Abstract

The invention concerns a method for making secure sheets for bank note paper, consisting of a translucent support sheet and a masking coat applied on said sheet, with coat-free zones, in the form of letters, figures, signs, points and/or patterns and the like, capable of being clearly identified by transmission lighting. In said method, the support sheet is first printed with the letters, figures, signs, points and/or patterns and the like, said printing being produced with ink having high pigment content. The ink is then dried to obtain an embossed porous coat. Said coat, as well as the masking coat applied thereon or introduced therein, are eliminated by washing with a liquid. After it has dried, the support sheet can optionally be cut out into the required dimensions. The invention also concerns a secure sheet obtained by said method.

Description

Sicherheitsfolien für Wertpapiere und Verfahren zu ihrer Herstellung Security films for securities and processes for their manufacture
Die Erfindung betrifft eine Sicherheitsfolie zur Einlagerung oder Aufbringung in oder auf Wertpapiere, bestehend aus einer transluzenten Trägerfolie und einer darauf aufgebrachten Abdeckschicht, die beschichtungsfreie Bereiche in Form von Buchstaben, Zahlen, Zeichen, Punkten und/ oder Mustern aufweist, die insbesondere im Durchlicht klar zu erkennen sind. Die Erfindung betrifft auch ein Verfahren zur Herstellung derartiger Folien.The invention relates to a security film for storage or application in or on securities, consisting of a translucent carrier film and a covering layer applied thereon, which has coating-free areas in the form of letters, numbers, characters, dots and / or patterns, which are particularly clear in transmitted light are recognizable. The invention also relates to a method for producing such films.
Sicherheitsfolien in Form von Fäden oder Bändern, die in Wertpapiere, wie Banknoten, Schecks, Identitäts-, Kreditkarten und dergleichen eingebettet werden, sind bekannt. Zur Erhöhung der Sicherheit und als Fälschungsschutz sind derartige Fäden häufig mit einer sogenannten Negativschrift versehen. Diese Schrift wird durch metallfreie Bereiche in einer ansonsten vollflächigen metallischen Beschichtung des die Fäden bildenden, lichtdurchlässigen Trägermaterials gebildet. Hält man ein Wertpapier, das einen derartigen Faden enthält, gegen das Licht, so erscheint der Faden an sich wegen der opaken metallischen Beschichtung dunkel. Die metallfreien Bereiche heben sich vor diesem dunklen Hintergrund hell und kontrastierend ab. Bilden diese metallfreien Bereiche einen Schriftzug, so bildet das Wiedererkennen eines solchen Schriftzugs einen hervorragenden Schutz gegen Fälschungen.Security films in the form of threads or tapes which are embedded in securities such as banknotes, checks, identity cards, credit cards and the like are known. To increase security and to prevent counterfeiting, such threads are often provided with a so-called negative writing. This writing is formed by metal-free areas in an otherwise full-surface metallic coating of the translucent carrier material forming the threads. If you hold a security that contains such a thread against the light, the thread itself appears dark because of the opaque metallic coating. The metal-free areas stand out against this dark background in a bright and contrasting way. If these metal-free areas form a lettering, the recognition of such lettering forms an excellent protection against counterfeiting.
Zur Herstellung derartiger Sicherheitsfolien und Sicherheitsfäden sind eine Reihe von Verfahren bekannt. In der EP 0330 733 sind mehrere Verfahren zu ihrer Herstellung beschrieben. Neben den konventionellen Ätzverfahren wird auch auf ein Herstellverfahren verwiesen, bei dem auf die metallbeschichtete Seite der Folie eine Druckfarbe aufgedruckt wird, die thermoplastische Eigenschaften besitzt und bei höheren Temperaturen erweicht und klebrig wird. Kaschiert man eine so vorbehandelte Folie unter Anwendung von Wärme und Druck gegen eine zweite unbehandelte Folienbahn, so haften die beiden Folien im Bereich der aufgedruckten Schriftzeichen oder Mu- ster aneinander. Beim Trennen der beiden Folien werden dann aus der Me- tallbeschichtung die den Zeichen oder Mustern entsprechenden Bereiche herausgelöst.A number of methods are known for producing such security films and security threads. Several processes for their production are described in EP 0330 733. In addition to the conventional etching process, reference is also made to a production process in which a printing ink is printed on the metal-coated side of the film, which has thermoplastic properties and softens and becomes sticky at higher temperatures. If a film pretreated in this way is laminated against a second untreated film web using heat and pressure, the two films adhere in the area of the printed characters or mu each other. When the two foils are separated, the areas corresponding to the characters or patterns are then removed from the metal coating.
