Silver halide photographic light-sensitive material

Claim 1

A silver halide photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer containing at least one coupler represented by the the following Formula I and a water soluble iridium salt in an amount of from 10 31 9 mol to 10 -3 mol per mol of silver halide; Formula I ##STR22## wherein X represents a halogen atom or a monovalent organic group capable of being split off upon coupling reaction with the oxidized product of a color developing agent; R 1 , R 2 and R 3 may be the same of different from each other and each represent a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alkinyl group, an aryl group, a heterocyclic group, an acyl group, a sulfonyl group, a sulfinyl group, a phosphonyl group, a carbamoyl group, a sulfamoyl group, a cyano group, a residue of spiro-compound, a residue of bridged hydrocarbon compound, an alkoxy group, an aryloxy group, a heterocyclic oxy group, a siloxy group, an acyloxy group, a carbamoyloxy group, an amino group, an acylamino group, a sulfonamido group, an imido group, an ureido group, a sulfamoylamino group, an alkoxycarbonylamino group, an aryloxycarbonyl amino group, an alkoxycarbonyl group, an alkylthio group, an aryloxycarbonyl group, an arylthio group or a heterocyclic thio group; and R 4 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an acylamino group, an alkylamino group, an anilino group, an alkoxycarbonyl group or an alkyl thio group; provided that at least one of R 1 , R 2 , R 3 and R 4 contains at least one group represented by the following Formula II; Formula II --R.sub.5 --SO.sub.2 --R.sub.6 wherein R 5 represents an alkylene group or an arylene group; and R 6 represents an alkyl group or an aryl group.
