Abstract

An anthraquinone vat dye is prepared by treating 1.4.5-tri - (a -anthraquinonylamino) - anthraquinone with aluminium chloride or an acid condensing agent containing aluminium chloride. In an example the condensation product of 1.4.5-triaminoanthraquinone with three mols of 1-chloranthraquinone is heated with sodium-aluminium chloride at 180--210 DEG C. and then treated with acid bichromate to give a dye giving reddish-khaki shades on cotton. German Specification 262,788 is referred to.
