Abstract

Dyestuffs have the formula <IMAGE> in which the benzene ring or naphthalene ring A optionally contains further substituents, in addition to sulpho groups, R is H, alkyl (C1-4), R1 and R2 are H or optionally substituted alkyl or cycloalkyl, and R1 and R2 together with the nitrogen atom to which they are attached for a heterocyclic ring which may contain a further hetero-atom, R3 is H, alkyl (C1-4) or acylamino, R4 is H, alkyl (C1-4), alkoxy (C1-4), carboxyl or sulpho and n is 1, 2 or 3. These dyestuffs are suitable for dyeing and printing fibre materials containing hydroxyl groups or amide groups, in particular fibre materials of cotton.
