Definitions
- the invention relates to a security paper with a Security element in the form of a thread or tape, the from a translucent plastic film with at least partial opaque coating and one Information in the form of visual and / or machine has legible characters or patterns.
- security threads secured against counterfeiting. Papers of this type are referred to below as security papers become.
- the security threads used for this consist of various materials in the form of Threads or tapes with a width of 0.4 to 10 mm. They mainly consist of plastic films, which metallic coated, printed, colored or even e.g. B. are provided with pigment-shaped substances.
- the security threads by selecting appropriate substances, magnetic, fluorescent, x-ray absorbing and others To give properties.
- Metallic coated threads have been used recently increasingly used for security papers. These threads, which are partially or entirely inside the Papers are arranged in striking light almost invisible. Because that through the top layer of paper urgent light rays are on the metallic Surface completely reflected and in the paper diffusely scattered. Such appear in transmitted light Threads, on the other hand, as black stripes that differ from theirs Stand out clearly from the surroundings. Threads of this type can pass through a imprint on the paper cannot be imitated.
- For Counterfeit protection has also been increased proposed such aluminum-coated security threads to be provided with a micro script (DE-A-14 46 851). In practice, however, this has turned out to be little expediently emphasized, since this font on the otherwise opaque security thread in transmitted light is not and is very difficult to see in reflected light. Self if such security threads, as in EP-A-0 059 056 described as so-called window threads in the paper is inserted, the microprint remains in the printed paper difficult to find.
- a security thread is known from EP-A-0 279 880 transparent film material known, on which metallic glossy micro characters are provided.
- the micro characters are, because of the complete Embedding the thread in the banknote, not in incident light recognizable. In transmitted light, however, are exclusive only the characters are recognizable as the security thread itself is transparent. The viewer so only the banknote is shown in transmitted light continuous lettering, because of the small size of the Characters, its embedding in the pulp and possibly a printed image above it is difficult can be found. The imitation of such a thread is on the other hand because of the small size of the micro characters difficult.
- Security thread becomes a translucent plastic film, which can be colored, with a full surface opaque, especially metallic coating provided in the recesses in the form of characters or Patterns are generated.
- the thread is in transmitted light as Dark streaks can be seen in the document while the Characters and patterns compared to their immediate surroundings, the opaque thread coating, and also opposite the wider environment, the documentary material, stand out clearly as bright, possibly colored areas.
- the thread is very easy to find in the document and the characters are always of the appropriate size readable even without tools.
- Such a thread is used as a window thread in a Introduced security paper, so he offers in the area the window an additional copy protection, since the metallic luster of the coating from a copier cannot be reproduced and therefore the copy of this Areas in black.
- the invention is based on the object Security paper with a thread or ribbon-shaped Manufacture security element that provides a high level of protection against counterfeiting offers, but at the same time good recognizability the security element and the signs guaranteed without technical aids.
- the invention Security paper a security thread consisting of a translucent plastic substrate with grid-like metal coating on.
- This can be, for example, a periodic stripe pattern that is related to the Direction of the thread any orientation can take.
- this security thread carries a particularly visually readable information that over several opaque, metallic areas as well as metal-free Intermediate areas extends. That is, the information which include any characters or patterns can lie as translucent metal-free Areas in front.
- This grid-like arrangement of the metal areas has the Advantage that the frequent metal / non-metal changes Imitations of the visual impression, if any are only possible using complex techniques.
- the information can be the characters and / or patterns also arranged alternately Put together opaque and translucent areas.
- the translucent ones are Share of information in the area of opaque background coating and the opaque pieces of information in the coating-free translucent intermediate areas, so that the information on the background pattern take off in contrast.
- the security element according to the invention offers like all metallized security threads, one good copy protection through the well-known incident light / transmitted light effect. Larger coherent metallic Surfaces appear as dark spots in reflected light Paper, so that with the known security elements This visual impression has already been tried imitate. Small metallic areas, like the one in the Metallic characters described in EP-A-0 279 880 are less noticeable in reflected light, but difficult to find even in transmitted light, so that a review this authenticity feature is difficult.
