Abstract

Die Erfindung betrifft eine Identifikationskart (10) aus mehreren Schichten (1,2,3,4), von denen die Abdeckschichten (1,2) aus stark transparenten Follien und die Schichten (3,4) des Kartenkerns aus Folien von mittlerer bis schwacher Transparenz bestehen. Die Schichten (3,4) sind durch Pigmentzusatz matt eingefärbt. Die Schicht (3) trägt direkt lesbare Informationen, gegebenenfalls über einem Sicherheitsdruck, während die Schicht (4) ein zusätzliches Sicherungsmerkmal (6), wie einen Guilloche-Druck, ein optisch nur mit Hilfe einer Lampe auslesbares Merkmal oder ein Stück eines Magnetbandes aufweist.The invention relates to an identification card (10) comprising a plurality of layers (1, 2, 3, 4), of which the cover layers (1, 2) made of highly transparent follies and the layers (3, 4) of the card core made of films of medium to weaker There is transparency. The layers (3,4) are colored matt by the addition of pigment. The layer (3) carries directly readable information, possibly via a security print, while the layer (4) has an additional security feature (6), such as a guilloche print, a feature that can only be read optically with the aid of a lamp, or a piece of magnetic tape.

Alle Schichten bestehen aus miteinander verschmelzbaren Polymeren, beispielsweise Polyamiden, Polyvinylchlorid oder dgl., die nach dem Kaschieren unter einem Druck von 9.8 bis 20 bar bei Temperaturen von 353° bis 452°K einen zu einem Block verschmolzenen Verbund bilden, der keine eine mechanische, thermische oder chemische Auftrennung begünstigenden Zwischenflächen auf weist.All layers consist of fusible polymers, for example polyamides, polyvinyl chloride or the like. After lamination under a pressure of 9.8 to 20 bar at temperatures of 353 ° to 452 ° K, they form a composite fused into a block that does not have a mechanical, thermal or chemical separation favoring interfaces.

Description

Die Erfindung betrifft eine Identifikationskarte aus mehreren Schichten, mit der Identifizierung des Karteninhabers dienenden Informationen an geeigneter Stelle und mit zusätzlichen Sicherungsmerkmalen, wie Guilloche-Figuren, gegen Fälschungen.The invention relates to an identification card of several layers, serving with the identification of the cardholder information in a suitable place and g smerkmalen with additional Sicherun as guilloche figures, against counterfeiting.

Derartige Karten werden als Informations- bzw. Datenträger für Identifikationskarten, Scheckkarten, Kreditkarten, Personalausweise, Pässe und sonstige Identifikationsträger verwendet, die fälschungssicher und leicht auf Echtheit überprüfbar sein müssen.Cards of this type are used as information or data carriers for identification cards, check cards, credit cards, identity cards, passports and other identification carriers which must be tamper-proof and easy to check for authenticity.

Im zunehmenden Maß werden derartige Identifikationskarten als verschmolzener Verbund hergestellt, bei dem ein die Informationen tragender Kartenkern durch andere transparente Folien geschützt wird. So betrifft die DE-OS 23 08 876 eine Identifikationskarte aus einer relativ dicken Trägerfolie und einer dünnen Klarsichtfolie, zwischen denen sich ein Spezialpapier mit der Fälschungssicherung dienenden, Dickenunterschiede des Papiers hervorrufenden Einlagerungen, wie Wasserzeichen, Banknotendruck oder dgl., befindet, wobei die drei Schichten so miteinander plastifiziert sind, daß die Einlagerungen durch die Klarsichtfolie manuell, mechanisch und/oder visuell feststellbar sind. Weitere, der Identifizierung des Karteninhabers dienende Markmale sind bei dieser bekannten Identifikationskarte an geeigneter Stelle vorgesehen. Beim Plastifizieren wird beispielsweise ein Foto in Form eines Filmdiapositivs zwischen dem Spezialpapier und der Trägerfolie eingebracht und fest mit dem Spezialpapier verbunden. Des weiteren kann an beliebiger Stelle der Vorder- oder Rückseite der Identifikationskarte ein sicherungstechnisch bedruckter Spezialpapierstreifen außen auf dem Plastikmaterial als Feld für nachträgliche Unterschriften oder sonstige handschriftliche Eintragungen aufkaschiert werden.Such identification cards are increasingly being produced as a fused composite, in which a card core carrying the information is protected by other transparent foils. For example, DE-OS 23 08 876 relates to an identification card made of a relatively thick carrier film and a thin transparent film, between which there is a special paper with anti-counterfeiting, thickness differences in the paper, such as watermarks, banknote printing or the like, the three Layers are plasticized with one another in such a way that the inclusions can be determined manually, mechanically and / or visually through the transparent film. Further features serving to identify the cardholder are provided at a suitable location in this known identification card. When plasticizing For example, a photo in the form of a film slide is inserted between the special paper and the carrier film and firmly connected to the special paper. Furthermore, a security-printed special paper strip can be laminated on the outside of the plastic material as a field for subsequent signatures or other handwritten entries at any point on the front or back of the identification card.

