Abstract

Dyestuffs of the formula ##STR1## wherein the substituents 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. The dyeings obtained with the dyestuffs are distinguished by good to very good fastness properties, in particular by outstanding fastness to wet processing.
