Description

Die Erfindung betrifft ein Identifikationsdokument mit einer personalisierten ersten visuellen Kennzeichnung, welche in einem ersten Bereich des Identifikationsdokuments angeordnet ist, wobei der erste Bereich derart konfiguriert ist, dass bei Laserbestrahlung desselben aus Materialumwandlungen resultierende lokalen Verdunklungen des optischen Eindrucks des Identifikationsdokuments erzeugt werden. Weiterhin betrifft die Erfindung ein Herstellungsverfahren für ein Identifikationsdokument.The invention relates to an identification document with a personalized first visual identification, which is arranged in a first region of the identification document, wherein the first region is configured in such a way that upon laser irradiation of the same from local material transformations resulting local obscurations of the visual impression of the identification document are generated. Furthermore, the invention relates to a production method for an identification document.

Identifikationsdokumente, wie beispielsweise Ausweiskarten, Kreditkarten, Bankkarten, Versicherungskarten, Mitgliedschaftskarten, Zugangskarten, elektronische Geldbörsen und dergleichen, werden in steigendem Maße in verschiedenen Dienstleistungssektoren, aber auch im innerbetrieblichen Bereich eingesetzt. Sie müssen dabei in der Regel zwei gegenläufige Bedingungen erfüllen. So stellen sie wegen ihrer großen Verbreitung zum einen ein Massenprodukt dar, das einfach und kostengünstig herzustellen sein soll. Zum anderen sollen sie aufgrund ihrer Legitimationsfunktion größtmögliche Sicherheit gegen Fälschung oder Verfälschung bieten. Die Vielzahl der erhältlichen Arten von Ausweiskarten ist Zeugnis für die zahlreichen Bemühungen und die verschiedenartigen Vorschläge, wie diese gegenläufigen Anforderungen in geeigneter Weise miteinander verbunden werden können.Identification documents such as identity cards, credit cards, bank cards, insurance cards, membership cards, access cards, electronic wallets and the like are increasingly used in various service sectors, but also in the in-house area. They usually have to meet two opposing conditions. Because of their widespread use, they are a mass-produced product that should be simple and inexpensive to produce. On the other hand, they should offer the greatest possible security against counterfeiting or falsification due to their legitimacy function. The variety of types of ID cards available is testimony to the numerous efforts and various suggestions as to how these conflicting requirements can be properly linked.

Beispielsweise ist aus der deutschen Patentschrift DE 31 51 407 C1 eine mehrschichtige Ausweiskarte bekannt, die mit einer Plastikfolie als Aufzeichnungsmedium ausgestattet ist. Die Plastikfolie erscheint im sichtbaren Wellenlängenbereich völlig intransparent, absorbiert jedoch bei der Wellenlänge eines zum Einschreiben von Informationen benutzten Infrarotlasers so stark, dass sich durch die Einwirkung der Laserstrahlung eine lokale Schwärzung der Folie ergibt. Damit können Bilder und/ oder Daten mit einer guten Auflösung in die Plastikfolie eingeschrieben werden.For example, from the German patent specification DE 31 51 407 C1 a multi-layered ID card is known, which is equipped with a plastic sheet as a recording medium. The plastic film appears completely intransparent in the visible wavelength range, but absorbs so strongly at the wavelength of an infrared laser used for writing information that localized blackening of the film results from the action of the laser radiation. This allows images and / or data to be written in the plastic film with a good resolution.

Jedoch sind derartige lasergravierte Bilder nicht vor nachträglicher Hinzufügung zusätzlicher Informationen sicher. So ist es z.B. möglich, mittels eines Laserstrahls nachträglich Bereiche des Bildes zu schwärzen. Ein Portraitfoto kann so wesentlich verändert werden, z.B. durch Hinzufügen von zusätzlichen Haaren, eines Bartes oder einer Brille. Um derartige Fälschungen bei Identifikationsdokumenten zu verhindern, werden unterschiedliche Sicherungsmaßnahmen ergriffen. Beispiele umfassen das Hinzufügen von Hologrammen oder in Bildern oder Text versteckten Mikro-Buchstaben.However, such laser engraved images are not safe from the subsequent addition of additional information. So it is e.g. possible to subsequently blacken areas of the image by means of a laser beam. A portrait photo can be so significantly changed, e.g. by adding extra hair, a beard or a pair of glasses. To prevent such counterfeits in identification documents, different security measures are taken. Examples include adding holograms or micro-letters hidden in images or text.

Diese Maßnahmen sind jedoch verhältnismäßig aufwändig und können oft nur mit technischen Geräten zuverlässig identifiziert werden.However, these measures are relatively complex and can often be reliably identified only with technical equipment.

