Abstract

Bei der üblichen Diazotierung von Echtfärbebasen bzw. Echtfärbesalzen und nachfolgendem Abstumpfen der dabei anwesenden Säure mit Na-acetat lassen sich Reaktivfarbstoffe im Druck neben derartigen Diazoverbindungen auf alkalisch vorgrundierter Ware in einem Einphasenverfahren nur unvollkommen fixieren, weil die dabei in den Dampf entweichenden Säuredämpfe das Alkali teilweise neutralisieren. Aus diesem Grund war man bei dieser Sachlage auf die zweiphasige Arbeitsweise angewiesen.
Diese Nachteile lassen sich erfindungsgemäß überwinden, wenn man für die Farbstoffkupplung vorgesehenen Amine mit nicht wasserdampfflüchtigen Säuren diazotiert und die pH-Einstellung (Abstumpfen) mit Salzen mittelstarker, nicht wasserdampfflüchtiger Säuren bewirkt. Es können dann Reaktivfarbstoffe einphasig neben Diazoniumverbindungen auf alkalisch vorgrundierte Ware gedruckt und ohne Verluste im Dampf fixiert werden.
