Description

Die vorliegende Erfindung betrifft eine Oberfläche, die mit Hilfe von Hilfsmitteln oder per Hand abgerubbelt werden kann. Weiterhin betrifft sie ein Verfahren zur Herstellung einer derartigen Rubbeloberfläche.The present invention relates to a surface which can be rubbed off by means of tools or by hand. Furthermore, it relates to a method for producing such a rubbed surface.

Rubbeloberflächen sind im Alltagsgebrauch vor allem aus dem Bereich von Sofortgewinn-Lotterielosen oder ähnlichen kleineren Glücksspielen bekannt. Weiterhin finden sie Anwendung im Bereich der Telefonkarten, bei denen die sogenannte PIN (personal identification number) durch ein mit einer Rubbeloberfläche versehenes Etikett oder eine auftransferierte Rubbelschicht abgedeckt wird.Scratch surfaces are known in everyday life, especially from the field of instant win lottery tickets or similar smaller games of chance. Furthermore, they are used in the field of telephone cards, in which the so-called PIN (personal identification number) is covered by a label provided with a rubbed surface or a clear coat.

Allgemein dienen Rubbeloberflächen der Abdeckung von Informationen oder dem Erkennen der Tatsache, dass eine Person sich Zugang zu diesen Informationen verschafft hat. Neben der eigentlichen Rubbelschicht werden zur Erhöhung der Produktsicherheit oftmals zusätzliche Sicherheitsmerkmale in die Rubbeloberfläche integriert. In der EP 0974951 A2 beispielsweise wird ein Rubbeletikett beschrieben, das an seiner Unterseite einen sogenannten VOID-Effekt und an seiner Oberseite zusätzliche Authentizitätsmerkmale wie Aufdrucke, Gravuren der Rubbelschicht oder Hologramme aufweist.Generally, scratching surfaces serve to cover information or to detect the fact that a person has obtained access to that information. In addition to the actual scratch-off layer, additional security features are often integrated into the scratch-off surface to increase product safety. In the EP 0974951 A2 For example, a scratch-off label is described which has on its underside a so-called VOID effect and on its upper side additional authenticity features such as imprints, engravings of the scratch-off layer or holograms.

Speziell Hologramme haben sich als Authentizitätsmerkmal und ansprechendes Design-Element für Rubbeloberfläche vielfach bewährt. Ein Nachteil dieser Produkte ist jedoch, dass sie sehr kostspielig sind: Sie müssen in einem zusätzlichen Arbeitsgang auf die Rubbelschicht auftransferiert oder auflaminiert werden. Ein direktes Einprägen einer holographischen Struktur in die Rubbelschicht ist nicht möglich, da sie aufgrund ihrer weichen Beschaffenheit zerstört würde.Especially holograms have proven themselves as authenticity feature and appealing design element for scratching surface many times. However, a disadvantage of these products is that they are very costly: they must be finely applied or laminated to the scratch-off layer in an additional operation become. A direct imprinting of a holographic structure in the scratching layer is not possible because it would be destroyed because of its soft nature.

Eine Rubbeloberfläche, die ein geprägte Lackschicht aufweist, ist in der WO 03/066344 A1 gezeigt.A rubbed surface having an embossed lacquer layer is in WO 03/066344 A1 shown.

WO 02/18152 A1 zeigt eine Rubbeloberfläche, bei der die Rubbelschicht und die geprägte Schicht aufeinander angeordnet sind. WO 02/18152 A1 shows a Rubbeloberfläche in which the scratch-off layer and the embossed layer are arranged on each other.

Der Erfindung liegt daher die Aufgabe zugrunde, eine kostengünstigere Rubbeloberfläche in einem einfacheren Herstellungsprozeß bereitzustellen, die mit Merkmalen in der Art einer Prägung ausgestattet ist.The invention is therefore based on the object to provide a cheaper Scratch surface in a simpler manufacturing process, which is equipped with features in the form of an embossing.

Die Aufgabe der Erfindung wird gelöst durch eine Rubbeloberfläche gemäß den Ansprüchen 1-15 sowie durch ein Verfahren gemäß den Ansprüchen 16-28. Dabei wird auf eine Rubbelschicht eine zusätzliche Lackschicht aufgebracht, die im weiteren Verlauf durch Prägung mit einer holographischen Struktur versehen wird. Völlig überraschenderweise hat sich bei Versuchen ergeben, dass es möglich ist, eine über der Rubbelschicht befindliche Lackschicht zu prägen ohne dass es zu Verletzungen der Rubbelschicht oder zu ungenauen Holographie-Bildern kommt. Dies war aufgrund der Weichheit der Rubbelschicht nicht zu erwarten.The object of the invention is achieved by a Rubbeloberfläche according to claims 1-15 and by a method according to claims 16-28. In this case, an additional lacquer layer is applied to a scratch layer, which is provided in the further course by embossing with a holographic structure. Surprisingly, it has been found in experiments that it is possible to emboss a lacquer layer located above the scratch-off layer without causing damage to the scratch-off layer or to inaccurate holography images. This was not to be expected due to the softness of the scratch-off layer.

