Description

Verfahren zur Herstellung von wasserunlöslichen Azofarbstoffen auf der Faser Es wurde gefunden, daß man zu wertvollen wasserunlöslichen Azofarbstoffen gelangt, wenn man die Diazoverbindung von Aminen der allgemeinen Formel: worin R einen Alky1-, Aralkyl- oder Arylrest bedeutet, auf der Faser mit Arylamiden von .o-Oxycarb@omsäuren derhefiexo,cyclischen Reihe, wie z. B. des Carbazols, Diphenylenoxyds und Diphenylensu@lfids, vereinigt.Process for the production of water-insoluble azo dyes on the fiber It has been found that valuable water-insoluble azo dyes can be obtained by using the diazo compound of amines of the general formula: wherein R is an alkyl, aralkyl or aryl radical, on the fiber with aryl amides of .o-Oxycarb @ omsäuren derhefiexo, cyclic series, such as. B. of carbazole, Diphenylenoxyds and Diphenylensu @ lfids, combined.

Die so erhältlichen neuen Farbstoffe ergeben wertvolle Färbungen und Drucke, die durch gute Echtheitseigenschaften, vor allem eine sehr gute Lichtechtheit, in der sie analoge Farbstoffe, z. B. der Patentschriften 620 q-59, 594 326 und 596 753, übertreffen, ausgezeichnet sind.The new dyes obtainable in this way give valuable dyeings and prints which have good fastness properties, especially very good lightfastness, in which they use analogous dyes, e.g. B. the patents 620 q-59, 594 326 and 596 753, are excellent.

Beispiel i 50 g abgekochtes Baumwollgarn werden in dem nachstehenden Grundierungsbade a eine halbe Stunde behandelt, durch Abwinden, Abquetschen oder Schleudern gut entwässert und in dem nachstehenden Färbebade b eine halbe Stunde entwickelt.Example i 50 g of boiled cotton yarn are treated in the following primer bath a for half an hour, drained well by winding, squeezing or spinning and developed in the following dye bath b for half an hour.

a) Grundierungsbad 29 i - (3'-Oxydiphenylenaxyd - 2' - car- boylamino,)-2, 5-dimethoxybenzol, 4 cemTürkischrotöl, 6 - Natronlauge 33° Be, 2 - Farmaldehydlösung 3oo/oig, 500 - kochendes Wasser i Liter.. -b) Färbebad 1,6g i-Amino-2-meth0xy-3-chlörbenzol werden mit 2,8 g Salzsäure 22° B6 und 0,7 g in etwas Wasser gelöstem N atrium- nitrit unter Eiszusatz diazotiert. ach Beendigung der Diazotierung stumpft man init etwa 2,59 Natriumacetat ab, setzt eine Lösung von 25 g Kochsalz in Wasser zu und stellt auf i Liter. Dann wird das Färbegut gespült, kochend geseift, nochmals gespült und getrocknet. Man erhält so eine schwarzbraune Färbung von sehr guter Lichtechtheit und guten @Taßechtheiteii. Beispiel 2 50 g abgekochtes Baumwollgarn werden in dein nachstehenden Grundierungsbade a. eine halbe Stunde behandelt, durch Abwinden, Ab-, quetschen oder Schleudern gut entwässert und in dem nachstehenden Färbebade b eine halbe Stunde entwickelt.a) primer bath 29 i - (3'-Oxydiphenylenaxyd - 2 '- car- boylamino,) - 2, 5-dimethoxybenzene, 4 cem turkish red oil, 6 - caustic soda 33 ° Be, 2 - Farmaldehyde solution 3oo / oig, 500 - boiling water i liter .. -b) dye bath 1.6 g of i-amino-2-methoxy-3-chlorobenzene be with 2.8 g hydrochloric acid 22 ° B6 and 0.7 g of n atrium dissolved in a little water nitrite diazotized with the addition of ice. after the end of the diazotization init is blunted, for example 2.59 sodium acetate off, sets a solution from Add 25 g of table salt in water and set up i liter. The material to be dyed is then rinsed, soaped at the boil, rinsed again and dried. A black-brown dyeing of very good lightfastness and good cup fastness is obtained in this way. Example 2 50 g of boiled cotton yarn are placed in the following primer bath a. Treated for half an hour, drained well by winding, squeezing or centrifuging and developed in the following dye bath b for half an hour.

Nach Beendigung der Diazotierung stumpft man mit etwa 2,59 Natriumacetat ab, setzt eine Lösung von 25 g Kochsalz in Wasser zu und stellt auf i Liter. Man erhält so, ein gelbstickiges Braun von guter Lichtechtheit und guten Naßechtheiten.a) Priming bath .4g i - (2 '- Oxycarbazo @ l - 3' - carboyl- ainino) -. l.-chlo, rbenzene, .l ecm turkish red oil, 6 - caustic soda 33 ° Be, 2 - formaldehyde solution 3o%, 5oo - boiling water i liter. b) dye bath 1.6 g of i-amino-2-methaxy-3-chlorobenzene be with 2.8 g hydrochloric acid 22 ° Be and 0.7 g of sodium dissolved in a little water nitrite diazotized with the addition of ice. After the end of the diazotization one is blunted with about 2.59 sodium acetate off, sets a solution from Add 25 g of table salt in water and set up i liter. This gives a yellowish brown of good lightfastness and good wetfastness.
