Abstract

The invention comprises dyestuffs of the general formula <FORM:1074829/C4-C5/1> wherein R1 and R2 are hydrogen or a group <FORM:1074829/C4-C5/2> wherein one of X1 and X2 is hydrogen and the other a carboxylic acid group. They are prepared by heating the corresponding halogeno-anthraquinone and amino substituted carboxylic acid, or an ester thereof, or by heating the corresponding amino anthraquinone and halogeno benzene carboxylic acid or ester in a solvent e.g. benzyl alcohol or nitrobenzene and in the presence of an acid binding agent e.g. sodium carbonate or potassium acetate, a copper catalyst e.g. copper bronze or copper acetate, and potassium iodide. Ester groups are subsequently hydrolysed by caustic alkali. In an alternative method of preparation, leucoquinzarin is reacted with m-aminobenzoic acid in a solvent e.g. butanol in presence of boric acid or an ester thereof.
