Description

Die Erfindung betrifft ein Sicherheitsdokument, insbesondere, Banknote, Ausweiskarte oder dergleichen, mit einem Sicherheitselement, welches wenigstens teilweise mit einem magnetischen Material versehen ist, sowie ein Verfahren zur Herstellung des Sicherheitsdokumentes.The invention relates to a security document, in particular a bank note, identity card or the like, with a security element which is at least partially provided with a magnetic material, and a method for producing the security document.

Sicherheitsdokumente mit magnetischen Materialien, die auf oder in dem Dokument angeordnet sind, sind seit langem bekannt. Die magnetischen Materialien können dabei beispielsweise in Form von Streifen aufgebracht oder auf separaten Trägermaterialien angeordnet sein, die wiederum mit dem Dokument fest verbunden werden.Security documents with magnetic materials placed on or in the document have long been known. The magnetic materials can be applied in the form of strips, for example, or can be arranged on separate carrier materials, which in turn are firmly connected to the document.

Ein derartiges Sicherheitsdokument ist beispielsweise aus der DE-PS 16 96 245 bekannt. In dieser Schrift wird ein Verfahren offenbart, bei dem ein geeignetes Trägermaterial, wie z.B. Seide, Baumwolle oder Kunststoff mit einer magnetischen Überzugsmischung versehen und anschließend in ein Sicherheitsdokument eingebettet wird. Das Sicherheitsdokument läßt sich anhand des eingebrachten Sicherheitselementes, insbesondere eines eingebrachten Sicherheitsfadens, maschinell eindeutig identifizieren.Such a security document is known for example from DE-PS 16 96 245. In this document a method is disclosed in which a suitable carrier material, such as e.g. Silk, cotton or plastic are provided with a magnetic coating mixture and then embedded in a security document. The security document can be uniquely identified by machine on the basis of the security element, in particular a security thread.

Aus der DE 41 01 301 ist darüber hinaus ein Sicherheitsdokument bekannt, in welches ein magnetisches Sicherheitselement eingebracht ist, bei dem die magnetische Beschichtung weichmagnetische Pigmente aufweist. Diese hellgrau bis silbrigen Pigmente werden einem geeigneten Firnis beigemischt und zusammen mit diesem auf ein Trägermaterial aufgestrichen und anschließend in das Sicherheitsdokument eingebettet, so daß das eingebrachte magnetische Sicherheitselement im Auflicht kaum in Erscheinung tritt.A security document is also known from DE 41 01 301, in which a magnetic security element is introduced, in which the magnetic coating has soft magnetic pigments. These light gray to silvery pigments are mixed in a suitable varnish and spread together with this on a carrier material and then embedded in the security document so that the magnetic security element introduced hardly appears in reflected light.

Die Prüfung von Sicherheitsdokumenten, die magnetische Sicherheitselemente aufweisen, kann, wie z.B. in der DE 27 54 267 C3 beschrieben, unter anderem so durchgeführt werden, daß die Koerzitivität des Elementes gemessen wird.The examination of security documents that have magnetic security elements can, as for example in DE 27 54 267 C3 described, among other things, be carried out so that the coercivity of the element is measured.

Bislang werden in Sicherheitsdokumenten meist handelsübliche Eisenoxide verwendet, wie sie auch in der Tonband- und Videotechnik Anwendung finden. Hierbei handelt es sich üblicherweise um FE3O4 mit einer Koerzitivität im Bereich von ca. 350 bis 1000 Oe, wobei diese mittlere Koerzitivität eine relativ einfache Magnetisierbarkeit und gleichzeitig eine ausreichende Permanentmagnetisierung gewährleistet. Fälschungen von Sicherheitsdokumenten, die unter Verwendung handelsüblicher Tonbänder den Eindruck eines echten Sicherheitsfadens vortäuschen, sind daher nicht ausgeschlossen.To date, commercially available iron oxides have mostly been used in security documents, as they are also used in tape and video technology. These are usually FE 3 O 4 with a coercivity in the range of approximately 350 to 1000 Oe, this average coercivity ensuring relatively simple magnetizability and, at the same time, adequate permanent magnetization. Counterfeiting of security documents that pretend to be genuine security thread using standard tapes is therefore not excluded.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Sicherheitsdokument und ein Verfahren zu dessen Herstellung vorzuschlagen, das ein magnetisches Material aufweist, dessen magnetische Eigenschaften so ausgebildet sind, daß sie nur schwer nachahmbar sind.The object of the present invention is therefore to propose a security document and a method for its production, which comprises a magnetic material whose magnetic properties are designed in such a way that they are difficult to imitate.

