Abstract
A silver halide photographic light-sensitive material is described, comprising a support and at least one silver halide emulsion layer on the support, wherein the silver halide emulsion layer contains at least one specific type of sensitizing dye, at least one of the silver halide emulsion layer and other hydrophilic colloid layers contains at least one compound of four specific types of compounds and the silver halide grains contained in the silver halide emulsion are substantially tetradecahedral grains in which the proportion of (100) faces is at least 50%; this material is superior in both sensitivity and stain resistance.
