Abstract

Water-soluble azo compounds, preparation thereof and use thereof as dyes There are described monoazo compounds conforming to the formula (1) ##STR1## which are used as dyes having fiber-reactive properties for preparing strong, red, fast dyeings and prints on hydroxy- and/or carboxamido-containing material, in particular fiber material, such as wool and synthetic polyamide fibers and in particular cellulose fibers, such as cotton. In the formula (1): M is hydrogen or an alkali metal; R.sup.1 is hydrogen or sulfo; R.sup.2 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, sulfo, hydroxy, halogen or carboxy; R.sup.3 is hydrogen, halogen, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms; Y is vinyl or is ethyl which contains in the .beta.-position a substituent which is eliminable with alkali to form a vinyl group; p is 1 or 2; the one --SO.sub.3 M group is attached to the naphthalene ring para or meta to the amino group.