Diese Aufgabe wird erfindungsgemäß durch die in den unabhängigen Ansprüchen genannten Merkmale gelöst.This object is achieved according to the invention by the features mentioned in the independent claims.

Der Grundgedanke der Erfindung besteht darin, als Sicherheitselement einen Träger zu verwenden, der mit einer definierten, niedrigkoerzitiven magnetischen Schicht beschichtet wurde. Wegen der geringen Koerzitivität und der daraus resultierenden raschen Entmagnetisierung auch unter Einfluß schwacher Felder, erlauben derartige magnetische Schichten zwar keine permanente Datenspeicherung, jedoch besitzen sie gegenüber den herkömmlichen mittelkoerzitiven magnetischen Beschichtungen den Vorteil, daß sie im Handel unüblich sind. Da die Koerzitivität eines Materials unabhängig von anderen magnetischen Werten, z.B. der Remanenz, eingestellt werden kann, ist es möglich, die erfindungsgemäßen magnetischen Materialien in das Dokument einzubringen, wobei sich die magnetischen Materialien ausschließlich im Wert der Koerzitivität von den bisher verwendeten unterscheiden. Dies birgt den Vorteil in sich, daß die üblichen Eigenschaften des magnetischen Materials, wie beispielsweise die Remanenz, mit allen bereits vorhandenen Standardsensoren gemessen werden können, während als zusätzlicher Sicherungseffekt die niedrige und bevorzugt definierte Koerzitivität des magnetischen Materials ausschließlich mit Spezialsensoren feststellbar ist. Eine Nachstellung des neuen magnetischen Sicherheitselementes im Dokument wird somit nahezu unmöglich.The basic idea of the invention is to use a carrier as a security element which has been coated with a defined, low-coercive magnetic layer. Because of the low coercivity and the resulting rapid demagnetization even under the influence of weak fields, such magnetic layers do not allow permanent data storage, but they have the advantage over the conventional medium-coercive magnetic coatings that they are unusual in the trade. Because the coercivity of one material is independent of other magnetic Values, for example the remanence, can be set, it is possible to introduce the magnetic materials according to the invention into the document, the magnetic materials differing only in the value of the coercivity from those previously used. This has the advantage that the usual properties of the magnetic material, such as remanence, can be measured with all existing standard sensors, while the low and preferably defined coercivity of the magnetic material can only be determined with special sensors as an additional securing effect. Re-enactment of the new magnetic security element in the document is therefore almost impossible.

Gemäß einer bevorzugten Ausführungsform wird Eisen als magnetisches Material verwendet, das auf einen Träger aufgedampft wird. Die gewünschte Koerzitivität der aufgebrachten Eisenschicht läßt sich unabhängig von ihrer Dicke über die Herstellungsparameter einstellen. Wird die Schicht beispielsweise in mehreren separaten Aufdampfschritten aufgebracht, so wird eine niedrigere Koerzitivität erreicht, als beim kontinuierlichen Aufdampfen der gesamten Schicht gleicher Gesamtdicke. Ferner gilt, je weniger Verunreinigungen im Material enthalten sind, desto geringer ist die Koerzitivität.According to a preferred embodiment, iron is used as the magnetic material, which is evaporated onto a carrier. The desired coercivity of the iron layer applied can be set via the production parameters regardless of its thickness. If, for example, the layer is applied in several separate evaporation steps, a lower coercivity is achieved than with continuous evaporation of the entire layer of the same total thickness. Furthermore, the less impurities the material contains, the lower the coercivity.

Bei ein und derselben Gesamtschichtdicke und dem gleichen magnetischen Material können somit unterschiedliche Koerzitivitäten eingestellt werden. Das Herstellungsverfahren läßt sich alternativ auch so durchführen, daß für unterschiedliche Gesamtschichtdicken gleiche Koerzitivitätswerte erzielt werden.With one and the same total layer thickness and the same magnetic material, different coercivities can thus be set. The production process can alternatively also be carried out in such a way that the same coercivity values are achieved for different total layer thicknesses.