- the security element according to the invention is due to of the background pattern consisting of approx. 50% opaque areas easy to find and check in paper. Moreover, due to the grid-like Arrangement of the opaque areas and the associated areas frequent changes between opaque and non-opaque Areas imitations of visual impression in reflected light prevented or at least made very difficult.
- a security document according to the invention here a banknote into which a thread or ribbon-shaped Security element 2 in the form of a window thread is woven so that the thread in certain Distances, the so-called windows 3, directly to the Paper surface occurs.

- the embodiment shown in Fig. 2 consists of a transparent or at least translucent plastic substrate 3, the one with a striped Metallization 4 is provided. Over several of them A streak extends visually and / or mechanically readable information 5, which is due to the corresponding shaped recesses in the opaque stripes stands out from this background.
- the metallic stripes 4 can for example have a width of 200 microns and with respect to the running direction of the thread by 45 ° have inclined orientation while the font weight the contrasting information is 600 ⁇ m can.
- the example shown in Fig. 2 has one coating-free edge area 6, which during the Production of the threads in web form as a cutting tolerance serves and in particular as a window thread for a uniform appearance of the thread in the window area. On this edge area 6 can in the production of fully exposed or embedded threads are dispensed with.
- the orientation of the metallic strips is arbitrary selectable and in a further preferred embodiment 0 ° with respect to the running direction of the thread, as shown in Fig. 3. The same applies of course for the selected stripe widths and font weights.
- the information can also be opaque and translucent Areas that differ from their respective Lift off the surroundings, put them together. Such variants show FIGS. 4-8.
- Fig. 4 shows a similar background pattern as Fig. 2, d. H. opaque at 45 ° to the direction of the thread Metal strips with a width of 400 ⁇ m in the area of Signs have correspondingly shaped recesses 9. Inverse to this get the in the coating-free Information portions 7 an between areas opaque coating, which is also strip-shaped and has the same angular orientation.
- Fig. 5 shows the analog case for a parallel to Direction of the thread running stripe-shaped Background pattern.

Description
Die Erfindung betrifft ein Sicherheitspapier mit einem Sicherheitselement in Form eines Fadens oder Bandes, das aus einer lichtdurchlässigen Kunststoffolie mit zumindest teilweiser opaker Beschichtung besteht und das eine Information in Form von visuell und/oder maschinell lesbaren Zeichen oder Mustern aufweist.The invention relates to a security paper with a Security element in the form of a thread or tape, the from a translucent plastic film with at least partial opaque coating and one Information in the form of visual and / or machine has legible characters or patterns.
Banknoten und andere geldwerte Papiere wie Schecks, Aktien, Reiseschecks, Scheck- und Kreditkarten, aber auch Pässe und Identitätskarten werden häufig durch Einfügen oder Aufbringen von sogenannten Sicherheitsfäden gegen Fälschungen abgesichert. Papiere dieser Art sollen im folgenden als Sicherheitspapiere bezeichnet werden. Die hierfür verwendeten Sicherheitsfäden bestehen aus verschiedensten Materialien in Form von Fäden oder Bändern mit einer Breite von 0,4 bis 10 mm. Sie bestehen vorwiegend aus Kunststoffolien, welche metallisch beschichtet, bedruckt, eingefärbt oder auch z. B. mit pigmentförmigen Substanzen versehen sind. Darüber hinaus ist es auch bekannt, den Sicherheitsfäden durch Auswahl entsprechender Substanzen magnetische, fluoreszierende, röntgenabsorbierende und andere Eigenschaften zu verleihen.Banknotes and other monetary documents such as checks, Shares, travelers checks, check and credit cards, however Passports and identity cards are also frequently used Insertion or application of so-called security threads secured against counterfeiting. Papers of this type are referred to below as security papers become. The security threads used for this consist of various materials in the form of Threads or tapes with a width of 0.4 to 10 mm. They mainly consist of plastic films, which metallic coated, printed, colored or even e.g. B. are provided with pigment-shaped substances. In addition, it is also known the security threads by selecting appropriate substances, magnetic, fluorescent, x-ray absorbing and others To give properties.
