Description

Säurefreie Lösungen von basischen Farbstoffen und Tannin Es wurde gefunden; daß sich hochkonzentrierte säurefreie Lösungen von basischen Farbstoffen herstellen lassen, die das doppelte Gewicht oder noch mehr an Tannin in Vergleich zu dem des gelösten basischen Farb= stoffies enthalten, ohne daß eine Ausfällung des basischen Farbstoffes stattfindet, wenn der Lösung Äthylenthiodiglykol oder Resorcin oder ein Gemisch beider zugesetzt wird.It was acid-free solutions of basic dyes and tannins found; that there are highly concentrated acid-free solutions of basic dyes Can be produced that are twice the weight or even more in terms of tannin in comparison to that of the dissolved basic dye without causing any precipitation of the basic dye takes place when the solution is ethylene thiodiglycol or Resorcinol or a mixture of both is added.

Daß man das Ausfallen des Tanninlackes basischer Farbstoffe durch Zusatz von Äthylenthiodiglykol oder Resorcin in Druckfarben verhindern kann, wobei die beim Druck verwendete Verdickung die Wirkung der Agenzien- noch unterstützt, ist zwar bekannt. Es war aber nicht vorauszusehen, daß sich auch hochkonzentrierte tanninhaltige Lösungen der basischen Farbstoffe herstellen lassen, welche vollkommen säurefrei sind und sich daher sehr gut als Stämmlösungen gowohl für die Bereitung von Buntätzfarben als auch für Druckpasten, die im direkten Druck gebraucht werden sollen, verwenden lassen.That the precipitation of the tannin varnish is caused by basic dyes The addition of ethylene thiodiglycol or resorcinol in printing inks can prevent, whereby the thickening used during printing supports the effect of the agents, is known. But it could not be foreseen that he would concentrate too much Let tannin-containing solutions of the basic dyes be produced, which perfectly are acid-free and are therefore very suitable as stock solutions both for preparation of colored etching inks as well as printing pastes that are used in direct printing should, let use.

Der mit der Erfindung verbundene technische Effekt besteht darin, daß nunmehr der farbstoffverbrauchenden Industrie direkt Produkte geliefert werden können; welche die zum Druck -notwendigen Agenzien bereits in einer hochkonzentrierten gelösten Form enthalten.The technical effect associated with the invention is that now products are supplied directly to the dye-consuming industry can; which already contains the agents necessary for printing in a highly concentrated contained in dissolved form.

Die bisherige Arbeitsweise zur Bereitung von Druckpasten, welche eine geraume Zeit in Anspruch nimmt, Unkosten an Dampf bzw.. Heizmaterial und nicht zuletzt auch Verluste an Farbstoff zur Folge hat, wird durch das Arbeiten mit den hochkonzentrierten Lösungen vermieden.The previous way of working for the preparation of printing pastes, which one takes a long time, expenses in terms of steam or heating material and last but not least Also, loss of dye is caused by working with the highly concentrated Solutions avoided.

Es ist nur erforderlich, die hochkonzentrierten Lösungen der basischen Farbstoffe; welche die zur weiteren Fixierung notwendigen Agenzien bereits enthalten, für den direkten Druck mit einer sauren oder neutralen Verdickung, für den Buntätzdruck mit z. B. einer formaldehydsulfoxylathältigen Verdikkung zu verrühren.It is only necessary to use the highly concentrated solutions of the basic Dyes; which already contain the agents necessary for further fixation, for direct printing with an acidic or neutral thickening, for color etching printing with z. B. to stir a formaldehyde sulfoxylate thickening.

Beispiel r1 und B werden langsam miteinander gemischt.example r1 and B are slowly mixed together.
