Abstract
Abstract An improved method for developing an exposed silver halide color photosensitive material is disclosed which comprises conducting the development in the presence of a cyan coupler. The coupler has, in the active position thereof, the following split-off group: ##STR1## WHEREIN R 1 is an aliphatic hydrocarbon residue, an aromatic hydrocarbon residue, or a heterocyclic ring residue; R 2 is an aliphatic hydrocarbon residue or an aromatic hydrocarbon residue; l is an integer of 0 to 4 inclusive.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
A method for developing an imagewise exposed silver halide color photosensitive material which comprises conducting the development in the presence of at least one of p-phenylenediamines and a phenol or naphthol cyan coupler having, in the active position thereof, the following split-off group: ##STR9## wherein R 1 is selected from the group consisting of alkyl, alkenyl, aryl, acyl, formyl, amino carbonyl group or a heterocyclic ring, said group and said ring may be substituted with a member selected from the group consisting of nitro; hydroxyl; amino; sulfo; substituted or unsubstituted alkyl, aryl, heterocyclic ring, alkoxy, arylazo, acylamino, or carbamoyl, said heterocyclic ring having 5 to 6 members and is selected from the group consisting of pyridyl, quinolyl, thienyl, piperidyl, imidazolyl and oxydiazolyl; R 2 is alkyl, alkenyl, aryl, acyl, formyl, or aminocarbonyl; and 1 is an integer of 0 to 4 inclusive.
Claim 2
Independent Claim
142 words
A method for developing an imagewise exposed silver halide color photosensitive material which comprises conducting the development in the presence of at least one of p-phenylenediamines and a phenol or naphthol cyan coupler having, in the active position thereof, the following split-off group: ##STR9## wherein R 1 is selected from the group consisting of alkyl, alkenyl, aryl, acyl, formyl, amino carbonyl group or a heterocyclic ring, said group and said ring may be substituted with a member selected from the group consisting of nitro; hydroxyl; amino; sulfo; substituted or unsubstituted alkyl, aryl, heterocyclic ring, alkoxy, arylazo, acylamino, or carbamoyl, said heterocyclic ring having 5 to 6 members and is selected from the group consisting of pyridyl, quinolyl, thienyl, piperidyl, imidazolyl and oxydiazolyl; R 2 is alkyl, alkenyl, aryl, acyl, formyl, or aminocarbonyl; and 1 is an integer of 0 to 4 inclusive.
Claim 3
Dependent Claim
