Abstract
Compounds of the formula ##STR1## in which the variables are as defined in the claims, which are suitable as fibre-reactive dyes for dyeing widely varying fibre materials, are described.
Claims5
A compound of the formula ##STR80## in which R is substituted or unsubstituted C.sub.1 -C.sub.4 alkyl,
- R.sub.1 is hydrogen,
- X is halogen,
- Z is a radical of the formula ##STR81## in which T' is a non-reactive amino radical, X" is independently as defined above for X and
- (R.sub.4).sub.1-2 is 1 or 2 identical or different radicals R.sub.4 from the group consisting of methyl, methoxy, sulfo, and reactive radicals of the formulae
- --SO.sub.2 --Y (2a),
- --CONH--(CH.sub.2).sub.n --SO.sub.2 --Y (2b),
- --NH--CO--Y.sub.1 ( 2d),
- in which
- Y is vinyl, .beta.-chloroethyl, .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-acetoxyethyl, .beta.-phenoxyethyl or .beta.-phosphatoethyl,
- Y.sub.1 is a group --CHX.sub.1 --CH.sub.2 X.sub.1 or --CX.sub.1 .dbd.CH.sub.2 and X.sub.1 is bromine or chlorine, and
- n is an integer from 1 to 6;
- and
- D is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan or dioxazine chromophore,
- with the provisos that (i) at least one of the radicals D and Z carries a fibre-reactive radical --SO.sub.2 --Y or --NHCO--Y.sub.1, in which Y and Y.sub.1 are as defined above, and
- that (ii) the radical --NR.sub.1 -- is not bonded to a phenylene radical substituted by --NH.sub.2 if D is the radical of a monoazo or disazo chromophore.
