic silver halide light-sensitive material characterized by containing as a color stain inhibitor a compound comprising a phenol or naphthol ring with at least one substituted or unsubstituted sulfamoylamino group substituted in the ring.
Claim 2
Dependent Claim 36 words
A color photographic silver halide light-sensitive material characterized by containing as a color stain inhibitor a compound comprising a phenol or naphthol ring with at least one substituted or unsubstituted sulfamoylamino group substituted in the ring.
Claim 3
Dependent Claim 166 words
The material as claimed in claim 1, wherein the compound is represented by the general formula (I): ##STR10## wherein: R 1 is a hydrogen atom, a halogen atom, or an alkyl group, an alkoxyl group, an acylamino group, an alkylthio group, an alkoxycarbonyl group, an aryloxycarbonyl group, a sulfamoylamino group, a carbamoylamino group, an arylsulfoneamide group, an alkylsulfoneamide group, an acyl group, a sulfonyl group, or a carbamoyl group, which all may be substituted or unsubstituted; R 2 and R 3 are each an arylsulfonyl group, an alkylsulfonyl group, or a sulfamoyl group and may be substituted or unsubstituted, provided that when R 1 is not a substituted or unsubstituted sulfamoylamino group, at least one of R 2 and R 3 is a substituted or unsubstituted sulfamoyl group; and Q represents atoms to form a phenol ring in combination with a ring substituted with a OH group, or an atomic group to form a naphthol ring in combination with a ring substituted with a OH group.
