Abstract

Process for the preparation of acid anthraquinone dyes, characterized in that a 1,4-diaminoanthraquinone of the formula I ** (See formula) ** in which A 'is the radical of a diphenylalkane, diphenylcycloalkane, diphenyl ether or optionally substituted diphenyl thioether which is linked to the nitrogen atom by a carbon atom of a benzene ring and contains in the benzene ring at least one replaceable hydrogen atom , Y R1 and R2 each represents a lower alkyl group, optionally substituted, it is reacted with a sulfonation agent to arrive at a mixture of anthraquinone dye of the average composition of formula II, ** (See formula) ** in which A means one of the radicals corresponding to the radical A ', of a diphenylalkane, diphenylcycloalkane, diphenylether or optionally substituted diphenyl thioether, which is linked by carbon atoms of the benzene ring to the nitrogen and sulfonic acid group, and n means 1 or 2, and R1 and R2 have the significance indicated in formula I.
