Abstract

Triphendioxazine compounds, which are suitable as fiber-reactive dyestuffs, of the general formula (1) ##STR1## in which R.sup.1 and R.sup.2 are each a hydrogen atom, an optionally substituted alkyl group with 1 to 8 carbon atoms, the substituents being, for example, sulfo, sulfato, carboxy and optionally substituted alkylamino and dialkylamino groups, or a cycloalkyl group which can optionally be substituted by methyl and/or amino, alkanoylamino or benzoylamino, or an optionally substituted phenyl radical, the substituents of which are, for example, sulfo, carboxy, halogen, alkyl with 1 to 4 carbon atoms, alkoxy with 1 to 4 carbon atoms, nitro and .beta.-sulfatoethylsulfonyl, or a naphthyl radical which can be substituted by 1, 2 or 3 sulfo groups and/or a fiber-reactive group of the vinylsulfone series, or in which R.sup.1 and R.sup.2, together with the nitrogen atom, can form a heterocyclic radical, and in which the benzene nuclei A can be substituted by 1 or 2 substituents from the group comprising alkyl with 1 to 6 carbon atoms, alkoxy with 1 to 5 carbon atoms, halogen, carboxyl and sulfo, the two radicals X.sup.1 and X.sup.2 are identical to one another or different from one …
