Abstract

Water-soluble monoazo compounds of the formula ##STR1## are described, suitable as fiber-reactive dyes for dyeing hydroxy- and/or carboxamido-containing material, in particular fiber material, such as wool and cellulose fiber materials, in which D is phenylene which can be substituted by 1 or 2 substituents customary in diazo components of fiber-reactive dyes and/or by a group of the formula Y--SO.sub.2 --(CH.sub.2).sub.m -- where Y has one of the meanings given below and m is the number 1 or 2, or is naphthylene which can be substituted by 1 or 2 substituents customary in diazo components of fiber-reactive dyes, or is benzothiazol-2-yl containing the group aforementioned Y--SO.sub.2 --(CH.sub.2).sub.n -- bonded to the carbocyclic ring thereof and can be substituted by a further substituent customary in fiber-reactive dyes, n is the number zero, 1 or 2, the group Y-SO.sub.2 -- is a fiber-reactive group from the vinylsulfonyl series, M is hydrogen or the mole equivalent of a metal, such as, in particular, an alkali metal, and the group --NR.sup.1 R.sup. 2 represents an amino group optionally substituted by lower alkyl and/or phenyl, which lower alkyl and phenyl may be substituted by substituents customary for fiber-reactive dyes.

A compound of the formula ( 1) ##STR7## in which Y is vinyl, or is ethyl which contains a substituent in the .beta. position which is eliminated by an alkali with the formation of a vinyl group, or is .beta.-hydroxyethyl;

n is the number zero, 1, or 2;
D is phenylene which is unsubstituted or is substituted by 1 or 2 of the following substituents:
alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, sulfo, chlorine, bromine, fluorine, carboxy, nitro, hydroxy, alkanoylamino of 2 to 5 carbon atoms, benzoylamino or benzoylamino which is substituted by a substituent selected from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine and sulfo, or by 1 or 2 of these substituents and a group of the formula Y--SO.sub.2 --(CH.sub.2).sub.m -- in which Y is as defined previously and m is the number 1 or 2, or by a group of the formula
Y--SO.sub.2--(CH.sub.2).sub.m --,
M is hydrogen or the mole equivalent of a metal;
R.sup.1 is hydrogen or alkyl of 1 to 4 carbon atoms, or is phenyl, or is alkyl of 1 to 4 carbon atoms which is substituted by 1 or 2 substituents selected from the group consisting of hydroxy, alkanoyloxy of 2 to 5 carbon atoms, sulfato, phosphato, phosphono, sulfo, carboxy, the phosphonic acid group, alkoxy of 1 to 4 carbon atoms, phenyl, sulfophenyl and cyano;
R.sup.2 is alkyl of 1 to 4 carbon atoms, or is phenyl, or is alkyl of 1 to 4 carbon atoms which is substituted by 1 or 2 substituents selected from the group consisting of hydroxy, alkanoyloxy of 2 to 5 carbon atoms, sulfato, phosphato, phosphono, sulfo, carboxy, the phosphonic acid group, alkoxy of 1 to 4 carbon atoms, phenyl, sulfophenyl and cyano, or is phenyl which is substituted by 1,2 or 3 substituents selected from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine, cyano, nitro, sulfo, carboxy and carbamoyl, or is naphthyl or naphthyl which is substituted by 1, 2 or 3 sulfo groups or 1 or 2 carboxy groups or by 1 or 2 sulfo groups and a carboxy group.