Im Gegensatz zur Koerzitivität sind andere magnetische Eigenschaften, wie z.B. die Remanenz, abhängig von der Menge des aufgebrachten Eisens und weitgehend unabhängig von dem Herstellungsverfahren der Schicht.In contrast to coercivity, other magnetic properties, such as remanence, are largely independent of the amount of iron applied from the manufacturing process of the layer.

Dadurch können Eisenschichten mit gleicher Schichtdicke hergestellt werden, die eine einheitliche Remanenz aufweisen, jedoch unterschiedliche Koerzitivitäten haben. Umgekehrt lassen sich auch Beschichtungen aufbringen, die eine einheitliche Koerzitivität jedoch unterschiedliche Schichtdicken und somit unterschiedliche Remanenzen aufweisen.As a result, iron layers with the same layer thickness can be produced, which have a uniform remanence but have different coercivities. Conversely, coatings can also be applied that have a uniform coercivity but different layer thicknesses and thus different remanences.

Diese Tatsache bringt den Vorteil mit sich, daß der Datenträger mit dem erfindungsgemäßen magnetischen Material zunächst mit Standardsensoren beispielsweise daraufhin untersucht werden kann, ob magnetische Materialien im Datenträger vorhanden sind, welche eine hinreichend große Remanenz aufweisen. Im Anschluß daran läßt sich überprüfen, ob das magnetische Material den für die Echtheitserkennung erforderlichen Koerzitivitätswert aufweist.This fact has the advantage that the data carrier with the magnetic material according to the invention can first be examined with standard sensors, for example, to determine whether there are magnetic materials in the data carrier which have a sufficiently large remanence. It can then be checked whether the magnetic material has the coercivity value required for authenticity detection.

Alternativ ist es auch im Sinne der Erfindung, kristalline, pulverförmige niedrigkoerzitive Materialien zu verwenden, die in ein Bindemittel eingemischt und verdruckt werden können.Alternatively, it is also within the meaning of the invention to use crystalline, powdery, low-coercive materials which can be mixed into a binder and printed.

Fig. 1 zeigt eine Banknote 1 mit einem eingelagerten Sicherheitsfaden gemäß der Erfindung. Der Faden ist vollständig in das Papierinnere eingebettet, was durch die gestrichelte Linie angedeutet wird. Es ist jedoch ebenso möglich, den Faden in Teilbereichen oder vollständig an die Oberfläche der Banknote treten zu lassen, so daß ein sogenannter Fenstersicherheitsfaden entsteht. Darüber hinaus läßt sich das Sicherheitselement in das Wertdokument auch in Form von Planchetten oder Melierfasern an bestimmten Stellen des Sicherheitsdokumentes einbringen.1 shows a bank note 1 with an embedded security thread according to the invention. The thread is completely embedded in the paper interior, which is indicated by the dashed line. However, it is also possible to let the thread come to the surface of the banknote in parts or completely, so that a so-called window security thread is created. In addition, the security element can also be incorporated into the value document in the form of planchettes or mottled fibers at certain points in the security document.

Der erfindungsgemäße Sicherheitsfaden ist im Querschnitt entlang der Schnittlinie A - B in Fig. 2 dargestellt. Hierbei ist auf einem Träger 3, der üblicherweise aus einem Kunststoffmaterial besteht, eine magnetisierbare Eisenschicht 4 aufgebracht, die eine Koerzitivität von 100 Oe aufweist. Die magnetisierbare Schicht 4 kann jedoch auch aus Nickel oder einer magnetischen Legierung bestehen. Einzige Bedingung ist, daß die Koerzitivität der Schicht zwischen ca. 10 und ca. 250, bevorzugt zwischen 20 und 150 Oe liegt. Die Dicke der magnetisierbaren Schicht hat im wesentlichen keinen Einfluß auf die Koerzitivität und läßt sich bei üblicher Wahl der Verfahrensparameter zwischen 0,05 und 1 µm einstellen.The security thread according to the invention is shown in cross section along the section line A - B in FIG. 2. Here, a magnetizable iron layer 4, which has a coercivity of 100 Oe, is applied to a carrier 3, which usually consists of a plastic material. However, the magnetizable layer 4 can also consist of nickel or a magnetic alloy. The only condition is that the coercivity of the layer is between approximately 10 and approximately 250, preferably between 20 and 150 Oe. The thickness of the magnetizable layer has essentially no influence on the coercivity and can be set between 0.05 and 1 μm with the usual choice of process parameters.

