Abstract

1344281 Super sensitized photographic silver halide emulsions FUJI PHOTO FILM CO Ltd 3 May 1971 [1 May 1970] 12772/71 Heading G2C A silver halide photographic emulsion contains at least one sensitizing dye of the formula:- wherein R 1 , R 2 and R 3 are each alkyl or substituted alkyl, at least one of R 1 , R 2 and R 3 being substituted with a sulpho group to form a betaine type structure; R 4 is H or forms an alkylene linkage together with R 2 ; Z 1 completes a benzimidazole nucleus which may be substituted; A 1 and A 2 are each H 1 halogen, phenyl, carboxyl, alkoxycarbony, alkyl, alkoxyl, hydroxyl, trifluoromethyl or cyano, or A 2 may be condensed with A 1 or A 3 to form a benzene nucleus; A 3 is H or alkyl if not condensed withA 2 , at least one of A 1 , A 2 or A 3 being substituent other than H when R 2 and R 4 are bridged by an alkylene group and Z 1 is substituted by at least two halogen atoms, in supersensitizing combination with at least one sensitizing dye of the formula:- wherein R 5 , R 6 , R 7 and R 8 have the same meanings as R 1 , R 2 or R 3 , at least one of R 5 , R 6 , R 7 and R 8 being substituted alkyl group having a sulpho or carboxyl substituent; Z 2 and Z 3 each complete a substituted or unsubstituted benzimidazole nucleus; X‹ is an anion; and n is 1 or 2, n being 1 when an intramolecular salt is formed. Many examples of these sensitizing dyes are given. The spectral sensitivity of the emulsion at 500-530 nm is increased while holding the maximum sensitizing wavelength over 540 to 570 mm within the wavelength range of 490-590 nm (green region) and the reduction in sensitivity due to the presence of a colour coupler is low. Staining due to residual dyes left after development is reduced. Reference has been directed by the Comptroller to Specification 852915.
