Abstract

1408398 Supersensitizing silver halide emulsions FUJI PHOTO FILM CO Ltd 24 Nov 1972 [24 Nov 1971] 54506/72 Heading G2C A silver halide photographic emulsion comprises a supersensitizing combination of at least one dye of Formula I in which A<SP>1</SP> and A<SP>2</SP> each represent H, halogen, OH, alkoxy, optionally substituted amino, acylamido, acyloxy, carbalkoxy, alkoxycarbonylamino, CN, CF 3 , alkoxycarbonyl, alkylsulphonyl, sulphamyl, alkylaminosulphonyl, morpholinosulphonyl, morpholinocarbonyl, piperidinosulphonyl, carbamoyl, alkybarbamoyl, or alkylcarbonyl; A<SP>3</SP> and A<SP>4</SP> each represent H, halogen, alkyl (1-4C) alkoxy, OH, optionally substituted phenyl, carboxyl, alkoxycarbonyl, CN, CF 3 , optionally substituted amino, acyl, acylamido, acyloxy, alkoxycarbonyl, alkoxycarbonylamino or carbalkoxy; R, R<SP>1</SP> and R<SP>2</SP> each represent optionally substituted alkyl, at least one of R<SP>1</SP> and R<SP>2</SP> being a substituted alkyl group comprising a sulpho or carboxy group X<SP>1</SP> is an anion and n is 0 or 1, together with a dye of Formula. in which B<SP>1</SP>, B<SP>2</SP>, B<SP>3</SP> and B<SP>4</SP> each have the same meaning as A<SP>3</SP> and A<SP>4</SP>; R<SP>3</SP> and R<SP>4</SP> each represent optionally substituted alkyl, at least one R<SP>3</SP> and R<SP>4</SP> being a substituted alkyl group comprising a sulpho or carboxy group; R<SP>5</SP> represents H, alkyl or aryl; X<SP>2</SP> is an anion and n is 0 or 1. The dyes sensitize the emulsion to the green region of the spectrum and are resistant to stripping by magenta colour couplers, examples of which are given. The emulsion may also include a water-soluble iodide and/ or a water-soluble bromide. The preferred dyes of Formula I are substituted by a halogen atom in at least one of the 5- or 6-positions of the benzimidazole nucleus and those of Formula II are substituted by a halogen atom at the 5-position of the benzoxazole nucleus.
