Abstract

The invention relates to paper, in particular a sheet of paper, preferably security paper such as a bank note, cheque or the like, the paper (1) comprising at least one window (2) therethrough bridged by a transparent film (3), such as a plastics film or a transparent paper.

Description

Die Erfindung betrifft ein Wertpapier, z.B. eine Banknote, einen Scheck od.dgl., mit mindestens einem von einer Folie überbrückten Fenster, welches das Papier durchsetzt, wobei die Folie innerhalb der Fensterkontur durchsichtig ausgebildet ist, z.B. eine Kunststoffolie ist.The invention relates to a security, e.g. a bank note, a check or the like, with at least one window bridged by a film which penetrates the paper, the film being transparent within the window contour, e.g. is a plastic film.

Sicherheitsdokumente können als Sicherheitselement einen Faden oder ein Band aufweisen, das im Dokument eingebettet ist (DE-OS 39 06 695). Das Sicherheitselement kann dabei aus einer lichtdurchlässigen Kunststoffolie bestehen, die eine sich über das Element erstreckende opake Beschichtung mit Aussparungen in Form von einzubringenden Zeichen und Muster aufweist. Außerdem enthält das Sicherheitselement in zu den Aussparungen deckungsgleichen Bereichen farbgebende und/oder lumineszierende Substanzen, durch die sich die Zeichen und/oder Muster unter geeigneten Lichtbedingungen vom Sicherheitsdokument und von der opaken Beschichtung in farblich kontrastierender Form unterscheiden. Dadurch wird erreicht, daß die Zeichen, Muster od.dgl. im Durchlicht sichtbar sind und visuell und/oder maschinell gelesen werden können.Security documents can have a thread or a tape as security element that is embedded in the document (DE-OS 39 06 695). The security element can consist of a translucent plastic film which has an opaque coating extending over the element with recesses in the form of characters and patterns to be introduced. In addition, the security element contains coloring and / or luminescent substances in areas congruent with the cutouts, by means of which the characters and / or patterns differ from the security document and from the opaque coating in a color-contrasting form under suitable lighting conditions. This ensures that the characters, patterns or the like. are visible in transmitted light and can be read visually and / or by machine.

Bekannt wurde auch ein Wertpapier, bei dem das Sicherheitselement ebenfalls in das Wertpapier eingebettet ist, die Papierfasern jedoch den Sicherheitsstreifen von jeder Seite des Sicherheitspapiers unsichtbar machen (EP-A1 279 880).Also known is a security in which the security element is also embedded in the security, but the paper fibers make the security strip invisible from each side of the security paper (EP-A1 279 880).

Die EP-A2 400 902 offenbart eine Banknote, die mindestens ein von einer Folie überbrücktes Fenster aufweist. Die Folie ist hiebei als Sicherheitselement ausgebildet und kann in verschiedenen Ausführungen vorliegen. Gemeinsam ist diesen Ausführungen, daß das Sicherheitselement mehrere Schichten aufweist, wobei eine Trägerschicht und metallische Abschnitte derart vorgesehen sind, daß in reflektiertem Licht, dem unbewaffneten Auge in jedem Fenster mindestens zwei metallische Flächen erscheinen, welche entlang der Länge des Sicherheitselementes, sich wiederholend, Bildstrukturen bilden, wobei die metallischen Flächen unterschiedliche Farbe aufweisen. Das Fenster durchsetzt die Banknote nicht und legt nur eine Seite der Folie frei, was die Kontrollmöglichkeiten einschränkt.EP-A2 400 902 discloses a bank note which has at least one window bridged by a film. The film is designed as a security element and can be available in various designs. Common to these statements is that the security element has several layers, a support layer and metallic sections being provided in such a way that in reflected light, at least two metallic surfaces appear in each window to the unarmed eye, which repetitive image structures along the length of the security element form, the metallic surfaces have different colors. The window does not penetrate the banknote and only exposes one side of the film, which limits the control options.

Bei einem Wertpapier der eingangs erwähnten Art ist die das Fenster überbrückende Folie als lichtpolarisierendes Element ausgebildet (GB-A-2 204 532). Die Anordnung der Folie ist dabei so getroffen, daß sie beidseits von Schichten, z.B. aus Papier oder Kunststoff, abgedeckt ist, wobei diese Schichten beschrieben oder bedruckt werden können. Die Folie ist, bedingt durch die miteinander fluchtenden Fenster in den beiden Außenschichten, im Fenster bereits von außen frei sichtbar. Zwischen den Außenflächen der beiden Schichten und der Folie befindet sich jeweils eine vom Fensterrand gebildete Stufe. Damit kann sich auf der Folie innerhalb der Fensterkontur Schmutz u dgl. ablagern.In the case of a security of the type mentioned in the introduction, the film bridging the window is designed as a light-polarizing element (GB-A-2 204 532). The arrangement of the film is such that it is on both sides of layers, e.g. made of paper or plastic, which layers can be written on or printed on. Due to the aligned windows in the two outer layers, the film is already freely visible from the outside in the window. Between the outer surfaces of the two layers and the film there is a step formed by the edge of the window. So dirt and the like can be deposited on the film within the window contour.

