Description

Die Erfindung betrifft ein Sicherheitselement, insbesondere ein Sicherheitsetikett, das einen Manipulationsnachweis erlaubt.The invention relates to a security element, in particular a security label, which allows a proof of tampering.

Im Besonderen betrifft die vorliegende Erfindung Sicherheitsetiketten, die eine im unversehrten Zustand nicht sichtbare optisch aktive Struktur aufweisen, die erst nach einem Manipulationsversuch erkennbar wird.In particular, the present invention relates to security labels which have an optically active structure which is invisible in the intact state and which becomes recognizable only after a manipulation attempt.

Aus WO 01/93231 ist ein Sicherheitsetikett, das zwei Mikrostrukturen aufweist, von denen eine, eine auch in nicht manipuliertem Zustand erkennbare, diffraktive Struktur und die andere eine, den Release kontrollierende, Struktur ist. Bei einem Manipulationsversuch werden zumindest Teile einer reflektierenden Schicht abgelöst, wodurch eine neue visuell erkennbare Information sichtbar wird.Out WO 01/93231 is a security label that has two microstructures, one of which is a diffractive structure, also recognizable in an unmanipulated state, and the other a release-controlling structure. In a manipulation attempt, at least parts of a reflective layer are peeled off, whereby a new visually recognizable information becomes visible.

FR-A-2 867 590 offenbart ein Verfahren zum Schützen eines Objekts, wobei zumindest auf einen Teil der Oberfläche eine Schutzfolie aufgebracht wird, die aus mehreren Schichten besteht. Die erste Schicht besteht aus der das fertige Muster bildenden Quelle, wobei das Muster in diesem Zustand nicht lesbar ist. Auf diese Schicht wird anschließend eine sogenannte Decodierungsschicht aufgebracht, die transparent erscheint und das Muster erkennbar macht. FR-A-2 867 590 discloses a method for protecting an object, wherein a protective film consisting of several layers is applied to at least part of the surface. The first layer consists of the source forming the finished pattern, the pattern being unreadable in this state. Subsequently, a so-called decoding layer is applied to this layer, which appears transparent and makes the pattern recognizable.

Bei einem Manipulationsversuch durch Ablösen der Schutzschicht wird die Decodierungsschicht von der die Musterquelle bildenden Schicht abgelöst, das Muster ist nicht mehr erkennbar.In a manipulation attempt by detachment of the protective layer, the decoding layer is detached from the layer forming the pattern source, the pattern is no longer recognizable.

EP-A-0 401 466 offenbart einen Schichtverbund mit einer zwischen zwei Lackschichten eingebetteten Beugungsstruktur, die über der ersten Lackschicht eine optisch klare Stabilisierungsschicht aufweist. Die Stabilisierungsschicht dient dazu, die Wärme bei Aufkleben des Schichtverbundes gleichmäßig zu verteilen. EP-A-0 401 466 discloses a composite layer with a diffraction structure embedded between two layers of lacquer which has an optically clear stabilizing layer over the first lacquer layer. The stabilization layer serves to evenly distribute the heat when the layer composite is adhered.

Aus dem Schichtverbund können Marken oder Etiketten gestanzt werden, die dann zur Sicherung auf ein Objekt aufgebracht werden.Stamps or labels can be punched out of the laminate, which are then applied to an object for securing purposes.

WO 03/066344 A beschreibt eine Sicherheitsvorrichtung, die eine erste Schicht und eine zweite Schicht beinhaltet. Die erste Schicht weist verborgene Merkmale auf, die zweite Schicht, weist decodierende optische Elemente auf und so ausgeführt ist, dass sie auf der ersten Schicht von einer Position zu einer anderen bewegt werden kann, wobei nur in einer der Positionen die verborgenen Merkmale erkennbar werden. Transferanwendungen sind ebenfalls beschrieben. WO 03/066344 A describes a security device that includes a first layer and a second layer. The first layer has hidden features, the second layer has decoding optical elements and is adapted to be moved from one position to another on the first layer, the hidden features becoming recognizable only in one of the positions. Transfer applications are also described.

