Abstract

A forgery-proof flat article, for example, for the production of banking cards, credit cards, and the like, is provided with a security feature analogous to a watermark and is made of thermoplastic and elastomeric synthetic resins based on transparent, translucent, or colored sheets made by extrusion, calendering, blow-molding, or spread coating, or composite sheets therefrom, with an application of a colorant, capable of migrating, to the surface in the presence of a crosslinkable component in the flat article and/or in the colorant application. The colorant application, upon reaching the desired migration depth of the applied colorant, is fixed in the flat article by a crosslinking reaction. This flat article, by the use of two differently quickly migrating colorants, has a coloring showing on both sides of the flat article the security feature in congruence, this security feature appearing on the topside in the color of the more rapidly migrating colorant and, when the article is viewed while held up to the light, appearing in the form of the mixed color. Special effects are obtained in one embodiment of a composite flat article wherein one sheet side, treated with two different colorants, is bonded by laminating to a further sheet. After penetration of the colorants and fixation, the security feature is visible on both sides of the sheet and recognizable in the mixed color when the article is held up to the light and viewed in this way.

Description

Die Erfindung betrifft ein fälschungssicheres Flächengebilde aus Kunststoff und ein Verfahren zur Herstellung desselben der im Gattungsbegriff der Patentansprüche 1 und 7 beschriebenen Art.The invention relates to a forgery-proof sheet made of plastic and a method for producing the same of the type described in the preamble of claims 1 and 7.

Kreditkarten, Scheckkarten, Ausweise, Zeichnungen oder dergleichen, die auf Basis von Flächengebilden aus Kunststoff hergestellt werden, sind trotz verschiedener Sicherheitsvorkehrungen nicht ausreichend sicher vor unerlaubter Nachbildung oder nachträglicher Veränderung.Credit cards, check cards, ID cards, drawings or the like, which are made on the basis of flat structures made of plastic, are, despite various security measures, not sufficiently safe from unauthorized reproduction or subsequent changes.

Aber auch auf dem Verpackungssektor könnte es von Vorteil sein, eine Verpackungsfolie zu verwenden, die die Nachahmung erschwert. Hier ist besonders an eine Verwendung bei Schallplatten, Musikkassetten, Pharmazeutika oder Parfümerieartikel zu denken, die in zunehmendem Maße ohne Zustimmung des Herstellers der Originalartikel nachgeahmt werden.But it could also be advantageous in the packaging sector to use packaging film that makes it difficult to imitate. In particular, one should think of a use for records, music cassettes, pharmaceuticals or perfumery articles, which increasingly without Consent of the manufacturer of the original article to be imitated.

Bei Qualitätspapier für Schreibwaren oder für Wertpapiere ist ein wirkungsvolles und von jedermann ohne Spezialgeräte zu erkennendes Sicherheitsmerkmal das Wasserzeichen, das in der Draufsicht die Konturen hell (negativ) und in der Durchsicht die Konturen des gewählten Motivs bzw. Signums dunkel (positiv) erscheinen läßt.In the case of quality paper for stationery or securities, an effective security feature that can be recognized by anyone without special equipment is the watermark, which makes the contours light (negative) when viewed from above and the contours of the selected motif or sign dark (positive) when viewed through.

Es ist bekannt, eine, migrationsfähige Farbstoffe enthaltende, Lacklösung auf ein flächiges Gebilde aus einem migrationsfreudigen Kunststoff zu bringen und diese nach Erreichen der gewünschten Migrationstiefe durch eine Vernetzungsreaktion zu stoppen ( DE-PS 27 50 984 ). Nach diesem Verfahren werden insbesondere großflächige Produkte für dekorative Folien oder Beläge für den Fußboden oder Wände oder auch Formkörper hergestellt.It is known to apply a coating solution containing migration-capable dyes to a flat structure made of a migration-friendly plastic and to stop it by a crosslinking reaction after reaching the desired depth of migration (DE-PS 27 50 984). Large-area products for decorative foils or coverings for floors or walls or molded articles are produced in particular by this process.

