Abstract

1350669 Monoazo dyes FARBWERKE HOECHST AG 9 July 1971 [11 July 1970] 32366/71 Heading C4P New water-soluble monoazo dyes of formulae wherein Z is H, aliphatic or aromatic carboxylic acid acylamino or sulphonamido, n is 1 or 2, two of the X symbols represent H and the other the vinylsulphonyl, 2-hydroxyethylsulphonyl or an ethylsulphonyl group substituted in the 2- position by a radical capable of being split off by an alkaline agent are prepared by coupling a diazotized 2-naphthylamine with an appropriate 1-naphthol-sulphonic acid. The dyes may be used to colour natural and synthetic polyamide, polyurethane and, in particular, cellulose fibres by the usual reactive dyeing processes, in orange and red shades. In Examples dyes of the above formulae wherein the radical which can be split off by alkali is trimethylammonium, sulphate, phosphate, thiosulphate, chloro and dimethyl-amino, are described.
