Description

Die Erfindung betrifft Verfahren zum Herstellen eines mehrlagigen Wertdokumentsubstrats, nach dem Verfahren erhältliche Wertdokumentsubstrate und Wertdokumente, insbesondere Banknoten, mit einem solchen Wertdokumentsubstrat.The invention relates to methods of producing a multi-layered value document substrate, value document substrates obtainable by the method and value documents, in particular banknotes, having such a value document substrate.

Wertdokumente im Sinne der Erfindung sind unter anderem Banknoten, Aktien, Anleihen, Urkunden, Gutscheine, Schecks, Flugscheine, hochwertige Eintrittskarten, Etiketten zur Produktsicherung, Kredit- oder Geldkarten, aber auch andere fälschungsgefährdete Dokumente, wie Pässe, Ausweiskarten oder sonstige Ausweisdokumente.Value documents within the meaning of the invention include banknotes, stocks, bonds, certificates, vouchers, checks, air tickets, high-quality entrance tickets, labels for product security, credit or debit cards, but also other forgery-prone documents, such as passports, ID cards or other identity documents.

Wertdokumente, insbesondere Banknoten, werden üblicherweise aus Papiersubstraten gefertigt, die besondere Sicherheitsmerkmale, wie z.B. einen zumindest teilweise in das Papier eingearbeiteten Sicherheitsfaden und ein Wasserzeichen, aufweisen und die in der Regel aus Baumwollfasern hergestellt sind. Es existieren zahlreiche Ansätze, die Haltbarkeit solcher Wertdokumente zu verbessern, z.B. durch Lackierung der bedruckten Banknoten, durch Zusatz von Verstärkungsfasern oder durch Einsatz von Plastiksubstraten bzw. Polymersubstraten. Lackierungen haben den Nachteil, dass zwar die Verschmutzung reduziert wird, die mechanischen Eigenschaften aber kaum verbessert werden. Verstärkungsfasern wirken sich zwar vorteilhaft auf die mechanische Beständigkeit aus, der Grad der Verschmutzung wird durch die höhere Porosität des Papiers aber eher größer, sodass zusätzliche Beschichtungen aufgebracht werden müssen. Eine Übersicht zum Thema Plastikbanknoten findet sich z.B. im Artikel E. L. Prime, D. H. Solomon: "Australiens Plastikbanknoten: eine wirksame Waffe gegen Geldfälschungen", Angewandte Chemie, 2010, Band 122, Seiten 2-13 . Polymersubstrate, die in Plastikbanknoten Verwendung finden, haben verglichen mit Papiersubstraten unter anderem den Nachteil, dass die Nachstellung eines Wasserzeichens nicht ohne weiteres möglich ist. Zwar besteht die Möglichkeit, ein Wasserzeichen-ähnliches Erscheinungsbild drucktechnisch zu erzeugen. Für den Betrachter sind allerdings große Unterschiede zu einem echten Wasserzeichen erkennbar. Das Dokument WO 2004/028825 offenbart ein Verfahren zum Herstellen eines mehrlagigen Wertdokumentsubstrats mit zumindest einem zwischen zwei Folien eingebetteten und mit zumindest einem Wasserzeichen versehenen Papierstreifen, umfassend: a) das Bereitstellen einer ersten Folienbahn und einer zweiten Folienbahn; b) das Einbetten des Papierstreifens, der mit Wasserzeichen versehen ist, zwischen die erste Folienbahn und die zweite Folienbahn; c) das Zuschneiden des im Schritt b) erhaltenen Verbundes.Value documents, in particular banknotes, are usually made of paper substrates which have special security features, such as a security thread at least partially incorporated into the paper and a watermark, and which are usually made of cotton fibers. There are numerous attempts to improve the durability of such documents of value, for example by coating the printed banknotes, by adding reinforcing fibers or by using plastic substrates or polymer substrates. Paint finishes have the disadvantage that, although the pollution is reduced, the mechanical properties are hardly improved. Although reinforcing fibers have an advantageous effect on the mechanical resistance, the degree of contamination is rather greater due to the higher porosity of the paper, so that additional coatings must be applied. An overview of plastic banknotes can be found eg in the article EL Prime, DH Solomon: "Australia's Plastic Banknotes: an effective weapon against counterfeiting", Angewandte Chemie, 2010, Volume 122, pages 2-13 , Polymer substrates used in plastic banknotes have the disadvantage, among other things, that paper watermarking is not readily possible compared to paper substrates. Although it is possible to produce a watermark-like appearance by printing technology. For the viewer, however, big differences to a real watermark are recognizable. The document WO 2004/028825 discloses a method of making a multi-ply value document substrate having at least one paper strip embedded between at least one watermark and comprising: a) providing a first film web and a second film web; b) embedding the paper strip, which is watermarked, between the first film web and the second film web; c) the trimming of the composite obtained in step b).

