Reactive dyes, processes for their preparation and their use

Azo dyes comprising at least one structural unit of the formula (1) ##STR1## The azo dyes according to the invention are particularly suitable for dyeing cotton and wool and produce dyeings with good allround properties.

Azo dyes, their preparation and their use

Compounds of the formula ##STR1## in which the variables are as defined in the claims, which are suitable as fibre-reactive dyes for dyeing widely varying fibre materials, are described.

Dye mixtures comprising at least one reactive dye of formula ##STR1## together with at least one reactive dye of formula ##STR2## give dyeings having good fastness properties on nitrogen-containing or hydroxyl group-containing fiber materials.

Mixtures of reactive dyes and their use

Described are compounds of formula ##STR1## which are suitable as fibre-reactive dyes for dyeing and printing a very wide range of different fibre materials.

Azo reactive dyes, their preparation and use

Compounds of the formula ##STR1## in which the variables are as defined in the claims, and which are suitable as fibre-reactive dyes for dyeing and printing widely varying fibre materials, are described.

Reactive dyes, their preparation, and their use

The invention relates to compounds of formula ##STR1## wherein the variables are as claimed in the claims and which are suitable as fibre-reactive dyes for dyeing a wide range of fibre materials.

Reactive azo dyes containing an aminocarbonyl or aminosulfonyl bridge

Reactive dyes of the formula ##STR1## in which the variables have the meanings stated in the claims, are described. The dyes according to the invention are particularly suitable for dyeing cellulosic fibre materials and give dyeings with good fastness properties and a high color yield.

Fiber-reactive dyes having a central 1,3,5-triazine ring to which are

Reactive dyes of the formula ##STR1## where A, K and Z are each as defined in the claims, are especially useful for dyeing or printing cellulosic fiber materials, producing dyeings and prints having good fastness properties in a high yield.

Disazo dyes with a vinylsulfonyl type fiber-reactive radical substituted

Reactive dyes of formula ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by hydroxyl, R.sub.2 and R.sub.3 are each independently of the other hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.4 alkanoylamino, halogen or sulfo, and Y is .alpha.,.beta.-dihalopropionyl or .alpha.-haloacryloyl, are particularly suitable for dyeing or printing cellulosic fibre materials or natural or synthetic polyamide fibre materials, in high tinctorial yield, and give dyeings and prints with good fastness properties.
