ABSTRACT:
Quaternized azo dyes made by coupling an appropriate diazotized benzenoid base with an N-dialkylaminoalkylene [.alpha.(N-alkylanilino)] m- or p-toluenesulfonamide. Quaternization of the pendant dialkylamino group of the coupling component is carried out before or after coupling. The water soluble quaternary azo dyes are especially useful for coloring acrylic fibers.