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile des Standes der Technik zu beheben. Insbesondere soll der Fälschungsschutz von Polymersubstraten, die in Plastikbanknoten Verwendung finden, erhöht werden.The invention has for its object to overcome the disadvantages of the prior art. In particular, the counterfeit protection of polymer substrates used in plastic banknotes should be increased.

Diese Aufgabe wird durch die in den unabhängigen Ansprüchen definierten Merkmalskombinationen gelöst. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the feature combinations defined in the independent claims. Further developments of the invention are the subject of the dependent claims.

Ausführliche Beschreibung der Erfindung Banknoten auf Basis von Folienverbunden bzw. Verbunden aus Papier mit außen aufgebrachten Folienlagen sind im Stand der Technik bekannt, siehe z.B. die WO 2004/028825 A2 und die US 2009/0291245 A1 .Detailed description of the invention Banknotes on the basis of film composites or composites made of paper with externally applied film layers are known in the prior art, see, for example, US Pat WO 2004/028825 A2 and the US 2009/0291245 A1 ,

Gemäß einem Vergleichsbeispiel der vorliegenden Erfindung wird ein mit Wasserzeichen versehener Papierstreifen zwischen zwei Folienbahnen eingebettet.According to a comparative example of the present invention, a watermarked paper strip is embedded between two film webs.

Gemäß der vorliegenden Erfindung werden einzelne Papier-Flicken bzw. Papier-Patche, die jeweils mit zumindest einem Wasserzeichen versehen sind, zwischen zwei Folienbahnen eingebettet.According to the present invention, individual paper patches, each provided with at least one watermark, are embedded between two film webs.

Allgemein kann der Schritt des Einbettens der Papierstreifen oder der Papier-Flicken insbesondere direkt nach einem Extrudierprozess, durch den die Folienbahnen bereitgestellt werden, erfolgen.In general, the step of embedding the paper strips or the paper patches can in particular be carried out directly after an extrusion process, by which the film webs are provided.

Alternativ kann der Schritt des Einbettens in einem dem Extrudierprozess nachgelagerten Arbeitsgang, z.B. in einem Kaschierschritt, erfolgen. Hierfür eignen sich z.B. Polyurethan-Klebstoffe oder Acrylatklebstoffe. Die Polyurethanklebstoffe können einkomponentig oder zweikomponentig sein. Die Herstellung einer mehrlagigen Folie z.B. durch Coextrusion durch zwei oder mehr Breitschlitzdüsen ist in der Fachliteratur bekannt. Die Herstellung einer mehrlagigen Folie direkt ohne Kaschierung wird z.B. in der WO 97/46367 A1 beschrieben.Alternatively, the step of embedding may take place in an operation subsequent to the extrusion process, for example in a laminating step. For this example, polyurethane adhesives or acrylate adhesives are suitable. The polyurethane adhesives may be one-component or two-component. The production of a multilayer film, for example by coextrusion through two or more slot dies, is known in the specialist literature. The production of a multilayer film directly without lamination is eg in the WO 97/46367 A1 described.

Die einzubettenden Papierstreifen oder Papier-Flicken können gemäß einer weiteren Alternative über eine Inline-Thermolaminierung eingebettet werden. Hierfür eignen sich z.B. Polyurethan-Klebstoffe oder Acrylatklebstoffe. Die Polyurethanklebstoffe können einkomponentig oder zweikomponentig sein.The paper strips or paper patches to be embedded can be embedded according to a further alternative via an inline thermal lamination. For this purpose, e.g. Polyurethane adhesives or acrylate adhesives. The polyurethane adhesives may be one-component or two-component.

