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, PA0 B is --O--, --S--, --NH-- or --N(R")-- where R" is equal to substituted or unsubstituted alkyl, PA0 W is a bridge member or PA0 W and B together form a direct bond, PA0 R is hydrogen or a substituent, PA0 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, PA0 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…