Im Folgenden wird die Erfindung anhand der Figuren 1 und 2 näher beschrieben. Die Zeichnungen sind nicht maßstäblich zu verstehen. Insbesondere Schichtdicken werden zur Verbesserung der Anschaulichkeit stark übertrieben groß dargestellt.In the following, the invention is based on the FIGS. 1 and 2 described in more detail. The drawings are not to scale. In particular layer thicknesses are greatly exaggerated to improve the clarity.

In Fig. 2 wird ein Etikett 201 zum Abdecken von Informationen, beispielsweise einer PIN, gezeigt, das auf einer Trägerbahn 202 liegt. Das Etikett besteht aus einer transparenten Basisfolie 204, die unterseitig mit einer Klebstoffschicht 203 ausgestattet ist. Auf seiner Oberseite ist eine Rubbelschicht 205 aufgebracht. Bei dieser Rubbelschicht handelt es sich um eine Farbschicht, die durch Abreiben, beispielsweise mit Hilfe eines Fingernagels oder einer Münze, entfernbar ist. Über dieser Rubbelschicht 205 ist ein Hologramm-Verbund 206 aufgebracht, bestehend aus einer haftvermittelnden Schicht 207 und einer Holographiefolie 208. Mit Hilfe der haftvermittelnden Schicht 207, beispielsweise einem Klebstoff, wird die Holographiefolie 208 auf der Rubbelschicht 205 fixiert.In Fig. 2 For example, a label 201 for covering information, such as a PIN, that is on a carrier web 202 is shown. The label consists of a transparent base film 204, which is provided on the underside with an adhesive layer 203. On its upper side a scratch layer 205 is applied. This scratch-off layer is a color layer that can be removed by rubbing, for example with the aid of a fingernail or a coin. Over this scratch-off layer 205, a hologram composite 206 is applied, consisting of an adhesion-promoting layer 207 and a holographic film 208. With the help of adhesion-promoting Layer 207, for example an adhesive, the holographic foil 208 is fixed on the scratch-off layer 205.

In Fig. 1a ist ein analog nummeriertes Etikett mit einer erfindungsgemäßen Rubbeloberfläche 110a dargestellt. Anstatt eines Hologramm-Verbundes wird hier eine Lackschicht 109a aufgetragen. Nach oder während der Trocknung wird darin ein Hologramm eingeprägt. Die erfindungsgemäße Rubbeloberfläche 110a besteht daher aus der Rubbelschicht 105a und der geprägten Lackschicht 109a.In Fig. 1a An analogously numbered label with a rubbing surface 110a according to the invention is shown. Instead of a hologram composite, a resist layer 109a is applied here. After or during drying, a hologram is imprinted in it. The scratch-off surface 110a according to the invention therefore consists of the scratch-off layer 105a and the embossed lacquer layer 109a.

Vorzugsweise ist die Lackschicht 109a zwischenschichtfrei auf die Rubbelschicht 105a aufgetragen, so dass beide Schichten in direktem Kontakt zueinander stehen. Wie oben erläutert, kann die Prägung überraschenderweise trotz einer zwischenschichtfreien Aufbringung und trotz der Verwendung von weichen Rubbelschichten durchgeführt werden, ohne dass Qualitätsverluste der Prägung oder eine Verletzung der Rubbelschicht einträten.The lacquer layer 109a is preferably applied to the scratch-off layer 105a without interlayer, so that both layers are in direct contact with one another. As explained above, embossing can surprisingly be carried out despite interlayer-free application and despite the use of soft scratch-off layers, without sacrificing the quality of the embossing or damaging the scratch-off layer.

Als Rubbelschicht kommen insbesondere opaken Farbschichten in Frage, die vorzugsweise (im Sieb oder im Flexodruck) aufgedruckt werden. Um eine deckende Wirkung zu erhalten und einen entsprechend gut geeigneten Hintergrund für die Lackschicht zu bilden, werden hier bevorzugt latexhaltige Rubbelschichten mit einer Mindest-Schichtdicke von 10 Mikrometern verwendet, besonders bevorzugterweise mit Schichtdicken über 15 Mikrometern.In particular, opaque color layers which are preferably printed (in screen or in flexographic printing) are possible as the scratch-off layer. In order to obtain a covering effect and to form a correspondingly suitable background for the lacquer layer, latex-containing scratch-off layers with a minimum layer thickness of 10 micrometers are preferably used here, particularly preferably with layer thicknesses above 15 micrometers.

