Dyestuffs of the formula <IMAGE> (1) give, on hydroxyl- and amido-containing materials, dyeings having a high fibre-dyestuff bond stability, a high stability to oxidizing agents and good wet fastness properties. The substituents are defined as follows: m=0 or 1 n=0 or 1 where m+n+n=1 or 2, X denotes vinyl or CH2CH2-Y, Y represents OSO3H, SSO3H, OCOCH3, OPO3H2, OSO2CH3, SCN, NHSO2CH3, Cl, Br, F, OCOC6H5, OSO2C6H4CH3 AND N(CH3)3+Cl-. R=H or C1-C4-alkyl which is unsubstituted or substituted by OH, halogen, SO3H, W=radical of the formula <IMAGE> in which <IMAGE> <IMAGE> <IMAGE> <IMAGE> in which R1=H or denotes C1-C6-alkyl which is unsubstituted or substituted by OH, OSo3H, SO3H or COOH.
