    摘要: A silver halide photographic emulsion which is spectrally sensitized so that it has a maximum sensitivity wave length within the region of 580-640 nm, characterized by containing in a super sensitizing amount the combination of at least one carbocyanine dye represented by the general formula (I) and at least one of the dyes selected from the group consisting of dyes represented by the general formula (II): ##EQU1## WHEREIN Z.sub.1 represents the grouping necessary for the formation of .beta.-naphthothiazole or .beta.-naphthoselenazole ring, Z.sub.2 represents the grouping necessary for the formation of benzoxazole ring, A.sub.1 represents a hydrogen atom, an alkyl radical or an aryl radical, R.sub.1 represents an alkyl group and R.sub.2 represents a hydroxyalkyl group, a carboxyalkyl group or an alkyl group substituted with a sulfo group, X.sub.1 represents an acid anion group, an l is 1 or 2, the dye forming an intramolecular salt when l is 1: ##EQU2## WHEREIN Z.sub.3 and Z.sub.4 each represents the grouping necessary for the formation of a benzothiazole, benzoselenazole, .beta.-naphthothiazole or .beta.-naphthoselenazole ring, A.sub.2 represents a hydrogen atom, an alkyl radical having less than three carbon atoms or an aryl radical, R.sub.3 and R.sub.4 each represents an alkyl radical, at least one of which represents a hydroxyalkyl radical, a carboxyalkyl radical or an alkyl radical having a sulfo group, X.sub.2 represents an acid anion group, and m is 1 or 2, the dye forming an intramolecular salt when m is 1.
