SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE:To increase the resistance of a sensitive material to light and formalin and to improve the color developing property by incorporating a specified 1H- pyrazolo[3,2-c]-s-triazole type magenta coupler into a silver halide emulsion layer. CONSTITUTION:A compound having a tertiary alkyl group at the 3-position and an eliminable group other than a hydrogen atom at the 7-position as substituents is incorporated into a silver halide emulsion layer as a 1H- pyrazolo[3,2-c]-s-triazole type magenta coupler. A compound represented by the formula may be used as said compound. Since the silver halide emulsion layer contains the specified compound, the resistance of the resulting color photographic sensitive silver halide material to light and formalin is increased, and the color developing property can be improved.
