ABSTRACT:
Triphendioxazine compounds corresponding to the formula (1) ##STR1## in which Z is a radical of the formula (2) ##STR2## in which Y.sup.1 and Y.sup.2 each vinyl .beta.-hydroxyethyl or an ethyl radical which contains a substituent which can be eliminated under alkaline conditions in the .beta.-position, and in which Y.sup.1 and Y.sup.2 are not simultaneously .beta.-hydroxyethyl, W.sup.1 and W.sup.2 are both allyene having 2 to 6 carbon atoms, A is a covalent bond of a group of the formula --B.sup.1 --N(R.sup.3)--, in which R.sup.3 has one of the meanings of R.sup.1 and B.sup.1 is an aliphatic or aromatic bridge member, and in which the group--N(R.sup.1) --B.sup.1 --N(R.sup.3)-- can also be in total a bivalent saturated heterocyclic radical, and Z.sup.0 is hydrogen or a group of the formula (4) ##STR3## in which A.sup.0 is a covalent bond or a radical or the formula --N(R.sup.4)--B.sup.2 -- having the meaning corresponding to the above formula --B.sup.1 (NR.sup.3)-- are described. The triphendioxazine compounds of the formula (1) are used as fiber-reactive dyestuffs for dyeing material containing hydroxy, amino and/or carboxamide groups.
