Abstract

The invention relates to a marking substance for security documents of the kind difficult to discern by counterfeiters. The preferred marking substance is polyethylene dioxythiophene polystyrene sulfonate and, more particularly, PEDT/PSS of the CPP105 formulation.

Description

Die Erfindung betrifft Merkmalsstoffe für Sicherheitsmerkmale in Dokumenten, Wertpapieren, Banknoten, Verpackungen und Waren nach dem Oberbegriff des Anspruchs 1.The invention relates to feature substances for security features in documents, securities, Banknotes, packaging and goods according to the preamble of claim 1.

Die Papierstoffbahnen für Dokumente, Wertpapiere, Banknoten, Verpackungen und für Waren werden zur Erhöhung der Fälschungssicherheit mit Merkmalsstoffen versehen. Bislang verwendete lichtaktive Merkmalsstoffe sind gegenwärtig auf dem freien Markt erhältlich, so daß Fälscher in der Lage sind, die mit ihnen hergestellten Sicherheitsmerkmale nachzustellen.
In der EP 753 623 wird in diesem Zusammenhang ein Sicherheitsblatt mit einem elektrisch leitendem Element beschrieben. Das Sicherheitsblatt besteht aus einer Trägermatrix mit einer Faserstruktur und das leitende Element ist ein Sicherheitsfaden in Form einer Folie. Die Folie ist mit einem elektrisch leitendem Polymer aus der Gruppe der Polythiophene beschichtet. Das elektrisch leitende Polymer wird in flüssiger oder dispergierter Form auf die Folie aufgetragen.
In der US 5,112,672 wird ein Sicherheitsdokument mit einem eingebettetem elektrisch leitenden Sicherheitsfaden beschrieben. Der Sicherheitsfaden besitzt eine Metallbeschichtung die zur Überbrückung von Unterbrechungen mit einem elektrisch leitendem Polymer versehen ist.
In der US 5,419,424 wird eine Prüfeinrichtung für den Sicherheitsfaden in Banknoten dargestellt. Die Prüfeinrichtung besitzt Sensorelektroden, die den Sicherheitsfaden mittels kapazitiver Kopplung detektieren.
In der DE 43 34 797 wird ein Verfahren zur Herstellung fälschungssicherer Dokumente sowie ein Verfahren zu deren Prüfung aufgezeigt. Die Dokumente enthalten ein Gitterwerk aus Metalldrähten, die an ihren Kreuzungspunkten kontaktiert werden. The paper webs for documents, securities, banknotes, packaging and for goods are provided with feature substances to increase the security against counterfeiting. Previously used light-active feature substances are currently available on the open market, so that counterfeiters are able to reproduce the security features produced with them.
In this context, EP 753 623 describes a safety sheet with an electrically conductive element. The safety sheet consists of a carrier matrix with a fiber structure and the conductive element is a security thread in the form of a film. The film is coated with an electrically conductive polymer from the group of polythiophenes. The electrically conductive polymer is applied to the film in liquid or dispersed form.
US 5,112,672 describes a security document with an embedded electrically conductive security thread. The security thread has a metal coating which is provided with an electrically conductive polymer to bridge interruptions.
In US 5,419,424 a test device for the security thread in banknotes is shown. The test device has sensor electrodes that detect the security thread by means of capacitive coupling.
DE 43 34 797 shows a method for producing counterfeit-proof documents and a method for checking them. The documents contain a grid of metal wires that are contacted at their crossing points.

