Abstract

1434418 Water-soluble reactive monoazo dyes HOECHST AG 20 July 1973 [22 July 1972] 34662/73 Heading C4P A water-soluble, reactive, monoazo dyestuff has the formula in which R represents C 1-4 alkoxy, C 1-4 alkyl or halogen, R<SP>1</SP> is H, C 1-4 alkoxy, C 1-4 alkyl or halogen, X represents the #-hydroxyethylsulphonyl gp., the vinylsulphonyl gp., or an ethylsulphonyl gp. substd. in #-position by an organic or inorganic radical capable of being split by an alkaline agent, and A represents the radical of a 1- or 2-naphthylamine mono-, di- or trisulphonic acid. The dyes are prepared by diazotization and coupling, or by condensation reactions to modify the group X. Typical end groups exemplified are: vinyl, -OH, -OSO 3 H, -S-SO 3 H, -OPO 3 H 2 , -NR 2 , -Cl and -Br. The dyes are suitable for dyeing and printing fibre materials containing nitrogen, e.g. wool, silk, leather, polyurethane and polyamide fibres, and especially regenerated or natural cellulose fibres such as cotton, spun rayon, viscose rayon and linen, in reddish-yellow to orange hues.
