Procedure

Blue anthraquinone dyestuffs are prepared from the reaction of 6-chloro-1,4,5-trihydroxyanthraquinone with an appropriate aniline reactant. The resultant blue dyestuffs are 6-anilino-1,4,5-trihydroxyanthraquinones which produce excellent blue dyeings on polyester fabrics, particularly polyethylene terephthalate.
