    Abstract: Water-sol. solvent (I) of formula: YO-CHX-CH2-(O-CHX-CH2)n-OH (which X is H or Me; Y is H or 1-4C) alkyl; and n is 0 - 8) is used in prepn. of title cpd. (II) by reaction of 1,4-dihydroxyanthraquinone with prim. aliphatic and/or aromatic amines in presence of 1,4-diamino- or 1,4-dihydroxy-2,3-dihydroanthraquinone. Compared with alcohols used in prior art, cpds. (I) allow higher resistant concs. and are more easily sepd. from prod. (e.g. by distn.). (III) are known dispersion dyes for plastics and synthetic fibres and prepersion dyes for plastics and synthetic fibres and precursors for other dyes.
