Abstract

1282916 Basic monoazo dyes FARBWERKE HOECHST AG 20 Aug 1969 [20 Aug 1968] 41528/69 Heading C4P Novel basic monoazo dyes, free from sulphonic acid groups of formula wherein A is the residue of a triazolium, imidazolium, pyrazolium or thiazolium ring, Y is a sulphonamide, carboxylic acid amide, COOH, ,carboxylic acid ester group or CN group, D is H or a non-ionic substituent, B is an aromaticcarbocyclic or -heterocyclic radical, Z is OH or a primary, secondary or tertiary amino group and X is an anion are prepared by (a) coupling a diazotized amine of formula with a coupling component H-B-Z or (b) treating a dye of formula with an alkylating agent. The dyes may be used to colour a variety of fibrous materials, in particular polyacrylonitrile fibres in yellow, red and blue shades. Specifications 1,134,175 and 1,169,057 are referred to. Reference has been directed by the Comptroller to Specifications 1,134,175 and 1,169,057.