Zur Herstellung von Verpackungsmaterial ist es aus der DE-OS 36 10 379 bekannt, auf die Folien zunächst ein Druckbild aufzudrucken, wie es später in der Metallbeschichtung als Negativbild erscheinen soll und erst in einem zweiten Verfahrensschritt die Metallbeschichtung aufzubringen. Für die Aufbringung des Druckbildes werden dabei Druckfarben oder Lacke ver- wendet, die zur Metallbeschichtung eine geringe Haftung aufweisen. Die Metallbeschichtung wird dann mechanisch durch Einwirkung eines Luftoder Flüssigkeitsstrahls oder auch über eine mechanische Schabeinrichtung entfernt. Alternativ wird auch vorgeschlagen, die Druckfarben unter der Metallbeschichtung chemisch anzulösen und im Lösungsbad eine Ultraschall- quelle vorzusehen. Auch die Verwendung von besonders spröden Druckfarben ist bekannt. Zur Herstellung der Negativschrift wird bei Verwendung dieser Farbe die Folie nach dem Bedrucken mit Metall bedampft und nach der Bedampfung über eine scharfe Kante gezogen. Dabei wird der spröde Lack brechen und abplatzen, wobei die darüberliegende Metallschicht mit- genommen und ebenfalls entfernt wird. Alternativ kann auch hier ein Ultraschallbad zur Entfernung der Metallschicht über dem Lackaufdruck eingesetzt werden.For the production of packaging material, it is known from DE-OS 36 10 379 to first print a printed image on the foils, as it will later appear as a negative image in the metal coating, and to apply the metal coating only in a second process step. Printing inks or varnishes with low adhesion to the metal coating are used to apply the printed image. The metal coating is then removed mechanically by the action of an air or liquid jet or also by means of a mechanical scraping device. Alternatively, it is also proposed to chemically dissolve the printing inks under the metal coating and to provide an ultrasound source in the solution bath. The use of particularly brittle printing inks is also known. To produce the negative writing, the film is steamed with metal after printing and drawn over a sharp edge after steaming. The brittle paint will break and flake off, taking the overlying metal layer with it and also removing it. Alternatively, an ultrasonic bath can also be used to remove the metal layer above the varnish.
Beim Einsatz von Sicherheitsfäden in Wertpapieren wird insbesondere auf konturenscharfe Zeichen Wert gelegt, d. h. die Ränder der Negativdarstellung sollen glatt und linienför ig begrenzt sein. Die bekannten Verfahren sind in dieser Hinsicht verbesserungsbedürftig. Die bekannten Verfahren sind überdies zeitaufwendig und belasten zum Teil die Umwelt. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem Negativdarstellungen in metallbeschichteten Folien erzeugt werden können, die sich durch eine hohe Konturenschärfe auszeichnen. Darüber hinaus soll das Verfahren einfach und umweltverträglich sein.When using security threads in securities, particular emphasis is placed on sharply defined characters, ie the edges of the negative display should be smooth and line-bounded. The known methods are in need of improvement in this regard. The known methods are also time-consuming and sometimes pollute the environment. The invention is based on the object of specifying a method with which negative representations can be produced in metal-coated foils which are distinguished by a high degree of contour sharpness. In addition, the process should be simple and environmentally friendly.
Erfindungsgemäß wird diese Aufgabe durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen des Verfahrens sind Gegenstand der Unteransprüche.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1. Advantageous developments of the method are the subject of the dependent claims.