Dokument EP-A-1 935 664 offenbart ein Identifikationsdokument nach dem Oberbegriff des Anspruchs 1.document EP-A-1 935 664 discloses an identification document according to the preamble of claim 1.

Ausgehend davon liegt der Erfindung die Aufgabe zugrunde, ein Identifikationsdokument bereitzustellen, das schwer zu fälschen ist und dessen Echtheit insbesondere ohne großen Aufwand überprüfbar ist, sowie ein Verfahren zur Herstellung eines derartigen Identifikationsdokuments bereitzustellen.Proceeding from this, the object of the invention is to provide an identification document which is difficult to falsify and whose authenticity can be checked in particular without great effort, and to provide a method for producing such an identification document.

Diese Aufgabe wird durch das Identifikationsdokument und das Herstellungsverfahren mit den Merkmalen der unabhängigen Ansprüche gelöst. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the identification document and the manufacturing method having the features of the independent claims. Further developments of the invention are the subject of the dependent claims.

Gemäß der Erfindung weist ein gattungsgemäßes Identifikationsdokument eine zweite visuelle Kennzeichnung auf, welche den optischen Eindruck einer Kopie der ersten visuellen Kennzeichnung erzeugt. Die zweite visuelle Kennzeichnung ist in einem zweiten Bereich des Identifikationsdokuments angeordnet. Der zweite Bereich ist derart konfiguriert, dass bei Laserbestrahlung desselben aus Materialumwandlungen resultierende lokale Aufhellungen des optischen Eindrucks des Identifikationsdokuments erzeugt werden.According to the invention, a generic identification document has a second visual identification which produces the visual impression of a copy of the first visual identification. The second visual identification is arranged in a second area of the identification document. The second region is configured in such a way that, upon laser irradiation of the same, resulting from material conversions, local brightenings of the visual impression of the identification document are produced.

Mit anderen Worten umfasst das Identifikationsdokument zwei Bereiche, wobei durch Laserbestrahlung im einen Bereich lokale Verdunklungen und im anderen Bereich lokale Aufhellungen des optischen Eindrucks erzeugt werden können. Beide Bereiche weisen visuelle Kennzeichnungen, wie z.B. ein Portraitfoto des Inhabers des Identifikationsdokuments auf, wobei die visuelle Kennzeichnung im zweiten Bereich den optischen Eindruck einer Kopie der visuellen Kennzeichnung im ersten Bereich erzeugt. Darunter ist zu verstehen, dass die zweite visuelle Kennzeichnung den Eindruck eines Positiv-Bildes der ersten visuellen Kennzeichnung erzeugt, d.h. dunkle Bereiche in der ersten visuellen Kennzeichnung entsprechen dunklen Bereichen in der zweiten visuellen Kennzeichnung und helle Bereiche entsprechen hellen Bereichen. Der Farbeindruck und die Größe der zweiten visuellen Kennzeichnung können, müssen jedoch nicht vollständig mit dem Farbeindruck und der Größe der ersten visuellen Kennzeichnung übereinstimmen. Vielmehr kann die zweite visuelle Kennzeichnung gegenüber der ersten visuellen Kennzeichnung im Maßstab verkleinert oder auch vergrößert sein. Auch der Farbeindruck der zweiten Kennzeichnung kann von dem Farbeindruck der ersten Kennzeichnung abweichen und beispielsweise statt von Weiß (hell) nach Schwarz (dunkel) von Silber (hell) zu Blau (dunkel) reichen.In other words, the identification document comprises two areas, whereby local darkening can be generated by laser irradiation in one area and local brightening of the visual impression in the other area. Both areas have visual markings, e.g. a portrait photo of the owner of the identification document, wherein the visual identification in the second area creates the visual impression of a copy of the visual identification in the first area. By this is meant that the second visual identification produces the impression of a positive image of the first visual identification, i. Dark areas in the first visual tag correspond to dark areas in the second visual tag and bright areas correspond to bright areas. The color impression and the size of the second visual marking may or may not be completely consistent with the color impression and size of the first visual mark. Rather, the second visual identification can be reduced in size or enlarged compared to the first visual identification. Also, the color impression of the second marking may differ from the color impression of the first marking and, for example, instead of white (light) to black (dark) ranging from silver (light) to blue (dark).

