  Verfahren zur Herstellung von Farbstoff abgebenden Blättern durch Auftragen der
Farbstoffschicht mit Hilfe eines   Druckerelverfahrens.   



   Es ist bekannt, die Farbstoffschicht von Farbstoff abgebenden Blättern (DurchschreibeDurchschlagspapieren) mit Hilfe eines Druckereiverfahrens zu erzeugen. Eine den Anforderungen der Praxis entsprechende Ausführungsart dieses Verfahrens, die wenig bzw. nicht abschmutzende, aber trotzdem sehr lange Zeit hindurch kopierfähige Blätter ergibt, ist jedoch bisher nicht bekannt geworden. Schwierigkeiten ergeben sich hauptsächlich darin, eine Farbmasse zu finden, die zur Ausführung des Druckereiverfahrens geeignet und gleichzeitig auch die zum Durchschreiben bzw. Durchschlagen erforderlichen Eigenschaften besitzt.

   Eine Lösung dieser technischen Aufgabe wird gemäss vorliegender Erfindung dadurch   herbeigeführt,   dass   zur Ausführung   des Druckverfahrens eine Druckereifarbe verwendet wird, die mit schweren Kohlenwasserstoffen verdünnt ist, von welchen als Beispiel in erster Reihe Petroleum erwähnt wird. Die Erfindung beruht also auf der Erkenntnis, dass gewöhnliche Druckereifarben durch ausschliesslichen Zusatz gewisser, schwererer Kohlenwasserstoffe, am besten Petroleum, als Verdünnungsmittel Eigenschaften erhalten, die sie zur Herstellung von   Durchschreibeblättern   oder   dj. geeignet machen.   



   Solche Kohlenwasserstoffe, wie z. B. Benzin, ferner die zum Verdünnen der Druckfarben normalerweise benutzten Firnisse,   Terpentine   usw., die als Sikkative wirken, sind aus der vorliegenden Erfindung ausgeschlossen, da sie die   Trocknung des Farbüberxuges nach erfolgtem   Bedrucken in   seiner ganzen Masse im Gefolge haben   und somit die Durchschlagsfähigkeit des Papiers sofort oder in unverhältnismässig kurzer Zeit aufheben. Auch die festen   od < -r plastis hen   fettartigen Kohlenwasserstoffe kommen für die vorliegende Erfindung nicht in Betracht, da sie als   Verdünnungsmittel   nicht verwendet werden können.

  Process for making dye donating sheets by applying the
Dye layer using a printer eluting process.



   It is known to produce the dye layer of dye-releasing sheets (carbon copy papers) with the aid of a printing process. An embodiment of this method that meets the requirements of practice and that produces sheets that are little or not soiled, but nonetheless copyable for a very long time, has not yet become known. Difficulties arise mainly in finding a color composition which is suitable for carrying out the printing process and at the same time also has the properties required for copying or stripping through.

   A solution to this technical problem is brought about according to the present invention in that a printing ink is used to carry out the printing process, which is diluted with heavy hydrocarbons, of which petroleum is mentioned as an example in the first place. The invention is based on the knowledge that ordinary printing inks, through the exclusive addition of certain, heavier hydrocarbons, ideally petroleum, acquire properties as a diluent which are useful for the production of copy sheets or dj. make suitable.



   Such hydrocarbons, such as. B. petrol, also the varnishes, turpentines, etc. normally used to dilute the printing inks, which act as siccatives, are excluded from the present invention, since they result in the drying of the color overxuges after printing in its entirety and thus the penetrability of the paper immediately or in a disproportionately short time. The solid or plastic, fatty hydrocarbons are also not suitable for the present invention, since they cannot be used as diluents.