Metallisch beschichtete Fäden werden in jüngster Zeit in zunehmendem Maß für Sicherheitspapiere eingesetzt. Diese Fäden, die teilweise oder ganz im Inneren des Papiers angeordnet werden, sind im auffallenden Licht nahezu unsichtbar. Denn die durch die obere Papierschicht dringenden Lichtstrahlen werden an der metallischen Oberfläche vollständig reflektiert und im Papier diffus gestreut. Im Durchlicht erscheinen derartige Fäden hingegen als schwarze Streifen, die sich von ihrer Umgebung deutlich abheben. Fäden dieser Art können durch einen Aufdruck auf das Papier nicht imitiert werden. Zur Erhöhung der Fälschungssicherheit wurde auch bereits vorgeschlagen, derartige aluminiumbedampfte Sicherheitsfäden mit einer Mikroschrift zu versehen (DE-A-14 46 851). Dies hat sich aber in der Praxis als wenig sinnvoll herausgestellt, da diese Schrift auf dem sonst undurchsichtigen Sicherheitsfaden im Durchlicht nicht und im Auflicht nur sehr schwer erkennbar ist. Selbst wenn derartige Sicherheitsfäden, wie in der EP-A-0 059 056 beschrieben, als sogenannte Fensterfäden in das Papier eingebracht werden, bleibt der Mikrodruck im bedruckten Papier schwer auffindbar.Metallic coated threads have been used recently increasingly used for security papers. These threads, which are partially or entirely inside the Papers are arranged in striking light almost invisible. Because that through the top layer of paper urgent light rays are on the metallic Surface completely reflected and in the paper diffusely scattered. Such appear in transmitted light Threads, on the other hand, as black stripes that differ from theirs Stand out clearly from the surroundings. Threads of this type can pass through a imprint on the paper cannot be imitated. For Counterfeit protection has also been increased proposed such aluminum-coated security threads to be provided with a micro script (DE-A-14 46 851). In practice, however, this has turned out to be little expediently emphasized, since this font on the otherwise opaque security thread in transmitted light is not and is very difficult to see in reflected light. Self if such security threads, as in EP-A-0 059 056 described as so-called window threads in the paper is inserted, the microprint remains in the printed paper difficult to find.
Aus der EP-A- 0 279 880 ist ein Sicherheitsfaden aus transparentem Folienmaterial bekannt, auf welchem metallisch glänzende Mikroschriftzeichen vorgesehen sind. Die Mikroschriftzeichen sind, wegen der vollständigen Einbettung des Fadens in der Banknote, im Auflicht nicht erkennbar. Im Durchlicht hingegen sind ausschließlich nur die Schriftzeichen erkennbar, da der Sicherheitsfaden selbst transparent ausgeführt ist. Dem Betrachter zeigt sich also im Durchlicht nur noch ein die Banknote durchziehender Schriftzug, der wegen der Kleinheit der Schriftzeichen, seiner Einbettung in die Papiermasse und eventuell einem darüberliegenden Druckbild nur schwer auffindbar ist. Die Nachahmung eines solchen Fadens ist dagegen wegen der geringen Größe der Mikroschriftzeichen erschwert.A security thread is known from EP-A-0 279 880 transparent film material known, on which metallic glossy micro characters are provided. The micro characters are, because of the complete Embedding the thread in the banknote, not in incident light recognizable. In transmitted light, however, are exclusive only the characters are recognizable as the security thread itself is transparent. The viewer so only the banknote is shown in transmitted light continuous lettering, because of the small size of the Characters, its embedding in the pulp and possibly a printed image above it is difficult can be found. The imitation of such a thread is on the other hand because of the small size of the micro characters difficult.