Die verborgenen Merkmale werden also nur in bestimmten Positionen der zweiten Schicht sichtbarThe hidden features thus become visible only in certain positions of the second layer

Aufgabe der vorliegenden Erfindung war es ein Sicherheitselement, insbesondere ein Sicherheitsetikett bereitzustellen, das einen Manipulationsnachweis erlaubt, wobei das Sicherheitsmerkmal erst bei Manipulation erkennbar ist und in nicht manipuliertem Zustand nicht erkennbar ist.The object of the present invention was to provide a security element, in particular a security label, which permits a proof of tampering, wherein the security feature is recognizable only during manipulation and can not be recognized in a non-manipulated state.

Ferner soll das Sicherheitselement auf beiden Oberflächen in manipuliertem Zustand eine glatte, nicht klebrige Oberfläche aufweisen.Furthermore, the security element should have a smooth, non-sticky surface on both surfaces in a manipulated state.

Gegenstand der vorliegenden Erfindung ist daher ein Sicherheitselement, das folgende Schichten aufweist:

  • a) ein Trägersubstrat
  • b) eine erste Lackschicht, die eine beugungsoptisch aktive Struktur, wie ein Hologramm, ein Oberflächenrelief, eine Beugungsstruktur, ein Beugungsgitter oder ein Kinegramm aufweist
  • c) eine zweite Lackschicht
  • e) eine Klebebeschichtung,
dadurch gekennzeichnet, dass bei einem Manipulationsversuch die erste Lackschicht b) von der zweiten Lackschicht c) getrennt wird, und die in die erste Lackschicht b) eingebrachte optisch aktive Struktur sowohl in der ersten abgezogenen als auch in der zweiten auf dem zu sichernden Objekt verbleibenden Lackschicht als Negativ erkennbar wird.The subject matter of the present invention is therefore a security element which has the following layers:
  • a) a carrier substrate
  • b) a first resist layer having a diffractive optically active structure, such as a hologram, a surface relief, a diffraction structure, a diffraction grating or a kinegram
  • c) a second lacquer layer
  • e) an adhesive coating,
characterized in that in a manipulation attempt, the first resist layer b) is separated from the second resist layer c), and in the first resist layer b) introduced optically active structure in both the first stripped and in the second remaining on the object to be protected lacquer layer recognizable as a negative.

Gegebenenfalls kann zwischen den Schichten a) und b) eine Haftvermittlerschicht situiert sein.If appropriate, an adhesion promoter layer can be situated between the layers a) and b).

Unter optisch aktiver Struktur werden hier insbesondere beugungsoptisch aktive Strukturen, wie Hologramme, Oberflächenreliefs, Beugungsstrukturen, Beugungsgitter, Kinegramme und dergleichen verstanden.Optically active structures are understood here to be, in particular, diffraction-optically active structures, such as holograms, surface reliefs, diffraction structures, diffraction gratings, kinegrams and the like.

Unter einer reflektierenden Schicht wird hier insbesondere eine metallische Schicht oder eine metallisch erscheinende Schicht verstanden.A reflective layer is understood to mean in particular a metallic layer or a metallic appearing layer.

Unter einer Schicht mit optischen Merkmalen wird hier insbesondere eine farbige Schicht oder eine Schicht mit lumineszierenden, insbesondere fluoreszierenden oder phosphoreszierenden Eigenschaften verstanden.A layer with optical features is understood here in particular to be a colored layer or a layer having luminescent, in particular fluorescent or phosphorescent properties.

Die optischen Eigenschaften der Schicht lassen sich aber auch durch sichtbare Farbstoffe bzw. Pigmente, lumineszierende Farbstoffe bzw. Pigmente, die im sichtbaren, im UV-Bereich oder im IR-Bereich fluoreszieren bzw. phosphoreszieren, Effektpigmente, wie Flüssigkristalle, Perlglanz, Bronzen und/oder Multilayer-Farbumschlagpigmente und wärmeempfindliche Farben bzw. Pigmente beeinflussen. Diese sind in allen möglichen Kombinationen einsetzbar. Zusätzlich können auch phosphoreszierende Pigmente allein oder in Kombination mit anderen Farbstoffen und/oder Pigmenten eingesetzt werden.However, the optical properties of the layer can also be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV region or in the IR region, effect pigments, such as liquid crystals, pearlescent, bronzes and / or multilayer color change pigments and heat-sensitive inks or pigments. These can be used in all possible combinations. In addition, phosphorescent pigments can also be used alone or in combination with other dyes and / or pigments.

