Abstract

The invention comprises anthraquinone dyes containing, attached to a carbon atom, at least one group of the formula HO3S-O-CH2-CO-NH-CH2-The dyes are made by reacting an anthraquinone dye having an exchangeable hydrogen atom on an aromatic nucleus with a compound of the formula X-CH2-CO-NH-CH2-OH or with a mixture of a compound of the formula X-CH2-CO-NH2 and a symmetrical dihalogenodimethyl ether, X representing -OH or -O-SO3H, and when X represents -OH converting the product into its sulphuric acid ester, the reactions being carried out simultaneously or in either order. Examples are given in which the dyes are 1:4-diaminoanthraquinone derivatives. The dyes dye and print wool, silk, synthetic polyamide fibres, cellulose fibres and leather.
