Abstract
Process for the preparation of substituted alpha-phenylaminoanthraquinone dyes, characterized in that an anthraquinone compound of the formula I, ** (See formula) ** in which Y1 and Y2 mean hydrogen or the hydroxyl group and Z1 and Z2 hydrogen or, if Y1 and Y2 are for hydrogen, they also mean halogen, or a mixture of this compound with its leuco compound, is reacted in the presence of boric acid or boric acid derivatives, with an amine of the formula II, ** (See formula) ** in which A means a phenylene radical, optionally containing substituents that do not dissociate acid in water, and R1 and R2 signify hydrogen, a lower alkyl group, a lower alkenyl group, or a lower hydroxyalkyl group, or R1 and R2 mean, together with the nitrogen atom, the radical of a 5- or 6-membered heterocyclic ring, to get to a compound of formula III, ** (See formula) ** in which Y1, Y2, Z1 and Z2 have the significance indicated in formula I and * A, R1 and R2 have the significance indicated in formula II.