Bei dem Papierstreifen kann es sich insbesondere um einen breiten Streifen, aber auch um einen (schmalen) Papierfaden handeln.The paper strip may in particular be a wide strip, but also a (narrow) paper thread.

Bei dem erfindungsgemäß eingesetzten Wasserzeichen kann es sich je nach Herstellung des Papiers um ein zweistufiges Wasserzeichen mit einem starken Hell-Dunkel-Effekt oder um ein mehrstufiges Wasserzeichen mit weichen Übergängen zwischen Hell und Dunkel und detailreicher Darstellung eines Motivs handeln. Der Begriff "mehrstufig" ist dabei in Abgrenzung zu zweistufigen Hell-Dunkel-Wasserzeichen zu verstehen und umfasst alle Wasserzeichen mit mehr als zwei Helligkeitsstufen und schließt insbesondere auch Wasserzeichen mit kontinuierlichen Hell-Dunkel-Übergängen ein. Für die Herstellung mehrstufiger Wasserzeichen wird in ein Entwässerungssieb einer Papiermaschine ein dreidimensionales Relief eingebracht, sodass die Papierdicke des fertigen Papiers entsprechend dem Relief variiert bzw. moduliert ist und im Durchlicht weiche, graduelle Übergänge zwischen helleren und dunkleren Bereichen erkennen lässt. Hierzu ist beispielsweise aus der WO 2008/071325 A1 ein Entwässerungssieb für die Herstellung von Papier mit mehrstufigen Wasserzeichen bekannt. Das Entwässerungssieb weist ein Trägersieb auf, das in einem Teilbereich ein mehrstufiges Relief in Form des zu erzeugenden Wasserzeichens aufweist, wobei das mehrstufige Relief durch einen spritzgegossenen, perforierten Wasserzeicheneinsatz gebildet ist. Das mit einem solchen Entwässerungssieb erzeugte Papiersubstrat kann im Bereich des mehrstufigen Wasserzeichens sehr dünn sein, sodass das Papiersubstrat in diesem Bereich vorteilhaft mittels der in der vorliegenden Erfindung zum Einsatz kommenden Folienbahn stabilisiert wird.Depending on the production of the paper, the watermark used according to the invention can be a two-level watermark with a strong light-dark effect or a multi-level watermark with smooth transitions between light and dark and detailed representation of a motif. The term "multi-level" is to be understood in contrast to two-stage light-dark watermark and includes all watermarks with more than two brightness levels and includes in particular watermarks with continuous light-dark transitions. For the production of multi-level watermarks, a three-dimensional relief is introduced into a dewatering screen of a paper machine, so that the paper thickness of the finished paper is varied or modulated according to the relief and soft, gradual transitions between brighter and darker areas can be detected in transmitted light. This is for example from the WO 2008/071325 A1 a drainage screen for the production of paper with multi-level Watermarks known. The dewatering screen has a carrier screen, which has a multi-level relief in the form of the watermark to be produced in a partial area, the multi-level relief being formed by an injection-molded, perforated watermark insert. The paper substrate produced with such a dewatering screen may be very thin in the area of the multi-level watermark, so that the paper substrate in this area is advantageously stabilized by means of the film web used in the present invention.

