Abstract
Description
Die Erfindung betrifft einen Antikopierfilm zur Abdeckung von Do kumenten, bestehend aus einem in der Größe des abzudeckenden Do kuments oder Teilen davon vorliegenden Film transparenten Materials mit gleichmäßig wiederkehrenden, in der Stärke des Filmmaterials oder Teilen davon undurchsichtigen oder reflektie renden Abschnitten, die für einen definierten Sichtwinkelbereich auf den Film durch deren entsprechende geometrische Anordnung den Film undurchsichtig und in davon abweichenden Sichtwinkelberei chen durchsichtig erscheinen lassen.The invention relates to an anticopy film for covering Do. documents, consisting of a do to be covered in the size of the document or parts of it Material with evenly recurring, in the strength of Film material or parts thereof opaque or reflective sections for a defined viewing angle range on the film by their corresponding geometric arrangement Film opaque and in different viewing angles Chen appear transparent.
In der deutschen Patentanmeldung P 42 26 906 ist ein Antikopier film der oben bezeichneten Art beschrieben. Der Film, der Dokumente unkopierbar machen soll, besteht im wesentlichen aus einer transparenten Kunststoffolie mit eingelagerten oder auf den Filmoberflächen befindlichen undurchsichtigen Bereichen in einer Vielzahl unterschiedlicher Anordnungen, durch die der Film in der Belichtungsrichtung eines Kopiergerätes undurchsichtig und aus einem anderen Sichtwinkelbereich durchsichtig erscheint. Dabei kann der Antikopierfilm auf dem abzudeckenden Dokument mittels handelsüblicher Klebe- und Haftmittel befestigt werden.In German patent application P 42 26 906 there is an anti-copy film of the type described above. The film that To make documents uncopiable essentially consists of a transparent plastic film with embedded or on the Opaque areas in a film surface Many different arrangements, through which the film in the Exposure direction of a copier opaque and off appears transparent in another viewing angle range. Here can the anti-copying film on the document to be covered by means of commercially available adhesives and adhesives are attached.
Vorliegende Erfindung liegt die Aufgabe zugrunde, einen Antiko pierfilm zu schaffen, dessen transparentes Material mit den un durchsichtigen oder reflektierenden Abschnitten umweltverträglich ist.The present invention has for its object an antico to create pier film, whose transparent material with the un transparent or reflective sections environmentally friendly is.
Die Aufgabe wurde dadurch gelöst, daß das transparente Material mit den undurchsichtigen oder reflektierenden Abschnitten eines Antikopierfilms der eingangs geschilderten Art halogenfrei ist.The object was achieved in that the transparent material with the opaque or reflective sections of a Anticopy film of the type described above is halogen-free.
Dadurch ist das Material biologisch abbaubar und z. B. gemeinsam mit Papier kompostierbar. Das Material kann darüber hinaus nach entsprechender Vorzerkleinerung problemlos in die Wieder verwertung von Papier eingeschleust werden, da keine Fremdstoffe enthalten sind, die die Qualität des Papiers beeinträchtigen.This makes the material biodegradable and z. B. together compostable with paper. The material can also according to appropriate pre-shredding in the re recycling of paper, as there are no foreign substances are included that affect the quality of the paper.
Das eingesetzte, transparente Material ist weiterhin deshalb be sonders umweltverträglich, da es gefahrlos zu entsorgen ist, durch einfache Deponierung oder durch Verbrennung. Es werden da bei keine Schadstoffe freigesetzt, insbesondere kein PCDD oder PCDF, da alle verwendeten Materialien halogenfrei sind. The transparent material used is therefore still particularly environmentally friendly, since it can be disposed of safely, by simple landfill or by incineration. There will be with no pollutants released, especially no PCDD or PCDF, since all materials used are halogen-free.
Der erfindungsgemäße Antikopierfilm ist anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels nachfol gend näher beschrieben.The anti-copying film according to the invention is based on a Drawing schematically illustrated embodiment follow described in more detail.