Auf dem Wertpapiersektor entstehen weiters auch Probleme dadurch, daß sich Farbkopiergeräte von immer besser werdender Qualität und Ausstattung verbreiten, die Kopien liefern, die insbesondere bei flüchtiger Betrachtung, wie sie im Geschäftsleben üblich ist, sich vom Original kaum unterscheiden lassen. Es werden daher vermehrt Anstrengungen unternommen, Verfahren zu entwickeln, die ein Kopieren von Wertpapieren unmöglich machen oder zumindest Kopien liefern, die sich in auffälliger Weise vom Original unterscheiden. So wurde schon vorgeschlagen (DE-OS 33 14 670), auf zumindest einen Teil der Oberfläche eines vertraulichen Dokumentes ein Material aufzutragen, das beim Belichten mit Illuminationslicht befähigt ist, Licht mit einer Wellenlänge zu emittieren, die verschieden ist von der Wellenlänge des Illuminationslichts. Setzt man ein solcherart präpariertes Dokument dem Illuminationslicht eines Kopierers aus und fängt das Emissionslicht mit einem Detektor auf, so kann dieser Signale erzeugen, die verwertbar sind, um mindestens einen der Schritte, die zur Vervielfältigung des Originaldokumentes im Kopierer erforderlich sind, zu unterbrechen oder aufzuheben. Das Präparieren des Dokumentes kann hiebei schwierig werden, auch kann sich das aufgetragene Material verändern oder abblättern, womit die Sicherheitsfunktion nicht mehr erfüllbar ist.Problems also arise in the securities sector due to the fact that color copiers of ever-improving quality and equipment are spreading, which provide copies which, particularly when viewed briefly, as is customary in business life, can hardly be distinguished from the original. Efforts are therefore being made to develop methods which make copying of securities impossible or at least provide copies which differ conspicuously from the original. It has already been proposed (DE-OS 33 14 670) to apply to at least part of the surface of a confidential document a material which, when exposed to illuminating light, is capable of emitting light with a wavelength that is different from the wavelength of the illuminating light. If a document prepared in this way is exposed to the illumination light of a copier and the emission light is captured with a detector, it can generate signals that can be used to interrupt or cancel at least one of the steps that are required to reproduce the original document in the copier . Preparing the document can be difficult, the applied material can also change or peel off, which means that the security function can no longer be performed.

Die Erfindung zeigt einen Weg, diesen Nachteil zu vermeiden und auch zu verhindern, daß sich auf der Folie innerhalb der Fensterkontur Schmutz u.dgl. ablagert. Es wird vorgeschlagen, bei einem Wertpapier der eingangs erwähnten Art, daß die durchsichtige Folie das Fenster ausfüllt bzw. an der Ober- und/oder Unterseite des Papieres, das Fenster überspannend, befestigt ist. Durch den erfindungsgemäßen Vorschlag wird erreicht, daß das Fenster als Öffnung bzw. offenes Fenster ausgebildet ist und die durchsichtige Folie eine Klarsichtfolie ist, die das Fenster ausfüllt, so daß die Oberfläche eben, d.h. auch an der Fensterkontur frei von einer Stufe ist. Die Folie schließt somit beidseits mit der Außenfläche des Papieres bündig ab. Dabei ist es jedoch auch möglich, die durchsichtige Folie an der Ober- und/oder Unterseite des Papieres so anzuordnen, daß die Folie das Fenster überspannt. Das Fenster ist solcherart zumindest von einer Seite her gegen den Zutritt von Schmutz verschlossen. Bei Versuchen, ein derart ausgestaltetes Papier zu kopieren, entsteht an der Stelle, an der sich das Fenster befindet, ein Klecks, der bei Farbkopierern entsprechend färbig ist bzw. bei einem Schwarzweißkopierer dunkel wird, so daß das Papier sofort leicht als Kopie erkannt werden kann. Die (Umriß-)Form des Fensters kann beliebig sein, z.B. rund, oval, polygonal usw. Die Fensterform kann jedoch auch ein Symbol für eine Papiereigenschaft, z.B. den Wert des Papieres, sein.The invention shows a way to avoid this disadvantage and also to prevent dirt and the like on the film within the window contour. deposits. It is proposed, in the case of a security of the type mentioned at the outset, that the transparent film fills the window or is attached to the top and / or underside of the paper, spanning the window. It is achieved by the proposal according to the invention that the window is designed as an opening or open window and the transparent film is a transparent film which fills the window so that the surface is flat, ie also free of a step at the window contour. The film is thus flush on both sides with the outer surface of the paper. However, it is also possible to arrange the transparent film on the top and / or bottom of the paper so that the film spans the window. The window is closed at least from one side to prevent the ingress of dirt. When trying to copy such a paper, there is a blob at the point where the window is located, which is colored with color copiers or darkens with a black and white copier, so that the paper can be easily recognized as a copy . The (outline) shape of the window can be any, for example round, oval, polygonal, etc. However, the window shape can also be a symbol for a paper property, for example the value of the paper.