Bei einem weiteren aus der EP-A 0 330 733 bekannten Sicherheitsfaden wird eine lichtdurchlässige Kunststofffolie, die farbig ausgeführt sein kann, mit einer vollflächigen opaken, insbesondere metallischen Beschichtung versehen, in der Aussparungen in Form von Zeichen oder Mustern erzeugt werden. Der Faden ist im Durchlicht als dunkler Streifen im Dokument erkennbar, während sich die Schriftzeichen und Muster gegenüber ihrer direkten Umgebung, der opaken Fadenbeschichtung, und zusätzlich gegenüber der weiteren Umgebung, dem Dokumentenmaterial, als helle, eventuell farbige Flächen gut erkennbar abheben. Der Faden ist damit im Dokument sehr gut auffindbar und die Zeichen sind bei entsprechender Größe jederzeit auch ohne Hilfsmittel lesbar.In another known from EP-A 0 330 733 Security thread becomes a translucent plastic film, which can be colored, with a full surface opaque, especially metallic coating provided in the recesses in the form of characters or Patterns are generated. The thread is in transmitted light as Dark streaks can be seen in the document while the Characters and patterns compared to their immediate surroundings, the opaque thread coating, and also opposite the wider environment, the documentary material, stand out clearly as bright, possibly colored areas. The thread is very easy to find in the document and the characters are always of the appropriate size readable even without tools.
Wird ein derartiger Faden als Fensterfaden in ein Sicherheitspapier eingebracht, so bietet er im Bereich der Fenster einen zusätzlichen Kopierschutz, da der metallische Glanz der Beschichtung von einem Kopiergerät nicht reproduziert werden kann und die Kopie daher diese Bereiche schwarz wiedergibt.Such a thread is used as a window thread in a Introduced security paper, so he offers in the area the window an additional copy protection, since the metallic luster of the coating from a copier cannot be reproduced and therefore the copy of this Areas in black.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Sicherheitspapier mit einem faden- oder bandförmigen Sicherheitselement herzustellen, das einen hohen Fälschungsschutz bietet, gleichzeitig aber eine gute Erkennbarkeit des Sicherheitselements sowie der Zeichen ohne technische Hilfsmittel gewährleistet.The invention is based on the object Security paper with a thread or ribbon-shaped Manufacture security element that provides a high level of protection against counterfeiting offers, but at the same time good recognizability the security element and the signs guaranteed without technical aids.

In einer bevorzugten Ausführungsform weist das erfindungsgemäße Sicherheitspapier einen Sicherheitsfaden, bestehend aus einem lichtdurchlässigen Kunststoffsubstrat mit rasterartig ausgeführter Metallbeschichtung auf. Hierbei kann es sich beispielsweise um ein periodisches Streifenmuster handeln, das bezüglich der Laufrichtung des Fadens eine beliebige Orientierung einnehmen kann. Zusätzlich trägt dieser Sicherheitsfaden eine insbesondere visuell lesbare Information, die sich über mehrere opake, metallische Bereiche sowie metallfreie Zwischenbereiche erstreckt. Das heißt, die Informationen, welche beliebige Zeichen oder Muster umfassen können, liegen als lichtdurchlässige metallfreie Bereiche vor.In a preferred embodiment, the invention Security paper a security thread consisting of a translucent plastic substrate with grid-like metal coating on. This can be, for example, a periodic stripe pattern that is related to the Direction of the thread any orientation can take. In addition, this security thread carries a particularly visually readable information that over several opaque, metallic areas as well as metal-free Intermediate areas extends. That is, the information which include any characters or patterns can lie as translucent metal-free Areas in front.
Diese rasterartige Anordnung der Metallbereiche hat den Vorteil, daß durch den häufigen Metall-/Nichtmetall-Wechsel Nachahmungen des visuellen Eindrucks wenn überhaupt nur mittels aufwendiger Techniken möglich sind.This grid-like arrangement of the metal areas has the Advantage that the frequent metal / non-metal changes Imitations of the visual impression, if any are only possible using complex techniques.
