Abstract

1,211,735. Super-sensitized photographic silver halide emulsions. FUJI SHASHIN FILM K.K. Dec.4, 1967 [Dec.3, 1966], No.55150/67. Heading G2C. [Also in Divisions C2 and C4] A photographic silver halide emulsion is supersensitized by a mess-substituted dicarbocyanine dye of the formula:- where Y and Y 1 each complete a heterocyclic ring, R and R 1 are each alkyl which may be substituted, aryl, allyl or aralkyl, R 2 is halogen or alkyl, X is an anion and n and m are each 1 or 2, together with a compound of the formula:- where Z is -CH= or -N=, R 3 and R 4 are each halogen, hydroxyl, alkoxyl, aryloxyl, arylthio, aryl, amino, alkylamino, arylamino or aralkylamino and A is m or p-phenylene, 1:5-naphthylene, 4:4<SP>1</SP>-diphenylene, 4:4<SP>1</SP>-diphenylene ether, 4:4<SP>1</SP>- diphenylene methane or a radical of the formula:- where M is hydrogen, alkali metal, ammonium or an amine salt group.
