Abstract

Abstract A light-sensitive silver halide photographic material is described comprising a support and, provided thereon, at least one light-sensitive silver halide emulsion layer which comprises; silver halide grains containing a gold compound and having a silver chloride content of at least 90 mole %, a dye-forming coupler dispersed therein using a high boiling-point organic solvent having a dielectric constant of not more than 6.0, and a compound of formula [S]; wherein Q is a group which, together with the carbon and nitrogen to which it is attached, completes a 5- or 6-membered heterocyclic ring or a 5- or 6-membered ring fused with a benzene ring and M is hydrogen, an alkali metal or ammonium.
