Abstract: Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) ##STR1## in which: n is the number 0 or 1;Y is the vinyl group or an ethyl group containing, in .beta.-position, a substituent which can be eliminated by means of an alkali;Q.sup.1 and Q.sup.2 both represent a benzotriazole radical which can also be additionally substituted in the benzene nucleus by alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, carboxy or sulfo;B is --O--, --S--, --NH--or --N(R')--wherein R' is optionally substituted alkyl having 1 to 6 carbon atoms;W.sup.1 and W.sup.2 both represent a divalent, optionally substituted aliphatic, cycloaliphatic, aliphatic-cycloaliphatic, araliphatic or aromatic-carbocyclic radical, it being possible for the aliphatic radicals to be interrupted by hetero groups --O--, --S--, --SO.sub.
