Abstract
1,216,203. Photographic supersensitized silver halide emulsions. FUJI SHASHIN FILM K.K. July 18, 1968 [July 26, 1967], No.34374/68. Heading G2C. [Also in Division C4] A photographic silver halide emulsion containing a supersensitizing combination of at least one carbocyanine dye represented by the general formula (I):- wherein Z 1 represents a group of atoms necessary for forming a naphthothiazole ring or a naphthoselenazole ring which may be substituted; Z 2 represents a group of atoms necessary for forming a napthothiazole ring, a napthoselenazole ring, a benzothiazole ring, or a benzoselenazole ring which may be substituted; R 1 and R 2 each represents an alkyl group or a substituted alkyl group; A represents a phenyl group or a substituted phenyl group; X 1 <SP>-</SP> represents an anion; and n is 0 or 1, said dye forming an intramolecular salt when n is 0; and at least one carbocyanine dye represented by the general formula (II):- wherein Z 3 and Z 4 each represents a group of atoms necessary for forming a benzothiazole ring or a benzoselenazole ring which may be substituted; R 3 and R 4 each represents an alkyl group or a substituted alkyl group; R 5 represents a lower alkyl group having 1 to 4 carbon atoms; X<SP>-</SP> 2 represents an anion; and m is 0 or 1, said dye forming an intramolecular salt when m is 0. The spectral sensitivity of the red-sensitive region is increased in the photographic silver halide emulsion of this invention.