Weiter können die erste und/ oder insbesondere die zweite visuelle Kennzeichnung durch eine optisch variable Farbe gebildet sein, deren Farbeindruck für den Betrachter sich mit dem Betrachtungswinkel ändert (Farbkippeffekt). In diesem Fall ist der Farbkippeffekt einem helleren oder dunkleren Farbeindruck der Teilbereiche der visuellen Kennzeichnung überlagert.Furthermore, the first and / or in particular the second visual identification can be formed by an optically variable color whose color impression for the viewer changes with the viewing angle (color-shift effect). In this case, the color shift effect is superimposed on a lighter or darker color impression of the subregions of the visual identification.

Dadurch, dass die jeweiligen, die beiden visuellen Kennzeichnungen enthaltenden Bereiche jedoch, wie vorstehend beschrieben, entgegengesetzt auf Laserstrahlung reagieren, nämlich einmal durch einen dunkler werdenden und einmal durch einen heller werdenden optischen Eindruck, ist es für einen potentiellen Fälscher schwer bzw. fast unmöglich, die beiden visuellen Kennzeichnungen so zu manipulieren, dass der überstimmende optische Eindruck erhalten bleibt. Wird etwa in der ersten visuellen Kennzeichnung mittels eines Laserstrahls eine zusätzliche Linie erzeugt, so erscheint diese dunkel. Bei entsprechender Bearbeitung der zweiten visuellen Kennzeichnung mittels eines Laserstrahls lässt sich jedoch lediglich eine Aufhellung in einem bereits dunklen Hintergrund erzeugen. Eine zur Manipulation der ersten visuellen Kennzeichnung analoge Erzeugung einer dunklen Linie ist hingegen nicht möglich.However, as a result of the fact that the respective regions containing the two visual markings react in opposite directions, as described above, to laser radiation, namely once through one darkening and sometimes brightening visual impression, it is difficult or almost impossible for a potential forger to manipulate the two visual markings so that the harmonized visual impression is maintained. If, for example, an additional line is generated in the first visual marking by means of a laser beam, it appears dark. With appropriate processing of the second visual marking by means of a laser beam, however, only a brightening in an already dark background can be produced. A generation of a dark line analogous to the manipulation of the first visual identification, however, is not possible.

Da die zweite visuelle Kennzeichnung den optischen Eindruck einer Kopie der ersten visuellen Kennzeichnung erzeugt, kann eine Überprüfung der Echtheit des Identifikationsdokuments durch einfachen Vergleich der beiden Kennzeichnungen mit bloßem Auge erfolgen. Abweichungen zwischen den Kennzeichnungen sind für den Betrachter leicht erkennbar. Auf diese Weise kann eine eventuelle Manipulation des Identifikationsdokuments durch einen Vergleich der beiden visuellen Kennzeichnungen ohne Verwendung von Hilfsmitteln auch von einem Laien leicht erkannt werden. Besondere technische Geräte sind für die Echtheitsprüfung nicht notwendig. Insbesondere ist die erste visuelle Kennzeichnung ein Portraitfoto des Inhabers des Identifikationsdokuments. Alternativ oder zusätzlich kann die visuelle Kennzeichnung auch personenbezogene Daten des Inhabers in Form von Buchstaben und/oder Zahlen aufweisen.Since the second visual identification produces the visual impression of a copy of the first visual identification, verification of the authenticity of the identification document can be carried out by simply comparing the two identifications with the naked eye. Deviations between the markings are easily recognizable to the viewer. In this way, a possible manipulation of the identification document by comparing the two visual identifiers without the use of tools also be easily recognized by a layman. Special technical devices are not necessary for the authenticity check. In particular, the first visual identification is a portrait photo of the owner of the identification document. Alternatively or additionally, the visual identification may also include personal data of the owner in the form of letters and / or numbers.

Der zweite Bereich ist derart konfiguriert, dass die bei Laserbestrahlung erzeugten Aufhellungen im zweiten Bereich aufgrund von lokalen Farbumwandlungen des Identifikationsdokuments von einer dunklen Farbe zu einer hellen Farbe bewirkt werden. Dies kann beispielsweise eine Farbumwandlung von Blau zu Silber sein. Dazu weist der zweite Bereich vorteilhafterweise eine optisch variable Tinte, d.h. eine Tinte mit speziellen Pigmenten, auf, deren Farbe sich bei Laserstrahlungseinwirkung verändert. Die optisch variable Tinte liegt vorzugsweise auf einer inneren Schicht des Identifikationsdokuments im zweiten Bereich. Es können neben optisch variablen Tinten auch andere Farben oder Tinten verwendet werden, bei denen eine Laserbestrahlung zu einer Farbumwandlung führt.The second region is configured such that the lightening in the second region produced upon laser irradiation is caused from a dark color to a light color due to local color transformations of the identification document. This can be, for example, a color conversion from blue to silver. For this purpose, the second region advantageously comprises an optically variable ink, i. an ink with special pigments, whose color changes when exposed to laser radiation. The optically variable ink is preferably located on an inner layer of the identification document in the second area. In addition to optically variable inks, it is also possible to use other colors or inks in which a laser irradiation leads to a color conversion.

