Abstract: Water insoluble disperse dyes for aromatic polyester textile material are made by the reaction of an aldehyde intermediate derived from an .alpha.-(N-alkylanilino)-m-toluenesulfonamide, typified by .alpha.-(N-ethylanilino)-m-toluenesulfonamide, with a nitrile containing an active methylene group, such as malononitrile.