Als Trägersubstrate kommen beispielsweise Trägerfolien vorzugsweise flexible Kunststofffolien, beispielsweise aus PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC, Fluorpolymere, wie Teflon und dergleichen in Frage. Die Trägerfolien weisen vorzugsweise eine Dicke von 5 - 700 µm, bevorzugt 5 - 200 µm, besonders bevorzugt 5 - 100 µm auf.As carrier substrates, for example carrier films are preferably flexible plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , Fluoropolymers such as Teflon and the like in question. The carrier films preferably have a thickness of 5 to 700 μm, preferably 5 to 200 μm, particularly preferably 5 to 100 μm.

Ferner können auch, coextrudierte oder chemisch oder physikalisch vorbehandelte Kunststofffolien, beispielsweise acrylatbeschichtete Kunststofffolien als Trägersubstrat verwendet werden.Furthermore, coextruded or chemically or physically pretreated plastic films, for example acrylate-coated plastic films, can also be used as the carrier substrate.

Ferner können als Trägersubstrat auch Metallfolien, beispielsweise Al-, Cu-, Sn-, Ni-, Fe- oder Edelstahlfolien mit einer Dicke von 5 - 200 µm, vorzugsweise 10 bis 80 µm, besonders bevorzugt 20 - 50 µm dienen. Die Folien können auch oberflächenbehandelt, beschichtet oder kaschiert beispielsweise mit Kunststoffen oder lackiert sein.Furthermore, metal foils, for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 μm, preferably 10 to 80 μm, particularly preferably 20-50 μm, may also serve as the carrier substrate. The films can also be surface-treated, coated or laminated, for example, with plastics or painted.

Ferner können als Trägersubstrate auch Papier oder Verbunde mit Papier, beispielsweise Verbunde mit Kunststoffen mit einem Flächengewicht von 20 - 500 g/m2, vorzugsweise 40 - 200 g/m2. verwendet werden.Further, as carrier substrates also paper or composites with paper, for example, composites with plastics with a grammage 20-500 g / m 2, preferably 40-200 g / m 2. be used.

Das Trägersubstrat kann gegebenenfalls mit einem Haftvermittler beschichtet sein.If appropriate, the carrier substrate may be coated with a bonding agent.

Auf das Trägersubstrat wird eine Lackschicht b) aufgebracht.On the carrier substrate, a resist layer b) is applied.

Diese Lackschicht kann eine strahlungshärtbare Lackschicht oder eine thermoplastische Lackschicht sein.This lacquer layer may be a radiation-curable lacquer layer or a thermoplastic lacquer layer.

Der strahlungshärtbare Lack kann beispielsweise ein strahlungshärtbares Lacksystem auf Basis eines Polyester-, eines Epoxy- oder Polyurethansystems das zwei oder mehr verschiedene, dem Fachmann geläufige Photoinitiatoren enthält, die bei unterschiedlichen Wellenlängen eine Härtung des Lacksystems in unterschiedlichem Ausmaß initiieren können. So kann beispielsweise ein Photoinitiator bei einer Wellenlänge von 200 bis 400 nm aktivierbar sein, der zweite Photoinitiator dann bei einer Wellenlänge von 370 bis 600 nm aktivierbar. Zwischen den Aktivierungswellenlängen der beiden Photoinitiatoren sollte genügend Differenz eingehalten werden, damit nicht eine zu starke Anregung des zweiten Photoinitiators erfolgt, während der erste Photoinitiator aktiviert wird. Der Bereich, in dem der zweite Photoinitiator angeregt wird, sollte im Transmissionswellenlängenbereich des verwendeten Trägersubstrats liegen. Für die Haupthärtung (Aktivierung des zweiten Photoinitiators) kann auch Elektronenstrahlung verwendet werden.The radiation-curable lacquer may contain, for example, a radiation-curable lacquer system based on a polyester, an epoxy or polyurethane system which contains two or more different photoinitiators familiar to the person skilled in the art, which can initiate curing of the lacquer system to varying degrees at different wavelengths. Thus, for example, a photoinitiator can be activated at a wavelength of 200 to 400 nm, the second photoinitiator then activatable at a wavelength of 370 to 600 nm. Sufficient difference should be maintained between the activation wavelengths of the two photoinitiators to prevent over-excitation of the second photoinitiator while the first photoinitiator is activated. The region in which the second photoinitiator is excited should be in the transmission wavelength range of the carrier substrate used. For the main curing (activation of the second photoinitiator) also electron radiation can be used.