Wesentlich für die Erfindung ist die Erkenntnis, daß eine in einem Druckverfahren verdruckte Farbe mit einem hohen Pigmentanteil nach dem Trocknen auf der Druckunterlage einen erhabenen Farbauftrag bildet, der eine poröse, porige Struktur mit großer Oberfläche besitzt. Eine auf einen solchen Farbauftrag aufgebrachte Abdeckschicht geringer Dicke führt zu keiner durchge- henden, flächendeckenden Beschichtung, sondern deckt den getrockneten Farbkörper wegen dessen großer Oberfläche und porösen Struktur nur teilweise ab, so daß der Farbkörper zumindest teilweise von außen für Lösungsmittel leicht zugänglich bleibt. Verwendet man für die Farbe ein lösliches Bindemittel, so kann der Farbauftrag und mit dem Farbauftrag auch die darauf abgelagerte Abdeckschicht durch Beaufschlagung mit einem geeigneten Lösungsmittel ausgewaschen werden. Das Auswaschen kann durch mechanische Mittel unterstützt werden. Als Abdeckschicht können beliebige opake Beschichtungen verwendet werden. Vorzugsweise werden jedoch Me- tallbeschichtungen, wie z.B. Aluminium-, Eisen-, Cobalt- oder Nickelbe- Schichtungen eingesetzt. Ein solches Verfahren führt zu überraschend scharfen und definierten Kantenkonturen und eignet sich daher besonders zur Herstellung einer Negativschrift für Sicherheitsfäden, die in Wertpapiere, wie Banknoten eingelagert werden. Diese Konturenschärfe ermöglicht auch die Herstellung von gerasterten Halbtonbildern. Auf beschichteten Sicherheitsfolien können somit erstmals Halbtonbilder, wie Portraits in der Abdeckschicht ausgebildet werden. Bettet man diese Folien zwischen zwei Lagen eines Sicherheitspapiers ein, entsteht ein wasserzeichenähnlicher Effekt, da die Portraits im Auflicht nicht oder nur schwach, im Durchlicht aber sehr gut und kontrastreich zu erkennen sind. Möglich sind Negativ- aber auch Positivdarstellungen.It is essential for the invention to recognize that a color printed in a printing process with a high pigment content forms a raised color application after drying on the printing substrate, which has a porous, porous structure with a large surface area. A covering layer of small thickness applied to such a paint application does not lead to a continuous, surface-covering coating, but rather only partially covers the dried paint body because of its large surface area and porous structure, so that the paint body remains easily accessible from the outside, at least in part, for solvents. If a soluble binder is used for the paint, the paint application and, with the paint application, the covering layer deposited thereon can be washed out by applying a suitable solvent. The washing out can be supported by mechanical means. Any opaque coatings can be used as a covering layer. However, metal coatings, such as aluminum, iron, cobalt or nickel coatings, are preferably used. Such a method leads to surprisingly sharp and defined edge contours and is therefore particularly suitable for producing negative writing for security threads which are stored in securities such as bank notes. This sharpness of contours also enables the production of halftone images. Halftone images, such as portraits, can thus be formed in the cover layer for the first time on coated security films. If these foils are embedded between two layers of security paper, a watermark-like effect is created, since the portraits are not or only weakly visible in reflected light, but can be recognized very well and in high contrast in transmitted light. Negative but also positive representations are possible.
Nachfolgend werden Ausführungsformen der Erfindung anhand der beige- fügten Zeichnungen beschrieben. Darin zeigen:Embodiments of the invention are described below with reference to the accompanying drawings. In it show:

Fig. 2 die gleiche Ansicht, jedoch nach dem Auswaschen.Fig. 2 shows the same view, but after washing out.
