10 Die Verbindungen der Formel II sind bekannt. Die Verbindungen der Formel III lassen sich, soweit sie nicht ebenfalls bekannt sind, leicht, in Analogie zur Herstellung ähnlicher Verbindungen, herstellen. Diazotieren und Kuppeln wird gemäss allgemein bekannten Methoden durchgeführt. is Die Verarbeitung der neuen Verbindungen der Formel I 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 Zu-20 gäbe von mehr oder weniger Wasser, in sogenannter langer oder kurzer Flotte färben, klotzen oder bedrucken. 10 The compounds of formula II are known. Unless they are also known, the compounds of the formula III can easily be prepared analogously to the preparation of similar compounds. Diazotization and coupling are carried out according to generally known methods. is The processing of the new compounds of formula I into dyeing preparations is carried out in a generally known manner, e.g. by grinding in the presence of dispersants and / or fillers. With the preparations, which may have been dried in vacuo or by atomization, it is possible, after adding more or less water, to dye, pad or print in a so-called long or short liquor.

Die Farbstoffe ziehen aus wässriger Suspension ausgezeichnet auf Textilmaterialien aus vollsynthetischen oder halbsynthetischen, hydrophoben, hochmolekularen organi-25 sehen Stoffen auf. Besonders geeignet sind sie zum Färben, Klotzen oder Bedrucken von Textilmaterial aus linearen, aromatischen Polyestern, sowie aus Cellulose-2 '/2-acetat, Cellulosetriacetat und synthetischen Polyamiden. Sie zeichnen sich insbesondere durch hervorragendes Thermomigrier-30 verhalten aus. The dyes are excellently absorbed from aqueous suspensions on textile materials made from fully synthetic or semi-synthetic, hydrophobic, high-molecular organic substances. They are particularly suitable for dyeing, padding or printing on textile material made from linear, aromatic polyesters, as well as from cellulose 2 '/ 2-acetate, cellulose triacetate and synthetic polyamides. They are characterized in particular by their excellent Thermomigrier-30 behavior.

Man färbt, klotzt oder bedruckt nach an sich bekannten, z.B. den in der französischen Patentschrift Nr. 1 445 371 beschriebenen Verfahren. Dyeing, padding or printing according to known, e.g. the methods described in French Patent No. 1,445,371.

125 Teile Wasser, 44 Teile konz. Salzsäure und 17.3 Teile 4o 2-Chlor- 4-nitroanilin werden 12 Stunden verrührt, danach mit 45 Teilen Eis und im Verlauf von 40 Minuten, bei 0 bis 2\ mit 7,0 Teilen Natriumnitrit, gelöst in 25 Teilen Wasser, versetzt. Unter Kühlung auf 0 bis 5: wird 2 Stunden weitergerührt, die überschüssige salpetrige Säure mit wenig Ami-45 dosulfonsäure zerstört, sodann von geringen Mengen an festen Verunreinigungen abfiltriert. Die so erhaltenen Diazoni-umsalzlösung wird im Verlauf von 45 Minuten unter Rühren und Kühlen (durch Eiszugabe) auf 0 bis 5:; zu einer Lösung von 33,2 Teilen N-Äthyl- N-(2'-o-diphenoxyäthyl)-anilin in so 400 Teilen Eisessig und 140 Teilen Eiswasser sehr langsam zugegeben. Nach beendeter Kupplung rührt man noch 2 Stunden ohne Kühlung nach, filtriert, wäscht den Rückstand säure- und salzfrei und trocknet ihn bei 60e im Vakuum. 125 parts water, 44 parts conc. Hydrochloric acid and 17.3 parts of 4o 2-chloro-4-nitroaniline are stirred for 12 hours, then with 45 parts of ice and over the course of 40 minutes, at 0 to 2% with 7.0 parts of sodium nitrite, dissolved in 25 parts of water. With cooling to 0 to 5: stirring is continued for 2 hours, the excess nitrous acid is destroyed with a little ami-45-dosulfonic acid, then small amounts of solid impurities are filtered off. The diazonium salt solution thus obtained is brought to 0 to 5 in the course of 45 minutes with stirring and cooling (by adding ice); added very slowly to a solution of 33.2 parts of N-ethyl-N- (2'-o-diphenoxyethyl) aniline in 400 parts of glacial acetic acid and 140 parts of ice water. After the coupling has ended, the mixture is stirred for a further 2 hours without cooling, filtered, the residue is washed free of acid and salt and dried at 60 ° in vacuo.
