| 摘要 |
Water-soluble monoazo compounds of the formula <IMAGE> (1) 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-SO2-(CH2)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-SO2-(CH2)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-SO2- 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 -NR1R2 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.
