Dyestuffs of the formula ##STR1## wherein R.sub.1 and R.sub.2 are each hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sub.3 is phenyl substituted with sulpho have the meaning given in the description, and their use for the dyeing and printing of textile materials containing hydroxyl groups and containing nitrogen, especially textile materials consisting of natural and regenerated cellulose, and also those consisting of wool, silk and synthetic polyamide and polyurethane fibers. Dyeings obtained distinguish themselves by good fastness properties and high brilliancy.

One-amine-2-sulpho-4-[(4-halo-6-amino

Dyestuffs of the formula ##STR1## wherein X, R, R.sub.1, R.sub.2 and R.sub.3 have the meaning given in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing.

Anthraquinone reactive dyestuffs, their preparation and their use for

Dyestuffs of the formula ##STR1## wherein X, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the meaning indicated in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing.

Anthraquinone reactive dyestuffs

Dyestuffs of the formula ##STR1## wherein R.sub.1 and R.sub.2 have the meaning given in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing. The dyeings obtained are distinguished by good fastness to light and wet processing.

Anthaquinone reactive dyestuffs, their preparation and their use for

##STR1## wherein n, m, p, X, R.sub.1, R.sub.2 and R.sub.3 have the meaning indicated in the description, and their use for dyeing and printing materials containing hydroxyl groups or containing amide groups, such as textile fibres, filaments and fabrics made of wool, silk and synthetic polyamide fibres and polyurethane fibres and for the wash-fast dyeing and printing of natural or regenerated cellulose.

Dyestuffs of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, m, n, p and X have the meaning given in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and woven fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose in dyeings and prints which are fast to washing. Blue dyeings and prints which are fast to light and wet processing are obtained.

Dyestuffs of the formula ##STR1## wherein D, W, R.sub.1, R.sub.2, R.sub.3, x and D' have the meaning indicated in the description, and their use for dyeing and printing textile materials containing hydroxyl groups and textile materials containing nitrogen, in particular textile materials of natural and regenerated cellulose, and also of wool, silk, and synthetic polyamide and polyurethane fibres. The resulting dyeings are distinguished by good fastness properties.

Anthraquinone-azo reactive dyestuffs

Dyestuffs of the formula ##STR1## wherein S, m, X, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and n have the meaning indicated in the description, and their use for dyeing and printing textile materials containing hydroxyl groups and textile materials containing nitrogen, in particular textile materials of natural and regenerated cellulose, and furthermore of wool, silk and synthetic polyamide and polyurethane fibres. The resulting dyeings are distinguished by good fastness to light and wet processing.

Reactive dyestuffs of the formula ##STR1## WHEREIN R.sub.1, R.sub.2, R.sub.3, X, Y and Z have the meaning given in the description and their use for the dyeing and printing of materials which contain hydroxyl groups and materials which contain N, such as cotton, wool and the like, by the customary processes.
