Description
Verfahren zur Herstellung von Druck- und Stempelfarben. Bekanntlich stellt man Druck- und Stempelfarben im allgemeinen in der Weise her, däß iran einen Farbstoff, z. B. Nigrosin, in Glycerin auflöst. Benutzt man derartige Farben auf geleimten Papier; so zeigt sich, daß dasselbe nur schlecht von der Farbe benetzt wird; das Glycerin- dringt nur sehr unvollkommen in das Papier ein, was zur Folge hat, daß der Druck sehr lange feucht bleibt und leicht verwischt werden kann, was besonders bei Herstellung von Massenauflagen von großem Nachteile ist.Process for the production of printing and stamping inks. As is well known if printing and stamping inks are generally produced in such a way that iran makes one Dye, e.g. B. nigrosine, dissolves in glycerine. If you use such colors glued paper; so it turns out that the paint does not wet it well will; the glycerine penetrates the paper only very imperfectly, which is the result has that the print stays moist for a very long time and can easily be smeared, what is particularly disadvantageous when producing mass print runs.
Es wurde nun die überraschende Beobachtung gemacht, daß diese Nachteile vermieden werden, wenn man der Färbe einen Zusatz von Cyclohexanol gibt. Eine auf .diese. Weise hergestellte Farbe zeigt ein schnelles Eindringen in das Papier und damit verbunden ein hohes Trockenvermögen. Wichtig hierbei ist noch, daß die Viscosität der Farbe durch diesen Zusatz nicht herabgesetzt wird, da das Cyclohexanol selber eine große Zähflüssigkeit besitzt. In der Patentschrift 2630¢ sind bereits als Lösungsmittel für Harze Ketone, z. B. Cyclohexanon, beschrieben, wobei auch auf die Lösungsfähigkeit von Farbstoffen hingewiesen ist. Hieraus konnte jedoch keinesfalls der Schluß gezogen «-erden, daß durch die Zugabe von Cyclohexanol zu einer Lösung eines Farbstoffes in Glvcerin die oben geschilderten Vorteile erreicht werden konnten: Beispiel. 8o Teile Nigrosin «erden in einem Gemisch von 8oo Teilen Glycerin und 8o Teilen Cyclohexanol gelöst und die Lösung zum Anreiben von 4o Teilen Ruß benutzt.The surprising observation has now been made that these disadvantages be avoided if one gives the dye an addition of cyclohexanol. One on .these. Well-produced paint shows rapid penetration into the paper and associated with it a high drying capacity. It is also important here that the viscosity the color is not reduced by this addition, since the cyclohexanol itself has a high viscosity. In the patent specification 2630 [are] as solvents for resins ketones, e.g. B. Cyclohexanone, described, also on the solvency of dyes is pointed out. However, no conclusion could be drawn from this «-Erden that by adding cyclohexanol to a solution of a dye The advantages described above could be achieved in Glvcerin: Example. 8o Parts of nigrosine earth in a mixture of 800 parts of glycerine and 80 parts of cyclohexanol dissolved and the solution used to grind 40 parts of carbon black.
