Dyes of the general formula (1):where M is hydrogen, alkali, ammonium or the equivalent of an alkaline earth metal ion, X is halogen, alkoxy or an N-containing heterocycle, Q is a grouping of the formula (e) where Y is vinyl or an alkali-eliminable grouping and W is alkyl which may be interrupted by an O or an NR groupand the radicals Rand Rrepresent alkyl, alkoxy, alkylcarbonylamino, arylcarbonylamino, and also the radicals Rand Rare alkyl or hydrogen, their preparation and their use for dyeing and printing hydroxyl- and/or carboxamido-containing material, preferably fiber material.

Water-soluble fiber-reactive colorants, method for the production thereof, and use their use

The disclosed dyes (which are fiber-reactive and are useful for dyeing materials containing OH and/or carboxamide groups) are compounds of the formula (1)

Water-soluble fiber-reactive dyes, processes for their preparation, and

Dyes containing a 5,6-difluoropyrimidin-4-yl radical as fiber-reactive group are useful for dyeing hydroxy- and/or carboxamido-containing material, including fiber material, for example cellulose fibers, wool and polyamide.

Water-soluble fiber-reactive dyes, preparation thereof and use thereof

Fibre-reactive dyestuffs based on barbituric acid, of the following formula ##STR1## wherein the substituents have the meaning given in the description, are distinguished by improved properties.

Reactive dyestuffs based on a substituted barbituric acid

Reactive dyestuffs of the formula ##STR1## produce bluish red dyes having excellent fastness properties on hydroxyl- and amido-containing fibre material.

Naphthylazonaphthol dyes which contain a 5-chloro-6-fluoropyrimidin-4-yl

Reactive dyestuff mixtures containing one or more monochlorotriazine dyestuffs of the formula (1) ##STR1## and one or more monofluorotriazine dyestuffs of the formula (2) ##STR2## in which the substituents have the meaning given in the description, show on-tone exhaustion onto fibres and are fixed uniformly even under different fixation conditions.

Bifunctional reactive dyestuff mixture

A process for preparing the sulphone of the formula ##STR1## consists in reductive cleavage of disazo/disazoxy dyestuffs of the formula ##STR2## in which B is a direct bond or a bridging member and

Process for preparing

Monoazo reactive dyestuffs of the formula ##STR1## wherein the substituents have the meaning given in the description, are particularly suitable for dyeing materials containing OH groups or amide groups.

Monoazo 2-hydroxy-pyridone-containing reactive dyestuffs

Reactive dyestuff containing triazinyl and halopyrimidine moieties

Azo dyestuffs of the formula ##STR1## having the substituent meanings given in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups and amide groups.

Azo dyestuffs and intermediate products for their preparation

Dyestuff of the formula ##STR1## wherein FB=the radical of a dyestuff

Polyfunctional fibre-reactive dyestuffs

Reactive dyestuffs of the formula ##STR1## in which ##STR2## and Z=a heterocyclic reactive group and the remaining groups have the meaning indicated in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups or amide groups.

Reactive dyestuffs

The reactive dyes of the formula ##STR1## in which the substituents and indices have the meaning given in the description, are outstandingly suitable for dyeing or printing naturally occurring or synthetic materials containing hydroxyl or amide groups.

Copper complexes of 4-fluoro-5-chloropyrimidin-6-yl containing ractive

Reactive dyestuffs of the formula ##STR1## and the meanings of substituents given in the description produce on hydroxyl- and amido-containing fibre materials orange dyeings which are fast to boiling.

Reactive monoazo dyestuffs which contain alkylbenzene and chlorofluoro

Dyestuffs of the formula ##STR1## in which the substituents have the meanings given in the description are suitable for the dyeing and printing of hydroxyl- and amido-containing materials.