Zunächst wird eine lichtdurchlässige transparente Trägerfolie 10 bereitgestellt. Das bevorzugte Material ist Polyester; andere Kunststoffe, können ebenfalls verwendet werden, vorausgesetzt, sie sind lichtdurchlässig, haben eine ausreichende Festigkeit und eine Oberfläche, die sich bedrucken und mit einer Abdeckschicht, insbesondere Metall, beschichten läßt. Die Dicke der Folie beträgt etwa 6 bis 36 μm.First, a translucent transparent carrier film 10 is provided. The preferred material is polyester; other plastics can also be used, provided that they are translucent, have sufficient strength and have a surface that can be printed and coated with a cover layer, especially metal. The thickness of the film is approximately 6 to 36 μm.
Die Folie wird üblicherweise in Form endloser Bänder verwendet, da dasThe film is usually used in the form of endless tapes because that
Verfahren vorzugsweise kontinuierlich durchgeführt wird. Für den Fall, daß Sicherheitsfäden hergestellt werden sollen, werden die Bänder nach ihrer Fertigstellung entsprechend zugeschnitten. Die Folie wird in einem ersten Schritt mit Schriftzeichen, Symbolen oder Mustern bedruckt. Das Bedrucken kann mit einem gängigen Druckverfahren erfolgen, jedoch wird vorzugsweise ein Tiefdruckzylinder eingesetzt, da beim Tief drucken besonders klare Kantenkonturen und ein entsprechend hoher Farbauftrag erreicht werden können. Als Druckfarbe wird eine Farbe mit einem hohen Pigmentanteil verwendet. Der Pigmentanteil, bezogen auf das Trockengewicht der Farbe, sollte zur Erzeugung der porösen Struktur etwa zwischen 10 % und 80 %, bevorzugt bei etwa 60 % liegen.Process is preferably carried out continuously. In the event that security threads are to be produced, the tapes are cut accordingly after their completion. In a first step, the film is printed with characters, symbols or patterns. The printing can be done with a common printing process, but preferably an intaglio cylinder is used, since in gravure printing particularly clear edge contours and a correspondingly high ink application can be achieved. A color with a high pigment content is used as printing ink. The proportion of pigment, based on the dry weight of the paint, should be approximately between 10% and 80%, preferably approximately 60%, in order to produce the porous structure.
Als Pigmente werden vorzugsweise natürliche Rohstoffe gewählt, vorzugsweise Kreide, aber auch Bentonit, Aerosil und Titandioxid. Geeignete Pigmente werden von den Martinswerken unter dem Namen Pergopak, von Rohm & Haas unter dem Namen Rhopaque und von der Degussa unter dem Namen Aerosil angeboten. Darüber hinaus können auch organische Partikel, wie ungekochte Stärke verwendet werden. Durch den hohen Pigmentanteil bildet die Farbe nach dem Trocknen eine porige, poröse Struktur mit einer unregelmäßigen, vergleichsweise hohen Oberfläche.Natural raw materials are preferably selected as pigments, preferably chalk, but also bentonite, aerosil and titanium dioxide. Suitable pigments are available from Martinswerke under the name Pergopak, from Rohm & Haas under the name Rhopaque and from Degussa under the name Aerosil. Organic particles such as uncooked starch can also be used. Due to the high pigment content, the paint forms a porous, porous structure with an irregular, comparatively high surface after drying.
Vorzugsweise werden für die Druckfarbe wasserlösliche Bindemittel ver- wendet, so d.aß der Farbauftrag mit Wasser wieder gelöst und abgewaschen werden kann. Als derartiges Bindemittel eignet sich beispielsweise gekochte bzw. gelöste Stärke, Polyvinylalkohol (PVA) oder Carboximethylcellulose (CMC).Water-soluble binders are preferably used for the printing ink, so that the ink application can be dissolved again and washed off with water. Boiled or dissolved starch, polyvinyl alcohol (PVA) or carboxymethyl cellulose (CMC), for example, are suitable as such binders.
