ABSTRACT:
Water-soluble azo compounds, having fiber-reactive properties and yielding (for instance, on cellulose fiber materials) deep and fast dyeings and prints, of the formula ##STR1## in which D is phenylene which can be substituted by one or two subtituents from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamino, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, chlorine, bromine, fluorine and carboxy and/or by a nitro group and/or by a further group of the formula Y--SO.sub.2 --(CH.sub.2).sub.n -- in which Y has the meaning given below and n here is 1 or 2, or D is naphthylene which can be substituted by one or two substituents from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamine, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, chlorine, bromine, fluorine, carboxy and sulfo and/or by a nitro group, or D is the benzothiazol-2-yl radical which contains the indicated group Y--SO.sub.2 --(CH.sub.2).sub.n -- in the carbocyclic ring and can be further substituted in this benzene nucleus by a substituent from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamino, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, nitro, chlorine, bromine and sulfo, M is hydrogen or an equivalent of a metal, R is the acyl group of an optionally substituted lower alkanoic acid, lower alkenoic acid, aromatic carboxylic acid, lower alkanesulfonic acid, aromatic sulfonic acid, carbamic acid or lower alkenesulfonic acid, Y is the vinyl group or a group --CH.sub.2 --CH.sub.2 --Z in which Z represents a radical which can be eliminated under alkaline conditions, or the hydroxy group, and n is zero, 1 or 2.
