Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
A method of processing an exposed light-sensitive silver halide color photographic material by a developer, which method comprises conducting said processing in the presence of a coupler represented by the following formula A -- X -- C.sub.n F.sub.2n H wherein A is the residue of a coupler which is selected from the group consisting of benzoylacetanilide and pivaloylacetanilide yellow couplers, 1-phenyl-5-pyrazolone, indazolin-3-one and pyrazolo-benzimidazole magenta couplers, and phenol and naphthol cyan couplers; X is a biradical which is selected from the group consisting of ##STR5##provided that the left bond of the group is attached to A while the right bond is connected to --C n F 2n H; and n is an integer of 1 to 18 inclusive; further provided that X is not --NHCO-- of which N is attached to A when the following three conditions are simultaneously met, one of the conditions being that A is a phenol or naphthol cyan coupler residue, another being that the hydrogen atom of --C n F 2n H is at the ω-position thereof, the other being that n is an even number of 2 to 14.
Claim 2
Independent Claim
185 words
A method of processing an exposed light-sensitive silver halide color photographic material by a developer, which method comprises conducting said processing in the presence of a coupler represented by the following formula A -- X -- C.sub.n F.sub.2n H wherein A is the residue of a coupler which is selected from the group consisting of benzoylacetanilide and pivaloylacetanilide yellow couplers, 1-phenyl-5-pyrazolone, indazolin-3-one and pyrazolo-benzimidazole magenta couplers, and phenol and naphthol cyan couplers; X is a biradical which is selected from the group consisting of ##STR5##provided that the left bond of the group is attached to A while the right bond is connected to --C n F 2n H; and n is an integer of 1 to 18 inclusive; further provided that X is not --NHCO-- of which N is attached to A when the following three conditions are simultaneously met, one of the conditions being that A is a phenol or naphthol cyan coupler residue, another being that the hydrogen atom of --C n F 2n H is at the ω-position thereof, the other being that n is an even number of 2 to 14.
Claim 3
Dependent Claim
25 words
A method according to claim 1, wherein the photographic material comprises the coupler whereby the processing is carried out in the presence of the coupler.
Claim 4
Dependent Claim
24 words
A method according to claim 1, wherein the developer comprises the coupler whereby the processing is carried out in the presence of the coupler.