Entsprechend den aufgebrachten Schichtdicken und je nach verwendetem Material werden bei dieser Vorgehensweise Remanenzen eingestellt, deren Werte bevorzugt zwischen 100 und 1000 nWb/m liegen.According to the applied layer thicknesses and depending on the material used in this procedure Retentions are set, the values of which are preferably between 100 and 1000 nWb / m.

Zur Herstellung des erfindungsgemäßen Sicherheitsfadens wird das magnetisierbare Material, beispielsweise Eisen, in mehreren Arbeitsgängen in Einzelschichten aufgedampft, so daß die Schichtdicke der magnetisierbaren Gesamtschicht 0,1 µm beträgt. Durch das Aufdampfen der Schicht in mehreren separaten Arbeitsgängen wird eine Koerzitivität von ca. 20 Oe erreicht. Die Remanenz liegt hierbei bei etwa 150 nWb/m. Alternativ läßt sich die Koerzitivität durch eine Änderung der Verfahrensparameter bei gleicher Schichtdicke ändern, wobei auch die Remanenz jedoch gleich bleibt. Hierzu wird die magnetisierbare Schicht in der Schichtdicke von 0,1 µm in einem einzigen Arbeitsgang aufgedampft, was zu einer Koerzitivität von 100 Oe und einer Remanenz von 150 nWb/m führt. Die gleiche Koerzitivität von 100 Oe mit höherer Remanenz läßt sich dadurch herstellen, daß die Schichtdicke auf 0,2 µm erhöht wird und das Aufdampfen wiederum in einem einzigen Arbeitsgang erfolgt, denn die Änderung der Schichtdicke beeinflußt die Koerzitivität im wesentlichen nicht. Die Remanenz hingegen steigt dabei auf einen Wert von ca. 300 nWb/m. Auf diese Weise lassen sich also gezielt Schichten herstellen, die als gemeinsame Eigenschaft eine einheitliche Koerzitivität bei unterschiedlicher Schichtdicke aufweisen, während andere magnetische Eigenschaften, wie etwa die Remanenz, für jede Schichtdicke verschieden sind.To produce the security thread according to the invention, the magnetizable material, for example iron, is vapor-deposited in individual layers in a plurality of work steps, so that the layer thickness of the total magnetizable layer is 0.1 μm. By evaporation of the layer in several separate operations, a coercivity of approx. 20 Oe is achieved. The remanence is about 150 nWb / m. Alternatively, the coercivity can be changed by changing the process parameters with the same layer thickness, but the remanence also remains the same. For this purpose, the magnetizable layer with a thickness of 0.1 µm is evaporated in a single operation, which leads to a coercivity of 100 Oe and a remanence of 150 nWb / m. The same coercivity of 100 Oe with higher remanence can be achieved by increasing the layer thickness to 0.2 µm and again applying the vapor deposition in a single operation, since the change in the layer thickness does not essentially affect the coercivity. The remanence, however, increases to a value of approx. 300 nWb / m. In this way, layers can be specifically produced which, as a common property, have uniform coercivity with different layer thicknesses, while other magnetic properties, such as remanence, are different for each layer thickness.

Das magnetische Material läßt sich beispielsweise durch eine widerstandsbeheizte Verdampfung von Reineisen aufbringen. Die Schichten lassen sich jedoch auch durch anodische Lichtbogenverdampfung oder Elektronenstrahlverdampfung herstellen. Ebenso ist es möglich, ein verdruckbares magnetisches Material zu verwenden, das eine entsprechend geringe Koerzitivität aufweist.The magnetic material can be applied, for example, by resistance-heated evaporation of pure iron. However, the layers can also be produced by anodic arc evaporation or electron beam evaporation. It is also possible to use a printable magnetic material that has a correspondingly low coercivity.

