Abstract
Water-soluble monoazo and disazo compounds which have fiber-reactive dyestuff properties and containing as diazo component an optionally substituted phenyl radical or naphthyl radical or an optionally substituted phenylazophenyl, phenylazonaphthyl, naphthylazophenyl or naphthylazonaphthyl radical, and as coupling component that of a naphthol, aminonaphthaline or aminobenzene and as fiber-reactive group a group of the formula ##STR1## in which both R.sup.1 s, identical to or different from one another, denote a hydrogen atom or an optionally substituted alkyl group of 1 to 4 carbon atoms, R is a hydrogen atom or a sulfo group and Y represents a vinyl group or a .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-chloroethyl or .beta.-sulfatoethyl group, this fiber-reactive grouping being bonded to the radical of the coupling component. These azo compounds have fibre-reactive dyestuff properties and are suitable for dyeing carboxamide and/or hydroxy-containing materials, such as wool and synthetic polyamide fibers, in particular cellulose fibres, in deep and fast shades, when applied according to the usual methods of application and fixation, suitable for fibre-reactive dyestuffs.
