Description
Verfahren zur Erzeugung von Mischtönen auf der pflanzlichen Faser. Zusatz zum Patent 418943. In dem Patent 418943 ist ein Verfahren zur Herstellung von Mischtönen auf der pflanzlichen Faser beschrieben, welches darin besteht, daB man die. vegetabilische Faser mit einer Mischung von Produkten der deutschen Patentschrift 291o76 oder von Nitrosaminalkalisalzen und den Alkalisalzen von Körpern, welche eine kupplungsfähige, saure Methylengruppe enthalten, und der amerikanischen Patentschrift 1448251 imprägniert bzw. bedruckt und die Farbstoffe durch eine Passage in schwachen Säuren oder sauren Salzen bei Gegenwart von Oxydationsmitteln zur Entwicklung bringt.Process for the production of mixed tones on the vegetable fiber. Addendum to patent 418943. In patent 418943 is a method of manufacture of mixed tones on the vegetable fiber, which consists in the fact that one the. vegetable fiber with a mixture of products from the German patent specification 291o76 or of nitrosamine alkali salts and the alkali salts of bodies which contain a couplable, acidic methylene group, and the American patent 1448251 impregnated or printed and the dyes through a passage in weak Brings acids or acidic salts to development in the presence of oxidizing agents.
Es wurde nun gefunden, daß man zum gleichen Ergebnis gelangt, wenn man die pflanzliche Faser mit Produkten der deutschen Patentschriften264527und 293897 oder mit Diacytessigsäurearyliden oder Monoacylessigsäurearyliden klotzt, welche durch Kondensation von 2 Molekülen Acylessigester mit Diaminodiarylbasen oder von I Molekül Acylessigester mit Aminobasen der allgemeimen Formel-. NHZ - R - X - R' entstehen, worin R einen Arylrest, R' einen Arylrest oder einen eine saure Methylengruppe enthaltenden Rest, X eine Azo- oder Azoxygruppe oder den Rest eines fünfgliedrigen, heteroatomigen Ringes bedeuten, mit einer Diazolösung entwickelt unter Zusatz eines Produktes der amerikanischen Patentschrift 144825I zur Klotz- oder Diazolösung und zum SchluB mit geeigneten Oxydationsmitteln behandelt.It has now been found that one arrives at the same result if the vegetable fiber with products of the German patents 264527 and 293897 or with Diacytessigsäurearyliden or Monoacylessigsäurearyliden puddles, which by condensation of 2 molecules of acyl acyl acetate with diaminodiaryl bases or of I Molecule of acyl acetic ester with amino bases of the general formula. NHZ - R - X - R ' arise in which R is an aryl radical, R 'is an aryl radical or an acidic methylene group containing radical, X an azo or azoxy group or the radical of a five-membered, mean heteroatomic ring, developed with a diazo solution with the addition of a Product of the American patent 144825I for block or diazo solution and Finally treated with suitable oxidizing agents.
Beispiel 1.Example 1.
Der Baumwollstoff wird mit nachstehender Klotzlösung vorpräpariert
und getrocknet:
Man erhält ein dunkles Violett von hervorragenden Echtheitseigenschaften. Beispiel e.A dark purple with excellent fastness properties is obtained. Example e.
Der Baumwollstoff wird mit nachstehen-(ler Lösung vorpräpari.ert und
getrocknet:
Man erhält eine hellgrüne Färbung von hervorragenden Echtheitseigenschaften. Beispiel 3. A light green dyeing with excellent fastness properties is obtained. Example 3.
Die unpräparierte Ware wird mit nachstehender Druckfarbe bedruckt
und getrocknet:
Man erhält ein Rotbraun von hervorragenden Echtheitseigenschaften.A red-brown with excellent fastness properties is obtained.
Beispiel 4.Example 4.
Die unpräparierte Ware wird mit nachstehender Druckfarbe bedruckt:
Man erhält ein Grün von hervorragenden Echtheitseigenschaften.A green with excellent fastness properties is obtained.
Durch Änderung der Mischungsverhältnisse sowie durch Wahl der entsprechenden Azokomponenten und Basen lassen sich zahlreiche andere Nuancen herstellen.By changing the mixing ratio and choosing the appropriate one Azo components and bases can be produced in numerous other shades.
An Stelle der angeführten Oxydationsmittel können auch andere Anwendung finden. In gleicher Weise wie das lösliche Leukoderivat des Indigos können auch die entsprechenden Abkömmlinge der Halogenindigos und des Thioindigos und anderer Küpenfarbstoffe zur Verwendung kommen.Instead of the oxidizing agents listed, other uses can also be used Find. In the same way as the soluble leuco derivative of indigo can also the corresponding descendants of the halogen indigo and the thioindigo and others Vat dyes come to use.
