摘要:
A silver halide photographic material is capable of super-rapid processing with the total time of 20 to 60 minutes and is high in sensitivity, low in fogginess and excellent in pressure resistance and graininess. The photographic material is comprises a support bearing a hydrophilic colloial layer including at least one light sensitive silver halide emulsion layer thereon, whereinsilver halide grains contained in the silver halide emulsion layer are mainly comprised of tabular grains which have an aspect ratio of the grain size to the grain thickness of not lower than 5, and the projective areas of the whole tabular grain occupy not less than 50% of the projective areas of the whole silver halide grain in the emulsion layer,the melting time of the silver halide photographic light-sensitive material is within the range of from not shorter than 45 minutes, andon the side bearing the hydrophilic colloidal layer containing the silver halide emulsion layer, an amount of gelatin is within the range of from 2.00 to 3.20 g/m.sup.2.
