Description

Verfahren zur Darstellung von wasserunlöslichen Azofarbstoffen Es wurde gefunden, daß man zu wertvollen wasserunlöslichen Azofarbstoffen gelangt, wenn man die Tetrazoverbindun_gen von unsulfonierten Diaminocarbazolen oder ihren Derivaten mit den Aryliden der Oxycarbonsäuren kuppelt. Man erhält auf diese Weise gelbe, braune, violette; blaue bis tiefschwarze Farbstoffe, welche, auf der Faser erzeugt, ausgezeichnete Echtheitseigenschaften besitzen. Beispiel i Das gut ausgekochte und getrocknete Baumwollgarn wird mit einer Lösung von 12 g 2 # 3-OxynaphthoesäureaniJid, 2 0 ccm Natronlauge 3¢° B6 und 25 ccm Türkischrotöl 11 imprägniert, ausgewunden und ohne zu trocknen in einer mit Acetat abgestumpften Tetrazolösung, welche 5 g 2 # 7-Diaminocarbazol im Liter enthält, entwickelt, gespült und geseift. Man erhält auf diese Weise sehr schöne, marineblaue Färbungen. Beispiele Bei Verwendung von 2 # 3-Oxynaphthoesäure-a naphthalid und 3 # 6-Dimethyl-2 . 7-diaminocarbazol wird ein tiefblaustic,hi#7es Schwarz erhalten. Beispiel 3 Bei Verwendung von 2 # 3-Oxynaphthoesäureanilid und 3 # 6-Dic'hlor-!2 # 7-diaminocarbazol wird ein Violett erhalten.Process for the preparation of water-insoluble azo dyes It has been found that valuable water-insoluble azo dyes are obtained if the tetrazo compounds of unsulfonated diaminocarbazoles or their derivatives are coupled with the arylides of the oxycarboxylic acids. In this way, yellow, brown, violet ones are obtained; blue to deep black dyes, which, produced on the fiber, have excellent fastness properties. EXAMPLE i The well-boiled and dried cotton yarn is impregnated with a solution of 12 g of 2 # 3-oxynaphthoic acid aniJide, 2 0 ccm of sodium hydroxide solution 3 ° B6 and 25 ccm of Turkish red oil 11, wrapped and, without drying, in a tetrazo solution blunted with acetate, which 5 contains g 2 # 7-diaminocarbazole per liter, developed, rinsed and soaped. In this way, very beautiful, navy blue colorations are obtained. Examples When using 2 # 3-oxynaphthoic acid-a naphthalide and 3 # 6-dimethyl-2. 7-diaminocarbazole a deep blue, hi # 7 black is obtained. Example 3 When using 2 # 3-oxynaphthoic anilide and 3 # 6-dicloro-! 2 # 7-diaminocarbazole, a violet is obtained.

Mit anderen Diaminocarbazolen sowie mit anderen 2 # 3=Oxynaphthoesäurearyliden erhält man ähnliche Färbungen. Beispiel ¢ Die mit Diacetessigs,äuretolidiid getränkte und mit der Tetrazoverbindung von 2 # 7-Diaminocarbazol entwickelte Faser gibt ein kräftiges Gelbbraun. Mit anderen Oxycarbonsiäurearyliden und ihren Derivaten kann das Verfahren in gleicher Weise durchgeführt werden.With other diaminocarbazoles and with other 2 # 3 = oxynaphthoic acid arylides similar colorations are obtained. Example ¢ The one impregnated with diacetacetic acid, auretolidiid and fiber developed with the tetrazo compound of 2 # 7-diaminocarbazole enters strong yellow brown. With other oxycarboxylic acid arylides and their derivatives can the procedure can be carried out in the same way.
