Die Verarbeitung der Farbstoffe der Formel (Z) zu Färbepräparaten erfolgt auf allgemein bekannte Weise, z.B. durch Mahlen in Gegenwart von Dispergier- und/oder Füllmitteln. Mit den gegebenenfalls im Vakuum oder durch Zerstäuben getrockneten Präparaten kann man, nach Zugabe von mehr oder weniger Wasser, in sogenannter langer oder kurzer Flotte färben, klotzen oder bedrucken.
Die Farbstoffe ziehen aus wässriger Suspension ausgezeichnet auf Textilmaterial aus vollsynthetischen oder halbsynthetischen, hydrophoben, hochmolekularen organischen Stoffen auf. Besonders geeignet sind sie zum Färben oder Bedrucken von Textilmaterial aus linearen, aromatischen Polyestern, sowie aus Cellulose-2-1/2-aoetat. Cellulosetriacetat und synthetischen Polyamiden. Auch Polyolefine, und Polyvinylverbindungen lassen sich mit ihnen färben.
Man färbt oder bedruckt nach an sich bekannten, z.B. dem in der französischen Patentschrift Nr. 1 445 375 beschriebenen Verfahren. Die erhaltene Färbungen besitzen sehr gute Allgemelneohthelten; hervorzuheben ist die Licht-, Thermofixier-, Plissier-, Sublimier-, Ozon-, Reib-, Schwelss-, Alkall- und Rauchgaseohtheit. Sehr gut sind auch die Nassechtheiten, z.B. die Wasser-, Meerwasser- und Waschechtheit. Hervorzuheben sind weiter dleUeber^färbeechtheit, die Reduktionsbeständigkeit, die Beständigkeit bei 13O0C und die guten
909831/1224
Migrab ionseigenschaften. Die Farbstoffe sind beständig gegen die Einwirkungen der verschiedenen Permanentpress-Verfahren· Ein weiterer Vorteil liegt im günstigen Deckvermögen von Polyestermaterial. Auch zum Färben von texturierten) Polyester können die Farbstoffe Verwendung finden.
Die im folgenden Beispiel genannten Teile sind Gewiohtsteile und die Prozente Gewichtsprozente. Die Temperaturen sind in Celsiusgraden angegeben.
Beispiel 1
17,3 Teile 2-Ghlor-4-nitro-anilin werden mit 100 Teilen Wasser und 25 Teilen 3Q#lger Salzsäure vermischt und auf 0° gekühlt. Man lässt darauf eine Lösung von 8 Teilen Natriumnitrit in 20 Teilen Wasser in 15 Minuten zutropfen und rührt weitere 30 Minuten. Sodann zerstört man den Ueberschuss salpertiger Säure mit Amldosulfonsäure. Nachdem man von kleinen Mengen fester Verunreinigung filtriert hat, gibt man die klare Diazoniumsalzlösung in kleinen Anteilen zu einer Lösung von 16,5 Teilen 3-Cyan- -^-äthyl-o-hydroxypyridon^ In ein auf 0* gekühltes Gemsich aus 100 Teilen Wasser und 100 Teilen Pyridln. Nach beendeter Kupplung wird der abgeschiedene Farbstoff abfiltriert, neutral gewaschen und getrocknet. Die orangefarbenen bis roten Kristalle färben synthetische Fasern in echten, gelben Tönen.