Es wird bevorzugt, dass zumindest eine Folienbahn, insbesondere beide Folienbahnen, transparent ist bzw. sind. Die Folienbahn basiert z.B. auf Polyestern, Polyolefinen (z.B. Polyethylen oder Polypropylen, insbesondere biaxial orientiertes Polypropylen BOPP), Polyamiden oder Polycarbonaten. Polyester-Folien, insbesondere Polyethylenterephthalat-Folien (PET-Folien) werden bevorzugt eingesetzt. Als Folienbahn kann darüber hinaus ein Laminat aus mehreren Kunststoffen eingesetzt werden, z.B. ein im oben erwähnten Artikel Angewandte Chemie, 2010, Band 122, Seiten 2-13 , beschriebener LLDPE/PP/LLDPE-Film (LLDPE = lineares Polyethylen niederer Dichte; PP = Polypropylen).It is preferred that at least one film web, in particular both film webs, is or are transparent. The film web is based, for example, on polyesters, polyolefins (for example polyethylene or polypropylene, in particular biaxially oriented polypropylene BOPP), polyamides or polycarbonates. Polyester films, in particular polyethylene terephthalate films (PET films) are preferably used. As a film web beyond a laminate of several plastics can be used, for example, in the above-mentioned article Angewandte Chemie, 2010, Volume 122, pages 2-13 , described LLDPE / PP / LLDPE film (LLDPE = linear low density polyethylene, PP = polypropylene).

Des Weiteren können die jeweils ein Wasserzeichen aufweisenden Papierstreifen oder Papier-Patche jeweils mit weiteren Sicherheitsmerkmalen kombiniert sein, z.B.

  • mittels Laserstrahlung erhältliche Sicherheitsmerkmale, wie etwa eine Papier-Schwärzung (z.B. in Form von Zeichen), eine Verfärbung Laser-sensitiver Farbstoffe, mittels Laser-Ablation behandelte Druckfarbe, mittels Laserschneiden erzeugte Sicherheitsmerkmale wie z.B. Aussparungen bzw. Fenster, insbesondere in Form eines Musters; die Erzeugung der Sicherheitsmerkmale kann gegebenenfalls in einem späten Stadium bei der Herstellung des Wertdokuments erfolgen;
  • mittels Verprägung, insbesondere mittels Stichtiefdruckverfahren erhältliche Präge-Merkmale;
  • mittels Laserstrahlung behandelte, mit Druckfarbe bedruckte Bereiche; die mit Laserstrahlung behandelte Druckfarbe wird dabei ablatiert, sodass bedruckte Bereiche in Form eines Musters erhältlich sind; als Druckfarbe einsetzbar sind z.B. auf Effektpigmenten basierende Farben.
Furthermore, each of the watermarks having paper strips or paper patches may be combined with other security features, eg
  • security features obtainable by means of laser radiation, such as paper blackening (eg in the form of characters), discoloration of laser-sensitive dyes, laser-ablated printing ink, security features produced by means of laser cutting, such as eg recesses or windows, in particular in the form of a pattern; the generation of the security features may, if appropriate, take place at a later stage in the production of the value document;
  • by means of embossing, in particular by means of intaglio printing available embossing features;
  • Laser-treated, ink-printed areas; the laser-treated ink is ablated so that printed areas are available in the form of a pattern; can be used as printing ink, for example, based on effect pigments colors.

Der Nachteil reiner Polymersubstrate ist unter anderem die schlechte Verprägbarkeit im Stichtiefdruckverfahren. Die erfindungsgemäß erhältlichen, Papier aufweisenden Wertdokumentsubstrate hingegen lassen sich im späteren Stichtiefdruckverfahren ausgezeichnet verprägen, d.h. die Papier-Bereiche weisen gegenüber den reinen Folienbereichen eine höhere Taktilität auf. Dies hängt mit der Kompressibilität und Verformbarkeit des Faserverbundes zusammen. Auf diese Weise kann ein Wertdokument, wie z.B. eine Banknote, auf Basis des erfindungsgemäßen Substrats vollflächig so verprägt werden, dass die Verprägung nur in den Papierbereichen eine Taktilität aufweist. Die Taktilität kann insbesondere in perfekter Passerung (d.h. in registergenauer Anordnung) zu dem Papierstreifen oder dem Papier-Patch vorliegen.The disadvantage of pure polymer substrates is, inter alia, the poor verprägbarkeit in intaglio printing. On the other hand, the value-document substrates having paper according to the invention can be embossed excellently in the later intaglio printing process, ie the paper areas have a higher tactility than the pure film areas. This is related to the compressibility and deformability of the fiber composite. In this way, a value document, such as a banknote, on the basis of the substrate according to the invention can be embossed over the entire area such that the embossing has a tactility only in the paper areas. In particular, the tactility may be in perfect registration (ie, in register registration) with the paper strip or paper patch.

