Abstract

1303498 Basic monoazo dyes FARBWERKE HOECHST AG 28 May 1970 [29 May 1969] 25717/70 Heading C4P The invention comprises basic monoazo dyes, free from SO 3 H groups, of formula wherein R is alkyl or aralkyl which may be substituted, X is an atom or group completing a 5-or 6-membered ring, R 1 and R 2 are H or alkyl or together form a fused aromatic ring, Hal is a halogen atom, Alk is an alkyl group which may be substituted, n is 0 or 1 and A<SP>#</SP> is an anion. The dyes are prepared (a) by coupling a diazotized quaternized heterocylic amine with a 2-halo-N-alkylaniline, (b) alkylating or aralkylating the dyes wherein R is H, or (c) oxidative coupling using a hydrazone of formula wherein B is H or benzenesulphonyl. The dyes are used to colour tannin-treated cellulose, silk, leather or synthetic fibres, in particular acidmodified polyester, polyacrylonitrile or polyvinylidenecyanide fibres in red and blue shades.