Aufgabe dieser Erfindung ist es, ein Sicherheitsmerkmal für Flächengebilde aus Kunststoff vorzuschlagen, das einerseits nur schwierig nachgeahmt oder verändert und andererseits auf einfache und schnelle Weise auch von Laien identifiziert werden kann.The object of this invention is to propose a security feature for flat structures made of plastic, which on the one hand can only be imitated or modified with difficulty and on the other hand can also be identified in a simple and quick manner by laypersons.

Diese Aufgabe wird in vorteilhafter Weise durch die im Kennzeichen der Ansprüche 1 und ? angegebenen Merkmale gelöst.This object is advantageously achieved by the features of claims 1 and? specified features solved.

Nach Anspruch 1 erhält man eine durch einen Teil oder ggf. durch das gesamte Material hindurchgehende Einfärbung, die sowohl auf der Vorder- als auf der Rückseite des Flächengebildes deckungsgleich das gewählte Sicherheitsmerkmal entsprechend dem aufgebrachten Muster zeigt.According to claim 1 is obtained through a part or, if necessary, through the entire material, which congruently shows both on the front and on the back of the fabric the selected security feature according to the pattern applied.

Das Sicherheitsmerkmal ist auch nicht durch Kratzen oder Abschaben zu beseitigen, oder durch ein Lösungsmittel zu entfernen, wie es bei einem nur aufgedruckten Muster oder bei einer Unterschrift der Fall wäre. Ferner ist bei Untersuchung des Flächengebildes an den seitlichen Schnitt kanten im Querschnitt der erfindungsgemäßen Flächengebilde der Migrationskeil nachweisbar.The security feature is also not to be removed by scratching or scraping off, or removed by a solvent, as is the case with a pattern or printed only would be the case with a signature. Furthermore, the migration wedge is detectable when examining the fabric at the lateral cut edges in the cross section of the fabric according to the invention.

Ein wirkungsvolles, einem Wasserzeichen analoges, Sicherheitsmerkmal erhält man erfindungsgemäß, wenn man bei der Lacklösung zwei unterschiedlich schnell migrierende Farbstoffe verwendet, z.B. einen blauen und einen gelben. Wenn der gelbe Farbstoff der schneller migrierende Farbstoff ist, sieht man nach ausreichender Migrationszeit an einer Oberfläche des z.B. weiß oder opak eingefärbten Flächengebildes das gewählte Motiv in der Farbe gelb. In der Durchsicht erkennt man dasselbe Motiv jedoch in einem dunklen grün. Bei Erreichen der gewünschten Migrationstiefe des aufgetragenen Farbmittels im Flächengebilde wird in bekann ter Weise, z.B. durch Vernetzen fixiert.An effective, watermark-like, security feature is obtained according to the invention if two dyes migrating at different speeds are used in the coating solution, e.g. one blue and one yellow. If the yellow dye is the faster migrating dye, you can see on a surface of the e.g. white or opaque colored fabric, the selected motif in the color yellow. In the review, however, the same motif can be seen in a dark green. When the desired migration depth of the applied colorant in the fabric is reached, it is known that e.g. fixed by networking.

Die Migrationstiefe läßt sich auch so einstellen, daß man in der Aufsicht das Motiv nicht erkennt, sondern dieses erst in der Durchsicht deutlich würde. Besondere Effekte werden erzielt, wenn man eine Folienseite, die wie oben mit einem, zwei verschiedene Farbstoffe, nämlich gelb und blau, enthaltenden Farblack behandelt ist, durch Kaschieren mit einer weiteren Folie zu einem Verbundflächengebilde verbindet, und zwar in der Form, daß das aufgebrachte Sicherheitsmerkmal nun zwischen den beiden Folien liegt. Nach dem Migrationsvorgang, der durch Temperatureinwirkung beschleunigt werden kann, ist an beiden Oberflächen das Sicherheitsmerkmal in der Farbe gelb sichtbar. Nun ist es gleichgültig, von welcher Seite die Folie betrachtet wird, immer erscheint das Sicherheitsmerkmal in der Aufsicht gel und in der Durchsicht grün. Ein derartiges Verbundflächengebilde ist in der einzigen Figur 1 der Zeichnung mit den angegebenen Bedeutungen illustriert. Die Schnittkante zeig bei einem solchen Verbundflächengebilde in der Mitte einen blauen Farbkeil, der sich über grün nach gelb zu den Rändern hin verändert. Durch Vernetzen werden die Konturen des Farbkeils fixiert. Neben den üblichen Farbstoffen kann man auch übliche organische Lumineszenzfarbstoffe verwenden, z. B.

