ABSTRACT:
A silver halide light-sensitive material is disclosed. The material is comprised of a support comprising thereon at least two emulsion layers having the same color sensitivity and being different light-sensitivities, with a layer containing comparatively light-insensitive silver halide grains of 0.05 to 0.6 .mu.m in average grain size being positioned in at least one of interspaces defined by every two adjacent members of said at least two emulsion layers. The resulting material has both raised sensitivity and improved graininess.