Papier weist den Vorteil auf, daß viele latente Sicherheitsmerkmale, wie Wasserzeichen, Banknotendruck, Sicherheitsfäden und dgl., in ihm enthalten sein können, während demgegenüber das für die Herstellung von Plastikkarten verwendete Vollkunststoff-Material keinerlei derartige Echtheits- bzw. Sicherungsmerkmale enthält. Bei Verbunden mit Papierkernen ist bedauerlicherweise von Nachteil, daß diese relativ leicht zu öffnen sind und damit Manipulationen und Fälschungen jeder Art zugänglich sind.Paper has the advantage that many latent security features, such as watermarks, banknote printing, security threads and the like, can be contained therein, whereas the all-plastic material used for the production of plastic cards does not contain any such authenticity or security features. When connected to paper cores it is unfortunately disadvantageous that they are relatively easy to open and thus manipulations and counterfeits of all kinds are accessible.

Aus der DE-AS 21 63 943 ist eine Personenidentifikationskarte bekannt, die eine Kombination eines Schichtträgers, einer elektrisch leitenden Schicht, einer Sperrschicht, einer fotoleitfähigen Schicht mit einem organischen Fotoleiter - gegebenenfalls einer Abdeckschicht -, einer Schutzschicht auf der fotoleitfähigen Schicht oder auf der Abdeckschicht, einer Schutzschicht auf der Rückseite des Schichtträgers und gegebenenfalls einer Abdeckschicht auf der letztgenannten Schutzschicht umfaßt. Bei dieser Personenidentifikationskarte'wird eine Anzahl von unterschiedlichen Materialien zu einem Verbund zusammengefügt, der wegen der fehlenden Homogenität der einzelnen Schichten auflösbar ist, so daß Fälschungen vorgenommen werden können.From DE-AS 21 63 943 a personal identification card is known which is a combination of a layer support, an electrically conductive layer, a barrier layer, a photoconductive layer with an organic photoconductor - optionally a cover layer -, a protective layer on the photoconductive layer or on the cover layer , a protective layer on the back of the support and optionally a cover layer on the latter protective layer. This personal identification card has a number of under Different materials put together to form a composite that can be resolved due to the lack of homogeneity of the individual layers, so that counterfeits can be made.

Aufgabe der Erfindung ist es, eine Identifikationskarte aus einem Verbund von Schichten zu schaffen, die dem Versuch eines Auftrennens in einzelne Schichten und somit Fälschungseingriffen an den auf den Schichten angebrachten Informationen und Sicherungsmerkmalen widerstehen.The object of the invention is to create an identification card from a combination of layers which resist the attempt to separate it into individual layers and thus counterfeit tampering with the information and security features attached to the layers.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

In Ausgestaltung der Erfindung ist der Kartenkern aus mindestens zwei Schichten zusammengesetzt, von denen die eine Schicht die direkt der Identifikation dienenden Informationen, wie Name, Lichtbild, Personalnummer und die andere Schicht zusätzliche latente Sicherungsmerkmale trägt. Die einzelnen Schichten der Identitätskarte besitzen unterschiedliche Transparenz, so ist beispielsweise eine der beiden Schichten des Kartenkerns durch Pigmentzusatz matt eingefärbt, bevorzugt weiß, und hat eine mittlere bis schwache Transparenz. Demgegenüber weisen die obere und die untere Abdeckschicht der Identifikationskarte sehr große Transparenz auf.In an embodiment of the invention, the card core is composed of at least two layers, of which one layer carries the information directly used for identification, such as name, photograph, personnel number and the other layer additional latent security features. The individual layers of the identity card have different transparency, for example one of the two layers of the card core is colored matt by pigment addition, preferably white, and has a medium to weak transparency. In contrast, the upper and lower cover layers of the identification card are very transparent.

