ABSTRACT:
A light-sensitive silver halide photographic material having a support with at least one silver halide emulsion layer containing a dye-forming coupler, where the light-sensitive silver halide photographic material is characterized in that at least one of the silver halide emulsion layers contains (i) the dye-forming coupler dispersed with the use of a high boiling organic solvent having a dielectric constant of 6.0 or less, (ii) silver halide grains containing a gold compound and having silver chloride content of 90 mole % or more, and (iii) a compound represented by General Formula (S) shown below. General Formula (S): ##STR1## where Q is a group of atoms necessary to complete a 5- or 6-membered heterocyclic ring or a 5- or 6-membered ring fused with a benzene ring and M is a hydrogen atom, an alkali metal or an ammonium group.
The light-sensitive material can achieve excellent preservation of the dye image, is feasible for rapid processing, has superior BF contamination resistance and pH variation resistance.
