Reactive dyestuffs containing monohagenotriazine and vinylsulfone groups, their preparation and use

Described are fiber-reactive, water-soluble monoazo compounds which conform to the hereinbelow indicated and defined general formula (1) and which are capable of dyeing hydroxy- and/or carboxamido-containing material, especially fiber material, such as cellulose fibers, for example cotton or regenerated cellulose fibers, and also wool and synthetic polyamide fibers in high color strength and good fastnesses. ##STR1## where M is hydrogen, an alkali metal or some other salt-forming, colorless metal, D is a 2-sulfophenyl radical which may be additionally substituted by alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, sulfo and/or carboxy or is a 1-sulfonaphth-2-yl radical which may be additionally substituted by sulfo and/or carboxy, and the group --SO.sub.2 --Y is a fiber-reactive group of the vinyl sulfone series.

Reactive dyestuff of the formula ##STR1## wherein D is a radical of a monaozo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone or nitroaryl organic dyestuff, a process for their preparation and their use for dyeing fiber materials containing OH groups and NH groups have been found.

Reactive dyestuffs containing monohalogenotriazine and vinylsulfone

According to the invention, a process for the preparation of triphendioxazines systemetrically or asymmetrically amidated on both sides comprises reducing a triphendioxazine chromophore, which is optionally already amidated on one side, to give the leuco form end amidating and re-oxidizing the leuco form. Products amidated on both sides are obtained in this manner with a high yield and product quality. Novel triphendioxazine dyestuffs are furthermore prepared in this manner.

Aluminum phthalocyanine reactive dyes

A phthalocyanine reactive dyestuff mixture having improved color levelness and combination properties comprises at least one phthalocyanine-fluoropyrimidinyl reactive dyestuff 2 and at least one phthalocyanine-vinylsulfonyl reactive dyestuff 1 or at least one phthalocyanine-monochlorotriazinyl reactive dyestuff 3, as well as one or more yellow reactive dyestuffs of the formula 4 to 9.

According to the invention, a process for the preparation of triphendioxazines symmetrically or asymmetrically amidated on both sides comprises reducing a triphendioxazine chromophore, which is optionally already amidated on one side, to give the leuco form and amidating and re-oxidizing the leuco form. Products amidated on both sides are obtained in this manner with a high yield and product quality. Novel triphendioxazine dyestuffs are furthermore prepared in this manner.

Reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein D is the radical of an organic dyestuff of the mono-azo, polyazo or metal complex azo series and the other substituents have the meaning given in the description, show improved application properties.

Reactive dyestuffs of the formula ##STR1## in which Z is a cyano-free pyrimidine reactive group and the remaining groups have the meaning given in the description, are highly suitable for the dyeing and printing of hydroxyl- or amido-containing materials.

Reactive dyestuffs having reactive fluorine-containing pyrimidyl radicals

Preparation of water-soluble reactive dyes containing vinylsulphonyl and .beta.-sulphatoethylsulphonyl groups by the oxidation of dyes containing .beta.-hydroxyethylmercapto radicals, and then sulphation and, if appropriate, conversion of the .beta.-sulphatoethylsulphonyl radical to the vinylsulphonyl radical with bases.

Process for the preparation of aminoazo dyes

Dyeing and printing of natural or synthetic OH-- and/or amido-containing materials, in particular, those made of cotton and polyamides, with reactive dyestuffs which in the form of the free acid are of the formula ##STR1## wherein A is a chromophoric radical.
