Abstract
Abstract A silver halide light-sensitive material is described, comprising (1) an emulsion layer containing light-sensitive silver halide grains, and (2) a layer containing metal salt grains on which a dye is adsorbed, which cannot be substantially developed and are sparingly soluble in water, wherein the absorption maximum of said dye is separated by 20 nm or more from the sensitization maximum of an emulsion layer located in a position farther from the light source than the layer containing said dye.
