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 another and are a hydrogen atom, a halogen atom, a cycloalkyl group, an aralkoxy group, an alkoxy group, an aryloxy group, an alkyl group, an aryl group, an aralkyl group or a cyano, carboxy, carbalkoxy, mono- or di-alkylcarbamoyl, arylarylcarbamoyl, alkanoylamino or aroylamino group, and Y represents the vinyl group or ethyl group which contains, in the .beta.-position, a substituent which can be eliminated by an alkali, or is the .beta.-hydroxyethyl group, and M represents a hydrogen atom or an alkali metal or the equivalent of an alkaline earth metal, and the compound (1) contains at least one sulfo or sulfato group. The compounds (1) are used for dyeing material containing hydroxy and/or carboxamide groups, in particular fiber material, such as cellulose fiber material and wool, on which they give deep blue dyeings.