Weiterhin wird bevorzugt, dass zumindest eine der in der vorliegenden Erfindung zum Einsatz kommenden Folienbahnen, insbesondere beide Folienbahnen, zusätzlich mit Sicherheitselementen, wie Beugungsstrukturen, einem Sicherheitsdruck, Flüssigkristallschichten, Dünnschichtaufbauten, Fluoreszenzstoffen, magnetischen, leitfähigen und/oder metallischen Schichten, versehen wird bzw. werden. Gemäß einer vorteilhaften Variante wird die Folienbahn (insbesondere beide Folienbahnen) im Bereich des Wasserzeichens mit einem solchen Sicherheitselement versehen. Mittels der genauen, geometrischen Anordnung des Wasserzeichen-Motivs als erstes Motiv und des Sicherheitselement-Motivs der Folienbahn (nachstehend auch als "Folienelement-Motiv" bezeichnet) als zweites Motiv kann für den Betrachter ein übergeordnetes drittes Motiv erzeugt werden. Denkbar ist z.B. eine benachbarte oder angrenzende Anordnung des Wasserzeichen-Motivs und des Folienelement-Motivs in Form einer "Nebeneinanderstellung" beider Motive. Denkbar wäre des Weiteren die Anordnung des Wasserzeichen-Motivs und des Folienelement-Motivs in räumlicher Überlagerung bzw. Superposition.It is further preferred that at least one of the film webs used in the present invention, in particular both film webs, is additionally provided with security elements such as diffraction structures, security printing, liquid crystal layers, thin-film structures, fluorescent materials, magnetic, conductive and / or metallic layers. become. According to an advantageous variant, the film web (in particular both film webs) is provided with such a security element in the region of the watermark. By means of the exact, geometric arrangement of the watermark motif as the first motif and the security element motif of the film web (hereinafter also referred to as "foil element motif") as the second motif, a higher third motif can be generated for the viewer. It is conceivable, e.g. an adjacent or adjacent arrangement of the watermark motif and the foil element motif in the form of a "juxtaposition" of both motifs. Furthermore, the arrangement of the watermark motif and the foil element motif in spatial superimposition or superposition would be conceivable.

Weiterhin ist es möglich, dass eine und/oder beide Folien, zwischen denen ein Papier-Patch eingebettet wird, eine z.B. mittels Stanzen oder durch Laser-Schnitt erhältliche Aussparung aufweist. Die Aussparung kann gleich oder unterschiedlich zu der Form des Papier-Patches sein. Es wird aber bevorzugt, dass die Aussparung eine geringere flächenmäßige Abmessung wie die des Papier-Patches aufweist. Insbesondere die folgenden Varianten sind denkbar:

  • oberhalb einer Aussparung in einer ersten Folie wird ein Papier-Patch appliziert; oberhalb des Papier-Patches wird vollflächig eine zweite Folie (die keine Aussparung aufweist) aufgebracht;
  • oberhalb einer Aussparung in einer ersten Folie wird ein Papier-Patch appliziert; oberhalb des Papier-Patches wird vollflächig eine zweite Folie, die ebenso wie die erste Folie eine Aussparung aufweist, aufgebracht; die beiden Aussparungen können insbesondere deckungsgleich oder (leicht) zueinander verschoben, d.h. überlappend, vorliegen.
Furthermore, it is possible for one and / or both foils, between which a paper patch is embedded, to have a recess available, for example, by means of punching or by laser cutting. The recess may be the same as or different from the shape of the paper patch. However, it is preferred that the recess has a smaller areal dimension than that of the paper patch. In particular, the following variants are conceivable:
  • above a recess in a first film, a paper patch is applied; above the paper patch, a second film (which has no recess) is applied over the entire area;
  • above a recess in a first film, a paper patch is applied; above the paper patch, a second film, which has a recess just like the first film, is applied over the whole area; the two recesses can in particular be congruent or (slightly) shifted from one another, ie overlapping.
