Abstract
Water-soluble monoazo and disazo compounds having fiber-reactive dye properties which are suitable for dyeing carboxamido and/or hydroxy-containing materials, in particular cellulose fiber materials, and contain as coupling component that of a naphthol, aminonaphthalene or aminobenzene and as diazo component an optionally chlorine-, alkyl-, alkoxy- and/or sulfo-substituted phenyl radical or an optionally substituted phenylazophenyl or phenylazonaphthyl radical having the fiber-reactive group of the general formula ##STR1## in which the two R.sup.1, identical to or different from each other, 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 the vinyl group or a .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-chloroethyl or .beta.-sulfatoethyl group, as substituent, and a further such fiber-reactive grouping can be bonded to the radical of the coupling component.
