Abstract (en)
[origin: EP0560036A2] Disclosed is a silver halide photographic light-sensitive emulsion comprising grains having twin planes, wherein at least 60 % of projected area of the whole grains are occupied by said grains having twin planes, and part or all of said grains having twin planes each have a start point of development at a cross point or the vicinity of said cross point, wherein said cross point is formed by a line formed by a twin plane border lying bare to the grain surface, which intersects an ridge line of the grain. The silver halide photographic emulsion has a high sensitivity, high color forming performance, promising a good processing stability and good pressure resistance. <IMAGE>