In der EP 839 950 wird ein Verfahren zum Einlagern von Substanzen in eine laufende Faserbahn beschreiben. Die Substanzen werden im/oder vor dem Stoffauflauf in die Faserstoffsuspension eingeleitet. Die Einleitung geschieht an mehreren über die Breite der Faserbahn verteilten Stellen und geschieht mindestens an einer Stelle intermittierend.
Um in dieser Situation für Fälscher technologische Hürden aufzubauen, entstanden komplizierte Lösungen unter Verwendung lichtaktiver Merkmalsstoffe, bei denen - wie in DE. 196 53 423 beschrieben - humanvisuell nicht erkennbare, lichtabsorbierende Merkmalsstoffe zusätzlich Verwendung finden. Auf diese Weise entstehen beispielsweise während einer Prüfung unter dem Einfluß von IR-Licht Druckbilder mit auffälligen Fehlstellen.
Zur Erhöhung der Fälschungssicherheit werden weiter Merkmalsstoffe in einer definierten Verteilung auf die Papierbahn aufgebracht, um die Echtheit eines Dokuments maschinell lesbar zu machen. Nach der DE 197 14 519 werden dafür humanvisuell nicht erkennbare Merkmalsstoffe eingesetzt, die in linienförmig ausgeführten Markierungen ein visuelles Druckbild überlagern. Der verwendete Merkmalsstoff soll aufgrund einer physikalischen Eigenschaft maschinell nachweisbar sein. Unter anderen wird als eine derartige physikalische Eigenschaft auch die elektrische Leitfähigkeit genannt, jedoch wird ein derartiger, humanvisuell nicht erkennbarer Merkmalsstoff nicht offenbart.
Ein gegenwärtig bei Banknoten verbreitet eingesetztes Sicherheitsmerkmal wird durch einen Folienaufbau verkörpert, der aus mindestens einer Trägerfolie und einer auf die Trägerfolie aufgebrachten Metallisierung besteht. Ein sogenannter Sicherheitsfaden wird entweder vollständig oder mit Fenstern in die Papierbahn eingebettet. Ursprilnglich diente ein solcher Sicherheitsfaden einschließlich erkennbarer demetallisierter Stellen in Form von Zeichen oder Buchstaben nur zur humanvisuellen Prüfung. In dem Bestreben einer Verbesserung der Fälschungssicherheit wurde eine zusätzliche Prüfung der elektrischen Leitfähigkeit der Metallisierung in Betracht gezogen. Eine Verwirklichung dieser Absicht scheiterte bislang daran, daß einerseits die Banknoten in ihrem Gebrauch einer hohen mechanischen Beanspruchung unterliegen, beispielsweise durch Knicken und Falten durch den Benutzer, aber auch durch Biegen in Geldautomaten und Zählmaschinen. Zum anderen unterliegt der Folienaufbau auch schon während des technologischen Prozesses der Papierherstellung infolge Spannens und Biegens einer erheblichen Belastung. Als Folge dessen treten in der Metallisierung zufällig verteilt feine Haarrisse auf, die jegliches Meßergebnis unsicher und nicht reproduzierbar machen. Um Fälschungen dieses Sicherheitsmerkmals aber zu begegnen, ist in den Prüfvorrichtungen von Bankautomaten nicht nur die Präsenz einer Metallisierung nachzuweisen, sondern die Echtheit ist aufgrund eines bestimmten Meßwertes der Leitfähigkeit zu erkennen. Dieses Problem wird grundsätzlich auch nicht dadurch gelöst, wenn-wie in DE 43 44 553 und EP 659 587 vorgeschlagen - anstelle des Aufdampfens der Metallisierung im Hochvakuum metallisch wirkende Druckfarben eingesetzt werden.EP 839 950 describes a method for storing substances in a running fiber web. The substances are introduced into the fiber suspension in / or before the headbox. The introduction takes place at several locations distributed over the width of the fiber web and occurs intermittently at least at one location.
In order to create technological hurdles for counterfeiters in this situation, complicated solutions were created using light-active feature substances, in which - as in DE. 196 53 423 - light-absorbing feature substances that are not visually recognizable by humans can also be used. In this way, for example, during an inspection under the influence of IR light, printed images with noticeable defects are created.
In order to increase the security against counterfeiting, feature substances are further applied to the paper web in a defined distribution in order to make the authenticity of a document machine-readable. According to DE 197 14 519, human-visually not recognizable feature substances are used, which overlay a visual print image in line-shaped markings. The feature substance used should be detectable by machine due to a physical property. Among others, the electrical conductivity is also mentioned as such a physical property, but such a feature substance, which cannot be recognized by human vision, is not disclosed.
A security feature currently used in banknotes is embodied by a film structure consisting of at least one carrier film and a metallization applied to the carrier film. A so-called security thread is either completely or embedded in the paper web with windows. Such a security thread, including recognizable demetallised points in the form of characters or letters, was originally only used for human-visual inspection. In an effort to improve counterfeit protection, an additional test of the electrical conductivity of the metallization was considered. A realization of this intention has so far failed because, on the one hand, the banknotes are subjected to high mechanical stresses in their use, for example by kinking and folding by the user, but also by bending in ATMs and counting machines. On the other hand, the film structure is subject to considerable stress even during the technological process of paper production as a result of tensioning and bending. As a result, fine hairline cracks occur randomly in the metallization, which make any measurement result uncertain and not reproducible. However, in order to counterfeit this security feature, not only the presence of a metallization must be verified in the test devices of automated teller machines, but the authenticity can be recognized on the basis of a certain measured value of the conductivity. In principle, this problem is also not solved if — as proposed in DE 43 44 553 and EP 659 587 — instead of vapor deposition of the metallization in a high vacuum, metallic inks are used.

