Silver halide photographic light sensitive material having different sized silver halide emulsions in the same layer

Abstract

A photographic light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer is disclosed, which contains in said silver halide emulsion layer two silver halide emulsions which are different from each other in mean grain size and which satisfy the conditions that: one of the silver halide emulsions, having a relatively larger mean grain size, has a mean grain size (X.sub.1) of 1.3 .mu.m or more; the mean grain size (X.sub.2) of the other silver halide emulsion, having a relatively smaller mean grain size, and X.sub.1 has a relation satisfying Formula (1) Formula (1): 0.5.ltoreq.X.sub.2 /X.sub.1 .ltoreq.0.9; the ratio of the standard deviation (S.sub.1) of the grain sizes of the silver halide emulsion having a relatively larger mean grain size to X.sub.1 satisfies the Formula (2) Formula (2): S.sub.1 /X.sub.1 .ltoreq.0.25; the ratio of the standard deviation (S.sub.2) of the grain sizes of the silver halide emulsion having a relatively smaller mean grain size to X.sub.2 satisfies Formula (3) Formula (3): 0.2<S.sub.2 /X.sub.2 ; and the two ratios of standard deviation of grain sizes of silver halide emulsion to mean grain size satisfy Formula (4) Formula (4): S.sub.1 /X.sub.1 <S.sub.2 /X.sub.2.