Alternativ zu der vollständig lichtdurchlässigen Darstellung der Informationen können sich die Zeichen und/oder Muster auch aus alternierend angeordneten opaken und lichtdurchlässigen Bereichen zusammensetzen. In diesem Fall befinden sich die lichtdurchlässigen Informationsanteile im Bereich der opaken Hintergrundbeschichtung und die opaken Informationsanteile in den beschichtungsfreien lichtdurchlässigen Zwischenbereichen, so daß sich die Informationen zum Hintergrundmuster kontrastierend abheben. Durch diese Darstellungsart ergeben sich ebenfalls häufige Metall-/Nichtmetall-Wechsel, deren passergenaue Anordnung nur mit aufwendigen Techniken nachahmbar ist.As an alternative to the completely translucent representation the information can be the characters and / or patterns also arranged alternately Put together opaque and translucent areas. In this case, the translucent ones are Share of information in the area of opaque background coating and the opaque pieces of information in the coating-free translucent intermediate areas, so that the information on the background pattern take off in contrast. Through this type of representation there are also frequent metal / non-metal changes, their precise registration can only be imitated with complex techniques.
Im Papier bietet das erfindungsgemäße Sicherheitselement, wie alle metallisierten Sicherheitsfäden, einen guten Kopierschutz durch den bekannten Auflicht-/Durchlicht-Effekt. Größere zusammenhängende metallische Flächen erscheinen im Auflicht als dunkle Stellen im Papier, so daß bei den bekannten Sicherheitselementen bereits versucht wurde, diesen visuellen Eindruck zu imitieren. Kleine metallische Bereiche, wie die in der EP-A- 0 279 880 beschriebenen metallischen Schriftzeichen sind zwar im Auflicht weniger wahrnehmbar, aber auch im Durchlicht schwer auffindbar, so daß eine Überprüfung dieses Echtheitsmerkmals erschwert ist. Das erfindungsgemäße Sicherheitselement dagegen ist aufgrund des zu ca. 50 % aus opaken Bereichen bestehenden Hintergrundmusters leicht im Papier auffindbar und überprüfbar. Überdies können aufgrund der rasterartigen Anordnung der opaken Bereiche und der damit verbundenen häufigen Wechsel zwischen opaken und nicht opaken Bereichen Imitationen des visuellen Eindrucks im Auflicht verhindert oder zumindest stark erschwert werden.In the paper, the security element according to the invention offers like all metallized security threads, one good copy protection through the well-known incident light / transmitted light effect. Larger coherent metallic Surfaces appear as dark spots in reflected light Paper, so that with the known security elements This visual impression has already been tried imitate. Small metallic areas, like the one in the Metallic characters described in EP-A-0 279 880 are less noticeable in reflected light, but difficult to find even in transmitted light, so that a review this authenticity feature is difficult. The The security element according to the invention, however, is due to of the background pattern consisting of approx. 50% opaque areas easy to find and check in paper. Moreover, due to the grid-like Arrangement of the opaque areas and the associated areas frequent changes between opaque and non-opaque Areas imitations of visual impression in reflected light prevented or at least made very difficult.

Die Orientierung der metallischen Streifen ist beliebig wählbar und beträgt in einer weiteren bevorzugten Ausführungsform 0° bezüglich der Laufrichtung des Fadens, wie in Fig. 3 dargestellt. Analoges gilt selbstverständlich für die gewählten Streifenbreiten und Schriftstärken.The orientation of the metallic strips is arbitrary selectable and in a further preferred embodiment 0 ° with respect to the running direction of the thread, as shown in Fig. 3. The same applies of course for the selected stripe widths and font weights.
