Abstract

Dyestuffs which correspond to the formula <IMAGE> in which R1 denotes H or a substituent, R2 denotes alkyl or aryl, R3 denotes H, alkyl, cycloalkyl or aralkyl, R4 denotes H or a substituent, n denotes 1, 2 or 3, o denotes 0 or 1, p denotes 0 or 1 and 0 + p denotes 1 or 2, are suitable for dyeing and printing natural and synthetic fibre materials, in particular fibre materials containing nitrogen atoms, such as wool, silk, leather and polyamide fibres.
