IPC: G03C7/30
Filed: 1987-02-12
Abstract: PURPOSE:To increase a developing speed and to prevent an increase in rereversal negative images and degradation in sensitivity by decreasing the silver chloride content in a blue sensitive layer as compared to other green sensitive and red sensitive layers and maximizing the total silver chloride content in a photosensitive material. CONSTITUTION:This photosensitive material has respectively at least one of red sensitive emulsion layers, green sensitive emulsion layers and blue sensitive emulsion layers formed by using internal latent image type silver halide emulsions which are previously not fogged on a base. The internal latent image type silver halide emulsions are the silver chlorobromide emulsion contg. substantially no silver iodide. The silver halide of the blue sensitive silver halide photosensitive layer is lower in the silver chloride content than the respective silver halides of the green sensitive silver halide photosensitive layer and red sensitive silver halide photosensitive layer. The developing speed is thereby increased; in addition, the generation of the rereversal negative images is low and the sensitivity is high.