In einem Druckwerk werden diejenigen Bereiche der Trägerfolie bedruckt, die später die metallfreien Bereiche der Folie bilden sollen und die, wegen der Lichtdurchlässigkeit der Trägerfolie, im Durchlicht hell und kontrastierend gegen die Umgebung der Beschichtung erkennbar sein sollen. Nach dem Trocknen hat der Farbauftrag eine porige, poröse Struktur und ein erhabenes Profil. Ein Querschnitt durch einen solchen Farbauftrag 30 zeigt Fig. 1.In a printing unit, those areas of the carrier film are printed which are later to form the metal-free areas of the film and which, owing to the translucency of the carrier film, should be recognizable in transmitted light in a light and contrasting manner with the surroundings of the coating. To After drying, the paint application has a porous, porous structure and a raised profile. A cross section through such a paint application 30 is shown in FIG. 1.
Nach dem Trocknen des Farbauftrages wird eine geeignete, bevorzugt opake Abdeckschicht aufgebracht, die in den Bereichen des Farbauftrages wieder entfernt werden kann. Hierzu wird die Folie nach dem Trocknen im Vakuum z.B. mit einer ca. 0,1 μm Schicht aus Aluminium bedampft. Statt Aluminium kann auch Nickel oder ein anderes geeignetes Metall eingesetzt wer- den. Statt dem Metall kann auch ein anderes opakes Material eingesetzt werden, vorausgesetzt es kann durch ein dem Aufdampfen ähnliches Verfahren aufgebracht werden und hat bei Schichtstärken von etwa 0,1 μm eine optische Dichte oberhalb von 1,8, so daß die Schicht im wesentlichen undurchsichtig ist. Die Schichtstärken können auch je nach Anwendung in ei- nem Bereich von 0,01 bis 1 μm variieren.After the paint application has dried, a suitable, preferably opaque cover layer is applied, which can be removed again in the areas of the paint application. For this purpose, the film is dried in a vacuum, e.g. evaporated with an approx. 0.1 μm layer of aluminum. Instead of aluminum, nickel or another suitable metal can also be used. Instead of the metal, another opaque material can also be used, provided that it can be applied by a method similar to evaporation and has an optical density above 1.8 with layer thicknesses of about 0.1 μm, so that the layer is essentially opaque . Depending on the application, the layer thicknesses can also vary in a range from 0.01 to 1 μm.
Die in den Fig. 1 und 2 mit 20 gekennzeichnete metallische Beschichtung lagert sich auch auf dem Farbauftrag 30 ab; allerdings bildet sie dort infolge der porösen Struktur und der damit verbundenen hohen Oberfläche des Farbauftrags keine zusammenhängende Schicht. Denn bei der Beschichtung des Farbauftrags 30 lagern sich die Beschichtungspartikel, hier die Metallpartikel, die auf edampft werden, in den Poren des Farbauftrags 30 ab. Damit dringen die Beschichtungspartikel sozusagen in den Farbauftrag 30 ein, so daß an der Oberfläche keine zusammenhängende Schicht erzeugt wird. Der poröse Oberflächenbereich, in den die Metallpartikel eingedrungen sind und der demzufolge keine zusammenhängende Metallschicht aufweist, ist in Fig. 1 schraffiert dargestellt und mit 40 bezeichnet. Die mit der hochpigmentierten Druckfarbe bedruckte Trägerfolie wird anschließend einem Waschvorgang unterzogen. Bei diesem Waschvorgang kann die Waschflüssigkeit die nicht zusammenhängende Beschichtung leicht durchdringen. Es gelingt somit leicht, die Druckzeichen zusammen mit der nicht zusammenhängenden Metallschicht abzuwaschen.Vorzugsweise wird der Waschgang der Metallisierung nachgeschaltet. Die Wirkung der Waschflüssigkeit kann durch mechanische Mittel, wie Bürsten, Walzen oder Ultraschall unterstützt werden.The metallic coating marked 20 in FIGS. 1 and 2 is also deposited on the paint application 30; however, due to the porous structure and the associated high surface area of the paint application, it does not form a coherent layer there. Because when coating the paint application 30, the coating particles, here the metal particles that are vapor-deposited, are deposited in the pores of the paint application 30. The coating particles thus penetrate the paint application 30, so to speak, so that no coherent layer is produced on the surface. The porous surface area into which the metal particles have penetrated and which consequently does not have a coherent metal layer is shown hatched in FIG. 1 and designated by 40. The carrier film printed with the highly pigmented printing ink is then subjected to a washing process. During this washing process, the washing liquid can easily penetrate the non-coherent coating. It is therefore easy to wash off the printed characters together with the non-contiguous metal layer. The washing step is preferably carried out after the metallization. The action of the washing liquid can be supported by mechanical means, such as brushes, rollers or ultrasound.
