ABSTRACT:
A silver halide photographic emulsion containing a combination of at least one merocyanine dye free of acidic groups and a benzotriazole compound which can produce a slightly soluble silver salt by reaction with silver ion, where the solubility product of the resulting silver salt is smaller than that of silver chloride, in effective supersensitizing amounts which exhibits reduced fog and a markedly increased spectral sensitivity.