Da die elektrische Leitfähigkeit eine der wesentlichsten .Eigenschaften von Metallen ist, scheint es naheliegend zu sein, daß Fälscher die elektrische Leitfähigkeit einer Metallisierung vermuten. Es stehen gegenwärtig sogar ausreichend technologische Ausrüstungen wohlfeil zur Verfügung, um richtige Metallisierungen einschließlich ihrer bildhaften Gestaltung als Fälschung eines Sicherheitsmerkmals in Dokumente, Wertpapiere, Banknoten, Verpackungen oder Waren einzubringen. Da aber die elektrische Leitfähigkeit ein schnell und sicher nachweisbarer Prüfparameter ist, besteht vorerst nicht das Verlangen, auf dieses Sicherheitsmerkmal zu verzichten. Nachteilig ist außerdem, daß die humanvisuell sichtbare Metallisierung in ihren Eigenschaften kaum variabel ist, da sie für den Großteil der Benutzer als ein konstantes und immer in gleicher Weise erkennbares Sicherheitsmerkmal dienen soll. Schließlich sind in die Geheimnisse dieses humanvisuell erkennbaren Sicherheitsmerkmals eine relativ große Anzahl von Personen in Verbindung mit dessen Herstellung und Prüfung eingeweiht, so daß allein von der Größe und Unüberschaubarkeit dieses Personenkreises ein Gefährdungspotential ausgeht.Since electrical conductivity is one of the most essential properties of metals, seems it is obvious that counterfeiters suspect the electrical conductivity of a metallization. Sufficient technological equipment is currently cheaply available, about correct metallizations including their pictorial design as a fake one Security feature in documents, securities, banknotes, packaging or goods contribute. But because the electrical conductivity is quickly and reliably detectable Test parameter, there is initially no desire to approach this security feature dispense. Another disadvantage is that the human-visually visible metallization in their Properties is hardly variable as it is considered a constant and for the majority of users Always serve identifiable security feature. Finally, in the A relatively large number of secrets of this human-visually recognizable security feature inaugurated by people in connection with its manufacture and testing, so that only by the size and complexity of this group of people poses a potential hazard.

Es ist somit Aufgabe der Erfindung, einen elektrisch leitenden Merkmalsstoff vorzuschlagen, bei denen die vorgenannten Nachteile nicht auftreten. Es ist weiterhin auch Aufgabe der Erfindung, solche Merkmalsstoffe vorzuschlagen, die zur Erhöhung der Fälschungssicherheit beitragen, weil die Notwendigkeit entstanden ist, ein weiteres, leicht variierbares Sicherheitsmerkmal zu schaffen, das weniger die Aufmerksamkeit auf sich lenkt als die humanvisuell erkennbare Metallisierung, beziehungsweise ein Sicherheitsmerkmal an wechselnden Stellen vorzuschlagen, an denen es nicht vermutet wird und nur mit äußerst präzise arbeitender Prüftechnik feststellbar ist. Die vorliegende Erfindung betrifft die Verwendung eines Polyethylendioxithiophenpolystyrolsulfonat (PEDT/PSS) als ein elektrisch leitender Merkmalstoff für Sicherheitsmerkmale für Dokumente, Wert papiere, Banknoten und Produkte. Diese der Sicherheit dienenden Merkmale und Elemente werden direkt oder in Verbindung mit anderen in die Papierstoffbahn einzubringenden Sicherheitsmerkmalen, wie Sicherheitsfäden, in die Papierstoffbahn integriert. It is therefore an object of the invention to propose an electrically conductive feature substance who do not experience the aforementioned disadvantages. It is also an object of the invention propose such feature substances that contribute to increasing the security against counterfeiting, because the need has arisen to add another, easily variable security feature create that attracts less attention than the human-visually recognizable Metallization, or to propose a security feature in changing places, where it is not suspected and can only be determined with extremely precise testing technology is. The present invention relates to the use of a Polyethylene dioxithiophene polystyrene sulfonate (PEDT / PSS) as one electrically conductive feature material for security features for Documents, securities, banknotes and products. These security features and elements are used directly or in conjunction with other security features to be incorporated into the paper web, such as security threads, integrated into the paper web.

Erfindungsgemäß wird diese Aufgabe durch die Kennzeichen und Merkmale des Anspruchs 1 sowie deren spezielle in den Unteransprüchen dargelegte Ausführungsformen gelöst.According to the invention, this object is achieved by the characteristics and features of claim 1 as well as their special embodiments set out in the subclaims.

