ABSTRACT:
A spectrally sensitized silver halide photographic emulsion containing, in combination, supersensitizing amounts of at least one sensitizing dye represented by the following general formula (I): ##STR1## wherein Z.sup.1 and Z.sup.2 each represents an atomic group necessary for completing a benzimidazole nucleus, an oxazole nucleus, a benzoxazole nucleus, a naphthoxazole nucleus, a thiazole nucleus, a benzothiazole nucleus, a naphthothiazole nucleus, a selenazole nucleus, a benzoselenazole nucleus or a naphthoselenazole nucleus excepting that both of Z.sup.1 and Z.sup.2 do not simultaneously represent an atomic group necessary for completing an oxazole nucleus, a benzoxazole nucleus or a naphthoxazole nucleus; R.sup.1 and R.sup.2 each represents an aliphatic group which may be substituted and the carbon chain of which may be interrupted with an oxygen atom or a sulfur atom; R.sup.0 represents a hydrogen atom, an alkyl group or an aralkyl group; X.sub.(1).sup.- represents an anion; and m is 1 or 2, with m being 1 when the dye forms an intramolecular salt; and at least one sensitizing dye represented by the following general formula (II): ##STR2## wherein Z.sup.3 and Z.sup.4 each represents an atomic group necessary for completing a pyrroline nucleus, a pyridine nucleus, an indolenine nucleus, a benzimidazole nucleus, an oxazole nucleus, a benzoxazole nucleus, a naphthoxazole nucleus, a thiazoline nucleus, a thiazole nucleus, a benzothiazole nucleus, a naphthothiazole nucleus, a selenazole nucleus, a benzoselenazole nucleus, or a naphthoselenazole nucleus; R.sup.3 and R.sup.4 each represents an aliphatic group which may be substituted and the carbon chain of which may be interrupted with an oxygen atom or a sulfur atom, and at least one of R.sup.3 and R.sup.4 represents an aliphatic group containing a hydroxy group, a carboxy group or a sulfo group; X.sub.(2).sup.- represents an anion; and n is 1 or 2, with n being 1 when the dye forms an intramolecular salt.
