ABSTRACT:
A silver halide photographic material containing a support having provided thereon blue-sensitive, green-sensitive, and red-sensitive layers, in which at least the blue-sensitive layer is composed of at least two layers including a more sensitive layer and a less sensitive layer. The most sensitive layer of the blue-sensitive layer is a blue-sensitive layer containing an emulsion of substantially monodispersed grains, and at least one layer other than the most sensitive layer contains an emulsion containing tabular silver halide grains of about 5:1 or more in average aspect ratio. The material has superior sharpness and graininess, and is useful for color photography.
