Abstract

Procedure for preparing water soluble anthraquinone dyes which, in the form of the free acid, have the general formula: ** (See formula) ** where one of the radicals X and Y represents -SO3H and the other radical represents -NHCOOR, where R represents an alkyl, cycloalkyl or aralkyl group containing up to 8 carbon atoms; characterized in that it comprises reacting an anthraquinone compound of the formula: ** (See formula) ** wherein one of the radicals X1 and Y1 represents -SO3H and the other radical represents -NH2, with a chloroform acid ester of the formula: ROCOCl where R is defined as above.
