ABSTRACT:
A silver halide multilayer color sensitive material comprising a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer on a support, wherein each silver halide emulsion layer contains a non-diffusible image forming coupler, the improvement which comprises at least one of the silver halide emulsion layers comprising an upper unit silver halide emulsion layer, a middle unit silver halide emulsion layer and a lower unit silver halide emulsion layer, in which the sensitivity of the three unit silver halide emulsion layers decreases in order from the upper unit silver halide emulsion layer to the lower unit silver halide emulsion layer, and at least the middle unit silver halide emulsion layer contains a development inhibitor releasing compound.
