    摘要： Dyestuffs having the general formula: ##STR1## wherein Z.sup.1 and Z.sup.2 each independently represent oxygen or ##STR2## in which Y is hydrogen, an optionally substituted hydrocarbon radical or an acyl radical,R.sup.1 and R.sup.2 each independently represent a substituted or unsubstituted aryl radical, preferably phenyl, andX.sup.1 and X.sup.2 each independently represent hydrogen, halogen, cyano, alkyl, alkoxy, nitro, amino, substituted amino, carboxylic acid, carboxylic acid ester, optionally substituted carbamoyl, alkylthio, arylthio, alkylsulphonyl, arylsulphonyl, acyl, acyloxy, hydroxy, sulphonic acid or sulphonic acid ester, orX.sup.1 and X.sup.2 together form a 5- or 6-membered, carbocyclic or heterocyclic, saturated or unsaturated, including aromatic, ring which may carry further substituents; processes for the manufacture of these dyestuffs and their use for coloring aromatic polyester textile materials.

    摘要： A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-hydroxy-2-(optionally substituted) lower alkyl-4-anilinoanthraquinone optionally having from 1 to 3 substituents in the anilino nucleus. Preferably the latter carries a single substituent ortho to the --NH--group.
