Abstract

1,210,953. Silver halide emulsions. FUJI SHASHIN FILM K. K. Feb. 16, 1968 [Feb. 18, 1967], No. 7832/68. Heading G2C. [Also in Division C2] Silver halide emulsions contain (i) a sensitizing dye of formula (I):- in which Y and Y 1 each complete an optionally substituted benzothiazole, benzoselenazole or quinoline group, R and R, are each aryl, allyl or optionally substituted alkyl, X<SP>-</SP> is an anion and m, n, and n 2 are each 1 or 2, and (ii) an antifoggant/ stabiliser, which may also act as a supersensitizer, of formula (II):- in which R 2- 5 are each halogen, OH, aryloxy, arylthio or arylamino, and A is a 4, 4<SP>1</SP> -(2, 2<SP>1</SP> - disulpho stilbene) or 4, 4<SP>1</SP> -(2, 2<SP>1</SP> - disulpho dibenzyl) or a salt of such a group. Preferably the emulsion contains 0À002-0À2 g. of (i) and 0À02-10 g. of (ii) per mole of silver halide in a ratio of between 1 : 2 and 1 : 200.