Figure imgb0001
organischen Lumineszenzfarbstoffe beschränkt ist. Mit diesen Farbstoffen kann man Verbundflächengebilde herstellen, die das gewählte Sicherheitsmerkmal bei Normallicht nur in der Durchsicht zeigen, bei UV-Licht bestimmter Wellenlängen das Motiv jedoch auch in der Aufsicht erscheinen lassen.The depth of migration can also be set so that one does not recognize the motive in the supervision, but would only become clear in the review. Special effects are achieved if a film side which has been treated as above with a color lacquer containing two different dyes, namely yellow and blue, is joined by lamination with a further film to form a composite sheet-like structure, in such a way that the applied one Security feature now lies between the two foils. After the migration process, which can be accelerated by the effects of temperature, the safety feature is visible in yellow on both surfaces. Now it does not matter which side the film is viewed from, the security feature always appears in the top view gel and in the view green. Such a composite sheet is illustrated in the single FIG. 1 of the drawing with the meanings given. With such a composite fabric, the cut edge shows a blue color wedge in the middle, which changes from green to yellow towards the edges. By networking the contours of the color wedge fixed. In addition to the usual dyes, conventional organic luminescent dyes can also be used, e.g. B.
Figure imgb0001
 organic luminescent dyes is limited. With these dyes, it is possible to produce composite fabrics which only show the selected security feature in normal light when viewed through, but also allow the motif to appear in supervision when viewed at certain wavelengths.

Grundsätzlich müssen bei der erfindungsgemäßen Herstellung dieser Wasserzeichen-analogen Merkmale nicht beide verwendeten Farbstoffe migrationsfähig sein.In principle, in the production of these watermark-like features according to the invention, it is not necessary for both of the dyes used to be capable of migration.

Es können auch Kombinationen von einem migrierfähigen organischen Farbstoff mit nicht oder sehr wenig migrierfähigen anorganischen oder organischen Pigmenten zum Einsatz kommen.Combinations of a migratable organic dye with inorganic pigments or organic pigments which are not or very little capable of migrating can also be used.

Als Verfahren zum Aufbringen der Farblacke sind alle Druck-, Walz-, Gieß-, Tauch- und Spritzverfahren geeignet.All printing, rolling, casting, dipping and spraying processes are suitable as processes for applying the colored lacquers.

Darüber hinaus kann man aber auch entsprechende Kugelschreiberpasten, Tinten, Tuschen, Minen oder dergleichen zur Aufbringung von Sicherheitsmerkmalen vorsehen. Hiermit wären nach Fixierung durch Vernetzung nicht zu entfernende Beschriftungen, Vermerke, Zeichnungen oder dergleichen auf Verbundflächengebilden nach der Erfindung möglich, die nicht einfach gefälscht, verändert oder manipuliert werden können. Bei Scheck- und Kreditkarten sowie bei Ausweiskarten aus Kunststoff wird so eine sichere Methode für eine nicht zu beseitigende Unterschrift angegeben. Anhand der Beispiele 1 bis 3 sind die technischen Wirkungen der erfindungsgemäßen Flächengebilde sowie das erfindungsgemäße Verfahren zur Herstellung der Flächengebilde erläutert.In addition, however, appropriate ballpoint pen pastes, inks, inks, refills or the like can be provided for applying security features. After fixation by networking, inscriptions, endorsements, drawings or the like on composite flat structures according to the invention, which cannot be simply forged, changed or manipulated, would hereby be possible. In the case of check and credit cards as well as plastic ID cards, this provides a secure method for a signature that cannot be removed. The technical effects of the fabrics according to the invention and the process according to the invention for producing the fabrics are explained using examples 1 to 3.

1Beispiel 1 1 Example 1

Folgende Rezeptur wird bei 130°C über 15 Minuten auf einem Walzwerk gemischt und homogenisiert.