Es ist vorteilhalf, wenn der erste Bereich ein Material aufweist, bei dem Laserstrahlungseinwirkung eine Schwärzung hervorruft. Dies kann ein Kunststoffmaterial sein, wie beispielsweise Polycarbonat oder Polyvinylchlorid, in dem Absorberpartikel enthalten sind, welche bei Laserbestrahlung reagieren und damit eine Schwärzung verursachen, wie aus der Lasergravur bekannt.It is advantageous if the first region comprises a material which causes blackening of the laser radiation. This may be a plastic material, such as polycarbonate or polyvinylchloride, which contains absorber particles which react upon laser irradiation to cause blackening, as known from laser engraving.

Weiterhin ist es vorteilhaft, wenn das Identifikationsdokument ein auf einem Trägerelement des Identifikationsdokuments aufgebrachtes selbsttragendes Transferelement, wie etwa ein Patch oder ein Etikett, umfasst und das Transferelement die zweite visuelle Kennzeichnung enthält. Vorteilhaft ist es, die zweite visuelle Kennzeichnung im Inneren des Patches vorzusehen, so daß sie vor äußeren Einflüssen geschützt wird. Ein derartiges Transferelement wird typischerweise erst nach seiner Herstellung auf dem Identifikationsdokument aufgebracht.Furthermore, it is advantageous if the identification document comprises a self-supporting transfer element applied to a carrier element of the identification document, such as a patch or a label, and the transfer element contains the second visual identification. It is advantageous to provide the second visual identification inside the patch, so that it is protected from external influences. Such a transfer element is typically applied to the identification document only after its manufacture.

Es ist auch möglich, den Patch in das Identifikationsdokument einzulaminieren. Hierzu wird das Identifikationsdokument im Rohzustand mit dem Patch versehen und anschließend werden zum Schutz zusätzliche, ganz oder teilweise transparente Folien in einem Laminierungsprozeß mit dem Identifikationsdokument verbunden. Die zweite visuelle Kennzeichnung kann auf der Oberfläche des Patches oder auf einer inneren Schicht angeordnet sein.It is also possible to copy the patch into the identification document. For this purpose, the identification document is provided in the raw state with the patch and then additional, completely or partially transparent films are connected in a lamination process with the identification document for protection. The second visual tag may be disposed on the surface of the patch or on an inner layer.

Gemäß einer weiteren Ausgestaltung weist das Identifikationsdokument die Form einer Karte auf. Beispiele für derartige kartenförmige Identifikationsdokumente umfassen Ausweiskarten, Kreditkarten, Bankkarten, Versicherungskarten, Mitgliedschaftskarten, Zugangskarten und elektronische Geldbörsen. Alternativ kann das Identifikationsdokument jedoch auch nicht kartenförmig, z.B. als Datenseite eines Reisepasses, ausgebildet sein.According to a further embodiment, the identification document in the form of a map. Examples of such card-shaped identification documents include identity cards, credit cards, bank cards, insurance cards, membership cards, access cards and electronic purses. Alternatively, however, the identification document may not be card-shaped, e.g. be designed as a data page of a passport.

Gemäß einer Ausgestaltung der Erfindung wird das Identifikationsdokument aus mehreren Schichten aufgebaut. Das Verbinden der einzelnen Schichten erfolgt durch ein Laminierverfahren oder ein anderes geeignetes Verfahren.According to one embodiment of the invention, the identification document is composed of several layers. The bonding of the individual layers takes place by a lamination process or another suitable process.

Weiterhin wird erfindungsgemäß ein Verfahren zum Herstellen eines Identifikationsdokuments nach Anspruch 10 bereitgestellt. Mittels dieses Verfahrens lässt sich das vorstehend beschriebene, erfindungsgemäße Identifikationsdokument herstellen.Furthermore, a method for producing an identification document according to claim 10 is provided according to the invention. By means of this method, the above-described inventive identification document can be produced.

Der zweite Laserstrahl kann die gleichen Eigenschaften, insbesondere die gleiche Wellenlänge, wie der erste Laserstrahl aufweisen und damit der gleiche Laserstrahl sein. Alternativ kann sich der zweite Laserstrahl auch, insbesondere hinsichtlich seiner Wellenlänge, vom ersten Laserstrahl unterscheiden.The second laser beam may have the same properties, in particular the same wavelength, as the first laser beam and thus be the same laser beam. Alternatively, the second laser beam may also differ, in particular with regard to its wavelength, from the first laser beam.

