PURPOSE:To improve the sensitivity of all red sensitive silver halide emulsion layers and to improve simultaneously sharpness and inter-image effect by incorporating monodisperse silver halide particles into at least one layer of silver halide emulsion layers having high blue sensitivity, high green sensitivity and high red sensitivity. CONSTITUTION:The blue sensitive silver halide emulsion layer, green sensitive silver halide emulsion layer and red sensitive silver halide emulsion layer are provided on a base. The respective photosensitive silver halide emulsion layers consist of plural layers having different sensitivities. The constitution in which at least the red sensitive silver halide emulsion layer having high sensitivity is provided between the green sensitive silver halide emulsion layer having the high sensitivity and the green sensitive silver halide emulsion layer having the sensitivity lower than the sensitivity of the high green sensitive silver halide emulsion layer is satisfactory. The representative embodiment thereof is constituted by coating a low-sensitivity RG layer unit, coating a high-sensitivity RG layer unit on the low-sensitivity RG layer unit and coating the high-sensitivity B layer unit on the high-sensitivity RG layer unit. |
