Description

Verfahren zur Verbesserung von aus Papier entfernbaren Druckfarben. Nach dem Patent 4i 5535 kann man schwarze Druckfarben, die sich vom Papier leicht entfernen lassen, dadurch erhalten, daß man einer Manganfarbe fettlösliche blaue Farbstoffe zusetzt. Eine weitere Vertiefung der Farbe läßt sich, wie gefunden wurde, erzielen, wenn man das l@langanfarbpigment mit Eisentannat imprägniert und dann mit Firnis in der üblichen Weise anrührt. Die besten Ergebnisse werden erreicht, wenn man dem eisentannathaltigen Farbpigment außer dem nötigen Firnis noch einen blauen Farbstoff der in dem Hauptpatent gekennzeichneten Art zugibt.Process for improving paper-removable inks. According to the patent 4i 5535 one can use black printing inks that easily differ from the paper let remove, obtained by adding a manganese color fat-soluble blue Adding dyes. A further deepening of the color can, as has been found, can be achieved by impregnating the l @ langan color pigment with iron tannate and then mixed with varnish in the usual way. The best results are achieved if the iron tannate-containing color pigment is added to the necessary varnish adding blue dye of the type identified in the main patent.

Beispiele: 1. Zoo Gewichtsteile gefällter Braunstein werden mit einer Lösung von io Gewichtsteilen Gerbstoff (z. B. Tannin) und 12 g Ferrichlorid in Zoo Gewichtsteilen Wasser versetzt, gut durchgerührt und nach zwölfstündigem Stehen abfiltriert. Der Rückstand wird getrocknet und mit einem geeigneten Firnis gut vermahlen.Examples: 1. Zoo parts by weight of precipitated brownstone are mixed with a Solution of 10 parts by weight of tannin (e.g. tannin) and 12 g of ferric chloride in zoo Parts by weight of water are added, stirred well and after standing for twelve hours filtered off. The residue is dried and ground well with a suitable varnish.

2. Man verfährt wie in Beispiel i und verrührt den eisentannathaltigen Rückstand mit Firnis und etwa 1/2 Prozent eines Farbstoffs nach Patent ¢i55352. Proceed as in example i and stir the iron tannate containing Residue with varnish and about 1/2 percent of a dye according to Patent ¢ i5535