Das Wertpapier kann auch als zweilagiges Sandwich aus einer normalen Papierschicht mit ausgespartem Fenster und einer zweiten, aus der Klarsichtfolie bestehenden Schicht, aufgebaut sein. Die das Fenster überbrückende Folie bzw. das das Fenster überbrückende Papier kann im Fensterbereich mit einem bevorzugt maschinenlesbaren Aufdruck bzw. mit einem applizierten, zusätzlichen Sicherheitsmerkmal versehen sein.The security can also be constructed as a two-layer sandwich from a normal paper layer with a recessed window and a second layer consisting of the transparent film. The film bridging the window or the paper bridging the window can be provided in the window area with a preferably machine-readable imprint or with an applied, additional security feature.

Die durchsichtige Folie kann auch aus transparentem Papier bestehen.The transparent film can also consist of transparent paper.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläuten. Es zeigen,

  • Fig. 1 eine Draufsicht auf eine erste Ausführungsform eines erfindungsgemäßen Papieres,
  • Fig. 2 einen Schnitt entlang der Linie II-II in Fig. 1,

  • 1 is a plan view of a first embodiment of a paper according to the invention,
  • 2 shows a section along the line II-II in FIG. 1,
  • 3 shows a section corresponding to FIG. 2, but through an embodiment modified compared to the embodiment of FIGS. 1 and 2, and
  • Fig. 4 shows a structure from a normal paper layer in connection with a second transparent or transparent film or paper layer.

In der Zeichnung ist mit 1 ein Papierblatt (Wertpapier) bezeichnet, das im dargestellten Ausführungsbeispiel mit einem Fenster 2 ovaler Form versehen ist, welches das Papier durchsetzt. Das Fenster 2 ist von einer durchsichtigen Folie 3 abgedeckt. Bevorzugt besteht diese Folie aus Kunststoff.In the drawing, 1 denotes a paper sheet (security) which, in the exemplary embodiment shown, is provided with a window 2 of oval shape which penetrates the paper. The window 2 is covered by a transparent film 3. This film is preferably made of plastic.

Bei der Ausführungsform gemäß Fig. 3 füllt die durchsichtige Folie 3 das Papier 1 (Wertpapier) aus, sodaß im Bereich des Umrisses des Fensters 2 keine Stufe besteht, sondern das Papier über seiner gesamten Oberfläche plan bleibt.In the embodiment according to FIG. 3, the transparent film 3 fills out the paper 1 (security) so that there is no step in the area of the outline of the window 2, but the paper remains flat over its entire surface.

Bei der Ausführungsform gemäß Fig. 2 ist das Fenster 2 sowohl an der Oberfläche als auch an der unteren Seite des Papieres 1 durch die Folie 3 bzw. ein transparentes Papier abgedeckt, die bzw. das mit dem Papier 1, z.B. durch Klebung, fest verbunden ist. Die Folie 3 bzw. das transparente Papier kann sich dabei auch über die gesamte Oberfläche des Papieres, d.h. bis zu den Papierrändern, erstrecken. Es ist auch möglich, das Fenster nur an einer Seite des Papieres durch eine Folie 3 bzw. eine Schicht aus transparentem Papier abzudecken. Diese Folie bzw. Schicht aus transparentem Papier befindet sich dann entweder an der Ober- oder an der Unterseite des Papieres (Fig. 4).In the embodiment according to FIG. 2, the window 2 is covered both on the surface and on the lower side of the paper 1 by the film 3 or a transparent paper which is attached to the paper 1, e.g. by gluing, is firmly connected. The film 3 or the transparent paper can also cover the entire surface of the paper, i.e. to the edges of the paper. It is also possible to cover the window only on one side of the paper with a film 3 or a layer of transparent paper. This film or layer of transparent paper is then either on the top or on the bottom of the paper (Fig. 4).
