    摘要: Dyestuffs of the formula: ##SPC1##In whichR.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,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, orNr.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,R.sup.3 is H or an alkyl group of 1-4 carbon atoms which may be substituted by OH,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.3 H group.The dyestuffs are particularly suitable for dyeing cellulose textile materials in the presence of alkalies to give bright reddish or violet shades having good fastness to washing. The light fastness of the new dyes is much better than could have been expected from the known fastness of basic xanthene dyes applied to cellulose with the aid of mordants.

    摘要: The water-insoluble monoazo dyestuffs, free from sulphonic acid and carboxylic acid groups, which are of the formula: ##STR1## wherein Y is hydrogen, lower alkyl, optionally substituted phenyl or nitro; Z is nitro, cyano, optionally substituted phenyl, optionally substituted lower alkoxycarbonyl or carbonamido; T is hydrogen, optionally substituted lower alkyl or optionally substituted lower alkoxy;W is an acylamino group of the formula: ##STR2## wherein X.sup.1 is hydrogen or lower alkyl, X.sup.2 is hydrogen or an optionally substituted hydrocarbon or heterocyclic radical, and A is a direct link or --0-- or ##STR3## and R.sup.1 and R.sup.2 each independently represent a hydrogen atom or an optionally substituted alkyl radical or R.sup.1 and R.sup.2 together form with the nitrogen atom N a 5- or 6-membered nitrogen-containing heterocyclic ring, a process for the manufacture of the said dyestuffs by diazotization and coupling, and the use of the said dyestuffs for coloring synthetic textile materials, in particular aromatic polyester textile materials which they color in violet to green shades possessing excellent fastness to light, to wet treatments and to dry heat treatments.
