Abstract

In making a film for projection of a single picture on a screen, a copy is made by xerography on a support pref. coated with Zn oxide and this is applied to a self-adhesive flexible transparent film. The difficulties associated with making an electrostatic copy directly on a projection film, i.e. lack of adhesion of the print to the smooth surface, are overcome.

Verfahren zum Herstellen einer Pro3ektiönsfolieMethod for producing a protective film

Die Erfindung "betrifft ein Verfahren zürn Herstellen einer Projektionsfolie. : . .. " . : --_-.-'The invention "relates to a method for producing a projection film.:. ..". : --_-.- '

Derartige Verfahren sind /bereits bekannt, wie Z0B* das fotografische Herstellen eines Positivfilmes zum Zwecke der Projektion eines fotografischen Bildes auf einen Wandschirm, Dieses Verfahren ist jedoch relativ teuer und umständlich. Such processes are / already known, such as Z 0 B * the photographic production of a positive film for the purpose of projecting a photographic image onto a wall screen. However, this process is relatively expensive and cumbersome.

Der Erfindung liegt die Aufgäbe zugrunde, eine Projektionsfolie mit Hilfe der Elektrofotografie herzustellen, und zwar ohne Verwendung von teurem Filmmaterial. -. The invention is based on the object, a projection film made with the help of electrophotography, without the use of expensive film material. -.

Dies ist z.B. mit dem sogenannten xerographischen Verfahren möglich, bei dem ein Bild unmittelbar auf einen unbeschichteten Kopieträger ,.also auch auf eine Projektionsfolie kopiert werden kann. Hierbei verhindert aber die glatte Oberfläche der Folie eine ausreichende Bindung des aufgeschmolzenen Farbpulvers, so daß das.kopierte Bild auf der Folie leicht verwischt werden kanne Dieser Nachteil soll durch die Erfindung vermieden werden.This is possible, for example, with the so-called xerographic process, in which an image can be copied directly onto an uncoated copy carrier, i.e. also onto a projection film. Here, however, the smooth surface of the foil prevents adequate bonding of the molten coating powder, so that das.kopierte image can be blurred easily in the slide e This drawback is to be avoided by the invention.

Die Erfindung besteht darin, daß ein kopiertes Bild von einer auf elektrostatischem Wege erstellten Kopie öder Druckfolie auf eine selbstklebende, lichtdurchlässige Folie mittels Klebekontakt haftend übertragen wird. Durch die Klebefolie ,ist eine gute Haftung des Bildes gewährleistet, so daß die Gefahr des Verwischens nicht besteht.The invention is that a copied image of a Electrostatic copy or printing film is transferred to a self-adhesive, translucent film by means of adhesive contact. The adhesive film ensures that the picture adheres well, so there is no risk of it being smudged does not exist.

Eine vorteilhafte Ausbildung der Erfindung besteht darin, daß das kopierte Bild von einem mit Zinkoxyd beschichteten Kopieträger übertragen wird. Hierdurch wird eine besonders intensive Übertragung erzielt.An advantageous embodiment of the invention is that the copied image is transferred from a copy carrier coated with zinc oxide. This is a particularly intense one Transfer achieved.

Es ist ferner von Vorteil, daß die lichtdurchlässige folie aus glasklarem, flexiblem Material "besteht, welches sich besonders gut für die Projektion eignet0 It is also advantageous that the translucent film consists of crystal-clear, flexible material "which is particularly suitable for projection 0

Das Verfahren besteht in der Praxis darin, daß eine transparente Folie, die auf einer Seite mit einer Klebeschicht versehen ist, unter leichtem Druck mit ihrer Schichtseite auf die Bildseite einer auf elektrostatischem Wege erzeugten Kopie oder Druckfolie aufgelegt und danach abgezogen wird, wobei die !Farbpartikel des kopierten Bildes an der Klebeschicht haften und das Bild somit auf die Folie übertragen wird»In practice, the method consists in that a transparent film, which is provided with an adhesive layer on one side, under light pressure with its layer side on the image side of an electrostatically generated copy or printing film is applied and then peeled off, the color particles of the copied image adhering to the adhesive layer and the image thus is transferred to the film »