Gemäß einer Ausgestaltung des erfindungsgemäßen Verfahrens wird bei der Bestrahlung des Identifikationselements mittels des ersten Laserstrahls kumulativ über die Bestrahlungsdauer oder die Bestrahlungsintensität in einem ersten Bereich des Identifikationselements ein erstes zweidimensionales Strahlungsmuster erzeugt und bei der Bestrahlung des Identifikationselements mittels des zweiten Laserstrahls in einem zweiten Bereich des Identifikationselements ebenfalls kumulativ über die Bestrahlungsdauer/Bestrahlungsintensität ein gegenüber dem ersten Strahlungsmuster invertiertes zweites zweidimensionales Strahlungsmuster erzeugt. Das heißt, Punkte bzw. Flächenabschnitte im zweiten Bereich, welche mit hoher Laserintensität bestrahlten Punkten bzw. Flächenabschnitten im ersten Bereich entsprechen, werden mit geringer Laserintensität oder gar nicht bestrahlt. Entsprechend werden Punkte bzw. Flächenabschnitte im zweiten Bereich, welche nicht oder lediglich mit geringer Laserintensität bestrahlten Punkte oder Flächenabschnitten im ersten Bereich entsprechen, mit hoher Laserintensität bestrahlt.According to one embodiment of the method according to the invention is in the irradiation of the identification element Cumulatively generated by the first laser beam over the irradiation time or the irradiation intensity in a first region of the identification element, a first two-dimensional radiation pattern and the irradiation of the identification element by the second laser beam in a second region of the identification element also cumulative over the irradiation time / irradiation intensity with respect to the first radiation pattern inverted second two-dimensional radiation pattern generated. That is to say, points or area sections in the second area which correspond to points or area sections irradiated with high laser intensity in the first area are irradiated with low laser intensity or not at all. Correspondingly, points or area sections in the second area which correspond to points or area sections in the first area that are not or only irradiated with low laser intensity are irradiated with high laser intensity.

Das zweite Strahlungsmuster kann gegenüber dem ersten Strahlungsmuster verkleinert oder vergrößert sein. Die sich durch die Bestrahlung ergebenden visuellen Kennzeichnungen sind entsprechend zueinander vergrößert bzw. verkleinert.The second radiation pattern may be reduced or enlarged relative to the first radiation pattern. The visual identifications resulting from the irradiation are enlarged or reduced corresponding to one another.

Gemäß einer Ausführungsform werden bei der Bestrahlung des Identifikationsdokuments mittels des ersten Laserstrahls lokale Schwärzungen in einem ersten Bereich des Identifikationsdokuments bewirkt. Vorteilhafterweise werden bei der Bestrahlung des Identifikationsdokuments mittels des zweiten Laserstrahls lokale Farbumwandlungen in einem zweiten Bereich des Identifikationsdokuments von einer dunklen Farbe zu einer hellen Farbe, insbesondere von Blau zu Silber, bewirkt.According to one embodiment, upon irradiation of the identification document by means of the first laser beam, local blackening is effected in a first region of the identification document. When the identification document is irradiated by means of the second laser beam, local color conversions in a second region of the identification document from a dark color to a light color, in particular from blue to silver, are advantageously effected.

Weiterhin ist es vorteilhaft, wenn bei der Bestrahlung des Identifikationsdokuments mittels des zweiten Laserstrahls ein Transferelement, wie etwa ein Patch oder ein Etikett, zur Bewirkung der die zweite visuelle Kennzeichnung sichtbar machenden Materialumwandlungen bestrahlt wird und das Transferelement nach der Bestrahlung auf einem Trägerelement des Identifikationsdokuments aufgebracht wird.Furthermore, it is advantageous if, during the irradiation of the identification document by means of the second laser beam, a transfer element, such as a patch or a label, is irradiated for effecting the material transformations visualizing the second visual marking and the transfer element is applied after irradiation to a carrier element of the identification document becomes.

Weitere Ausführungsbeispiele sowie Vorteile der Erfindung werden nachfolgend anhand der beigefügten schematischen Zeichnungen erläutert, bei deren Darstellung auf eine maßstabs- und proportionsgetreue Wiedergabe verzichtet wurde, um die Anschaulichkeit zu erhöhen.Further embodiments and advantages of the invention will be explained below with reference to the accompanying diagrammatic drawings, in the representation of which a representation true to scale and proportion has been omitted in order to increase the clarity.

