ABSTRACT:
Disclosed are a silver halide grain comprising 8 or 12 concavities on the surface, and a photographical light-sensitive material containing a silver halide grain having 8 to 12 concavities on the surface.
According to the present invention, there can be obtained silver halide grains having still higher sensitivity and also improved in the relationship of sensitivity-fog as compared with those of the prior art, and also a light-sensitive silver halide material by use of an emulsion containing said grains.
