Azo reactive dyestuffs have the following formula

Polyfunctional azo reactive dyestuffs

Disazo reactive dyestuffs containing fiber-reactive radicals

Dyeings having improved properties are obtained with a dyestuff of the following formula ##STR1## wherein the substituents have the meaning given in the description.

Process for dyeing and printing materials containing hydroxyl and/or

Novel reactive dyestuffs of the general formula ##STR1## in which A represents CH.dbd.CH, or CH.sub.2 --CH.sub.2 Z, in which Z denotes a substituent which can be split off under dyeing conditions, and in which the other groups have the meaning given in the description, show improved application properties.

Diazo reactive dyestuffs, their preparations and use

Azo class reactive dyestuffs have been found which have the general formula (1) ##STR1## and in which Z.sup.1 and Z.sup.2 represent a reactive group from the pyrimidine series, X represents SR.sup.1, OR.sup.2 or NR.sup.3 R.sup.4, and the remaining substituents have the meanings given in the description, which dyestuffs are particularly suitable for dyeing hydroxyl- and amido-containing fibres, in particular cotton.

Reactive disazo dyestuffs which contain two heterocyclic reactive groups

Reactive dyestuffs of the formula ##STR1## in which the substituents have the meanings given in the description are highly suitable for the dyeing and printing of cellulose materials and nitrogen-containing materials. They produce dyeings and prints having good wet and light fastness properties.

Reactive dyestuffs

New reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein the substituents have the meaning given in the description, are suitable for dyeing and printing materials containing hydroxyl groups or amide groups, in particular cellulose materials.

Reactive dyestuffs containing hydroxy naphthalene disulphonic acids

Phthalocyanine reactive dyestuffs which, in the form of the free acid, have the formula (1) ##STR1## in which the variable radicals have the meaning given in the description, are prepared by condensation of the corresponding amines with cyanuric fluoride or cyanuric chloride in any desired order. The reactive dyestuffs according to the invention exhibit good wet and light fastness properties and are used for the dyeing and printing of cotton.

Phthalocyanine reactive dyestuffs

2,4-diamino-6-fluorotriazine diazo reactive dyestuffs

The novel triphendioxazine dyestuffs of the formula ##STR1## in which the substituents R, R', T.sub.1, T.sub.2, X, Y and n have the meanings given in the description are highly suitable for the dyeing and printing of cellulose-containing or amido-containing material.

Triphendioxazine dyestuffs

The invention relates to an improved process for the preparation of dyestuffs based on at least one triphendioxazine which is linked to a further chromophore via a triazine at a pH of 5.5 to 2.0 and a temperature of 50 to 100.degree. C.

Process for the preparation of reactive dyestuffs

Dyestuffs of the formula ##STR1## wherein X=--CH.dbd.CH.sub.2, --CH.sub.2 --CH.sub.2 OSO.sub.3 H, --CH.dbd.CHCl or --CH.sub.2 --CH.sub.2 Cl and

Amino disazo dyestuffs containing a fluoropyrimidinyl or a

Dyestuffs in the form of their free acid have the following formula (1) ##STR1## in which the substituents have the meaning given in the description. The dyestuffs according to the invention are suitable for dyeing hydroxyl-containing fiber materials in yellow shades.

Reactive azo dyestuffs obtained by coupling diazotized

The new triphendioxazine dyestuffs of the formula ##STR1## in which the substituents have the meaning given in the description are suitable for the dyeing and printing of cellulose-containing and amido-containing materials.

The new o-aminoazo compounds of the formula ##STR1## in which the substituents D, A, R and R.sub.1 and the index n have the meaning given in the description are valuable intermediates for the preparation of metal complex dyestuffs and are also highly suitable for the dyeing of wool and polyamide.