Als strahlungshärtbarer Lack kann auch ein wasserverdünnbarer Lack verwendet werden. Bevorzugt werden Lacksysteme auf Polyesterbasis.As a radiation-curable varnish, a water-thinnable varnish can also be used. Preference is given to polyester-based paint systems.

Die Abformung der Oberflächenstruktur, also der Diffraktions-, Beugungs- oder Reliefstruktur erfolgt beispielsweise bei kontrollierter Temperatur mittels einer Matrize oder unter Verwendung einer Prägeform in die strahlungshärtbare Lackschicht, die durch Aktivierung des ersten Photoinitiators bis zum Gelpunkt vorgehärtet wurde und zum Zeitpunkt der Abformung sich in diesem Stadium befindet.The impression of the surface structure, that is, the diffraction, diffraction or relief structure, for example, at controlled temperature by means of a die or using a stamping die in the radiation-curable lacquer layer, which was pre-cured by activation of the first photoinitiator to the gel point and at the time of molding in this stage is located.

Wird ein wasserverdünnbarer strahlungshärtbarer Lack verwendet kann gegebenenfalls eine Vortrocknung vorgeschaltet werden, beispielsweise durch IR-Strahler.If a water-dilutable radiation-curable lacquer is used, it is optionally possible to precede predrying, for example by means of IR radiators.

Der thermoplastische Lack, der anschließend stabilisiert wird, besteht aus einer Basis MMA oder Ethylcellulose oder Cycloolefincopolymer, wobei dem Basispolymer zur Einstellung der geforderten thermoplastischen Eigenschaften bzw. zur Einstellung der anschließenden Stabilisierbarkeit Modifikatoren zugesetzt werden.The thermoplastic varnish, which is subsequently stabilized, consists of a base MMA or ethylcellulose or cycloolefin copolymer, modifiers being added to the base polymer to adjust the required thermoplastic properties or to adjust the subsequent stabilizability.

In Abhängigkeit vom Basispolymer kommen als Modifikatoren beispielsweise Additive zur Einstellung der gewünschten Glastemperatur, des Bereichs in dem sich der Lack in thermoplastischem Zustand befindet, oder Modifikatoren zur Erreichung einer dauerhaften Aushärtung des Lacks in Frage.Depending on the base polymer, modifiers include, for example, additives for adjusting the desired glass transition temperature, the range in which the paint is in the thermoplastic state, or modifiers for achieving permanent curing of the paint.

Vorzugsweise werden die Komponenten in einem Lösungsmittel, beispielsweise in wässrigen Lösungsmitteln, Wasser, Alkoholen, Ethylacetat, Methylethylketon und dergleichen oder deren Mischungen gelöst.Preferably, the components are dissolved in a solvent, for example in aqueous solvents, water, alcohols, ethyl acetate, methyl ethyl ketone and the like or mixtures thereof.

Einem Lack auf Basis von MMA wird beispielsweise besonders vorteilhaft Nitrocellulose zur Erhöhung der Glastemperatur zugesetzt.For example, nitrocellulose for increasing the glass transition temperature is particularly advantageously added to a paint based on MMA.

Einem Lack auf der Basis von Cycloolefincopolymeren werden beispielsweise besonders vorteilhaft Polyethylenwachse zugesetzt.For example, it is particularly advantageous to add polyethylene waxes to a lacquer based on cycloolefin copolymers.