Die erfindungsgemäße Lösung gewährt den Vorteil, dass das gefundene Polyethylendioxithiophenpolystyrolsulfonat (PEDT/PSS) in Verbindung mit Sicherheitspapier mit verdeckten, detektierbaren Merkmalen auszustatten, die humanvisuell nicht erkennbar sind und deren homogenes oder partielles Vorhandensein zu prüfen ist. Zugleich ergibt sich in überraschender Weise der Vorteil eines kontinuierlich ablaufenden, zeitsparenden und kostengünstigen Verfahrens zur Einbringung von Merkmalsstoffen und Sicherheitsmerkmalen in Papierbahnen und durch die hervorragenden stofflichen Eigenschaften des Polyethylendioxithiophenpolystyrolsulfonat (PEDT/PSS), der guten Verträglichkeit bei der Verbindung mit der Papierstoffsuspension.The solution according to the invention affords the advantage that the polyethylene dioxithiophene polystyrene sulfonate found (PEDT / PSS) in connection with security paper with equip hidden, detectable features that are not visually recognizable and their homogeneous or partial presence must be checked. At the same time it results in surprisingly the advantage of a continuous, time-saving and Inexpensive method for the introduction of feature substances and security features in Paper webs and the excellent material properties of polyethylene dioxithiophene polystyrene sulfonate (PEDT / PSS), the good compatibility with the connection with the pulp suspension.

    Beispiel 1:Example 1:

    In Fig. 1 und 2 wird dargestellt, wie ein partieller Auftrag des gefundenen Polyethylendioxithiophenpolystyrolsulfonat (PEDT/PSS) durch genau. über der Papierstoffbahn 6 positionierten Dosiereinrichtungen realisiert wird. Die Voraussetzung für eine gleichmäßige Versorgung der Dosiereinrichtungen mit dem Merkmalsstoff ist eine ständige Zirkulation des Papierbreis durch Pumpen 20 im gesamten Rohrsystem einschließlich des Vorratsbehälters 26 für den Merkmalsstoff zur partiellen Integration. Mittels einer Anordnung von Dosiereinrichtungen, bestehend jeweils aus einem Auslaufrohr 17 mit einem automatischen Ventil 19 wird der Merkmalsstoff partiell auf die Papierstoffbahn 6 aufgebracht beziehungsweise in diese integriert. Dadurch entstehen in Abhängigkeit von der Steuerung linienförmig kontinuierliche Prüfzonen 14a, diskontinuierliche Prüfzonen 14b oder punktuelle Prüfzonen 14c. Siehe dazu auch Fig. 9. Durch das Schneiden der Papierstoffbahn 6 zu Blattgut erhält man partielle Prüfzonen 14 mit dem Merkmalsstoff. Diese können über die gesamte Blattbreite oder Blattlänge verlaufen oder abschnittsweise in der Blattlänge oder -breite vorhanden sein. Die Breite der Linien oder Linienabschnitte ist dem Auflösungsvermögen der Scannersensoren 10; 11anzupassen. Vorzugsweise wird eine Linienbreite von 2 mm gewählt.
    Bei der Verwendung elektrisch leitender Polymere ergibt sich der Vorteil, daß diese Polymere eine gute Verträglichkeit zu den anderen Inhaltsstoffen des Papierbreis besitzen. Die Integration in den Papierstoff ist deshalb wesentlich unkomplizierter als bei festen Merkmalsstoffen, da die elektrisch leitenden Polymere auch in flüssiger Form zur Verfügung stehen. Die benötigten Konzentrationen gestatten eine nahezu transparente elektrisch leitende Markierung.    In Fig. 1 and 2 is shown as a partial order of the found Polyethylendioxithiophenpolystyrolsulfonat (PEDT / PSS) carefully. Dosing devices positioned above the paper web 6 are realized. The prerequisite for a uniform supply of the dosing devices with the feature substance is a constant circulation of the pulp by pumps 20 in the entire pipe system including the reservoir 26 for the feature substance for partial integration. By means of an arrangement of metering devices, each consisting of an outlet pipe 17 with an automatic valve 19 , the feature substance is partially applied to the paper web 6 or integrated into it. As a result, depending on the control, continuous test zones 14a , discontinuous test zones 14b or punctiform test zones 14c are formed . See also Fig. 9 . By cutting the paper web 6 into sheet material, partial test zones 14 with the feature substance are obtained. These can run over the entire sheet width or sheet length or can be present in sections in the sheet length or width. The width of the lines or line sections is the resolution of the scanner sensors 10; 11 adapt. A line width of 2 mm is preferably selected.
    The advantage of using electrically conductive polymers is that these polymers have good compatibility with the other ingredients in the pulp. The integration into the paper stock is therefore much less complicated than with solid feature fabrics, since the electrically conductive polymers are also available in liquid form. The concentrations required permit an almost transparent, electrically conductive marking.

    Beispiel 2:Example 2:

    Anhand der Fig. 8 wird mittels der Prägewalze 5 und der Merkmalsstoffübertragungswalze 7 ein Abdruck des PEDT/PSS auf der Papierstoffbahn 6 erzeugt. Der Abdruck der Prägesegmente 25 entspricht der bildlichen Darstellung der elektrisch leitenden Prüfzone in Form des Wasserzeichens 9.With reference to the Fig. 8 by means of the embossing roller 5 and the feature substance transfer roller 7 produces an impression of the PEDT / PSS on the pulp web 6. The impression of the embossed segments 25 corresponds to the pictorial representation of the electrically conductive test zone in the form of the watermark 9 .

