Abstract

Anthraquinone dyes of the formula <FORM:0425517/IV/1> wherein x stands for an oxyalkyl residue and y for a residue of the benzene series containing an NH2-group or an OH-group in p-position to the amino group (the groups NHx and NHy being the sole nuclear substituents in the anthraquinone nucleus), by condensing a leucobody of a 1-oxy-4-(4<1>-amino- or 4<1>-oxy)-phenylaminoanthraquinone with an oxyalkylamine; or by condensing a leuco body of a 1-oxy-4-oxyalkylaminoanthraquinone with a primary amine of the benzene series containing in p-position to the amino group a further NH2-group or an - OH group, and in either case oxidizing the condensation product to the anthraquinone derivative during or after the condensation. In an example, leuco-1-oxy-4-(4<1>-aminophenyl)-aminoanthraquinone is condensed with b -oxyethylamine in presence of sodium chlorate and boric acid in alcohol (acetate artificial silk is dyed green shades). A sample furnished under Sect. 2 (5) is prepared by condensing leuco-1-oxy-4-b -oxyethylaminoanthraquinone with p-aminophenol in presence of sodium chlorate and boric acid in methyl alcohol (blue-green shades on acetate artificial silk). Specification 423,256 is referred to.