In weiterer Ausgestaltung der Erfindung besteht der Kartenkern aus drei Schichten, von denen die transparente Zwischenschicht auf zumindest einer Seite von einer der mattierten Schichten eingefaßt ist. Dabei ist die Zwischenschicht mit latenten Sicherungsmerkmalen versehen, die zueinander einen Abstand gleich der Dicke der Zwischenschicht aufweisen. Als zusätzliche Sicherung kommt bei der Identifikationskarte hinzu, daß die Informationen bzw. Sicherungsmerkmale der Schichten des Kartenkerns eine festgelegte, gegenseitige räumliche Zuordnung besitzen.In a further embodiment of the invention, the card core consists of three layers, the transparent of which te intermediate layer is bordered on at least one side by one of the matted layers. The intermediate layer is provided with latent security features that are spaced apart from one another by the thickness of the intermediate layer. As an additional security for the identification card, the information or security features of the layers of the card core have a fixed, mutual spatial assignment.

Es ist auch möglich, daß die Abdeckschichten mit Sicherungsmerkmalen versehen sind und daß die Sicherungsmerkmale zwischen dem Kartenkern und den Abdeckschichten in vorgegebener räumlicher Anordnung zueinander stehen. Zur Vergrößerung der Fälschungssicherheit sind die Informationen und die Sicherungsmerkmale verschiedenfarbig.It is also possible that the cover layers are provided with security features and that the security features between the card core and the cover layers are in a predetermined spatial arrangement to one another. To increase the security against counterfeiting, the information and security features are different colors.

Es liegt auf der Hand, daß der Versuch, eine Identifikationskarte, bei der der Kartenkern und die obere und die untere Abdeckschicht aus thermisch miteinander zu einem Verbund verschmolzenen Polymeren bestehen, zum Zweck der Fälschung der zwischen den Schichten vorhandenen Informationen aufzutrennen, wegen der Homogenität der einzelnen Materialschichten unmöglich ist.It is obvious that the attempt to separate an identification card, in which the card core and the upper and lower cover layers consist of polymers thermally fused together, for the purpose of falsifying the information present between the layers, because of the homogeneity of the individual layers of material is impossible.

Die Erfindung wird im folgenden anhand von zwei in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 in Explosionsdarstellung eine Identifikationskarte mit schematisch angedeuteten Informationen und einem Sicherungsmerkmal,
  • Fig. 2 eine Schnittansicht der Identifikationskarte nach Fig. 1,
  • Fig. 3 eine perspektivische Teilansicht einer weiteren Ausführungsform einer Identifikationskarte, und
  • Fig. 4 eine Schnittansicht der Identifikationskarte nach Fig. 3.
The invention is explained in more detail below with reference to two exemplary embodiments shown in the drawings. Show it:
  • 1 is an exploded view of an identification card with schematically indicated information and a security feature,
  • 2 is a sectional view of the identification card of FIG. 1,
  • 3 is a partial perspective view of a further embodiment of an identification card, and
  • FIG. 4 shows a sectional view of the identification card according to FIG. 3.

