The carrier layer is arranged so as to face away from the thermo-functinal layers, where the color pigment is arranged in the upper thermo-functional layer or arranged in the lower thermo-functional layer such that the thermo-functional layers are arranged one above the other. An independent claim is also included for a method for manufacturing a document.

Description

Die Erfindung betrifft ein Dokument mit einer Trägerschicht und mindestens einer Funktionsschicht.The invention relates to a document with a carrier layer and at least one functional layer.

Die Erfindung betrifft darüber hinaus ein Verfahren zur Herstellung eines Dokumentes, bei dem auf einer Trägerschicht mindestens eine Funktionsschicht fixiert wird.The invention further relates to a method for producing a document in which at least one functional layer is fixed on a carrier layer.

Derartige Dokumente könnten beispielsweise als Fahrkarten oder Eintrittskarten ausgebildet sein. Diese Dokumente sind häufig mit einer Thermofunktionsschicht versehen, die unter Verwendung eines Thermodruckers gekennzeichnet wird. Derartige Thermoschichten werden häufig ohne schützende Deckschicht eingesetzt, was dazu führt, daß die durch den Thermodrucker generierte Schwärzung unter Verwendung von Lösemitteln wieder entfernt werden kann. Beispielsweise sind in vielen Haarsprays entsprechende Lösungsmittel enthalten.Such documents could be formed for example as tickets or tickets. These documents are often provided with a thermal function layer that is characterized using a thermal printer. Such thermosheets are often used without a protective overcoat, resulting in that the blackening generated by the thermal printer can be removed again using solvents. For example, many hairsprays contain appropriate solvents.

Nach einer Entfernung der originären Bedruckung kann das Dokument von einem Fälscher mit einem neuen Aufdruck versehen werden. Derartige Fälschungen erfolgen umfangreich im Zusammenhang mit Fahrkarten oder Eintrittskarten.After removal of the original print, the document may be reprinted by a counterfeiter. Such counterfeits are extensively related to tickets or tickets.

Aufgabe der vorliegenden Erfindung ist es, ein Dokument der einleitend genannten Art mit einer erhöhten Fälschungssicherheit zu versehen.Object of the present invention is to provide a document of the aforementioned type with an increased security against counterfeiting.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der Funktionsschicht als Farbpigment Bakteriorhodopsin enthalten ist.This object is achieved in that contained in the functional layer as a color pigment bacteriorhodopsin.

Weitere Aufgabe der vorliegenden Erfindung ist es, ein Verfahren der einleitend genannten Art derart zu verbessern, daß das hergestellte Dokument eine erhöhte Fälschungssicherheit aufweist.Another object of the present invention is to improve a method of the aforementioned type such that the document produced has increased security against counterfeiting.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Funktionsschicht als Farbpigment mit einem Anteil von Bakteriorhodopsin versehen wird und daß bei einem Bedrucken des Dokumentes im Bereich des Bakteriorhodopsins durch eine Energiezuführung eine im wesentlichen irreversible Farbänderung generiert wird.This object is achieved in that the functional layer is provided as a color pigment with a proportion of bacteriorhodopsin and that when printed on the document in the field of bacteriorhodopsin by a power supply, a substantially irreversible color change is generated.

Bei Bakteriorhodopsin handelt es sich um ein biologisches Farbpigment. Es handelt sich hierbei insbesondere um ein photochromes Retinalprotein. Das Bakteriorhodopsin ist hinsichtlich der vorgesehenen Anwendung hoch optimiert und zeigt einen lichtinduzierten kontrastreichen und im Grundzustand reversiblen Farbwechsel zwischen violett und gelb bzw. anderen Farbkombinationen. Dieser Farbwechsel ist visuell durch einen Betrachter leicht erkennbar.Bacteriorhodopsin is a biological color pigment. This is in particular a photochromic retinal protein. The bacteriorhodopsin is highly optimized with regard to the intended application and shows a light-induced high-contrast and in the ground state reversible color change between violet and yellow or other color combinations. This color change is easily recognizable visually by a viewer.

