Abstract
1310994 Supersensitized photographic silver halide emulsions ILFORD Ltd 2 Aug 1971 [12 Aug 1970] 38894/70 Addition to 1230449 Heading G2C A photographic silver halide emulsion is supersensitized in the green region with a dye of the formula where each of R 6 and R 7 is H or CH 3 , R 9 is alkyl of 1-4C, R 8 is -COOH or -SO 3 H, Z is a straight or branched alkylene chain containing up to 6C and X is an anion, or the corresponding zwitterion formed by elimination of X and the hydrogen of -SO 3 H, together with a styryl base of the formula where B completes a thiazole, benzothiazole, benzimidazole, oxazole or benzoxazole ring which may be substituted and R4 and R5 are each alkyl of 1-4C.
