Abstract: Uniformly dyed water-swellable cellulosic fibers which have been produced by contacting water-swellable cellulosic fibers successively or simultaneously with water, with ethylene glycol, propylene glycol or derivatives of these and with an essentially water-insoluble dye of the formula where Y is unsubstituted or substituted phenyl or naphthyl or an unsubstituted or substituted saturated or unsaturated 5-membered or 6-membered heterocyclic radical, two of the three radicals X are hydroxyl and the remaining radical X is where A is chlorine, bromine, cyano, nitro, an aliphatic, cycloaliphatic, araliphatic or aromatic radical and n is 0, 1, 2 or 3 and where, if n>1, the radicals are identical or different. Deep reddish blue to green dyeings or prints are obtained. The dyeings have very good fastness characteristics.

Abstract: anthraquinone is made from diamino anthraquinone mixts. by (1) acylation with oxalic acid, (2) nitration to the dinitro cpd.,(3) reduction to the diamino cpd., and (4) deacylation to the tetra-amino cpd. Used together with its methylation prods., as dyes for regenerated cellulose fibres. Yields and product quality are higher than from the known process using acetic anhydride instead of oxalic acid for acylation. Purity of the prod. is adequate for dyestuff use.
