Silver halide photographic light-sensitive material with black dye forming coupler |
摘要 |
A silver halide photographic light-sensitive material forming a black and white image is disclosed. The silver halide in the silver halide emulsion layer is silver chlorobromide having a silver chloride content of not less than 90 mol % and containing virtually no silver iodide; the emulsion layer contains a coupler selected from resorcinol-based dye-forming couplers and aminophenol-based dye-forming couplers, and gelatin in a coating weight of 1.0 to 1.5 g/m2. The silver halide photographic light-sensitive material is processed by color development to form a black and white image.