Informationen, wie Bilder, Logos oder Schriftzüge, lassen sich durch allgemein übliche Verfahren in das Sicherheitselement einbringen. Diese können beispielsweise dadurch erzeugt werden, daß die Anlagerung der magnetischen Schicht in Teilbereichen verhindert wird oder die magnetische Schicht nach dem Aufbringen gezielt entfernt wird, so daß beispielsweise der in Fig. 3 gezeigte Faden, der mit dem Schriftzug PL versehen wurde, hergestellt werden kann. Die Schriftzeichen 6 werden hierbei z.B. durch lokales Entfernen der magnetisierbaren Eisenschicht mit Hilfe eines Laserstrahls erzeugt. Selbstverständlich können jedoch auch andere Verfahren benutzt werden, mit denen die Negativschriftzeichen in den Faden eingebettet werden, wie z.B. die in der EP 516 790 beschriebenen Verfahren.Information, such as pictures, logos or lettering, can be introduced into the security element using standard procedures. These can be produced, for example, by preventing the magnetic layer from accumulating in partial areas or by deliberately removing the magnetic layer after application, so that, for example, the thread shown in FIG. 3, which has been provided with the lettering PL, can be produced . The characters 6 are e.g. generated by local removal of the magnetizable iron layer with the aid of a laser beam. Of course, other methods can also be used with which the negative characters are embedded in the thread, e.g. the methods described in EP 516 790.

Um das optische Erscheinungsbild des Fadens weiter zu verbessern, kann, wie in Fig. 4 gezeigt, über der magnetisierbaren Schicht 4 eine dünne Metallschicht 5 aufgebracht werden. In diesem Zusammenhang ist auch die Verwendung von farbigen Metallschichten möglich, welche das Erscheinungsbild des Fadens weiterhin verbessert. Die zusätzliche Metallschicht, die beispielsweise aus Aluminium besteht, kann vor dem Einbringen der Zeichen 6 auf die magnetische Schicht 4 aufgebracht werden, so daß beim Einbringen der Zeichen auch die Metallschicht 5 in diesem Bereich vollständig entfernt wird.In order to further improve the optical appearance of the thread, a thin metal layer 5 can be applied over the magnetizable layer 4, as shown in FIG. 4. In this context, the use of colored metal layers is also possible, which further improves the appearance of the thread. The additional metal layer, which consists for example of aluminum, can be applied to the magnetic layer 4 before the characters 6 are introduced, so that the metal layer 5 in this area is also completely removed when the characters are introduced.

In Fig. 5 ist eine weitere Ausführungsform des erfindungsgemäßen Sicherheitselementes gezeigt. Hierbei wird auf einen Träger 3 zunächst eine Metallschicht 5 aufgetragen, auf welche in einem weiteren Arbeitsgang die magnetisierbare Schicht mit geringer Koerzitivität aufgetragen wird. Zusätzlich wird auf die magnetische Schicht 4 eine weitere metallische Schicht 7 aufgebracht. Die Verwendung zweier dünner Metallschichten erscheint immer dann geboten, wenn der Faden im Papier im Auf- und Durchlicht ein einheitliches Erscheinungsbild zeigen soll. Durch diese Maßnahme wird die magnetische Schicht von beiden Seiten her abgedeckt, und die eingebrachten Zeichen erscheinen von beiden Seiten deutlich als höhertransparente Bereiche.5 shows a further embodiment of the security element according to the invention. In this case, a metal layer 5 is first applied to a carrier 3, to which the magnetizable layer with low coercivity is applied in a further operation. In addition, a further metallic layer 7 is applied to the magnetic layer 4. The use of two thin layers of metal always appears necessary when the thread is in the paper should show a uniform appearance in reflected and transmitted light. As a result of this measure, the magnetic layer is covered from both sides, and the characters introduced appear clearly from both sides as more transparent areas.

