Abstract
A silver halide color photographic photosensitive material comprising a base having thereon a non-photosensitive intermediate layer sandwiched between a high-sensitive silver halide emulsion layer and a low-sensitive silver halide emulsion layer both having a nondiffusion coupler that forms substantially the same color and having photosensitivity in substantially the same spectral region is disclosed. Said non-photosensitive intermediate layer has incorporated therein with a nondiffusion coupler that forms substantially the same color as that formed by the nondiffusion coupler contained in said high-sensitive emulsion layer and whose coupling speed is not greater than that of the nondiffusion coupler contained in said high-sensitive silver halide emulsion layer.
