Abstract
1355853 Silver halide emulsions FUJI PHOTO FILM CO Ltd 23 Sept 1971 [24 Sept 1970] 44520/71 Heading G2C [Also in Division C4] Photographic silver halide emulsions contain a supersensitizing combination of (A) at least one carbocyanine dye which has a sensitizing maximum from 600-660 nm. when the same amount of dye is used alone in the emulsion and in which each heterocyclic nucleus is benzothiazole or benzoselenazole at least one of which is substituted by 5-acetylamino, and (B) at least one dye of formula (in which R 3 and R 4 are each 1-8C alkyl which may be substituted by a sulpho-, carboxy- or hydroxygroup; A, is aryl or 1-4C alkyl; Z 3 and Z 4 each complete a benzothiazole, benzoselenazole or #-naphthothiazole nucleus; X 2 is anion; m is 0 or 1). Preferably (A) is of formula (in which R 1 and R 2 are each allyl, or 1-8C alkyl which may be substituted by a sulpho-group A 1 is 1-4C alkyl; Z 1 completes a benzothiazole or benzoselenazole nucleus; Z 2 is S or Se; X 1 is anion; n is 0 or 1). The emulsion may also contain a green-sensitizing dye, especially a 2, 21-cyanine or thia-2<SP>1</SP>-cyanine and two dyes of formula (I).