Durch die Verwendung unterschiedlicher metallischer Materialien für die Abdeckung des magnetischen Materials lassen sich zusätzlich farbliche Effekte erzeugen, die dem Sicherheitselement neben seiner nun durchgehenden Leitfähigkeit ein optisch prüfbares Sicherheitsmerkmal verleihen. So lassen sich z. B. durch die Verwendung von Cu-Legierungen Goldtöne erzeugen. Ähnliche Farbeffekte lassen sich selbstverständlich durch das Aufbringen von farbigen durchscheinenden Lackschichten auf Aluminium erzeugen.By using different metallic materials to cover the magnetic material, additional color effects can be created which, in addition to its now continuous conductivity, give the security element an optically verifiable security feature. So z. B. generate gold tones by using Cu alloys. Similar color effects can of course be created by applying colored, translucent lacquer layers on aluminum.

Die oben bereits beschriebenen, in den Sicherheitsfaden eingebrachten Informationen können in Positiv- oder Negativform vorliegen. Selbstverständlich lassen sich die Informationen auch durch geeignete Druckverfahren, wie etwa dem Mikrodruck, sowohl auf die Oberfläche der metallischen Schicht 5 oder 7 wie auch auf die Oberfläche der magnetisierbaren Schicht 4 aufbringen.The information already introduced above and included in the security thread can be in a positive or negative form. Of course, the information can also be applied to the surface of the metallic layer 5 or 7 as well as to the surface of the magnetizable layer 4 by means of suitable printing methods, such as microprinting.

Die Zahl der Varianten, mit denen Schriftzeichen, Bilder oder Logos in einen magnetischen Faden eingebracht werden können, sind groß und wurden bereits in der EP 516 790 beschrieben. Die dort angegebenen Verfahrensvarianten sind entsprechend auch beim erfindungsgemäßen Datenträger anwendbar.The number of variants with which characters, pictures or logos can be introduced into a magnetic thread are large and have already been described in EP 516 790. The method variants specified there can also be used accordingly in the data carrier according to the invention.

Um das Sicherheitsdokument mit dem ein- oder aufgebrachten Sicherheitselement auf seine Authentizität hin zu prüfen, wird das Sicherheitspapier in ein Prüfgerät eingeführt. Bei der Prüfung des Dokumentes an sich kann zunächst das Sicherheitsdokument dahingehend untersucht werden, ob ein magnetisierbares Sicherheitselement vorliegt. Hierzu kann zunächst eine beliebige magnetische Eigenschaft ermittelt werden, wobei z.B. die Remanenz gemessen wird. Diese sollte einen Mindestwert aufweisen, der über den Remanenzwerten von Druckfarben liegt, die üblicherweise auf dem Datenträger verwendet werden. Solche Remanenzwerte sind bevorzugt über 100 nWb/m angesiedelt. Sofern dieser Test positiv ausfällt, wird das Sicherheitselement einem weiteren Test unterzogen, bei dem geprüft wird, ob ein bestimmter Koerzitivitätswert meßbar ist. Durch einen Vergleich des gemessenen Koerzitivitätswertes mit einem für dieses Dokument spezifischen kann die Echtheit des Dokumentes nachgewiesen werden. Selbstverständlich ist die Durchführung des ersten Schrittes nicht zwingend erforderlich, um das Dokument prüfen zu können. Wesentlich bei dem jeweils angewendeten Verfahren ist lediglich die sichere Ermittlung des Koerzitivitätswertes des Sicherheitselementes, wobei nicht einmal zwingend ein Vergleich mit etwaigen gespeicherten Werten erfolgen muß. Dies ist insbesondere immer dann der Fall, wenn ohnehin klar ist, welcher Koerzitivitätswert bei der Messung die Echtheit des Dokumentes nachweist.In order to check the authenticity of the security document with the security element inserted or applied, the security paper is introduced into a testing device. When checking the document itself, the security document can first be examined for this whether there is a magnetizable security element. For this purpose, any magnetic property can first be determined, for example the remanence is measured. This should have a minimum value that is higher than the retentive values of printing inks that are usually used on the data carrier. Such retentive values are preferably above 100 nWb / m. If this test is positive, the security element is subjected to a further test in which it is checked whether a specific coercivity value can be measured. The authenticity of the document can be verified by comparing the measured coercivity value with a specific value for this document. Of course, the first step is not absolutely necessary to be able to check the document. What is essential in the method used in each case is merely the reliable determination of the coercivity value of the security element, it not even being necessary to compare it with any stored values. This is always the case when it is already clear which coercivity value proves the authenticity of the document during the measurement.
