    Abstract: The invention comprises dyes of the formula wherein n is from 2 to 6 and R and R1 are each alkyl radicals of 1-3 carbon atoms or together with the nitrogen atom form a saturated mononuclear heterocyclic radical, and their acid addition and quaternary ammonium salts. The dyes are made by heating b-chloro- or b bromo-anthraquinone with an alkylene diamine of the formula in pyridine, and if desired treating the tertiary amine obtained with a quaternating agent. The dyes dye hair in yellow shades. In examples, 2 (b diethylaminoethylamino)-, 2 - (g - di - ethylaminopropylamino)- and 2 - (b - morpholinoethylamino) anthraquinone are made and quaternated with dimethyl sulphate.