Der Antikopierfilm ist in der Zeichnung im Querschnitt darge stellt und besteht aus einem in der Größe des abzudeckenden Doku ments 2 oder Teilen davon vorliegenden Film 3 aus transparentem Material mit gleichmäßig wiederkehrenden, in der Stärke des Film materials oder einem Teil davon undurchsichtigen oder reflektie renden Abschnitten 5. Diese Abschnitte können auch aufgedruckt sein. Durch zueinander versetzte Anordnung der Abschnitte er scheint ähnlich einer verstellbaren Jalousie der Film entspre chend der Kopierrichtung in der Draufsicht 6 undurchsichtig, in etwas schräger Blickrichtung 7 durchsichtig. Verschiedene Ausfüh rungsformen dieses Aufbaus des Films sind in der eingangs genann ten Schrift gezeigt und erläutert.The anti-copy film is in the drawing in cross-section represents Darge and consists of a present in the size of the covered docu ments 2 or parts thereof, film 3 made of transparent material with a uniformly recurring, in the thickness of the film material or a part thereof opaque or reflec leaders portions 5 . These sections can also be printed. By staggered arrangement of the sections he seems similar to an adjustable venetian blind the film accordingly the copy direction in the top view 6 opaque, in a somewhat oblique viewing direction 7 transparent. Various embodiments of this structure of the film are shown and explained in the aforementioned document.
Zum sicheren Anbringen des Antikopierfilms auf dem abzudeckenden Dokument ist der Film mit einer Klebstoffschicht 1 versehen, die mit einer vor der Anwendung des Films abziehbaren Schutzfolie 4 abgedeckt sein kann.In order to securely attach the anticopy film to the document to be covered, the film is provided with an adhesive layer 1 which can be covered with a protective film 4 which can be removed before the film is used.
In der Ausführung ohne Schutzfolie ist der Antikopierfilm z. B. mit einem blockfreien Heißsiegelkleber versehen. Zur Anwendung wird der Antikopierfilm von der Rolle oder vom Block oder als Bo gen unter Anwendung von Druck und Temperatur auf das zu schüt zende Dokument kaschiert.In the version without a protective film, the anti-copying film is e.g. B. provided with a non-blocking heat seal adhesive. For use is the anti-copying film from the roll or from the block or as Bo to apply the pressure and temperature laminated document.
Ist der Antikopierfilm mit einem dauerfeuchten Haftkleber be schichtet, muß zum blockfreien Trennen einzelner Antikopierfilm- Lagen eine Schutzfolie z. B. in Form eines silikonisierten Papiers oder einer entsprechend behandelten Folie eingelegt werden. Die Schutzfolie wird vor Anwendung des Antikopierfilms abgezogen. In dieser Ausführungsform kann der Antikopierfilm kalt unter aus schließlicher Anwendung von Druck laminiert werden.Is the anti-copying film with a permanently moist adhesive layers, must be used for the non-blocking separation of individual anti- Lay a protective film z. B. in the form of a siliconized paper or an appropriately treated film. The The protective film is removed before the anti-copying film is used. In In this embodiment, the anti-copying film can be cold under eventual application of pressure.
Entsprechend der geforderten Umweltverträglichkeit des Anti kopierfilms ist das transparente Material mit den undurch sichtigen oder reflektierenden Abschnitten 5 des Films 3 halogenfrei. Geeignete Filmmaterialien sind beispielsweise:In accordance with the required environmental compatibility of the anti-copying film, the transparent material with the opaque or reflective sections 5 of the film 3 is halogen-free. Suitable film materials are for example:
- - Polycaprolactone- polycaprolactones
- - Celluloseacetat- cellulose acetate
- - polymere Stärkederivate- polymeric starch derivatives
- - Homo- und Copolymere linearer Polyester der 3-Hydroxybutan- und 3-Hydroxyvaleriansäure.- Homo- and copolymers of linear polyesters of 3-hydroxybutane and 3-hydroxyvaleric acid.
Gegebenenfalls kann es zweckmäßig sein, die Materialien mit bio logisch aktiven Weichmachern und Additiven zu vermischen, die einen biologischen Abbau der Materialien fördern.If necessary, it can be useful to bio to mix logically active plasticizers and additives that promote biodegradation of the materials.