Ein Aufbau einer Identifikationskarte ist in Fig. 1 dargestellt. Die Abdeckschichten 1 und 2 aus stark transparenten Folien schließen einen Kartenkern ein und bestehen aus verschmelzbaren Polymeren, beispielsweise Polyamiden, Polyvinylchlorid oder dgl. Der Kartenkern umfaßt zwei Schichten 3 und 4 mittlerer bis schwacher Transparenz. Es handelt sich hierbei gleichfalls um Folien aus verschmelzbaren Polymeren. Die Schichten 3 und 4 sind durch Pigmentzusatz matt, bevorzugt weiß, eingefärbt. Die Schicht 3 trägt direkt lesbare Informationen 5 wie Namen, Personalnummer und Lichtbild des Karteninhabers, die gegebenenfalls über einem Sicherheitsdruck aufgebracht sind. Zumindest eine Schicht, in Fig. 1 die Schicht 4, trägt ein zusätzliches latentes Sicherungsmerkmal 6, das in Fig. 1 durch ein X angedeutet ist. Die Schicht 4 kann auch noch auf der äußeren Seite, die der Abdeckschicht 2 zugewandt ist, bedruckt sein.A structure of an identification card is shown in Fig. 1. The cover layers 1 and 2 made of highly transparent films enclose a card core and consist of fusible polymers, for example polyamides, polyvinyl chloride or the like. The card core comprises two layers 3 and 4 of medium to weak transparency. These are also films made of fusible polymers. Layers 3 and 4 are colored matt, preferably white, by adding pigment. Layer 3 bears directly readable information 5, such as the name, personnel number and photo of the cardholder, which are possibly applied over a security print. At least one layer, layer 4 in FIG. 1, carries an additional latent security feature 6, which is indicated by an X in FIG. 1. The layer 4 can also be printed on the outer side facing the cover layer 2.

Das zusätzliche Sicherungsmerkmal 6 kann beispielsweise ein Magnetband sein, jedoch wird wegen der leichten, ohne großen Aufwand an Hilfsmitteln durchzuführenden Prüfung, ein optisch erkennbares Sicherungsmerkmal bevorzugt. Sc kann es ein unveränderliches, in der Regel schwer nachzuahmendes Merkmal sein, beispielsweise ein Guilloche-Druck oder ein Symbol wie ein Wappentier. Das Merkmal kann durch Druck oder einen Fotokopierprozess aufgebracht werden und auch individuelle Angaben enthalten, beispielsweise eine fortlaufende Nummer oder ein zweites Bild des Karteninhabers.The additional security feature 6 can be, for example, a magnetic tape, but an optically recognizable security feature is preferred because of the easy check that can be carried out without a lot of aids. Sc can be an invariable, usually difficult to follow imitative feature, for example a guilloche print or a symbol such as a heraldic animal. The feature can be applied by printing or a photocopying process and can also contain individual information, for example a consecutive number or a second picture of the cardholder.

Unter den Begriff "optisches" Sicherungsmerkmal sollen auch alle Ausführungsformen fallen, bei denen Materialien für die Herstellung des Sicherungsmerkmals 6 verwendet werden, die nur bei Einstrahlung von ultraviolettem Licht fluoreszieren oder die nur im ultravioletten oder infraroten Licht absorbieren und daher im sichtbaren Bereich nicht erkennbar sind. Diese inneren Sicherungsmerkmale sind bei rein visueller Kartenbetrachtung im reflektierten Licht, z.B. zur Feststellung der Personalien, nicht sichtbar. Für die Prüfung derartiger Sicherungsmerkmale ist dann als einziges Hilfsmittel eine Lampe erforderlich, die eine Ultraviolett- oder Infrarot-Strahlung abgibt, so daß beim Durchleuchten der Identifikationskarte mit einer derartigen Lampe das Sicherungsmerkmal erkennbar wird.The term “optical” security feature should also include all embodiments in which materials are used for the production of the security feature 6 that fluoresce only when irradiated by ultraviolet light or that absorb only in ultraviolet or infrared light and are therefore not recognizable in the visible range . These internal security features are in the case of purely visual map viewing in reflected light, e.g. to determine the personal details, not visible. A lamp that emits ultraviolet or infrared radiation is then the only tool required for testing such security features, so that the security feature can be recognized when the identification card is illuminated with such a lamp.

