ABSTRACT:
A light-sensitive silver halide photographic material suitably applicable to rapid processing with well-restrained fogging, color fading and degradation in the contrast is disclosed. The material comprises a reflective support and, provided thereon, at least one light-sensitive silver halide emulsion layer which contains (1) silver chloride or silver chlorobromide emulsion of which silver chloride content is not less than 90 mole % and said silver chloride or silver chlorobromide emulsion has been prepared by the addition of a heterocyclic mercapto compound or an azaindene compound during the period of formation of silver halide grains contained therein, (2) a dye-forming coupler and (3) a high-boiling organic solvent of which dielectric constant is not more than 6.
