Abstract

The invention comprises mixtures of anthraquinones of the formula where X1 and X2 are hydroxy, amino or alkylamin groups, Y is a substituted or unsubstituted alkyl or aralkyl group which is free from sulphonic and carboxylic acid groups, and R is an aryl group substituted by -OZ, where Z is hydrogen, a substituted or unsubstituted alkyl group or an aryl or cycloalkyl group, and R may contain further substituents other than nitro, amino, carboxylic or sulphonic acid groups, e.g. alkyl or halogen. The mixtures are prepared by treating the leuco derivative of with the aldehyde corresponding to Y. These compounds are in turn obtained by reacting 4 : 8-(X1X2) 1 : 5-dihydroxyanthraquinone-2 : 6-disulphonic acid with HR in sulphuric acid medium containing boric acid with subsequent splitting off of the sulphonic acid groups. The compounds are used to dye textiles comprising synthetic fibres reddish-blue.