Einem Lack auf Basis von Ethylcellulose werden zur Einstellung der Härtbarkeit handelsübliche Crosslinker zugesetzt.Commercially available crosslinkers are added to an ethylcellulose-based lacquer to adjust the hardenability.

Die Konzentration des Basispolymeren im fertigen Lack beträgt in Abhängigkeit vom Basispolymeren, von den gewünschten Eigenschaften des Lacks und von der Art und Konzentration der Modifikatoren 4 - 50%.The concentration of the base polymer in the finished paint, depending on the base polymer, on the desired properties of the paint and on the type and concentration of the modifiers is 4-50%.

Die Strukturierung des thermoplastischen Lacks kann mittels eines konventionellen thermischen Prägeverfahrens erfolgen.The structuring of the thermoplastic paint can be carried out by means of a conventional thermal embossing process.

Die Schichtdicke des aufgebrachten Lacks kann je nach Anforderung an das Endprodukt und Dicke des Substrats variieren und beträgt im allgemeinen zwischen 0,5 und 50 µm, vorzugsweise zwischen 2 und 10 µm, besonders bevorzugt zwischen 2 und 5 µm.The layer thickness of the applied paint can vary depending on the requirements of the end product and thickness of the substrate and is generally between 0.5 and 50 .mu.m, preferably between 2 and 10 .mu.m, more preferably between 2 and 5 microns.

Auf diese Lackschicht b) wird nun eine weitere Lackschicht c) aufgebracht, die die gleiche oder eine andere Zusammensetzung wie die erste Lackschicht b) aufweisen kann.A further lacquer layer c), which may have the same or a different composition as the first lacquer layer b), is then applied to this lacquer layer b).

Gegebenenfalls kann diese Lackschicht c) eine zweite optisch aktive Struktur aufweisen.Optionally, this lacquer layer c) have a second optically active structure.

Dadurch wird die in die erste Lackschicht b) eingebrachte optisch aktive Struktur ausgelöscht, also unsichtbar.As a result, the optically active structure introduced into the first lacquer layer b) is extinguished, ie invisible.

Anschließend wird auf diese zweite Lackschicht c) ggf. eine reflektierende Schicht oder eine Schicht mit optischen Eigenschaften aufgebracht.Subsequently, a reflective layer or a layer with optical properties is applied to this second lacquer layer c) if necessary.

Diese reflektierende Schicht kann aus einem Metall, einer Metallverbindung, oder einer Legierung bestehen. Als Metallschicht sind Schichten aus Al, Cu, Fe, Ag, Au, Cr, Ni, Zn und dergleichen geeignet. Als Metallverbindungen sind beispielsweise Oxide oder Sulfide von Metallen, insbesondere TiO2, Cr-Oxide, ZnS, ITO, ATO, FTO, ZnO, Al2O3 oder Siliciumoxide geeignet. Geeignete Legierungen sind beispielsweise Cu-Al Legierungen, Cu-Zn Legierungen und dergleichen.This reflective layer may consist of a metal, a metal compound, or an alloy. As the metal layer, layers of Al, Cu, Fe, Ag, Au, Cr, Ni, Zn and the like are suitable. Examples of suitable metal compounds are oxides or sulfides of metals, in particular TiO 2 , Cr oxides, ZnS, ITO, ATO, FTO, ZnO, Al 2 O 3 or silicon oxides. suitable Alloys are, for example, Cu-Al alloys, Cu-Zn alloys and the like.

Die Schicht kann vollflächig oder partiell aufgebracht sein.The layer can be applied over the entire surface or partially.

Ferner kann eine Schicht mit optischen Merkmalen aufgebracht werden.Furthermore, a layer with optical features can be applied.

Diese Schicht kann vollflächig oder partiell aufgebracht werden.This layer can be applied over the entire surface or partially.

In einer besonderen Ausführungsform kann sowohl eine metallische als auch eine Schicht mit optischen Eigenschaften aufgebracht werden, wobei die Schichten vollflächig oder partiell, registergenau und/oder passergenau oder zumindest teilweise überlappend, aufgebracht werden.In a particular embodiment, both a metallic and a layer having optical properties can be applied, wherein the layers are applied over the whole area or partially, register-accurate and / or register-accurate or at least partially overlapping.

