Description

Die Erfindung betrifft einen Aufzeichnungsträger mit farbigen Bildinformationen, insbesondere Ausweis- oder Wertkarte. Solche Aufzeichnungsträger sind insbesondere als staatliche Identitätskarten, Pässe, Fahrausweise, Bankkarten und Kreditkarten allgemein bekannt. Bei solchen Aufzeichnungsträgern werden bei der sogenannten Personalisierung dieser Träger die individuellen Daten aufgebracht, insbesondere auf den Inhaber bezogenen, persönlichen Daten. Ein wesentlicher Teil der Personalisierung ist die farbige Bildinformation in der Form einer Fotografie des Auszuweisenden.The invention relates to a recording medium with colored Image information, especially ID card or prepaid card. Such record carriers are in particular as state identity cards, passports, tickets, bank cards and credit cards generally known. With such record carriers in the so-called personalization this carrier applied the individual data, especially personal data related to the owner. An essential part of personalization is that colored image information in the form of a photograph of the To be shown.

Es gibt zahlreiche Möglichkeiten, Farbbilder auf Aufzeichnungsträger aufzubringen. Insbesondere bekannt sind sogenannte Transferverfahren, bei denen Farbstoffe von Farbträgern durch Thermosublimation oder Thermodiffusion auf den Träger übertragen werden. Bekannt ist auch das Aufbringen von farbigen Bildinformationen mittels Ink-Jet-Geräten, mittels Thermodruck oder mittels Farblaserdruck.There are numerous options for color images on record carriers applied. So-called are known in particular Transfer processes in which dyes from color carriers by thermal sublimation or thermal diffusion the carrier be transferred. The application is also known colored image information using ink-jet devices, using thermal printing or using color laser printing.

Damit solche farbige Bildinformatione nur sehr schwer zu fälschen sind, ist es bekannt, ein Farbbild auf den Träger so zu übertragen, dass die Farben in den Kunststoffträger hineinwandern und damit nicht ohne weiteres zu entfernen sind. Aus der DE 4134539 ist es ferner bekannt, die Bildinformation in mindestens zwei Informationsteile aufzuteilen. Der eine Anteil ist hier ein Farbanteil und der andere ein Schwarzweissanteil.This makes such colored image information very difficult to obtain are fake, it is known to put a color image on the carrier so that the colors transfer into the plastic carrier hike in and thus not easily removed are. From DE 4134539 it is also known the image information to be divided into at least two pieces of information. The one part here is a color part and the others a black and white portion.

Ausweiskarten mit einem farbigen Bildteil sind auch aus der DE 4134539 und der DE 4417343 bekannt geworden.ID cards with a colored image part are also made DE 4134539 and DE 4417343 have become known.

Bekannt ist auch das Aufbringen von Informationen mittels eines Laserschreibers. Hierzu wird auf die DE 3151407 verwiesen. Bisher wurden Farbfotos im Thermodruck oder Thermosublimationsverfahren auf Träger aus PVC oder PET oder Kombinationen von unterschiedlichen Kunststoffen übertragen. Solche Kunststoffe haben jedoch den Nachteil, dass sie vergleichsweise schnell altern und sich bereits bei Temperaturen über 80°C verbiegen. Geeigneter wäre als Träger ein Kunststoff aus Polycarbonat. Dieser Kunststoff ist wesentlich länger haltbar als PVC und ist auch wesentlich hitzebeständiger. Bisher konnte jedoch ein Träger aus Polycarbonat nicht durch Auftragen von farbigen Bildinformationen mittels eines Thermoverfahrens personalisiert werden.The application of information by means of is also known a laser recorder. For this, reference is made to DE 3151407. So far, color photos have been made using thermal printing or thermal sublimation processes on supports made of PVC or PET or Transfer combinations of different plastics. However, such plastics have the disadvantage that they age comparatively quickly and are already at Bend temperatures above 80 ° C. Would be more suitable as a carrier a plastic made of polycarbonate. This plastic is lasts much longer than PVC and is also essential heat-resistant. So far, however, a carrier made of polycarbonate not by applying colored image information be personalized using a thermal process.

Der Erfindung liegt die Aufgabe zugrunde, einen Aufzeichnungsträger der genannten Art zu schaffen, der eine wesentlich längere Haltbarkeit als PVC aufweist und der mit farbigen Bildinformationen insbesondere mittels Thermodruck oder Thermosublimation personalisierbar ist.The invention has for its object a record carrier of the type mentioned, the one essential has a longer shelf life than PVC and with colored image information, in particular by means of thermal printing or thermal sublimation can be personalized.

Die Aufgabe ist bei einem gattungsgemässen Aufzeichnungsträger dadurch gelöst, dass die farbigen Bildinformationen auf eine zur Haftverbesserung behandelt Oberfläche einer Schicht aus Polycarbonat aufgebracht ist.

Insbesondere hat es sich gezeigt, dass ein behandelter Träger mittels eines Thermoverfahrens bedruckbar ist.The task is with a generic record carrier solved that the colored image information on a surface treated to improve adhesion Layer of polycarbonate is applied. An essential one The idea of the invention is that it was recognized that that by treating the surface of a layer polycarbonate colored image information on this Layer can be applied. In particular it has It has been shown that a treated carrier by means of a Thermal process is printable.

Eine besonders geeignete Behandlung besteht nach einer Weiterbildung der Erfindung darin, dass auf die genannte Oberfläche ein Lack als Haftvermittler aufgetragen wird. Ein besonders geeigneter Lack ist hierbei ein Siebdrucklack, insbesondere ein lösungsmittelhaltiger Siebdrucklack. Ein solcher Lack dringt in den Kunststoff ein und verändert die Moleküle in oberflächennahen Bereichen derart, das im Thermoverfahren aufgebrachte Farbstoffe in das Polycarbonat eindringen und haften. Insbesondere lassen sich hierbei Thermodruckfolien verwenden. Verwendbar sind auch Thermodruckverfahren, bei denen die zum Drucken verwendete Nadel ähnlich wie bei PVC in den Kunststoff eindringt.A particularly suitable treatment is after Further development of the invention in that the said A varnish is applied to the surface as an adhesion promoter. A particularly suitable varnish is a screen printing varnish, especially a solvent-based screen printing varnish. Such paint penetrates the plastic and changes the molecules in areas near the surface in such a way the dyes applied in the thermal process in the Polycarbonate penetrate and adhere. In particular let use thermal printing foils. Are usable also thermal printing processes in which the one used for printing Similar to PVC, the needle penetrates the plastic.

Die Erfindung betrifft zudem ein Verfahren zum Herstellen eines Aufzeichnungsträgers mit farbigen Bildinformation, insbesondere einer Ausweis- oder Wertkarte. Das Verfahren ist dadurch gekennzeichnet, dass in einem ersten Verfahrensschritt ein Träger aus Polycarbonat hergestellt wird. In einem zweiten Schritt wird eine Oberfläche dieses Trägers zur Haftvermittlung behandelt. In einem dritten Schritt werden die farbigen Bildinformationen auf die behandelte Oberfläche aufgetragen. Das Auftragen erfolgt vorzugsweise mittels eines Thermoverfahrens und insbesondere mittels Thermosublimation oder Thermotransfer. Zur Haftvermittlung wird vorzugsweise der Träger lackiert, vorzugsweise mittels eines Siebdrucklackes. The invention also relates to a method for manufacturing a record carrier with colored image information, especially an ID card or prepaid card. The procedure is characterized in that in a first step a carrier is made of polycarbonate. In a second step, a surface of this support treated for mediation.