    Beispiel 3:Example 3:

    In den Fig. 1 und 2 wird dargestellt, daß die Prüfzonen 14 in der Papierstoffbahn 6 auf das homogene beziehungsweise partielle Vorhandensein des Merkmalsstoffs kontrolliert werden. Das dabei gewonnene Prüfergebnis beeinflußt über das Steuerteil 18 die automatischen Ventile 19 in den Auslaufrohren 17. 1 and 2 show that the test zones 14 in the paper web 6 are checked for the homogeneous or partial presence of the feature substance. The test result obtained influences the automatic valves 19 in the outlet pipes 17 via the control part 18 .

    Wie bereits ausgeführt, ist in den Fig. 7, 7a, 8a, 9 und 10 die Prüfung in verschiedenen Anwendungen mit den entsprechenden Signalbildern dargestellt.As already stated, the test in various applications with the corresponding signal images is shown in FIGS. 7, 7a, 8a, 9 and 10 .

    In Fig. 7 wird anhand eines Wasserzeichens im Prägebereich 24 dargestellt, wie die Prüfung der elektrischen Leitfähigkeit des Papiers als eine Referenzprüfung zu der Prüfung der bildhaften Gestaltung des Wasserzeichens ausgeführt wird.
    Das Papier mit dem Wasserzeichen durchläuft in Pfeilrichtung nacheinander eine Anordnung optischer Scannersensoren 10 und eine weitere Anordnung kapazitiver Scannersensoren 11. Das dazugehörige Signalbild zeigt den übereinstimmenden Spannungsverlauf der optischen Scannersensoren 10 und der kapazitiven Scannersensoren 11, hier dargestellt als eine Funktion der Kanalzahl.
    Wie Fig. 7a zeigt, werden auch hier die Sensorkanäle wie oben beschrieben im Wechsel angesteuert.    In FIG. 7, a watermark in the embossing area 24 shows how the test of the electrical conductivity of the paper is carried out as a reference test for the test of the pictorial design of the watermark.
    The paper with the watermark successively passes through an arrangement of optical scanner sensors 10 and a further arrangement of capacitive scanner sensors 11 in the direction of the arrow. The associated signal image shows the corresponding voltage profile of the optical scanner sensors 10 and the capacitive scanner sensors 11 , shown here as a function of the number of channels.
    As FIG. 7a shows, the sensor channels are controlled alternately as described above.

    In Fig. 9 und 10 wird die Prüfung von linienförmig auf Papier aufgetragenen Merkmalsstoff sowie die dabei entstehenden Signalbilder 23 gezeigt.
    In Fig. 9a enthält das Papier eine Prüfzone 14a mit einem kontinuierlichen, linienförmigen Auftrag des Merkmalsstoffes. Beim Durchlaufen der Prüfanordnung, bestehend aus den optischen Sensoren 13 und den kapazitiven Scannersensoren 11, entsteht ein entsprechender kontinuierlicher Spannungsverlauf U = f (t) im Signalbild 23.
    In Fig. 9b ist der Auftrag des Merkmalsstoffes in der Prüfzone 14b in regelmäßigen Abständen unterbrochen. Während der Prüfung entsteht ein Signalbild 23 mit entsprechenden regelmäßigen Sprüngen im Spannungsverlauf U = f (t).
    In Fig. 9c ist der Auftrag in der Prüfzone 14c in unregelmäßigen Abständen unterbrochen. Auch das spiegelt sich in dem sich ergebenden Signalbild 23 wider.    9 and 10 show the testing of feature substance applied in the form of a line on paper and the signal images 23 which are produced in the process.
    9a, the paper contains a test zone 14a with a continuous, linear application of the feature substance. When the test arrangement, consisting of the optical sensors 13 and the capacitive scanner sensors 11 , is run through, a corresponding continuous voltage profile U = f (t) arises in the signal image 23 .
    9b, the application of the feature substance in the test zone 14b is interrupted at regular intervals. During the test, a signal image 23 is generated with corresponding regular jumps in the voltage curve U = f (t).
    In Fig. 9c the order in the test zone 14c is interrupted at irregular intervals. This is also reflected in the resulting signal image 23 .