Die Abdeckschichten 1,2 und die Schichten 3,4 des Kartenkerns bieten nach dem Kaschieren unter einem Druck von 9,8 bis 20 bar (10 - 20 Kp/cm2) bei erhöhten Temperaturen von 353° bis 452° K (80-1800 C) einen als Block verschmolzenen Verbund, der keine eine Trennung begünstigende Zwischenflächen aufweist. Das Sicherungsmerkmal 6, beispielsweise aus Pigmenten, ist dann in die Polymer-Masse des Verbunds eingeschmolzen.The covering layers 1, 2 and layers 3, 4 of the card core offer, after lamination, under a pressure of 9.8 to 20 bar (10 - 20 Kp / cm 2 ) at elevated temperatures of 353 ° to 452 ° K (80-180 0 C) a composite fused as a block, which has no intermediate surfaces which favor separation. The security feature 6, for example made of pigments, is then in the Polymer mass of the composite melted down.

Fig. 2 gibt einen Querschnitt durch diesen Verbund wieder, wobei durch die Schraffur des Kartenkerns, die keine Grenzlinien zu den Abdeckschichten 1,2 zeigt, angedeutet wird, daß ein Verbund der mattierten Schichten ohne Zwischenflächen vorliegt. Der zu verschmelzende Kartenkern kann zur weiteren Sicherheitserhöhung mehr als zwei Schichten aufweisen, die stark transparent sind und innen mit mehreren latenten Sicherungsmerkmalen versehen sein können.Fig. 2 shows a cross section through this composite, the hatching of the card core, which shows no boundary lines to the cover layers 1,2, indicates that there is a composite of the matted layers without intermediate surfaces. To further increase security, the card core to be fused can have more than two layers that are highly transparent and can be provided with several latent security features on the inside.

Die in den Fig. 3 und 4 dargestellte Identifikationskarte 10' umfaßt einen Kartenkern mit einer zusätzlichen transparenten Zwischenschicht 7 mit latenten Sicherungsmerkmalen 8 und 9. Die transparente Zwischenschicht 7 aus einem verschmelzbaren Polymer wie Polyamid, Polyvinylchlorid oder dgl. ist von den mattierten Schichten 3 und 4 an beiden Seitenflächen eingefaßt. Der Schichtwechsel im Aufbau des Kartenkerns zwischen matten und transparenten Schichten hat neben der sicherungstechnischen Anordnung hinaus praktische Bedeutung für die Lesbarkeit der Sicherungsmerkmale 8 und 9. Wäre nämlich der Kartenkern durchgehend mattiert, so hätte er beispielsweise bei einer Dicke von 500 /um nur eine Transmission von einigen Prozenten, wodurch die Lesbarkeit der eingebrachten latenten Sicherungsmerkmale sehr erschwert wäre. Besteht der Kartenkern dagegen außen aus matten Schichten 3 und 4 von beispielsweise je 100 /um Dicke und aus einer transparenten Zwischenschicht 7 von beispielsweise 80 % Transmissionsvermögen bei einer Dicke von 300 /um, so ist eine gute Lesbarkeit der eingebrachten latenten Sicherungsmerkmale 8 und 9 gegeben. Die Lesbarkeit kleiner Strukturen, beispielsweise bei Guilloche-Drucken, nimmt mit dünner werdenden äußeren matten Schichten 3 und 4 oder schwächer pigmentierten äußeren Schichten 3 und 4 des Kartenkerns zu.The identification card 10 'shown in FIGS. 3 and 4 comprises a card core with an additional transparent intermediate layer 7 with latent security features 8 and 9. The transparent intermediate layer 7 made of a fusible polymer such as polyamide, polyvinyl chloride or the like is from the matted layers 3 and 4 edged on both sides. The shift changes in the structure of the card core between matt and transparent layers in addition to the backup technical arrangement addition, namely the card core frosted practical importance for the readability of the security features 8 and 9. If continuously, he would have, for example, at a thickness of 500 / just a transmission of a few percent, which would make it very difficult to read the latent security features. However, there is the card core outside of matte layers 3 and 4 of example 100 / um thickness and made of a transparent intermediate layer 7 of at for example 80% transmittance with a thickness of 300 / um, so the latent security features 8 and 9 are legible. The legibility of small structures, for example in guilloche prints, increases as the outer matt layers 3 and 4 or the less pigmented outer layers 3 and 4 of the card core become thinner.

