Abstract
A silver halide photographic light-sensitive material suitable for rapid processing is disclosed which is prevented in fogging and improved in raw stock storage stability. The photographic material comprises photographic component layers including a silver halide emulsion layer, and the silver halide emulsion layer contains silver halide grains having a silver chloride content of not less than 90 mol %, and at least one of the photographic component layers contain a nitrogen-containing heterocyclic compound capable of forming a compound with silver ion having a solubility product of not more than 1.times.10.sup.-10 and a sulfur- containing compound selected from the group consisting of organic compounds having a polysulfer linkage comprised of three or more sulfer atoms, and organic compounds having a heterocyclic ring having at least two thioether linkages or at least one disulfer linkage.
