Abstract

Water-soluble triphendioxazine compounds having fiber-reactive dye properties and the general formula (1) ##STR1## in which the meanings are: T is a substituted or unsubstituted alkyl of 1 to 6 carbon atoms, except an ethyl which is substituted in the .beta.-position by an alkalinically eliminatable substituent, which alkyl can be interrupted by --O--, --S--, --NH-- and --N(R')-- where R' is equal to substituted or unsubstituted alkyl of 1 to 6 carbon atoms, or is substituted or unsubstituted aryl, B is --O--, --S--, --NH-- or --N(R')-- where R' is equal to substituted or unsubstituted alkyl, W is a bridge member or W and B together form a direct bond, R is hydrogen or a substituent, R* is hydrogen or a substituent or R* and W, if W contains an amino group, or a portion of W form together with the nitrogen atoms the radical of a heterocycle, A is a non-heterocyclic fiber-reactive group or a 2-halogeno-s-triazin-6-yl radical which is substituted in the 4-position by halogen or a substituted or unsubstituted amino group which can also contain a fiber-reactive group, or by a heterocyclic radical or by a further such halogenotriazinyl radical bonded via an amino radical as bridge member, X.sup.1 and X.sup.2 are each hydrogen, halogen, cycloalkyl, aralkoxy, alkoxy, aryloxy, alkyl, aryl, aralkyl, cyano, carboxy, carbalkoxy, arylamino, carbamoyl and alkylmono- or -disubstituted carbamoyl or arylcarbamoyl, alkanoylamino or aroylamino, which aryl radicals can in each case be substituted; of the sulfo and sulfate groups the molecule mandatorily contains at least one of these groups, furthermore precursors of the formulae ##STR2## with B* equal to --NH-- or --N(R')-- and R, R*, W and T of the abovementioned meanings. The triphendioxazine compounds serve for dyeing chiefly wool and synthetic polyamide fibers and in particular cellulose fibers by means of application and fixing methods which are customary for fiber-reactive dyes.
