Description
Tuschen Zur Herstellung wasserechter Tuschen versetzt man üblicherweise schwach alkalische, wäßrige Lösungen von alkalilöslichen Naturharzen, wie Schellack, oder Kunstharzen mit geeigneten Farbstoffen, z. B. Ruß oder basischen oder sauren Farbstoffen. Diese Lösungen oder Suspensionen trocknen nach dem Aufbringen auf die Unterlage wasserfest auf.Inks To produce water-resistant inks, one usually adds weakly alkaline, aqueous solutions of alkali-soluble natural resins, such as shellac, or synthetic resins with suitable dyes, e.g. B. carbon black or basic or acidic Dyes. These solutions or suspensions dry after being applied to the Waterproof underlay.
Es wurde nun gefunden, daß man ebenfalls sehr wasserechte Tuschen erhält, wenn man als alkalilösliches Harz die bei der Destillation von Butandiolen erhältlichen wasserunlöslichen Rückstände verwendet. Zur Durchführung der Erfindung eignen sich vor allem die bei der Destillation von Butandiol-r, q. erhaltenen wasserunlöslichen Rückstände. Man kann diese beispielsweise dadurch gewinnen, daß man den rohen Butandiolrückstand mit :Mineralsäure versetzt und die sich dabei ausscheidenden Anteile abtrennt. Man kann auch aus den rohen Butandiolrückständen die niedrigmolekularen, wasserlöslichen und deshalb flüchtigen Anteile durch Destillation entfernen und die zurückbleibenden wasserunlöslichen Anteile verwenden. Ein geringer Gehalt an wasserlöslichen Bestandteilen beeinträchtigt die Eignung zur Herstellung von Tuschen nicht. Durch Behandeln mit Ammoniak oder anderen flüchtigen Basen lassen sich die wasserunlöslichen Rückstände wasserlöslich machen. Die so erhaltenen wäßrigen Lösungen, denen noch organische Lösungsmittel zugesetzt sein können, werden dann mit geeigneten Farbstoffen, zweckmäßig basischen Farbstoffen, versetzt und können dann unmittelbar als Tusche verwendet werden.It has now been found that inks that are very waterfast can also be used obtained when the alkali-soluble resin used in the distillation of butanediols available water-insoluble residues are used. To carry out the invention are especially suitable for the distillation of butanediol-r, q. obtained water-insoluble Residues. This can be obtained, for example, by using the crude butanediol residue with: added mineral acid and separating off the parts that are precipitated in the process. Man The low molecular weight, water-soluble ones can also be obtained from the raw butanediol residues and therefore remove volatiles by distillation and the remaining Use water-insoluble parts. A low content of water-soluble components does not affect the suitability for the production of inks. By Treat the water-insoluble residues can be removed with ammonia or other volatile bases make water soluble. The aqueous solutions thus obtained, which are still organic Solvents can be added, then with suitable dyes, expedient basic dyes, and can then be used immediately as Indian ink will.
Die im nachstehenden Beispiel angegebenen Teile sind Gewichtsteile.
Beispiel Etwa 125 Teile eines Harzes, das durch Behandeln des Rückstandes der Destillation
von 1, 4-l utandiol mit Salzsäure erhalten wurde, bringt man durch Vermischen mit
2o bis 3o Teilen eines 2 5 %igen wäßrigen Ammoniaks, erforderlichenfalls unter Zusatz
kleiner Mengen (etwa 2%) wasserlöslicher organischer Lösungsmittel, wie Alkohol,
und 5oo Teilen Wasser in Lösung. Zu dieser Lösung fügt man eine Lösung oder Suspension
von 0,5 bis i Teil eines der nachstehend erwähnten Farbstoffe in 5oo Teilen
Wasser.
