ABSTRACT:
In a silver halide color photographic photosensitive material, having a red, a green and a blue light-sensitive emulsion layer on a support, each emulsion containing a nondiffusible image forming coupler, improvement is attained by providing a layer structure in which at least one of the red, the green and the blue light-sensitive emulsion layer is separated into a high sensitivity silver halide emulsion layer and a low sensitivity silver halide emulsion layer, both layers having photosensitive regions in substantially the same spectral region, by an intermediate layer and incorporating at least one kind of DIR compounds represented by formula (I) defined in the specification in at least one layer of the high sensitivity silver halide emulsion layer, the low sensitivity silver halide emulsion and the intermediate layer.