Auch muß es sich nicht notwendigerweise um ein streifenförmiges Hintergrundmuster handeln, sondern es können auch beliebige andere rasterartige Metallanordnungen eingesetzt werden, wie z. B. ein Punktraster oder ein Raster aus beliebig geformten geometrischen Figuren. Es ist lediglich darauf zu achten, daß die Ausdehnung der Metallbereiche und die Schriftgröße der Information so aufeinander abgestimmt sind, daß die Information zum Hintergrund kontrastiert und somit erkennbar ist. Neither does it necessarily have to be a strip-like one Act background pattern, but can also any other grid-like metal arrangements are used, such as. B. a grid or a Grid of arbitrarily shaped geometric figures. It you just have to make sure that the extension of the Metal areas and the font size of the information so are coordinated that the information on Background contrasts and is therefore recognizable.
Gemäß einer weiteren Ausführungsform der Erfindung können die Informationen auch aus opaken und lichtdurchlässigen Bereichen, die sich von ihrer jeweiligen Umgebung abheben, zusammensetzen. Derartige Varianten zeigen die Fig. 4 - 8.According to a further embodiment of the invention the information can also be opaque and translucent Areas that differ from their respective Lift off the surroundings, put them together. Such variants show FIGS. 4-8.
Fig. 4 zeigt ein ähnliches Hintergrundmuster wie Fig. 2,
d. h. um 45° zur Laufrichtung des Fadens geneigte opake
Metallstreifen der Breite 400 µm, die im Bereich der
Zeichen entsprechend geformte Aussparungen 9 aufweisen.
Invers hierzu erhalten die in den beschichtungsfreien
Zwischenbereichen liegenden Informationsanteile 7 eine
opake Beschichtung, die ebenfalls streifenförmig ausgebildet
ist und die gleiche Winkelorientierung aufweist.Fig. 4 shows a similar background pattern as Fig. 2,
d. H. opaque at 45 ° to the direction of the thread
Metal strips with a width of 400 µm in the area of
Signs have correspondingly shaped recesses 9.
Inverse to this get the in the coating-
Fig. 5 zeigt den analogen Fall für ein parallel zur Laufrichtung des Fadens verlaufendes streifenförmiges Hintergrundmuster.Fig. 5 shows the analog case for a parallel to Direction of the thread running stripe-shaped Background pattern.
Eine andere Alternative ist in Fig. 6 dargestellt. In
diesem Fall ist das Kunststoffsubstrat 3 in zwei
parallel zur Fadenlaufrichtung angeordnete Teilbereiche
untergliedert. Der obere Bereich umfaßt die Metallisierung
4, in welcher die lichtdurchlässigen Anteile 9 der
Information vorgesehen sind. Die opaken Informationsanteile
7 befinden sich in dem unteren beschichtungsfreien
Bereich 8 des Kunststoffsubstrats 3.Another alternative is shown in FIG. 6. In
In this case, the
Eine weitere Variation bietet Fig. 7. Hier ist das
Kunststoffsubstrat 3 mit zwei symmetrisch zur Fadenmitte
angeordneten entlang dem Faden verlaufenden Metallstreifen
4 versehen, die z. B. eine Breite von ca.
1,3 mm besitzen. Diese Streifen sind durch einen ca.
