SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL CONTAINING IMIDAZOPYRAZOLE TYPE COUPLER AND IMAGE FORMING METHOD USING THIS COUPLER

摘要

PURPOSE: To obtain high color reproduction performance and high sensitivity and superior color developing density. ;CONSTITUTION: The silver halide color photographic sensitive material containing the imidazo[1,2-b]pyrazole type coupler represented by formula I is developed with a developing solution containing an aromatic primary amine in the presence of this coupler. In formula I, R₁ is H, alkyl, alkoxy, aryloxy, or aryl; R₂ is alkoxy, aryloxy, or amino; and R₃ is H or a group to be released by coupling with the oxidation product of an aromatic primary amine color developing agent.;COPYRIGHT: (C)1993,JPO&Japio
