Abstract

The banknote or other security document has a paper substrate (1) into which an electrode arrangement (2) is formed. The electrode arrangement reacts to an electro magnetic field. The electrodes extend (6,7) and are located in a checking unit (8). A section of the surface has an electro luminescent layer (13) that is illuminated by an externally applied background lighting.

Description

Gegenstand der vorliegenden Erfindung ist ein Wert- und Sicherheitserzeugnis mit Lumineszenzelement nach dem Oberbegriff des Patentanspruchs 1.The present invention is a value and security product with luminescent element according to the preamble of patent claim 1.

Die Herstellung und Anwendung von Elektrolumineszenzfolien und -elementen ist aus dem Stand der Technik bekannt.The preparation and use of electroluminescent films and elements is known in the art.

In der DE 43 10 082 A1 werden Elektrolumineszenzfolien vorgestellt, die aus anorganischem(n), elektrolumineszentem (n) Pigment (en) und thermoplastischem Kunststoff mittels Extrusion bzw. Koextrusion hergestellt werden. Grundsätzlich wäre die Extrusion bzw. Koextrusion eines derartigen Systems auf Sicherheitspapiere vorstellbar, doch erscheinen die grafischen Gestaltungsmöglichkeiten durch die Prozeßlogistik eingeschränkt zu sein und der gesamte Herstellprozess für die Herstellung eines Sicherheitsdokumentes und der dafür erforderlichen Anordnungen zur Echtheitsüberprüfung sehr aufwendig zu werden.In the DE 43 10 082 A1 Electroluminescent films made of inorganic (n), electroluminescent (s) and thermoplastic (thermoplastic) by extrusion or coextrusion are presented. Basically, the extrusion or coextrusion of such a system would be conceivable on security papers, but the graphical design options appear to be limited by the process logistics and the entire manufacturing process for the production of a security document and the necessary arrangements for checking the authenticity very expensive.

In der DE 43 15 244 A1 wird ein Verfahren zur Herstellung eines elektrolumineszierenden Films durch Verwendung der Sputtertechnik beschrieben. Auch dieses Verfahren wäre grundsätzlich für die Herstellung von Sicherheitsdokumenten vorstellbar, doch stellt ein derartiges Herstellverfahren einen extrem hohen Aufwand hinsichtlich der für diese Technik erforderlichen Vakuumkammern dar und ist weiters sehr schwierig in einen möglichen Fertigungsablauf integrierbar und erzeugt zudem Filmschichten, die mittels zusätzlicher spezieller Beschichtungen für die hohen mechanischen Anforderungen an Sicherheitsdokumente ausgerüstet werden müssten.In the DE 43 15 244 A1 For example, a method for producing an electroluminescent film by using the sputtering technique will be described. This method would also be conceivable in principle for the production of security documents, but such a production method represents an extremely high expenditure in terms of the vacuum chambers required for this technique and is also very difficult to integrate into a possible manufacturing process and also produces film layers, which by means of additional special coatings for the high mechanical requirements for security documents would have to be equipped.

In der DE 41 26 051 A1 wiederum wird ein Sicherheitsdokument mit eingebettetem flächenhaften Sicherheitselement (Sicherheitsfaden) vorgestellt, das mehrschichtig ausgebildet ist und elektrolumineszierende Eigenschaften aufweist. Nachteil dieser Anordnung ist, dass ein relativ hoher Flächenaufbau in Kauf genommen werden muss, denn die zur Anregung der Elektrolumineszenz-Substanzen erforderlichen Elektroden sind übereinander liegend angeordnet.In the DE 41 26 051 A1 In turn, a security document with an embedded planar security element (security thread) is presented, which is multilayered is formed and has electroluminescent properties. Disadvantage of this arrangement is that a relatively high surface area must be taken into account, because the electrodes required for exciting the electroluminescent substances are arranged one above the other.

DE 41 26 051 A1 beschreibt bereits einen vollflächigen Aufbau von Elektroden, die über und unter einer vollflächigen Elektrolumineszenzschicht angeordnet ist. Zur Anregung wird an beiden Elektrodenflächen eine Wechselspannung angelegt. Diese setzt eine ohmsche Kontaktierung der Elektrodenfläche voraus. DE 41 26 051 A1 already describes a full-surface structure of electrodes, which is arranged above and below a full-surface electroluminescent layer. For excitation, an alternating voltage is applied to both electrode surfaces. This requires an ohmic contacting of the electrode surface.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Leuchtdichte zu erreichen.The invention has for its object to achieve an improved luminance.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruchs 1 gekennzeichnet.To solve the problem, the invention is characterized by the technical teaching of claim 1.

Unterhalb einer als Echtheitselement ausgebildeten Schicht ist eine selbstleuchtende Anordnung in Form eines Lumineszenzelements vorgesehen. Dieses Lumineszenzelement dient als Hintergrundbeleuchtung für das darüber vorgesehene Echtheitselement.Below a trained as authenticity element layer, a self-luminous arrangement is provided in the form of a luminescent element. This luminescent element serves as a backlight for the authentification element provided above.

Die Anregung für die Lumineszenzelemente (13) kann durch eine Hg-Niederdruckentladungslampe, durch eine extrem schmalbandige Lichtquelle in der Form eines Lasers, insbesondere mittels Festkörperlaser, Nd:YAG Laser oder durch Excimerlaser erfolgen.The excitation for the luminescence elements (13) can be effected by means of a Hg low-pressure discharge lamp, by an extremely narrow-band light source in the form of a laser, in particular by means of solid-state lasers, Nd: YAG lasers or by excimer lasers.

Claims (7)

  1. Value and security product, consisting of a single-layer or multilayer support material, wherein an authenticity element is arranged on or within an authenticity element layer of this support material, wherein, as seen from the upper side of the value and security product, a luminescent element (13) is arranged below the authenticity element layer of the support material in such a way that, when excited, it produces a background illumination of the authenticity element arranged above it, characterized in that the luminescent element (13) is excitable by means of electromagnetic radiation, wherein the luminescent element contains luminescent substances based predominantly on Mn-activated Germanates.
  2. Value and security product according to claim 1, characterized in that the exciting wavelength range for the luminescent element (13) lies within the UV wavelength range.
  3. Value and security product according to claim 1, characterized in that the excitation for the luminescent element (13) may be provided by means of laser radiation or by means of the radiation of a low-pressure Hg discharge lamp.
  4. Value and security product according to any one of the claims 1 to 3, characterized in that the authenticity element consists of a plastic or metal foil (14) of variable structure (15) and/or colour which is placed at the support material (1).
  5. Value and security product according to claim 4, characterized in that the plastic or metal foil (14) is provided with depressions and/or holes (16), of which the authenticity features are composed.
  6. Value and security product according to claim 5, characterized in that micro lenses (22) are inserted on or in the depressions and/or holes (16).
  7. Value and security product according any one of the claims 1 to 6, characterized in that the authenticity element itself has luminescent properties.
