Silver halide color photosensitive material
摘要:
A silver halide color photosensitive material comprising a support and, superimposed thereon, at least one blue-sensitive silver halide emulsion layer, green-sensitive silver halide emulsion layer and red-sensitive silver halide emulsion layer, wherein (i) the specified speed of the photosensitive material is 350 or higher, (ii) the coating amount of silver in the photosensitive material is 7 g/m2 or less, and (iii) any of the color-sensitive silver halide emulsion layers is composed of two or more silver halide emulsion layers of different photographic speeds, of which the silver halide emulsion layer with the highest photographic speed contains tabular silver halide grains of 8 or greater aspect ratio in a ratio of 70% or more based on the total projected area and regular-crystal silver halide grains of 0.1 to 0.5 μm equivalent sphere diameter in a ratio of 0.5 to 5% based on the total projected area.
