    Abstract: Anthraquinone dyestuffs suitable for use in dyeing and printing synthetic fiber material, particularly polyesters, and process for their preparation which comprises reacting an anthraquinone which contains, in at least one .beta.-position, a reactive group which will come off, with a phenol, an alcohol, an aromatic or aliphatic mercaptan or amine which contains an aryl radical substituted by at least 1 acylamino methylene group or an anthraquinone which contains, in at least one .beta.-position, an aryl radical attached directly or through a bridge with a methylolamide or a derivative thereof or an equivalent amount of a mixture of formaldehyde or formaldehyde-yielding compound and an aliphatic or aromatic nitrile or the amide or imide derived therefrom.

    Abstract: A process for the non-aqueous dyeing or printing of nitrogencontaining fibre material, especially fibre material made from natural or synthetic polyamide, with certain water-soluble anionic anthraquinone dyestuffs from non-polar, aprotic organic solvents is disclosed. By said process even, strongly-coloured dyeings having good fastness properties are obtained; said process is moreover advantageous in that it can be carried out without the use of solubilising agents and without fire hazard in a uniform solvent which can be easily regenerated.