Figure imgb0002
The following recipe is mixed and homogenized on a rolling mill at 130 ° C for 15 minutes.
Figure imgb0002

Das erhaltene Walzfell wird in einer Presse bei 140°C zu D,2 mm dicken Folien gepreßt. Im Siebdruckverfahren wird folgender Farblack gemustert aufgedruckt:

Figure imgb0003
The rolled skin obtained is pressed in a press at 140 ° C to D, 2 mm thick films. The following color varnish is patterned printed using the screen printing process:
Figure imgb0003

Nach dem Abtrocknen des Lackes wird aus dieser Folie in einer Presse bei 1500C mit einer weiteren unbedruckten Folie ein Laminat hergestellt. Hierbei kommt das aufgedruckte Motiv zwischen die beiden Folien. Die Preßzeit und damit die Verweilzeit bei 150°C beträgt 10 Minuten.After the paint has dried, a laminate is produced from this film in a press at 150 ° C. with a further unprinted film. Here the printed motif comes between the two foils. The pressing time and thus the residence time at 150 ° C is 10 minutes.

Die so erhaltene Verbundfolie zeigt das gewählte Motiv in einer gelben Farbe.The composite film thus obtained shows the selected motif in a yellow color.

Bei der Durchsicht erkennt man das gleiche Muster in schwarz.When looking through you can see the same pattern in black.

Im Querschnitt ist an der Schnittkante ein gelber Farbkeil zu erkennen. Der Migrationsvorgang wird durch Bestrahlung mittels einer Elektronenstrahlanlage mit einer Beschleunigungsspannung von 500 keV beendet. Es wurde eine Dosis von 1,5 Mrad angewendet.In cross-section, a yellow color wedge can be seen on the cut edge. The migration process is ended by irradiation using an electron beam system with an acceleration voltage of 500 keV. A dose of 1.5 Mrad was used.

Beispiel 2Example 2

Auf die Folie aus Beispiel 1 wird mit einem Kugelschreiber, der mit folgender Pasten-Rezeptur gefüllt ist, eine Unterschrift geleistet:

Figure imgb0004
A signature is made on the film from Example 1 using a ballpoint pen filled with the following paste recipe:
Figure imgb0004

Diese signierte Folie wird 15 Minuten einer Temperatur vor 100°C ausgesetzt. Danach wird die Folie beidseitig mit einer 250 keV Elektronenstrahlanlage mit einer Dosie von 2 Mrad bestrahlt, wodurch das Weitermigrieren der Farbstoffe beendet wird. An dieser Folie ist die Unterschrift dauerhaft durch die gesamte Folie eingefärbt. Sie ist auf der Rückseite in Spielgeschrift zu sehen.This signed film is exposed to a temperature above 100 ° C for 15 minutes. The film is then irradiated on both sides with a 250 keV electron beam system with a dose of 2 Mrad, which stops the dyes from migrating further. The signature on this film is permanently colored by the entire film. It can be seen in game font on the back.

Ohne Zerstörung der Folie ist diese Signierung nicht zu entfernen, wie dies z.B. bei einer normalen Kugelschreibe: paste durch Abwischen mit geeigneten Lösungsmitteln möglich wäre. Auch Abkratzen oder Abschaben würde nicht möglich sein.This marking cannot be removed without destroying the film, as e.g. with a normal ballpoint pen: paste by wiping with suitable solvents would be possible. Scratching or scraping would not be possible either.

Beispiel 3Example 3

Eine Folie wie in Beispiel 1 wird mit folgender Farblösung im Siebdruckverfahren dessiniert:

Figure imgb0005
A film as in Example 1 is screen-printed with the following color solution:
Figure imgb0005

Wie in Beispiel 1 wird kaschiert.Laminating is carried out as in Example 1.

Die Folie wird mit einer 500 keV Elektronenstrahlanlage durch eine Dosis von 2 Mrad vernetzt.The film is cross-linked with a 500 keV electron beam system with a dose of 2 Mrad.

Die so erhaltene Folie ist bei Normallicht uni weiß. Erst bei Betrachtung unter UV-Licht wird das zuvor aufgebrachte Motiv sichtbar. In der Durchsicht ist dieses Motiv sowohl bei Normal- als auch bei UV-Licht zu sehen.The film thus obtained is plain white under normal light. The previously applied motif only becomes visible when viewed under UV light. When looking through, this motif can be seen in both normal and UV light.
