Abstract

1594. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Jan. 21. Dyes, artificial.-Leuco-bodies of thioindigo dyes are obtained by heating a-oxythionaphthenes or alphaoxythionaphthene carboxylic acids, unsubstituted or otherwise, with a soluble thiosulphate and glycerine in presence of water to a temperature exceeding 100‹ C. with exclusion of air. A thiosulphate of the alkali or alkaline-earth metals may be used and, in the absence of water of crystallization, a small quantity of water is added. The leuco-bodies obtained yield, on oxidation, blue, violet, to red dyestuffs.
