ABSTRACT:
Disclosed is a silver halide photographic photosensitive material comprising a support and, provided thereon, at least one hydrophilic colloid layer including a photosensitive layer wherein the photosensitive layer comprises monodispersed silver halide grains having an average grain size of 0.2 micron or less and comprising at least 90 mol % of silver chloride, the photosensitive layer or a hydrophilic colloid layer provided on the same side of the support as the side on which the photosensitive layer is provided contains a hydrazine derivative, a hydrophilic colloid layer provided above the photosensitive layer contains a water-dispersible fine particle polymer, the photosensitive layer contains substantially no water-dispersible fine particle polymer, and amount of the water-dispersible fine particle polymer contained in the hydrophilic colloid layer is 1 g/m.sup.2 or less and is 5% by weight or more based on the weight of gelatin contained in the hydrophilic colloid layer.
