Abstract

Abstract A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein said material includes at least one magenta coupler of 1H-pyrazolo(1,5-b)(1,2,4)triazole type in which a substituted or unsubstituted aryloxy group is attached to the coupling active site to heighten coloring efficiency and speed, and further to ensure excellent light-fastness to the dye formed therefrom.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 43 words
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein said material includes at least one 1H-pyrazolo(1,5-b)(1,2,4)triazole magenta coupler in which a substituted or unsubstituted aryloxy group is attached to the coupling active site.
Claim 2
Dependent Claim 43 words
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein said material includes at least one 1H-pyrazolo(1,5-b)(1,2,4)triazole magenta coupler in which a substituted or unsubstituted aryloxy group is attached to the coupling active site.
Claim 3
Dependent Claim 172 words
A silver halide color photographic material as in claim 1, wherein the magenta coupler is represented by formula (I) ##STR14## wherein R 1 and R 2 each represents a hydrogen atom, a halogen atom, an aliphatic group, an aryl group, a heterocyclyl group, a cyano group, an alkoxy group, an aryloxy group, a heterocyclyoxy group, an acyloxy group, a carbamoyloxy group, a silyloxy group, a sulfonyloxy group, an acylamino group, an anilino group, a ureido group, an imido group, a sulfamoylamino group, a carbamoylamino group, an alkylthio group, an arylthio group, a heterocyclylthio group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonamido group, a carbamoyl group, an acyl group, a sulfamoyl group, a sulfonyl group, a sulfinyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; R 3 represents an aryl group; or R 1 or R 2 represents a divalent group including a simple bond through which the coupler forms a polymer, including a dimer; or R 3 represents an arylene group through which the coupler forms a polymer, including a dimer.
Claim 4
Dependent Claim 27 words
A silver halide color photographic material as in claim 2, wherein the aryl group represented by R 3 is an unsubstituted or substituted phenyl or naphthyl group.
Claim 5
Dependent Claim 124 words
A silver halide color photographic material as in claim 3, wherein the substituent of the substituted phenyl or naphthyl group is a halogen atom, an alkyl group, an aryl group, a heterocyclic group, a cyano group, an alkoxy group, an aryloxy group, a heterocyclyloxy group, an acyloxy group, a carbamoyloxy group, a silyloxy group, a sulfonyloxy group, an acylamino group, an anilino group, an amino group, a ureido group, an imido group, a sulfamoylamino group, an alkylthio group, an arylthio group, a heterocyclylthio group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonamido group, a carbamoyl group, an acyl group, a sulfamoyl group, a sulfonyl group, a sulfinyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a nitro group, a carboxyl group or a sulfo group.
Claim 6
Dependent Claim 74 words
A silver halide color photographic material as in claim 1, wherein the divalent group represented by R 3 when two coupler units of formula (I) form a bis compound through R 3 is a substituted or unsubstituted phenylene group, a naphthylene group, a biphenylene group, or a group represented by formula (II) ##STR15## wherein A represents a divalent group, R 4 represents a substituent group and n is an integer of 0 to 4.
Claim 7
Dependent Claim 56 words
A silver halide color photographic material as in claim 1, wherein the divalent group represented by R 1 or R 2 when the coupler forms a bis compound therethrough is a substituted or unsubstituted alkylene or phenylene group, or a --NHCO--R 5 --CONH-- group wherein R 5 represents a substituted or unsubstituted alkylene or phenylene group.
Claim 8
Dependent Claim 68 words
A silver halide color photographic material as in claim 1, wherein the divalent group represented by R 1 or R 2 when the coupler of formula (I) is present in a vinyl monomer is a combined group formed by a connecting group selected from a class consisting of a substituted or unsubstituted alkylene group, a substituted or unsubstituted phenylene group, --NHCO--, --CONH--, --O--, --OCO-- and an aralkylene group.
Claim 9
Dependent Claim 34 words
A silver halide color photographic material as in claim 1, wherein the coupler in the silver halide emulsion layer is present in a range of 0.003 to 0.5 mole per mole of silver halide.