Die Erfindung wird nun am Beispiel eines in den Figuren 1 und 2 schematisch dargestellten Identifikationsdokumentes beschrieben. Fig.1 zeigt das Identifikationsdokument in Gestalt einer Ausweiskarte 10, z.B. in Gestalt einer Personalausweiskarte oder einer Führerscheinkarte in Aufsicht. Die Erfindung ist jedoch nicht auf derartige Ausweiskarten beschränkt, vielmehr kann das Identifikationsdokument auch in beliebigen Formaten, wie etwa als personalisierte Datenseite eines Reisepasses, ausgebildet sein.The invention will now be described by way of example in the Figures 1 and 2 Described schematically illustrated identification document. Fig.1 shows the identification document in the form of an identity card 10, for example in the form of an identity card or driver's license card in supervision. However, the invention is not limited to such identification cards, but rather the identification document can also be embodied in any formats, such as a personalized data page of a passport.

Die Ausweiskarte 10 enthält in einem ersten Bereich 12 eine personalisierte erste visuelle Kennzeichnung 14 in Gestalt eines Portraitfotos des Karteninhabers. Neben dem Portraitfoto sind weitere personenbezogene Daten 20, im Ausführungsbeispiel Vorname, Nachname sowie Geburtsdatum des Inhabers angeordnet. Darüber hinaus kann die Ausweiskarte weitere Daten, wie etwa Nationalität, Ausstellungsbehörde, Ausstellungsdatum und dergleichen, enthalten.The ID card 10 contains in a first area 12 a personalized first visual identification 14 in the form of a portrait photo of the cardholder. In addition to the portrait photo, further personal data 20, in the exemplary embodiment first name, last name and date of birth of the owner are arranged. In addition, the ID card may include other data such as nationality, issuing authority, issue date, and the like.

Die Ausweiskarte 10 umfasst darüber hinaus einen zweiten Bereich 22 mit einer zweiten visuellen Kennzeichnung 26. Der zweite Bereich 22 wird von einem Transferelement 24 in Gestalt eines Patches oder Etiketts, insbesondere in Gestalt eines sogenannten "STEP® Sign-Druckes" gebildet, das ein Patch darstellt, das mit einer besonderen optisch variable Tinte (auch OVI® für Optically Variable Ink) bedruckt ist, wie weiter unten beschrieben. Das Transferelement 24 ist, wie aus der Querschnittsdarstellung in Fig. 2 ersichtlich, auf einer inneren Schicht eines Hauptkörpers 18 der Ausweiskarte 10 aufgebracht. Die zweite visuelle Kennzeichnung 26 zeigt das Portraitfoto des Karteninhabers aus dem ersten Bereich 12 in verkleinerter Darstellung. Genauer gesagt, erzeugt die zweite visuelle Kennzeichnung 26 den optischen Eindruck einer verkleinerten Kopie des die erste visuelle Kennzeichnung 14 bildenden Portraitfotos. Alternativ kann die zweite visuelle Kennzeichnung 26 auch das Portraitfoto im gleichen Maßstab wie die erste visuelle Kennzeichnung 14 oder auch in vergrößertem Maßstab wiedergeben.The badge 10 further comprises a second area 22 with a second visual marking 26. The second area 22 is formed by a transfer element 24 in the form of a patch or label, in particular in the form of a so-called "STEP® sign print", which is a patch which is printed with a special optically variable ink (also OVI® for Optically Variable Ink), as described below. The transfer element 24 is, as shown in the cross-sectional view in FIG Fig. 2 can be seen on an inner layer of a main body 18 of the badge 10 applied. The second visual identification 26 shows the portrait photo of the cardholder from the first area 12 in a reduced representation. More specifically, the second visual mark 26 produces the visual impression of a downsized copy of the portrait photograph forming the first visual mark 14. Alternatively, the second visual mark 26 can also reproduce the portrait photo on the same scale as the first visual mark 14 or on an enlarged scale.

