Water-soluble monoazo compounds of the general formula (1) which dye in fast, mainly red shades materials which contain carboxamide and/or hydroxy groups, preferably in the form of fibers, in particular cellulose fiber materials. ##STR1## in which: Y is .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-chloroethyl, vinyl or .beta.-sulfatoethyl,

Water-soluble monoazo compounds containing a p-aminophenylamino- and

Precursors for the preparation of fiber-reactive triphendioxazine dyestuffs correspond to the general formulas: ##STR1## in which Y' is a vinyl, a beta-hydroxyethyl or an ethyl group which contains in the beta-position a substituent which can be eliminated by an alkali;

Precursors for the preparation of water-soluble triphendioxazine

Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) ##STR1## in which: n is the number 0 or 1;

Precursors for synthesis of triphendioxazine dyestuffs

Water-soluble triphendioxazine compounds having fiber-reactive dye properties conforming to the general formula ##STR1## where: B is --O-- or --S-- or --NH-- or (C.sub.1 -C.sub.6)-alkylamino;

Sulfonyl containing compounds suitable as precurors for water-soluble

Water-soluble triphendioxazine compounds of the formula ##STR1## having at least one sulfato or sulfo group, in which R is a hydrogen atom, a water-solubilizing group, an alkyl group having 1 to 6 carbon atoms which is substituted by an acidic group, or an optionally substituted sulfonamide group,

Water-soluble triphendioxazine compounds

Triphendioxazine compounds with properties of fiber-reactive dyestuffs corresponding to the general formula ##STR1## in which T is an optionally substituted alkyl group with 1 to 6 carbon atoms, excluding a radical of the group Y defined below, it also being possible for the alkyl group to be interrupted by hetero atoms, or is an optionally substituted aryl group,

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,

Water-soluble triphendioxazine compounds which have valuable fiber-reactive dyestuff properties and correspond to the general formula (1) and dye materials, in particular cellulose fiber materials, containing carboxamide and/or hydroxy groups in fast shades. ##STR1## in which: B is a group --O--, --S--, --NH-- or --N(R')-- in which R' is alkyl having 1 to 6 carbon atoms;