    Beispiel 4:Example 4:

    Im folgenden wird anhand der Fig. 11 bis 14 die Anwendung des elektrisch leitenden Merkmalsstoffes bei einem in die Papierstoffbahn 6 einzubringenden Folienaufbaus erläutert.
    Der Folienaufbau des in eine Papierbahn einzubringenden Sicherheitsmerkmals enthält eine Trägerfolie 28; 28', beispielsweise aus Polypropylen, mit einer Dicke von vorzugsweise 40 µm. Die auf die Trägerfolie 28; 28', beispielsweise durch Bedampfen oder Sputtern, aufgebrachte Metallisierung 29 weist eine zusätzliche Dicke von etwa 2 nm auf.    The use of the electrically conductive feature substance in a film structure to be introduced into the paper web 6 is explained below with reference to FIGS . 11 to 14 .
    The film structure of the security feature to be introduced into a paper web contains a carrier film 28; 28 ' , for example made of polypropylene, with a thickness of preferably 40 microns. The on the carrier film 28; 28 ', for example by vapor deposition or sputtering, applied metallization 29 comprises an additional thickness of about 2 nm on.

    Die Metallisierung 29 enthält demetallisierte Stellen, beispielsweise in Form von Buchstaben oder Zahlen, die humanvisuell im Durchlicht für den Benutzer erkennbar sind. Die Demetallisierung erstreckt sich abschnittsweise bis an den Rand der Trägerfolie 28; 28'. Auf ihrer anderen Seite ist die Trägerfolie 28; 28' mit einer weiteren Schicht 30 aus dem PEDT/PSS spezielle PEDT/PSS (Polyethylendioxythiophenpolystyrolsulfonat) nach der Formulierung CPP105, ist in einer Dicke von 1 µm bis 2 µm auf die Trägerfolie 28; 28' aufgetragen. Durch das The metallization 29 contains demetallized points, for example in the form of letters or numbers, which can be recognized by the user in human-visually transmitted light. The demetalization extends in sections to the edge of the carrier film 28; 28 ' . On its other side is the carrier film 28; 28 ' with a further layer 30 made of the PEDT / PSS special PEDT / PSS (polyethylene dioxythiophene polystyrene sulfonate) according to the formulation CPP105, is on the carrier film 28 in a thickness of 1 μm to 2 μm ; 28 ' plotted. By the

    Hinzufügen der weiteren Schicht 30 tritt also eine völlig zu vernachlässigende Dickenzunahme ein. Der als Sicherheitsmerkmal in eine Papierbahn eingebrachte Folienaufbau mit dem erfindungsgemäßen Merkmalsstoff beeinträchtigt also durch seine geringfügig veränderte Dicke in keiner Weise die aus der Papierbahn angefertigten Dokumente oder Banknoten, selbst in einem Stapel von beträchtlicher Höhe. Ebensowenig wird das Papier an der Einbettungsstelle des Sicherheitsmerkmals durch eine vergrößerte Dicke geschwächt.
    Die beispielsweise durch Bedampfen oder Sputtern auf die Trägerfolie 28; 28' aufgebrachte Metallisierung 29 ist nur wenige Atomlagen stark und daher in Abhängigkeit von der Oberflächenstruktur der Trägerfolie relativ spröde. Beim Falten, Biegen oder Knicken treten in zufälliger Weise verteilte Haarrisse auf, die das beabsichtigte Messen der Leitfähigkeit von vorgegebenen Abschnitten der Metallisierung 29 unmöglich machen. Dagegen ist die weitere Schicht 30 biegsam und elastisch und weist gegenüber der Metallisierung 29 in Abhängigkeit von der Oberflächenstruktur der Trägerfolie 28; 28' eine weit höhere Dehnbarkeit auf. Auch beim Biegen, Knicken und Falten, beispielsweise einer Banknote, tritt keine Unterbrechung der weiteren Schicht 30 ein. Die beispielsweise in Bankautomaten vorhandenen Prüfvorrichtungen erfassen nunmehr für vorgegebene Abschnitte des Sicherheitsmerkmals einen Meßwert der Leitfähigkeit aus der nach dem bekannten Stand der Technik vorgesehenen Metallisierung 29 mit möglicherweise vorhandenen Haarrissen und aus der zu der Metallisierung 29 parallelgeschalteten, relativ hochohmigen weiteren Schicht 30.    Adding the additional layer 30 thus leads to a completely negligible increase in thickness. The film structure with the feature substance according to the invention, which is introduced into a paper web as a security feature, does not in any way affect the documents or bank notes made from the paper web, even in a stack of considerable height, due to its slightly changed thickness. Nor is the paper weakened by an increased thickness at the embedding point of the security feature.
    The for example by vapor deposition or sputtering onto the carrier film 28; 28 ' applied metallization 29 is only a few atomic layers thick and therefore relatively brittle depending on the surface structure of the carrier film. Randomly distributed hairline cracks occur during folding, bending or kinking, making the intended measurement of the conductivity of predetermined sections of the metallization 29 impossible. In contrast, the further layer 30 is flexible and elastic and points towards the metallization 29 depending on the surface structure of the carrier film 28; 28 ' a much higher elasticity. Even when bending, kinking and folding, for example a bank note, the further layer 30 is not interrupted. The test devices present in automated teller machines, for example, now record a measured value of the conductivity for the given sections of the security feature from the metallization 29 provided according to the known prior art with possibly existing hairline cracks and from the relatively high-resistance layer 30 connected in parallel with the metallization 29 .