Im ersten Bereich 12 enthält die Ausweiskarte 10 im Bereich der Oberfläche des Hauptkörpers 18 eine lasersensitive Aufzeichnungsschicht 16. Bei der Aufzeichnungsschicht 16 kann es sich um einen Teilbereich des Hauptkörpers 18, und insbesondere wie in Fig. 2 beispielhaft dargestellt, um einen sich lediglich im ersten Bereich 12 erstreckenden oberflächennahen Teilbereich handeln. Es kann sich bei der Aufzeichnungsschicht 16 aber auch um eine separate Schicht des Hauptkörpers 18 handeln. Weiterhin kann auch der gesamte Hauptkörper 18 die lasersensitive Auszeichnungsschicht 16 bilden. Der Hauptkörper 16 der Ausweiskarte 10 kann aus einem Kunststoffmaterial, wie beispielsweise Polycarbonat (PC) oder Polyvinylchlorid (PVC), gefertigt sein. Der Hauptkörper kann ferner einen Schichtaufbau aufweisen. In der lasersensitiven Aufzeichnungsschicht 16 sind typischerweise Absorberpartikel in dem Kunststoffmaterial enthalten. Die Absorberpartikel werden bei Bestrahlung mit einem Laserstrahl geschwärzt.In the first area 12, the ID card 10 contains a laser-sensitive recording layer 16 in the region of the surface of the main body 18. The recording layer 16 may be a portion of the main body 18, and in particular as in FIG Fig. 2 exemplified, to act only in the first region 12 extending near-surface portion. However, the recording layer 16 may also be a separate layer of the main body 18. Furthermore, the entire main body 18 may also form the laser-sensitive mark layer 16. The main body 16 of the badge 10 may be made of a plastic material such as polycarbonate (PC) or polyvinyl chloride (PVC). The main body may further have a layer structure. In the laser-sensitive recording layer 16, absorber particles are typically contained in the plastic material. The absorber particles are blackened when irradiated with a laser beam.

Damit ist es möglich, durch geeignete Laserbestrahlung in der Aufzeichnungsschicht 16 das Portraitfoto des Karteninhabers als Schwarzweißbild zu erzeugen. Dazu eignet sich insbesondere ein gepulster Infrarotlaser. Das Verfahren zur Erzeugung des Portraitfotos ist auch als Lasergravur bekannt. Allgemein ausgedrückt, wird das Portraitfoto im ersten Bereich 12 durch derartige Bestrahlung der Aufzeichnungsschicht 16 erzeugt, dass lokale Verdunklungen des optischen Eindrucks der Aufzeichnungsschicht 16 hervorrufende Materialumwandlungen bewirkt werden.This makes it possible, by suitable laser irradiation in the recording layer 16, to produce the portrait photo of the cardholder as a black-and-white image. In particular, a pulsed infrared laser is suitable for this purpose. The method for producing the portrait photo is also known as laser engraving. Generally speaking, the portrait photograph is formed in the first area 12 by irradiating the recording layer 16 so as to cause local darkening of the optical impression of the recording layer 16 causing material conversions.

Das Transferelement 24 enthält eine optisch variable Tinte, die nicht nur einen üblichen Farbkippeffekt zeigt, sondern die auch lasergravierbar ist, wobei sich die anfängliche blaue Eigenfarbe bei Einwirkung von Laserstrahlung zu einem mehr oder weniger silbernen Farbeindruck verändert. Mit steigender Intensität der Laserstrahlung verschwindet ein zunehmender Anteil der ursprünglichen blauen (dunkleren) Farbe und der Anteil der silbernen (helleren) Farbe nimmt zu.The transfer element 24 contains an optically variable ink which not only exhibits a customary color-shift effect but which is also laser-engravable, the initial blue intrinsic color changing to a more or less silver color impression upon exposure to laser radiation. As the intensity of the laser radiation increases, an increasing proportion of the original blue (darker) color disappears and the proportion of the silver (lighter) color increases.

Die Erfindung ist selbstverständlich nicht auf Tinten mit einem Übergang von Blau zu Silber beschränkt. Im allgemeinen Fall wandelt sich eine mit geeigneten Pigmenten versehene Tinte bei Laserbestrahlung von einer dunklen Farbe zu einer hellen Farbe um. Damit lassen sich durch Laserbestrahlung des Transferelements 24 aus Materialumwandlungen resultierende lokale Aufhellungen des optischen Eindrucks erzeugen. Das die zweite visuelle Kennzeichnung 26 bildende Portraitfoto wird durch entsprechende Laserbestrahlung erzeugt. Die Wellenlänge des dafür versendeten Laserlichts kann identisch mit der zur Erzeugung der ersten visuellen Kennzeichnung 14 verwendeten Laserwellenlänge sein, und z.B. im Infrarotbereich liegen. Andere Wellenlängen können allerdings auch verwendet werden.Of course, the invention is not limited to inks having a blue to silver transition. In the general case, an ink provided with suitable pigments will change from a dark color to a light color upon laser irradiation. This can be generated by laser irradiation of the transfer element 24 from material conversions resulting local brightening of the visual impression. The portrait photo forming the second visual identification 26 is generated by appropriate laser irradiation. The wavelength of the laser light sent therefor may be identical to the laser wavelength used to produce the first visual tag 14, and e.g. lie in the infrared range. Other wavelengths, however, can also be used.

