Abstract
1,181,020. Green-sensitive silver halide emulsions. ILFORD Ltd. July 3, 1968 [July 4, 1967], No.30778/67. Heading G2C. A green sensitive gelatino silver halide photographic emulsion comprises, substantive thereto, at least one magenta yielding colour former and in sensitizing amount a cyanine dye of the general formula wherein R 1 represents a halogen atom or a lower alkyl or amino group, R and R 3 are the same or different and represent lower alkyl groups containing at least two carbon atoms, one of R 2 and R 4 is a sulphoalkyl group of the formula -(CH 2 ) n SO 3 H where n is an integer from 1 to 6, and the other of R 2 and R 4 is the same or different said sulphoalkyl group or is an alkyl, hydroxyalkyl, aralkyl, carboxy-substituted aralkyl, or carboxy-substituted alkyl group, an acylsulphamoyl alkyl group of the formula -(CH 2 ) n SO 2 NHCOR 8 , or an alkyl or aralkyl sulphamoyl alkyl group of the formula -(CH 2 ) n SO 2 NHR 9 where n in the last two formulae is an integer from 1 to 6, R 8 is an alkyl group and R 9 is an alkyl or an aralkyl, R 5 represents a hydrogen or halogen atom or an alkyl or amino group, R 6 represents a hydrogen or halogen atom or a trifluoromethyl, cyano or alkoxycarbonyl group, and X is an anion.
