Abstract

1427347 Monoazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 25 July 1973 [10 Aug 1972] 37353/72 Heading C4P New azo dyes, free of SO 3 H groups, of formula wherein the naphthalene nucleus may be further substituted, A is an aromatic carbocyclic or heterocyclic radical which may be substituted each of R<SP>1</SP> and R<SP>2</SP> being alkyl, aralkyl, cycloalkyl or aralkyl which may be substituted and the COOH group is directly attached to a carbon atom of a ring in A or the naphthalene ring, are prepared by azo coupling. The dyes are used to colour cellulose ester, synthetic polyamide, polyacrylonitrile, polyurethane and, in particular, polyester fibres and blends thereof with wool or cotton in red and blue shades.