Wie bereits vorstehend erwähnt, soll die zweite visuelle Kennzeichnung 26 den optischen Eindruck einer Kopie der ersten visuellen Kennzeichnung 14 aufweisen. Aufgrund der inversen Reaktion der optisch variablen Tinte im durch das Transferelement 24 gebildeten zweiten Bereich 22 auf Laserstrahlung im Vergleich zu der Reaktion der Aufzeichnungsschicht 16 im ersten Bereich 12 ist die Strahlungsverteilung der Laserstrahlung beim Beschreiben des zweiten Bereichs 22 invers zur Strahlungsverteilung beim Beschreiben des ersten Bereichs 12 konfiguriert. Während bei der ersten visuellen Kennzeichnung 14 dunkle Bildstellen mit hoher Laserenergie und helle Bildstellen mit niedriger Laserenergie erzeugt werden, werden bei der zweiten visuellen Kennzeichnung 26 helle, im Ausführungsbeispiel silberne, Bildstellen mit hoher Laserenergie und dunkle, im Ausführungsbeispiel blaue, Bildstellen mit niedriger Laserenergie erzeugt.As already mentioned above, the second visual identification 26 should have the visual impression of a copy of the first visual identification 14. Due to the inverse response of the optically variable ink in the second region 22 formed by the transfer element 24 to laser radiation compared to the response of the recording layer 16 in the first region 12, the radiation distribution of the laser radiation in describing the second region 22 is inverse to the radiation distribution in describing the first region 12 configured. Whereas in the first visual identification 14 dark image areas with high laser energy and bright image areas with low laser energy are generated, in the second visual identification 26 bright, in the exemplary embodiment silver, image areas with high laser energy and dark, in the exemplary embodiment blue, image locations with low laser energy are generated ,

Mit anderen Worten wird in den zweiten Bereich 22 ein Negativ-Bild mit Positiv-Eindruck geschrieben. Die Portraitfotos in den beiden Bereichen 12 und 22 sind daher vom Eindruck her jeweils Positiv-Bilder und daher zur Verifizierung der Echtheit der Ausweiskarte 10 leicht vergleichbar. Versucht ein Fälscher nachträglich die Portraitfotos durch Laserbestrahlung zu manipulieren, so macht er die Erfahrung, dass der Laserstrahl im Portraitfoto des ersten Bereichs 12 dunkle Linien erzeugt, im Portraitfoto des zweiten Bereichs 22 hingegen helle Linien.In other words, a positive impression negative image is written in the second region 22. The portrait photos in the two areas 12 and 22 are therefore from the impression of each positive images and therefore easily to verify the authenticity of the ID card 10 comparable. If a counterfeiter attempts to manipulate the portrait photos by laser irradiation, he experiences that the laser beam creates 12 dark lines in the portrait photo of the first area, while in the portrait photo of the second area 22, on the other hand, there are light lines.

Eine konsistente nachträgliche Manipulation beider Portraitfotos, beispielsweise die Hinzufügung eines Bartes oder die Veränderung der Haarfarbe, wird damit außerordentlich erschwert bzw. sogar unmöglich gemacht. Eine derartige nachträgliche Manipulation ist in jedem Fall leicht ohne Verwendung optischer Hilfsmittel erkennbar.A consistent subsequent manipulation of both portrait photos, for example the addition of a beard or the change of the hair color, is made extremely difficult or even impossible. Such subsequent manipulation is easily recognizable in any case without the use of optical aids.

Weiterhin ist es denkbar, auch die personenbezogenen Daten 20 jeweils in die beiden Bereiche 12 und 22 aufzunehmen. Dies erschwert auch eine Manipulation dieser Daten, da hinzugefügte Schwärzungen im ersten Bereich 12 etwa in Form eines Linienelements zur Verwandlung der Zahl "3" in die Zahl "8" im zweiten Bereich 22 nicht oder nur schwer reproduzierbar wären.Furthermore, it is conceivable to also include the personal data 20 in each of the two areas 12 and 22. This also makes it difficult to manipulate this data, since added blackening in the first region 12, for example in the form of a line element for converting the number "3" into the number "8" in the second region 22, would not be reproducible or would be difficult to reproduce.

Es versteht sich, dass die Ausweiskarte 10 zusätzliche Schichten, beispielsweise eine oder mehrere Schutzschichten oder mit anderen Sicherheitselementen versehene Funktionsschichten, aufweisen kann. Diese weiteren Schichten sind weder in den Figuren gezeigt noch näher beschrieben. It is understood that the badge 10 may have additional layers, for example one or more protective layers or functional layers provided with other security elements. These further layers are neither shown nor described in detail in the figures.
