Abstract (en)
[origin: EP0572912A2] There is disclosed a silver halide photographic light sensitive material excellent in photosensitive speed and latent image preservability, comprising a silver halide emulsion characterized in that the silver halide grains having one or two development initiating points made present in each of the grains account for not less than 75% of the whole grain of the emulsion. The term, 'development starting point' is recognized as a point at which a development is to be initiated. The points on a grain are preferable to be far away from each other, when two development points are made present in one and single grain. The positions of the development initiating points are also preferable to be on the corner or edge of the grain and the neighborhood thereof. When the grain has twin plane(s), the development initiating positions are preferable to be either on a line formed by exposing the twin plane to the grain surface or in the neighborhood of the line.
