Abstract
There is disclosed a silver halide photographic light-sensitive material which comprises a support, a combination of an unfogged surface latent image type silver halide photographic emulsion and a material which is non-diffusible under alkali conditions and which is capable of releasing a diffusible development inhibitor or a precursor thereof as a result of cross oxidation with an oxidized product of a photographic developing agent; and a combination of an internal latent image type silver halide photographic emulsion whose silver halide grains contain therein, prior to development, fog nuclei and a dye image-forming material which is initially non-diffusible under alkaline conditions but which is capable of releasing a diffusible dye or a precursor thereof as a result of being oxidized by the oxidized product of said photographic developing agent.