Bei Verwendung eines wasserlöslichen Bindemittels für die Farbe kann Wasser als Waschflüssigkeit eingesetzt werden. Bei Verwendung anderer Bindemittel muß ein entsprechendes organisches Lösungsmittel verwendet werden. Durch die Behandlung der Folie mit der Waschflüssigkeit, eventuell unterstützt durch mechanische Mittel, wird die Farbe 30 zusammen mit dem in den Farbauftrag eingedrungenen Metallauftrag 40 schonend und restlos von der Trägerfolie 10 entfernt.When using a water-soluble binder for the paint, water can be used as the washing liquid. If other binders are used, an appropriate organic solvent must be used. By treating the film with the washing liquid, possibly supported by mechanical means, the paint 30 is gently and completely removed from the carrier film 10 together with the metal application 40 that has penetrated the paint application.
Nach dem Auswaschen der Farbe wird die Folienbahn getrocknet und zugeschnitten, um beispielsweise Sicherheitsfäden zu bilden, die dann in Papier für Banknoten eingelagert werden können. Die Folienbahn kann allerdings auch als Transferfolie ausgebildet werden, mit deren Hilfe Sicherheitselemente beliebiger Form auf Sicherheitsdokumente oder beliebige andere zu sichernde Produkte übertragen werden können. Auch der Einsatz als Etikettenmaterial ist möglich.After the color has been washed out, the film web is dried and cut to form, for example, security threads which can then be stored in paper for banknotes. However, the film web can also be designed as a transfer film, with the aid of which security elements of any shape can be transferred to security documents or any other products to be secured. It can also be used as label material.
Ebenso ist es möglich, das beschriebene Verfahren auf Folien anzuwenden, die zuvor mit einer beliebigen anderen Effektschicht, wie z.B. einem Druckmuster, einer beugungsoptisch wirksamen Schicht (Flüssigkristallpigmente, Interferenzschichten, Hologramme etc.) versehen wurde. Wie in Fig. 2 schematisch dargestellt, ergibt das beschriebene Verfahren besonders scharfe und gut definierte Kantenstrukturen der Negativdarstellungen. Die Konturenschärfe der aufgedruckten Zeichensymbole und/ oder -muster ist daher besonders gut und Fälschungen, die diese Qualität nicht aufweisen, sind leicht zu erkennen.It is also possible to apply the described method to foils which have previously been provided with any other effect layer, such as, for example, a printed pattern, a diffraction-optically effective layer (liquid crystal pigments, interference layers, holograms, etc.). As shown schematically in FIG. 2, the described method results in particularly sharp and well-defined edge structures of the negative representations. The sharpness of the contours of the printed symbols and / or patterns is therefore particularly good and forgeries that do not have this quality are easy to identify.
Wie beschrieben, liegt der Vorzug des erfinderischen Verfahrens auch in seiner Umweltverträglichkeit. Es brauchen keine schädlichen Chemikalien eingesetzt zu werden. Bei Verwendung wasserlöslicher Farben können die aus- gewaschenen Pigmente mit bekannten Verfahren aus dem Abwasser entfernt werden. Auch hat sich gezeigt, daß das erfinderische Verfahren verglichen mit anderen Verfahren weniger zeitaufwendig ist. As described, the advantage of the inventive method also lies in its environmental compatibility. No harmful chemicals need to be used. If water-soluble paints are used, the washed-out pigments can be removed from the waste water using known methods. It has also been shown that the inventive method is less time-consuming compared to other methods.
