A method for acylating aminoanthraquinone dyes which comprises reducing the dye to the leuco form, reacting the leuco dye with an acylating agent and oxidizing the acylated leuco compound to form the desired acylated dyes. In a preferred embodiment bis 1,4-aminoanthraquinone dyes and bis 1,5,aminoanthraquinones are formylated.
