Abstract

1,128,840. Supersensitized emulsions. FUJI SHASHIN FILM, K. K. Nov. 7, 1966 [Nov. 6, 1965], No. 49845/66. Heading G2C. A photographic silver halide emulsion contains at least one optical sensitiser of the formula:- and at least one optical sensitiser of the formula II) wherein R1, R2, R3 and R4 each represents an alkyl group (substituted or unsubstituted), at least one of said groups R1, R2, R3 and R4 being an alkyl group (substituted or unsubstituted) containing a carboxyl group or a sulpho group or a sulpho or carboxyl anion; V represents a halogen atom; X represents an anion; and n is 2 except in the case when R1 and R3 contain a sulpho or carboxyl anion when n is 1. The alkyl groups may be substituted by vinyl, ether, aryl, sulphate, acetoxy or hydroxy groups.