Der Aufbau des Kartenkerns aus zwei oder mehreren Schichten bietet als zusätzliches, sehr empfindliches Sicherungsmerkmal die gegenseitige räumliche Zuordnung der verschiedenen äußeren und inneren Informationen bzw. Sicherungsmerkmale, wie dies beispielsweise anhand von Fig. 3 kurz erläutert wird. Bestehen die Sicherungsmerkmale 8 und 9 aus deckungsgleich angeordneten Guilloche-Figuren, so ist ein Fälschungsversuch an der Identitätskarte mit Hilfe von Wärme oder Lösungsmitteln zum Auftrennendes Kartenverbunds sofort erkennbar, da es zu einer vollständigen oder teilweisen Verschiebung der Guilloche-Figuren relativ zueinander , eventuell als Moiré-Muster, kommt.The construction of the card core from two or more layers offers, as an additional, very sensitive security feature, the mutual spatial assignment of the various external and internal information or security features, as is briefly explained, for example, with reference to FIG. 3. If the security features 8 and 9 consist of congruently arranged guilloche figures, a forgery attempt on the identity card with the help of heat or solvents to separate the card network is immediately recognizable, since it leads to a complete or partial displacement of the guilloche figures relative to one another, possibly as moiré Pattern is coming.

In Fig. 3 ist eine gegenüber der Guilloche-Figur 8 durch Manipulationen verschobene Guilloche-Figur 9 angedeutet, wobei der punktierte Linienzug der Guilloche-Figur 9 deren ursprüngliche Lage kennzeichnet. Zur besseren Unterscheidbarkeit können die Informationen und das Sicherungsmuster bzw. Sicherungsmerkmale verschiedenfarbig sein.FIG. 3 shows a guilloche figure 9 that has been displaced in relation to the guilloche figure 8 by manipulations, the dotted line of the guilloche figure 9 characterizing its original position. For better differentiability, the information and the security pattern or security features can be of different colors.

Die exakte räumliche Zuordnung von Informationen und Sicherungsmerkmalen im Kartenverbund bei ursprünglich getrennten Schichten erfordert eine ausgereifte Kaschiertechnik mit Paßvorrichtungen wie Paßstiften und Paßlöchern in den einzelnen Schichten und stellt damit eine weitere Sicherung gegen Fälschungen dar. Die räumliche Zuordnung von zwei Guilloche-Figuren kann auch durch doppelseitigen, paßgenauen Druck auf der Zwischenschicht 7 erfolgen.The exact spatial allocation of information and security features in the card network with originally separated layers requires a sophisticated lamination technique with fitting devices such as dowel pins and fitting holes in the individual layers and thus represents a further safeguard against counterfeiting. The spatial allocation of two guilloche figures can also be done by double-sided , accurate print on the intermediate layer 7.

Fig. 4 zeigt einen Querschnitt durch die Identifikationskarte 10' nach Fig. 3, in dem die mattierten Schichten 3 und 4 schraffiert und die transparente Zwischenschicht 7 ohne Schraffur dargestellt ist.FIG. 4 shows a cross section through the identification card 10 'according to FIG. 3, in which the matted layers 3 and 4 are hatched and the transparent intermediate layer 7 is shown without hatching.

Die Abdeckschichten 1,2 können zusätzlich mit Sicherungsmerkmalen versehen sein, von denen in Fig. 4 das rechte Sicherheitsmerkmal 11 durch eine punktierte Linie, die durch Abstände unterbrochen ist, angedeutet ist. Das entsprechende linke Sicherheitsmerkmal ist wegen der besseren Übersichtlichkeit weggelassen worden. Die Sicherheitsmerkmale 11 zwischen dem Kartenkern und den Abdeckschichten 1 und 2 stehen zueinander gleichfalls in einer vorgegebenen räumlichen Anordnung und ergeben dadurch eine erhöhte Sicherheit gegenüber Fälschungen.The cover layers 1, 2 can additionally be provided with security features, of which the right security feature 11 is indicated in FIG. 4 by a dotted line which is interrupted by distances. The corresponding left security feature has been omitted for clarity. The security features 11 between the card core and the cover layers 1 and 2 are also mutually in a predetermined spatial arrangement and thereby result in increased security against counterfeiting.
