Compounds of the formula (where R1 is a monohydroxyalkyl group and R2 is a polyhydroxyalkyl group) are obtained by reacting a 1-hydroxyalkylaminoanthraquinone containing at least two carbon atoms in the alkyl group and having in the 4-position a halogen atom or a nitro or methoxy group with an alkylamine containing at least two hydroxyl groups and at least three carbon atoms in the same alkyl radicle or by reacting a 1.4-dihydroxy-, a 1-amino-4-hydroxy- or a 1.4-diamino-anthraquinone in presence of a reducing agent or in the form of its leuco compound, if desired in admixture with the anthraquinone derivative itself, with a mixture of an alkylamine as above defined and a monohydroxyalkylamine containing at least two carbon atoms in the alkyl group, and, if desired, oxidizing the leuco compounds first formed. Starting materials specified are 1-amino-2.3-dihydroxypropane, glucamine, and 1-hydroxyethylamino - 4 - halogenanthraquinones, and reducing agents are zinc dust and sodium hydrosulphite; the anthraquinone nuclei may contain further atoms or groups. The products are soluble in water dye cellulose esters and ethers, blue shades, and in the form of their sulphuric esters may be used as acid wool dyes. In examples, (1) 1,4-dihydroxyanthraquinone and its leuco compound are reacted in isobutanol with a mixture of 1-amino-2.3-propanediol and aminoethanol, yielding after oxidation with air, a mixture consisting mainly of 1 - propanediolamino - 4 - ethanol - aminoanthraquinone, with small amounts of 1.4-dipropanediolamino- and 1,4-di-(ethanolamino)-anthraquinone; (2) leuco-1,4.5.8-tetrahydroxyanthraquinone is reacted with a mixture of 1-amino-2,3-propanediol and aminoethanol in isobutanol to give mainly 1-propanediolamino-4 - ethanolamino - 5,8 - dihydroxyanthraquinone; (3) 1 - ethanolamino - 4 - bromanthraquinone is reacted with aminopropanediol in amyl alcohol in presence of sodium and copper acetates; (4) leuco-1,4-diaminoanthraquinone is reacted with aminopropanediol and aminoethanol in isobutanol to give a leuco-compound, which on oxidation with nitrobenzene and piperidine gives the same product as in (1) above. 1 - Ethanolamino - 4 - bromanthraquinone is obtained by reacting bromine with 1-ethanolaminoanthraquinone in hydrochloric acid. The Provisional Specification describes reacting amines of the formula (in which R1 is an alkyl group having at least three carbon atoms and containing at least two hydroxyl groups and R2 is hydrogen or alkyl) either singly or in admixture with a monohydroxyalkylamine with anthraquinone derivatives of the formula (in which X is OH, NH2, or an alkylamine radicle having at least two carbon atoms and at least one hydroxyl group, Y is OH, NH2, halogen, nitro, or alkoxy and in which the anthraquinone nucleus may contain other atoms or groups) if desired in presence of a reducing agent, or on their leuco compounds, if desired in admixture with the said anthraquinone derivatives.
