Int. Cl. G03c 1/28 U.S. Cl. 96-104 No Drawing. 18 Pages Specification Photographic silver halide emulsions are spectrally sensitized with a dye combination comprising (1) a benzimidazolocarbocyanine dye and (2) a benzimidazoloselenacarbocyanine dye. A preferred dye combination comprises (l) a benzimidazolocarbocyanine dye having the wherein n, m, k and p each represents a positive integer of from 1 to 2; L L and L each represents a methine linkage; R R R and R each represents an alkyl group; R R and R each represents an unsubstituted lower alkyl p; 8, 9, 10 11 12 13 14 and 15 each represents a member selected from the group consisting of a hydrogen atom and a. halogen atom; X and X each represents an acid anion; V represents a member selected from the group consisting of .a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group and an aryl group; and W, Y and Z each represents a member selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an alkoxy group, an acyl group of a monobasic fatty acid, an alkylaminocarbonyl group, a trifiuoroalkyl group and a trifluoroalkylsulfonyl group. A typical example comprises a gelatin silver bromOiOdide emulsion containing the dye combination of 1 anhydro-5,5',6,6-tetrach10ro-1,1-diethyl-3,3-di(3-sulfobutyl)benzimidazolocarbocyanine hydroxide and (2) anhydro 5,6-dichloro-1,3-diethyl-5-methoXy-3'-(3-sulfopropyl)benzimidazoloselenacarbocyanine hydroxide.