Um eine gute Abrubbelbarkeit in Kombination mit dem geprägten Lack zu erreichen, sollte die Rubbeischicht eine Kratzfestigkeit von maximal 4N, gemessen mit dem Erichsen Härteprüfstab (Prüfspitze 0,75 mm) aufweisen. Besonders gut geeignet sind Rubbelschichten mit einer Kratzfestigkeit von maximal 3N, ebenfalls gemessen mit dem Erichsen Härteprüfstab (Prüfspitze 0,75 mm).In order to achieve a good rub-off in combination with the embossed lacquer, the scratch-off layer should have a scratch resistance of a maximum of 4N, measured with the Erichsen hardness test rod (test tip 0.75 mm). Scratch layers with a maximum scratch resistance of 3N, also measured with the Erichsen hardness test rod (test tip 0.75 mm), are particularly suitable.

Als Lackschichten kommen in erster Linie transparente Lacke in Frage. In einer besonders bevorzugten Ausführungsform der Erfindung weist die Lackschicht eine Höchstdicke von 20 Mikrometern auf, um eine hohe Qualität der Hologrammprägung zu ermöglichen.As a paint layers are primarily transparent paints in question. In In a particularly preferred embodiment of the invention, the lacquer layer has a maximum thickness of 20 micrometers in order to enable a high quality of hologram embossing.

In einer besonders bevorzugten Ausführungsform wird die Rubbeloberfläche auf einem Etikett bereitgestellt, d.h. in Verbindung mit einer Basisfolie 104. Auf jeden Fall jedoch weist sie ein Mittel zur Fixierung an einem Objekt auf; in der Regel eine Klebstoffschicht. Wird die Rubbeloberfläche nicht als Etikett, sondern beispielsweise als Transfer-Farbschicht bereitgestellt, so entfällt die Basisfolie 104a, und als Fixierungsmittel dient beispielsweise ein wärmeaktivierbarer Klebstoff.In a particularly preferred embodiment, the scratch-off surface is provided on a label, i. in any case, however, it has a means for fixing to an object; usually an adhesive layer. If the rubbing surface is not provided as a label but as, for example, a transfer ink layer, the base film 104a is omitted, and a heat-activatable adhesive, for example, is used as the fixing agent.

In Fig. 1b ist eine spezielle Ausführungsform einer erfindungsgemäßen Rubbeloberfläche abgebildet. Sie besteht aus drei Funktionsschichten; der Rubbelschicht 105b, der geprägten Lackschicht 109b und einer Beschichtung 111 b zur Verbesserung der Reflexionseigenschaften. Diese zusätzliche Schicht wird auf die geprägte Oberfläche der Lackschicht aufgebracht, um den holographischen Effekt auch dann zu erhalten, wenn die Oberfläche beispielsweise mit Flüssigkeiten oder Fetten in Berührung kommt, etwa Handschweiß. Eine derartige Beschichtung kann beispielsweise eine Metallisierung sein, aber auch andere aufgesprühte, aufgedruckte oder aufgedampfte Substanzen können hierzu dienen.In Fig. 1b a special embodiment of a rubbing surface according to the invention is shown. It consists of three functional layers; the scratching layer 105b, the embossed resist layer 109b and a coating 111b for improving the reflection properties. This additional layer is applied to the embossed surface of the lacquer layer to obtain the holographic effect even when the surface comes into contact with, for example, liquids or fats, such as hand perspiration. Such a coating may for example be a metallization, but other sprayed, printed or vapor-deposited substances can serve this purpose.

Die erfindungsgemäße Rubbeloberfläche kann in einem sehr einfachen Herstellungsverfahren in einem Maschinengang und materialsparend hergestellt werden: Notwendig sind hierzu zwei Druck- bzw. Beschichtungsvorgänge (für die Rubbelschicht und die Lackschicht) und die entsprechenden Trocknungseinrichtungen und danach eine Hologramm-Prägeeinheit. Im Vergleich zum bisher gebräuchlichen Auflaminieren oder Heißsiegeln einer weiteren Folie auf die Rubbelschicht ergibt sich hier nicht nur ein Kostenvorteil, sondern auch ein deutlich vereinfachter Prozeß zur Herstellung eines mindestens gleichwertigen Produkts.The rubbing surface according to the invention can be produced in a very simple production process in a single pass and in a material-saving manner. For this purpose, two printing or coating processes (for the scratch-off layer and the varnish layer) and the corresponding drying devices and then a hologram embossing unit are required. In comparison to the conventional lamination or heat-sealing of another film on the scratch-off layer, not only is this a cost advantage, but also a significantly simplified process for producing an at least equivalent product.
