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.
利用适当的重氮化苯基底物与N-二烷基氨基烷基[α-(N-烷基苯胺基)]m-或p-甲苯磺酰胺偶联制成季铵化偶氮染料。偶联前或偶联后对偶联组分的悬垂二烷基氨基团进行季铵化。这些水溶性季铵化偶氮染料特别适用于染色丙烯纤维。