    Beispiel 5:Example 5:

    Eine bevorzugte Ausführung des Folienaufbaus mit dem erfindungsgemäßen Merkmalsstoff für ein Sicherheitsmerkmal, beispielsweise in einer Banknote, ist in Fig. 11 dargestellt. Fig. 11 zeigt die Trägerfolie 28, auf deren einer Seite die Metallisierung 29 aufgebracht ist. Die andere Seite der Trägerfolie 28 trägt die weitere Schicht 30 aus dem elektrisch leitenden Polymer.
    Das Aufbringen der weiteren Schicht 30 auf die Trägerfolie 28 geschieht nach üblichen technologischen Verfahren, beispielsweise durch ein Kalandrieren. Es entsteht somit eine Verbund-Folie, auf die anschließend die Metallisierung 29, beispielsweise durch Bedampfen, aufgebracht wird.
    Es ist selbstverständlich auch möglich, die weitere Schicht 30 aus dem elektrisch leitenden Polymer nach dem Bedampfen der Trägerfolie 28 auf die Metallisierung 29 aufzubringen. Bei einem derartigen Folienaufbau geht von der weiteren Schicht 30 eine gewisse Schutzwirkung für die Metallisierung 29 aus.    A preferred embodiment of the film structure with the feature substance according to the invention for a security feature, for example in a banknote, is shown in FIG. 11 . 11 shows the carrier film 28 , on one side of which the metallization 29 is applied. The other side of the carrier film 28 carries the further layer 30 made of the electrically conductive polymer.
    The further layer 30 is applied to the carrier film 28 by customary technological processes, for example by calendering. A composite film is thus formed, to which the metallization 29 is then applied, for example by vapor deposition.
    It is of course also possible to apply the further layer 30 made of the electrically conductive polymer to the metallization 29 after the vapor deposition of the carrier film 28 . In such a film structure, the additional layer 30 has a certain protective effect for the metallization 29 .

    Beispiel 6:Example 6:

    Fig. 12 zeigt eine andere bevorzugte Ausführung des Fölienaufbaus mit dem erfindungsgemäßen Merkmalsstoff. Dargestellt ist die Trägerfolie 28 mit der Metallisierung 29. Zwischen der Trägerfolie 28 und der Metallisierung 29 befindet sich die weitere Schicht 30 PEDT/PSS als ein Haftvermittler zwischen der Trägerfolie 28 und der Metallisierung 29. Die Anordnung der weiteren Schicht 30 als ein Haltvermittler ist nicht auf eine Verbesserung der Haftung zwischen der Trägerfolie 28 und der Metallisierung 29 beschränkt. Die weitere Schicht 30 ist zwischen beliebigen anderen Folien oder Schichten zur Verbesserung der Haftung einsetzbar. Als Haftvermittler zwischen der Trägerfolie 28 und der Metallisierung 29 entsteht jedoch der Vorteil, daß die relativ spröde Metallisierung 29 auf der wesentlich elastischeren weiteren Schicht 30 erheblich höheren mechanischen Beanspruchungen widersteht als bei einer unmittelbaren Bedampfung der Trägerfolie 28. 12 shows another preferred embodiment of the film structure with the feature substance according to the invention. The carrier film 28 with the metallization 29 is shown . Between the carrier foil 28 and the metallization 29, the further layer 30 of PEDT / PSS is as a bonding agent between the support foil 28 and the metallization 29th The arrangement of the further layer 30 as a holding agent is not limited to an improvement in the adhesion between the carrier film 28 and the metallization 29 . The further layer 30 can be used between any other films or layers to improve the adhesion. As an adhesion promoter between the carrier film 28 and the metallization 29 , however, there is the advantage that the relatively brittle metallization 29 on the significantly more elastic layer 30 withstands significantly higher mechanical stresses than when the carrier film 28 is vaporized directly.

    Beispiel 7:Example 7:

    Fig. 13 zeigt einen Folienaufbau für ein Sicherheitsmerkmal mit dem erfindungsgemäßen Merkmalsstoff unter Verwendung einer Trägerfolie 28, auf die die Metallisierung 29 aufgebracht ist. Die Metallisierung 29 ist durch eine weitere Trägerfolie 28' abgedeckt. Das geschieht beispielsweise zum Schutz der Metallisierung 29, wenn diese bei einem Fensterfaden mit einer teilweisen Einbettung in die Papierbahn einer erhöhten Beanspruchung ausgesetzt ist. Erhöhte Beanspruchungen während des technologischen Prozesses der Papierherstellung sind ein weiterer Grund für den Einsatz einer weiteren Trägerfolie 28'. Mindestens eine der Trägerfolien 28; 28' ist mit der weiteren Schicht 30 aus dem elektrisch leitenden Polymer versehen. 13 shows a film structure for a security feature with the feature substance according to the invention using a carrier film 28 to which the metallization 29 is applied. The metallization 29 is covered by a further carrier film 28 ' . This is done, for example, to protect the metallization 29 when it is exposed to increased stress in a window thread with a partial embedding in the paper web. Increased stresses during the technological process of paper production are a further reason for the use of a further carrier film 28 ' . At least one of the carrier films 28; 28 ' is provided with the further layer 30 made of the electrically conductive polymer.