1 mm breiten beschichtungsfreien Bereich 8 voneinander
getrennt. Die diesem Untergrundmuster überlagerte Information
hat eine Schriftgröße von etwa 3 mm, eine
Schriftstärke von 600 µm und erstreckt sich über alle
drei Hintergrundbereiche. In den Metallbalken 4 werden
die Informationsanteile in Form von Aussparungen 9 dargestellt,
während die in dem beschichtungsfreien Bereich
8 befindlichen Anteile 7 aus opakem Beschichtungsmaterial
bestehen.Fig. 7 offers another variation. Here it is
Fig. 8 zeigt eine weitere Ausführungsform der zusammengesetzten
Informationen vor einem teilweise metallisierten
Hintergrund. In diesem Fall wird der Hintergrund von
metallischen Balken 4 gebildet, die schachbrettartig auf
dem Kunststoffsubstrat 3 angeordnet sind. Die lesbaren
Informationen setzen sich analog zu den oben beschriebenen
Varianten aus Aussparungen 9 und metallischen
Bereichen 7 zusammen und erstrecken sich in Querrichtung
des Fadens gesehen über mindestens ein Paar nebeneinander
angeordneter metallischer/metallfreier Bereiche.Fig. 8 shows another embodiment of the composite
Information in front of a partially metallized
Background. In this case, the background of
Es ist natürlich möglich, die metallisierten Informationsanteile
7 und die metallischen Hintergrundbereiche
4 mit verschiedenen Metallen unterschiedlicher Eigenfarbe
zu gestalten. Ganz generell können statt einer
Metallisierung oder metallischen Druckfarbe auch andere
bei Betrachtung im Durchlicht zur Umgebung farblich
und/oder im Grauton kontrastierende nichtmetallische
Schichten, wie z. B. deckende, vorzugsweise weiße Farbschichten,
metallisch glänzende Schichten, wie z. B.
Nitannitrid oder Interferenzschichten, Anwendung finden.
Auch interferenzpigmenthaltige Druckfarben sind denkbar.It is of course possible to use the metallized
Ebenso kann das Kunststoffsubstrat mit nichtdeckenden, vorzugsweise lasierenden Druckfarben in verschiedenen Farben und Tönungen versehen werden. Die Folie kann jedoch auch mit entsprechenden Farbmitteln so eingefärbt werden, daß in einem Teilbereich des visuell zugänglichen Spektrums die Transparenz erhalten bleibt. Durch die Verwendung lumineszierender Farben kann der visuelle Eindruck dieses Fadens noch weiter verbessert und effektvoller ausgeführt werden. Die Lumineszenzfarben können entweder im nicht angeregten Zustand farblos sein oder eine Körperfarbe besitzen, die sich vorzugsweise von der Farbe des Emissionslichts unterscheidet. Die Schriftzeichen oder Muster erscheinen dann erst im Anregungslicht farbig bzw. wechseln ihre Farbe, wenn der Faden z. B. unter UV-Licht betrachtet wird. Mehrere in unterschiedlichen Farben emittierende Lumineszenzstoffe erhöhen sowohl die gestalterische Möglichkeiten als auch die Fälschungssicherheit, da zur exakten Nachahmung die Analyse jedes einzelnen Lumineszenzstoffes notwendig ist. Diese Analyse kann in einfacher Weise noch weiter erschwert werden, indem die verschiedenen Lumineszenzfarben gemischt oder überlappend aufgedruckt werden.Likewise, the plastic substrate with non-covering, preferably translucent printing inks in different Colors and tints can be provided. The slide can but also dyed with appropriate colorants be that in a portion of the visually accessible The spectrum remains transparent. By the use of luminescent colors can be visual Impression of this thread is further improved and be executed more effectively. The luminescent colors can either be colorless when not excited or have a body color that is preferred differs from the color of the emission light. The Characters or patterns only appear in the Excitation light colored or change color when the Thread z. B. is viewed under UV light. Several in different colors emitting luminescent substances increase both the design possibilities as well the counterfeit security, since for exact imitation Analysis of each individual luminescent substance necessary is. This analysis can easily go further are made more difficult by the different luminescent colors mixed or overlapping printed.
Die Herstellung der beschriebenen Fadenvarianten kann, sofern keine Druckfarben benutzt werden, nach einem Waschverfahren oder einem anderen Demetallisierungsverfahren erfolgen, wie sie z. B. in der EP-A- 0 330 733 beschrieben sind, auf welche in diesem Zusammenhang ausdrücklich Bezug genommen wird.The production of the thread variants described can if no inks are used, after a Washing process or another demetallization process take place as z. B. in EP-A-0 330 733 to which are described in this context explicit reference is made.
