ABSTRACT The silver halide photographic light-sensitive material comprises a support having thereon a plurality of silver halide emulsion layers of different speed but whose sensitivity is in the same spectral region. The silver halide photographic light-sensitive material also comprises at least one light-sensitive layer comprising a non-diffusible coupler capable of forming non-diff- usible dye by the reaction thereof with an oxidized product of a color developing agent. The silver halide emulsion layer having highest speed among the plurality of silver halide emulsion layers contains a non-diffusible coupler capable of producing a movable dye by the reaction thereof with the oxidized product of a color developing agent. The silver halide emulsion layer having a lower speed than the one among the plurality of silver halide emulsion layers having highest speed contains a non- diffusible compound capable of releasing a development inhibitor material by the reaction thereof with an oxidized product of a color developing agent. This material has improved graininess and excellent sharpness.
