ABSTRACT:
A light-sensitive silver halide emulsion is disclosed, which comprises light-sensitive silver halide grains in a binder, wherein tabular grains having a diameter of at least 0.15 .mu.m account for at least 70% of the total projected area of said silver halide grains, said tubular grains have a mean aspect ratio of not more than 8.0, and at least 50% (by number) of all of said tabular grains are tabular grains in which the ratio (b/a) of the thickness (b) of said tabular grain to the longest spacing (a) between two or more parallel twinning planes of said tabular grain is at least 5. A color photographic material using the light-sensitive silver halide emulsion for at least one of the silver halide emulsion layers other than the outermost silver halide emulsion layer is also disclosed.
