Abstract

Dyestuffs of the formula: ##SPC1## In which PA1 R.sup.1 is H, benzyl, sulphobenzyl or an alkyl group of 1-4 carbon atoms which may be substituted by OH, CN, OSO.sub.3 H, CO.sub.2 H, halogen, SO.sub.3 H or NHQ, Q representing a cellulose-reactive group, PA1 R.sup.2 is H, or an alkyl group of 1-4 carbon atoms which may be substituted by OH, CN, OSO.sub.3 H, CO.sub.2 H, halogen or SO.sub.3 H, or PA1 Nr.sup.1 r.sup.2 is the N-linked radical of a nitrogen-containing heterocyclic compound containing 5 or 6 atoms in the heterocyclic ring, PA1 R.sup.3 is H or an alkyl group of 1-4 carbon atoms which may be substituted by OH, PA1 R.sup.4 is benzyl which may be substituted by SO.sub.3 H or NHQ, an alkyl group of 1 to 4 carbon atoms which may be substituted by OH, SO.sub.3 H or NHQ or a phenyl radical which may be substituted by SO.sub.3 H, CO.sub.2 H, halogen, alkyl or alkoxy of 1 to 4 carbon atoms or NHQ, and the benzene ring A may be further substituted by an alkyl or alkoxy group of 1-4 carbon atoms, halogen, NO.sub.2 or NHQ, and wherein NR.sup.1 R.sup.2 and NR.sup.3 R.sup.4 are different and the dyestuff as a whole contains 1 or 2 cellulose-reactive groups and at least one further SO.sub…
