Die Färbungen besitzen auf diesen Materialien gute Licht-, Wasch-, Schweiß-, Sublimations-, Plissier-, Dekatur-, Bügel-, Wasser-, Meerwasser-, Bleich-, Trockenreinigungs-, Uberfärbe- und Lösungsmittelechtheiten und besitzen außerdem eine außerordentlich gute Salzverträglichkeit..Die Farbstoffe sind auch besonders pH-stabile Produkte.The new dyes are preferably used for dyeing, padding and printing of structures made of polymers with more than 80%, acrylonitrile, for example polyacrylonitrile, and copolymers of 80 to 95 °; 'o acrylonitrile and 20 to 5% vinyl acetate, methacrylate or Metllylmethatcrylat.The dyeings have good light, washing, perspiration, sublimation, pleating, decatur, ironing, water, seawater, bleach, dry cleaning, over-dyeing and solvent fastness and also have good fastness to light an extraordinarily good salt tolerance. The dyes are also particularly pH-stable products.
Das Färben mit den beanspruchten Farbstoffen geschieht vorteilhaft in wäßrigem Medium, wobei es sich empfiehlt, in neutralem oder saurem Medium bei Kochtemperatur zu arbeiten. Die Anwendung von handelsüblichen Retarden stört nicht, obwohl die neuen Farbstoffe insbesondere geeignet sind, auch ohne Retarder auf den obengenannten Polymerisaten sehr egale Färbungen zu erzielen. Man kann selbstverständlich die Färbung auch im geschlossenen Gefäß bei erhöhter Temperatur und unter Druck durchführen, da die neuen Farbstoffe auch verkochbeständig sind. Mit den neuen Farbstoffen lassen sich auch Mischgewebe, welche einen Polyacrylnitrilfaseranteil enthalten, sehr gut färben. Sie eignen sich zum Teil auch zum Färben von Polyacrylnitril in der Masse in licht- und naßechten Tönen. Zum Teil sind diejenigen Abkömmlinge, welche eine gute Löslichkeit in organischen Lösungsmitteln besitzen, auch zum Färben von ölen, Lacken, plastischen Massen, Kunststoffen sowie von zum Verspinnen in organischen Lösungsmitteln gelösten Kunststoffmassen geeignet.Dyeing with the claimed dyes is advantageous in an aqueous medium, whereby it is advisable to use a neutral or acidic medium Cooking temperature to work. The use of standard retarders does not interfere, although the new dyes are particularly suitable, even without a retarder on the above-mentioned polymers to achieve very level colorations. Of course you can the coloration even in a closed vessel at elevated temperature and under pressure as the new dyes are also resistant to overcooking. With the new dyes mixed fabrics containing polyacrylonitrile fibers can also be used, color very well. Some of them are also suitable for dyeing polyacrylonitrile in the mass in light- and wet-fast tones. Some of those are descendants which have good solubility in organic solvents, also for dyeing oils, varnishes, plastic masses, plastics and for spinning in organic Plastic compounds dissolved in solvents are suitable.
Ferner können einzelne der neuen Farbstoffe für viele andere Zwecke eingesetzt werden, so z. B. zum Färben von tannierter Baumwolle, Wolle, Seide, regenerierter Cellulose, synthetischen Polyamidfasern und von Papier in jedem Herstellungsstadium. Es hat sich gezeigt, daß man auch vorteilhaft Gemische aus zwei oder mehreren Farbstoffen der Formel (1) einsetzen kann.Furthermore, some of the new dyes can be used for many other purposes are used, so z. B. for dyeing tannic cotton, wool, silk, regenerated Cellulose, synthetic polyamide fibers and paper at every stage of manufacture. It has been shown that mixtures of two or more dyes can also be used advantageously of formula (1) can be used.
Die neuen Farbstoffe zeichnen sich durch gute Kombinierbarkeit aus, so daß Farbsalze gleicher oder verschiedener Farbstoffklasseh für die verschiedensten Nuanceneinstellungen verwendet werden können.The new dyes are characterized by good combinability, so that dye salts of the same or different dye classes for the most diverse Nuance adjustments can be used.
In der USA.-Patentschrift 2 955 108 ist die Quaternierung von Buttergelb mit Chloramin beschrieben. Diese Verbindung unterscheidet sich von. den erfindungsgemäß hergestellten Farbstoffen grundsätzlich dadurch, daß das quaternäre Stickstoffatom direkt an den aromatischen Kern gebunden ist. Eine solche Verbindung ist im übrigen auch durch eine Kupplungsreaktion,-wie sie hierin beansprucht wird, nicht herstellbar. Dabei wird lediglich eine farblose unstabile Substanz erhalten, die als Farbstoff völlig unbrauchbar ist.In U.S. Patent 2,955,108 the quaternization of butter yellow is described with chloramine. This connection is different from. according to the invention Dyes produced basically by the fact that the quaternary nitrogen atom is bound directly to the aromatic nucleus. Such a connection is incidentally also not producible by a coupling reaction as claimed herein. Only a colorless, unstable substance is obtained, which is used as a dye is completely useless.