    Beispiel 8:Example 8:

    In der Fig. 13 tragen beide Trägerfolien 28; 28' die weitere Schicht 30, während in der Fig. 14 eine Ausführung dargestellt ist, in der nur eine der Trägerfolien 28 die weitere Schicht 30 aus dem elektrisch leitenden Polymer trägt.
    Die Erfindung ist nicht darauf beschränkt, daß der erfindungsgemäße Merkmalsstoff als eine weitere Schicht 30 in einem Folienaufbau Verwendung findet. Der erfindungsgemäße Merkmalsstoff ist in beliebiger Konfiguration als ein Sicherheitsmerkmal in die Papierbahn einbringbar.     13 , both carrier films 28; 28 ' the further layer 30 , while FIG. 14 shows an embodiment in which only one of the carrier films 28 carries the further layer 30 made of the electrically conductive polymer.
    The invention is not restricted to the feature substance according to the invention being used as a further layer 30 in a film structure. The feature substance according to the invention can be introduced into the paper web as a security feature in any configuration.

    Beispiel 9:Example 9:

    Es dient der Verbesserung der Fälschungssicherheit, neben dem Merkmal der elektrischen Leitfähigkeit weitere Sicherheitsmerkmale vorzusehen und diese in geeigneter Weise zu kombinieren. So sind beispielsweise neben der elektrischen Leitfähigkeit des Polymers sowohl humanvisuell erkennbare Merkmalspigmente als auch solche vorgesehen, die nur mit geeigneten Prüfvorrichtungen, wie mit speziellen Lichtquellen und optischen Sensoren, erkennbar sind. Darüber hinaus erstreckt sich die Erfindung auch auf die Kombination der elektrischen Leitfähigkeit mit solchen Zuschlagstoffen, die magnetische Eigenschaften besitzen. Besonders vorteilhaft im Sinne der Erfindung ist eine Kombination der elektrischen Leitfähigkeit mit optischen und magnetischen Merkmalsstoffen. Als eine bevorzugte Anwendung sei erwähnt, die Zuschlagstoffe mit magnetischen Eigenschaften durch das Hinzufügen von humanvisuell erkennbaren Merkmalspigmenten zu verbergen. Somit bleibt es einem potentiellen. Fälscher ungewiß, ob ein magnetisch wirksamer Stoff vorhanden ist, insbesondere da die verwendeten Mengen gering und die magnetischen Auswirkungen nicht ohne weiteres erfaßbar sind.It serves to improve counterfeit security, in addition to the feature of electrical Conductivity to provide additional security features and these in a suitable manner combine. For example, in addition to the electrical conductivity of the polymer, both human-visually recognizable feature pigments as well as those provided only with suitable Test devices, such as with special light sources and optical sensors, are recognizable. In addition, the invention extends to the combination of electrical Conductivity with additives that have magnetic properties. Especially A combination of the electrical conductivity with is advantageous in the sense of the invention optical and magnetic feature substances. As a preferred application, the Additives with magnetic properties by adding human-visual hide recognizable feature pigments. So it remains a potential. counterfeiter uncertain whether a magnetically active substance is present, especially since those used Amounts small and the magnetic effects are not easily detectable.

    Neben einem bloßen Vorhandensein von optisch wirksamen Zuschlagstoffen in dem PEDT/PSS erstreckt sich die Erfindung auch darauf, daß die optisch wirksamen Zuschlagstoffe derart in dem elektrisch leitenden Polymer angeordnet sind, daß eine optische Kodierung entsteht, beispielsweise ein mit Prüfvorrichtungen auswertbares Farbmuster. Das gleiche betrifft die magnetisch wirksamen Zuschlagstoffe, durch deren erfindungsgemäße Anordnung eine magnetische Kodierung entsteht, beispielsweise in der Form eines magnetischen Strichkodes.In addition to the mere presence of optically effective additives in the PEDT / PSS The invention also extends to the fact that the optically active additives in the electrically conductive polymer are arranged so that an optical coding is produced, for example a color sample that can be evaluated with test devices. The same applies to the magnetically active additives, by their arrangement according to the invention Magnetic coding is created, for example in the form of a magnetic bar code.
