Abstract
1,223,298. Photographic supersensitized silver halide emulsions. ILFORD Ltd. Sept. 16, 1969 [July 3, 1968], No.31709/68. Heading G2C. A photographic silver halide emulsion is supersensitized with a dye of the formula: - where R 1 is alkyl of 1-4C or sulphoalkyl; R 2 is alkyl of 1-4C or alkoxy; R 3 is H or alkyl of 1-4C; R 5 is -SO 3 H or -COOH, Y is S or Se; Z is straight or branched alkylene of 1 -6C and X is an anion, or the corresponding zwitterion formed by eliminating HX, together with a dye of the formula:- where R 4 is alkyl of 1-4C, Z is straight or branched alkylene of 1-6C and M is a cation or a hydrogen ion. A styryl base may also be present of the formula:- where A completes a thiazole ring and R 11 and R 12 are each alkyl of 1-4C. The dyes sensitize to green.