Ein anderes optisches Verhalten des Bakteriorhodopsins ergibt sich, wenn dieses Farbpigment nicht mit normalem Umgebungslicht, sondern mit kohärentem Licht, insbesondere mit Laserlicht, bestrahlt wird. Eine derartige Bestrahlung führt zu einem irreversiblen Farbwechsel, der sich auch bei einer Beendigung der Beleuchtung bzw. der Bestrahlung sich nicht wieder verändert.Another optical behavior of the bacteriorhodopsin arises when this color pigment is not irradiated with normal ambient light, but with coherent light, in particular with laser light. Such irradiation leads to an irreversible color change, which does not change again even when the illumination or the irradiation is terminated.

Erfindungsgemäß wurde erkannt, daß dieser irreversible Farbwechsel ursächlich nicht durch die Art der Bestrahlung, sondern durch die vom kohärenten Licht generierte Energiezufuhr zu den Farbpigmenten hervorgerufen wird. Bei einem Bedrucken eines Thermopapiers oder einer anderen thermosensitiven Beschichtung wird ein Thermo-Druckkopf verwendet, der eine Oberflächentemperatur von etwa 180°C bis 200°C aufweist. Die entsprechende Wärmeenergie dringt in das zu bedruckende Material ein und generiert einen Temperaturgradienten mit in Richtung auf das Materialinnere abnehmender Temperatur. Das Bakteriorhodopsin zeigt seinen irreversiblen Farbumschlag bei einer Temperatureinwirkung im Bereich von etwa 140°C, so daß bei einer Anordnung der Farbpigmente mit einem ausreichend geringen Abstand zur vom Thermokopf beaufschlagten Oberfläche eine derartige Einwirkungstemperatur zu erreichen ist.According to the invention it has been recognized that this irreversible color change is caused causally not by the type of irradiation, but by the generated by the coherent light energy supply to the color pigments. When printing a thermal paper or other thermosensitive coating, a thermal printhead having a surface temperature of about 180 ° C to 200 ° C is used. The corresponding heat energy penetrates into the material to be printed and generates a temperature gradient with decreasing temperature in the direction of the interior of the material. The bacteriorhodopsin shows its irreversible color change at a temperature in the range of about 140 ° C, so that in an arrangement of the color pigments with a sufficiently small distance from the surface acted upon by the thermal head to reach such an exposure temperature.

Insbesondere ist es möglich, die Konzentration des Bakteriorhodopsins in der Funktionsschicht derart gering zu halten, daß die jeweilige Färbung visuell von einem Betrachter nicht wahrnehmbar ist, sondern nur durch eine entsprechende Meßtapparatur sichtbar gemacht werden kann. Hierdurch werden ungewollte Farbveränderungen des Dokumentes vermieden.In particular, it is possible to keep the concentration of the bacteriorhodopsin in the functional layer so small that the respective coloration is visually imperceptible to a viewer, but can only be visualized by a corresponding measuring apparatus. As a result, unwanted color changes of the document are avoided.

Ein einfaches Bedrucken des Dokumentes wird dadurch unterstützt, daß die Funktionsschicht als eine Thermofunktionsschicht ausgebildet ist.A simple printing of the document is supported by the fact that the functional layer is formed as a thermal functional layer.

Eine verbesserte Funktionalität wird dadurch bereitgestellt, daß mindestens zwei Funktionsschichten übereinander angeordnet sind.An improved functionality is provided by the fact that at least two functional layers are arranged one above the other.

Zu einer einfachen Handhabung trägt es bei, daß die der Trägerschicht abgewandt angeordnete Funktionsschicht als Thermofunktionsschicht ausgebildet ist.For ease of use, it helps that the carrier layer facing away from the functional layer is formed as a thermal function layer.

Eine geringe erforderliche Eindringtiefe der einwirkenden Energie wird dadurch unterstützt, daß das Farbpigment in der oberen Funktionsschicht angeordnet ist.A small required penetration depth of the applied energy is supported by the fact that the color pigment is arranged in the upper functional layer.

Eine gegenüber äußeren Einflüssen sowie einem unbefugten Ablesen geschützte Anordnung der Farbpigmente wird dadurch erreicht, daß das Farbpigment in der unteren Funktionsschicht angeordnet ist.A protected against external influences and unauthorized reading arrangement of the color pigments is achieved in that the color pigment is arranged in the lower functional layer.

In den Zeichnungen sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigen:

Einen schematischen Querschnitt durch ein Dokument mit einer Anordnung von Bakteriorhodopsin als Farbpigment in einer unteren Funktionsschicht und

In the drawings, embodiments of the invention are shown. Show it:
Fig. 1
A schematic cross section through a document with an arrangement of bacteriorhodopsin as a color pigment in a lower functional layer and
Fig. 2
one opposite Fig. 1 modified arrangement with a use of bacteriorhodopsin within an upper thermal layer.

