Abstract
1333170 Supersensitized silver halide emulsions ILFORD Ltd 29 March 1972 [19 April 1971] 9814/71 Heading G2C A photographic silver halide emulsion comprises a super-sensitizing combination of a sensitizing dye of the following formula in which R 1 and R 5 are alkyl (1-4C), R 2 and R 3 are H or alkoxy (1-4C), R 6 and R 7 are H, Cl, Br, alkyl (1-4C) or alkoxy (1-4C), R 4 and R 8 are alkyl (1-4C) which may be substituted, e.g. sulphoalkyl, Y is S or Se, X is an anion and P is 1, if an intramolecular salt is formed, or 2, together with a styryl base of the formula in which A represents the atoms necessary to complete a heterocyclic ring e.g. thiazole, benzothiazole, benzoxazole or benzimidazole, and R 9 and R 10 are alkyl (1-4C).
