Abstract
1392499 Merocyanine dyes ILFORD Ltd 26 July 1973 [26 July 1972] 34929/72 Heading C4P [Also in Division G2] Merocyanine dues for sensitizing silver halide emulsions are of formula (in which R 1 is H or optionally substituted alkyl; R 2-7 are each H, 1-4C alkyl or aryl). In specific dyes R 1 is ethyl, methyl, H or sulphopropyl and R 2-7 are each H, methyl or phenyl. The dyes are prepared by a conventional condensation reaction.