Fig. 1 zeigt eine teilweise Darstellung eines Querschnittes durch ein Dokument (1), das eine Trägerschicht (2) aufweist. Auf der Trägerschicht sind eine untere Funktionsschicht (3) sowie eine obere Funktionsschicht (4) angeordnet. Die untere Funktionsschicht (3) befindet sich hierbei zwischen der oberen Funktionsschicht (4) und der Trägerschicht (2). Fig. 1 shows a partial representation of a cross section through a document (1) having a carrier layer (2). On the carrier layer, a lower functional layer (3) and an upper functional layer (4) are arranged. The lower functional layer (3) is in this case between the upper functional layer (4) and the carrier layer (2).

Insbesondere ist daran gedacht, die Trägerschicht (2) als Basispapier und die untere Funktionsschicht (3) als einen Vorstrich auszubilden, der die Haftung der oberen Funktionsschicht (4) auf der Trägerschicht (2) verbessert. Die obere Funktionsschicht (4) ist typischerweise als eine Thermoschicht realisiert.In particular, it is intended to form the carrier layer (2) as a base paper and the lower functional layer (3) as a precoat, which improves the adhesion of the upper functional layer (4) on the carrier layer (2). The upper functional layer (4) is typically realized as a thermo-layer.

Gemäß dem Ausführungsbeispiel in Fig. 1 ist im Bereich der unteren Funktionsschicht (3) ein Farbpigment (5) angeordnet, das als Bakteriorhodopsin ausgebildet ist.According to the embodiment in Fig. 1 is in the region of the lower functional layer (3) a color pigment (5) arranged, which is designed as a bacteriorhodopsin.

Gemäß dem Ausführungsbeispiel in Fig. 2 ist das Farbpigment (5) im Bereich der oberen Funktionsschicht (4) angeordnet. Auch hier ist das Farbpigment (5) als Bakteriorhodopsin ausgebildet.According to the embodiment in Fig. 2 the color pigment (5) is arranged in the region of the upper functional layer (4). Again, the color pigment (5) is designed as a bacteriorhodopsin.

Grundsätzlich ist es möglich, alternativ zum Bakteriorhodopsin auch andere Retinalproteine als biologische Farbpigmente einzusetzen.In principle, it is possible, as an alternative to bacteriorhodopsin, to use other retinal proteins as biological color pigments.

Fertigungstechnisch wird die Trägerschicht (2) über die gesamte Breite mit den Funktionsschichten (3, 4) versehen.Manufacturing technology, the carrier layer (2) over the entire width with the functional layers (3, 4) is provided.

Ein Bedrucken der oberen Funktionsschicht (4) erfolgt unter Verwendung eines üblichen Thermokopfes. Dieser erzeugt im Bereich der oberen Funktionsschicht (4) eine aus dem Stand der Technik bekannte Schwärzung. Zusätzlich wird das im Bereich der unteren Funktionsschicht (3) und/oder der oberen Funktionsschicht (4) angeordnete Farbpigment irreversibel umgefärbt. Auch bei einer nachträglichen Entfernung des Aufdruckes auf der Thermoschicht und bei einem Ersetzen dieses originären Aufdruckes durch einen gefälschten Aufdruck bleibt durch die irreversible Umfärbung des Farbpigmentes der originäre Aufdruck detektierbar. Unter Verwendung geeigneter Lesegeräte, die gegebenenfalls durch die Thermoschicht hindurch die Umfärbung des Farbpigmentes detektieren, können entsprechende Fälschungen erkannt und die gefälschten Dokumente (1) sichergestellt werden.A printing of the upper functional layer (4) is carried out using a conventional thermal head. This generates in the upper functional layer (4) one of the state known in the art blackening. In addition, the color pigment arranged in the region of the lower functional layer (3) and / or the upper functional layer (4) is irreversibly repolished. Even with a subsequent removal of the imprint on the thermal layer and a replacement of this original imprint by a counterfeit imprint remains due to the irreversible coloration of the color pigment of the original imprint detectable. By using suitable readers, which optionally detect the coloration of the color pigment through the thermal layer, corresponding counterfeits can be identified and the counterfeit documents (1) can be ensured.
