<p>Water-soluble triphendioxazine compounds which have valuable fiber-reactive dyestuff properties and correspond to the general formula (1) and dye materials, in particular cellulose fiber materials, containing carboxamide and/or hydroxy groups in fast shades. <IMAGE> (1) in which: B is a group -O-, -S-, -NH- or -N(R')- in which R' is alkyl having 1 to 6 carbon atoms; R* is hydrogen or optionally substituted lower alkyl or optionally substituted aryl; W and W1 independently of one another are each a divalent aliphatic radical or a cycloaliphatic radical which is optionally substituted by lower alkyl or an aliphatic-cycloaliphatic radical which is optionally substituted by lower alkyl, it being possible for the aliphatic radicals to be interrupted by one or more groups -O-, -S-, -SO2-, -CO-, 1,4-piperidino, -NH- and -N(Ro)- in which Ro has the meaning of R' or is lower alkanoyl; the groupings -B-W1-N(R*)- and -N(R*)-W-B 13 independently of one another each represent the divalent radical of a five-membered or six-membered, saturated heterocyclic structure containing two N atoms, or the groupings -B-W1- and -W-B- independently of one another each represent the divalent radical of a five-membered or six-membered, saturated heterocyclic structure which contains two N atoms and which is attached by means of one of the two N atoms, via a C2-C4-alkylene, to the groupings -N(R*)-A or A-N(R*)-, respectively; is benzoyl, naphthoyl, N-phenylcarbamoyl or N-naphthylcarbamoyl in which the phenyl and naphthyl radicals can be substituted, at least one of these being a group which imparts solubility in water; X1 and X2 independently of one another are each hydrogen, halogen, lower alkyl, lower alkoxy or optionally substituted aryl; Y is vinyl or a beta -substituted ethyl; and the compounds necessarily contain at least two sulfo groups.</p> |
