Abstract

1,257,652. Azamethine dyes. YORKSHIRE CHEMICALS Ltd. 14 Feb., 1969 [9 April, 1968], No. 16912/68. Heading C4P. Water-soluble dyes for dyeing polyacrylonitrile fibres are of formula (in which R 1 , R 2 and R 5-8 are alkyl, R 3 is alkyl or cycloalkyl, or R 1-3 together complete a heterocyclic ring, and X is an anion; the alkyl and cycloalkyl groups and/or rings A and B may be substituted). The dyes are prepared by alkylating a dye of the above formula in which R 5 is H; these latter dyes are prepared by coupling equimolar amounts of a diazotized aminoanilide and a 2-methylene indoline, followed by treatment with an alkali.
