ABSTRACT:
A silver halide photographic emulsion containing a supersensitizing amount of the combination of at least one dye represented by the general formula (I) ##SPC1##
wherein Z represents the non-metal atoms necessary to form a benzene nucleus; R.sub.0, R.sub.1 and R.sub.2 each represents aliphatic groups, with at least one of R.sub.1 and R.sub.2 representing an alkyl group containing a carboxy group or an alkyl group containing a sulfo group; Y represents a halogen atom; X represents an acid anion; n represents an integer of 1 to 2, with n being 1 when the dye forms an intramolecular salt; and at least one dye represented by the general formula (II) ##EQU1## wherein Z.sub.1 represents the non-metal atoms necessary to form a 5-or 6-membered heterocyclic nucleus; Q represents the atoms necessary to form a rhodanine nucleus, a 2-thio-2,4-imidazolidinedione nucleus, a 2-pyrazoline-5-one nucleus, or a 2-thio-2,4-oxazolidinedione nucleus; R.sub.3 represents an aliphatic group; R.sub.4 represents a hydrogen atom, an alkyl group, an alkoxy group, or a mono-aryl group; m represents 1 or 2; and p represents 1 or 2.