Auf diesen Aufbau wird eine Klebebeschichtung vorzugsweise eine Selbstklebebeschichtung, Kaltsiegelklebebeschichtung oder eine Heißsiegelklebebeschichtung aufgebracht.An adhesive coating, preferably a self-adhesive coating, cold seal adhesive coating or heat seal adhesive coating, is applied to this structure.

Mit dieser Klebebeschichtung wird das Sicherheitselement auf dem zu sichernden Gegenstand fixiert.With this adhesive coating, the security element is fixed on the object to be secured.

Wird der Aufbau mittels einer Selbstklebebeschichtung oder einer Kaltsiegelbeschichtung auf einem zu sichernden Objekt aufgebracht, so muss die Haftung zwischen den Schichten a und b größer sein als die Haftung zwischen den Schichten b und c.If the structure is applied by means of a self-adhesive coating or a cold seal coating on an object to be secured, the adhesion between the layers a and b must be greater than the adhesion between the layers b and c.

Bei Verwendung als Transferelement und Applikation mittels einer Heißsiegelklebebeschichtung ist hingegen die Haftung zwischen den Schichten a und b geringer als die Haftung zwischen den Schichten b und c.When used as a transfer element and application by means of a heat seal adhesive coating, however, the adhesion between the layers a and b is less than the adhesion between the layers b and c.

Beim einem Manipulationsversuch, insbesondere beim Versuch die Folie bzw. das Etikett vom zu sichernden Objekt abzuziehen wird die erste Lackschicht b) von der zweiten Lackschicht c) getrennt, die in die erste Lackschicht b) eingebrachte optisch aktive Struktur wird sowohl in der ersten (abgezogenen) als auch in der zweiten (auf dem zu sichernden Objekt verbleibenden) Lackschicht als Negativ erkennbar.In a manipulation attempt, in particular when trying to peel off the film or label from the object to be secured, the first lacquer layer b) is separated from the second lacquer layer c), the optically active structure introduced into the first lacquer layer b) is applied both in the first (peeled ) as well as in the second (on the object to be secured remaining) paint layer as a negative recognizable.

Wird das Sicherheitselement in Form eines Transferelements auf den zu sichernden Gegenstand aufgebracht, kann die Echtheit mittels eines Hilfsmittels, beispielsweise mittels des sogenannten Tesa-Tests nachgewiesen werden. Dazu wird ein Klebestreifen auf das Sicherheitselement aufgebracht und anschließend abgezogen. Die in die erste Lackschicht eingebrachte optisch aktive Struktur wird sowohl auf dem Klebestreifen als auch in der auf dem zu sichernden Objekt verbleibenden Lackschicht als Negativ erkennbar.If the security element in the form of a transfer element applied to the object to be secured, the authenticity can be detected by means of an aid, for example by means of the so-called Tesa test. For this purpose, an adhesive strip is applied to the security element and then removed. The optically active structure introduced into the first lacquer layer is recognizable as negative both on the adhesive strip and in the lacquer layer remaining on the object to be protected.

Zudem ist die Oberfläche der auf dem zu sicherenden Gegenstand verbleibenden Lackschicht, ebenso wie die Oberfläche des abgezogenen Teils glatt und trocken und fühlt sich nicht klebrig an (dry peel effect)In addition, the surface of the paint layer remaining on the article to be protected, as well as the surface of the removed part is smooth and dry and does not feel sticky (dry peel effect).

Das erfindungsgemäße Sicherheitselement kann als Sicherheitselement auf Verpackungsmaterialien aufgebracht werden oder in konfektionierter Form als Etiketten in beliebiger Form (eckig, rund, oval) oder als Klebeband zur Sicherung von Gegenständen oder Verpackungen verwendet werden.The security element according to the invention can be applied as a security element on packaging materials or used in ready-made form as labels in any form (square, round, oval) or as adhesive tape for securing objects or packaging.
