Definitions

  • the present invention relates to a security document and a method for producing a security document.
  • a security document usually consists of several layers, which are preferably connected to one another by lamination.
  • the data are introduced to protect against manipulation under a preferably transparent cover layer within the material. This can be done by laser personalization in the otherwise finished media.
  • Another method provides to provide the disk after personalization with a preferably transparent cover layer.
  • a security document may be alienated by removing the topcoat and applying a new topcoat after manipulating the underlying data.
  • Holograms can be used to secure the document against manipulation.
  • a special hologram foil is exposed accordingly and applied to the data carrier.
  • Examples of a hologram fuse include: WO 2017/09119 A1 . DE 10 2007 042 386 A1 and EP 2 738 624 B1 described.
  • EP1266768 and WO98 / 19869 a fuse variant is described in which a connection between the layers is produced by perforation of a pattern. The different hole geometries and diameters The perforation can be seen with backlighting an image with different brightnesses.
  • Another security variant is in EP 1 970 211 A1 disclosed. The document is laser-engraved on the narrow side surfaces to create an optical connection between the layers.
  • a security element is understood to mean a structural unit which comprises at least one security feature.
  • Security elements are used to secure security documents, which also include value documents, against counterfeiting or copying.
  • a security feature can be an independent structural unit, which can be connected, for example glued, to a security document, which can also be a value document. It can also be an integral part of a security document.
  • a security feature is a structure that can only be produced or reproduced with increased effort compared to simple copying or not at all unauthorized.
  • Security documents typically include a substrate, a print layer, and optionally a transparent cover layer.
  • a substrate is a support structure to which the print layer is applied with information, images, patterns, and the like. Suitable materials for a substrate include, inter alia, all customary materials based on paper and / or plastic in question. Examples of security documents are identity cards, passports, driving licenses, ID cards, access control cards, visas, tax stamps, tickets, motor vehicle papers, banknotes, checks, postage stamps, credit cards, any chip cards and self-adhesive labels.
  • the security document according to the invention is made up of a number of layers, of which at least one layer comprises a security element.
  • the security element has a structure comprising a plurality of structural elements.
  • the structural elements are in particular formed as depressions with respect to the surface of the security element.
  • the structural elements have dimensions, in particular diameters, of less than 200 micrometers (200 ⁇ m).
  • the structural elements preferably have dimensions in the range between 100 nanometers (100 nm) and 50 micrometers (50 ⁇ m).
  • the security element is configured as a film.
  • the security element may be the top layer of the security document.
  • the structural elements are designed as bores.
  • the structure comprises individualizing information about a holder of the security document. The thus individualizing structure with information about a holder of the respective security document improves the security against counterfeiting.
  • the design of the security element with a micro- or nanostructure has the advantage that the structure used is not immediately recognizable to the naked eye, but can be visualized by simple means, for example a microscope or by viewing at a suitable angle. Furthermore, such a security element can not be copied or forged only with considerable effort. In particular, when used as a cover layer of a security document, the surface or cover layer of the security document can not be manipulated or unnoticed separated and replaced by the remaining data carrier.
  • the security element has a periodic structure. This is useful, for example, in the context of a use for security documents, in particular value documents, which are manufactured in large numbers with predominantly identical features.
  • a film having a particular continuous periodic structure can be inexpensively manufactured for a particular type of security document.
  • the structural elements can be arranged on at least one surface of the security element or in the interior or within the security element.
  • the structural elements are preferably depressions, but may also be configured as elevations or cavities. It is also possible that the structural elements differ in terms of their optical and / or mechanical and / or chemical properties from the material of the security element. In other words, the structural elements of the material of the security element may have deviating optical, mechanical or chemical properties.
  • the variants mentioned can be combined with each other as desired. They have the advantage that they can be produced comparatively easily and inexpensively and at the same time significantly improve protection against counterfeiting.

  • This can be achieved by ground or ceiling surfaces of the structural elements are aligned as possible parallel to an extension plane of the security element and wall surfaces of the structural elements as perpendicular to the extension plane of the security element.
  • the individual structural elements may have a length and / or a width and / or a depth or a height and / or a distance of adjacent structural elements from one another of less than 200 micrometers, for example between 100 nanometers to 50 micrometers.
  • dimensions in relation to the length and / or width and / or the distance of at least 1 micrometer and depths of at least 0.5 or 1 micrometer are advantageous.
  • the dimensions in relation to the length and / or width and / or the distance are at most 20 micrometers. It is also advantageous if the depths are not more than 20 microns.
  • the dimensions mentioned require special manufacturing processes, for example, a material processing with ultrashort laser pulses, so that the security element can be replicated only with great equipment cost, which increases its security against counterfeiting.
  • the details of the structure are not immediately recognizable, which further complicates a replica.
  • the dimensions of length, width, depth and / or distance may be different from each other.
  • the structural elements are formed as recesses, they preferably have a bottom surface which has a reflection coefficient which is at most half as high as the surface of the security element between the structural elements. This can be achieved by choosing a suitable material of the security element, which has a slight blackening under the action of laser light. Likewise, good results are achieved when the structural elements are introduced into a material having a directionally reflecting surface, since, in particular when laser pulses are used for the formation of the structural elements, their bottom surface diffusely reflects. Due to the lower reflection coefficient of the bottom surface is achieved that the security element provides a vertical plan view frosted or gray overlay with the underlying information.
  • the structural elements are configured as bores, that is, as depressions with a circular cross section, for example as micro or nano laser bores. These have the advantage that they can be manufactured comparatively easily with ultrashort laser pulses.
  • the structural elements of the periodic structure may also have different shapes and / or combinations of shapes.
  • the structure can also contain superimpositions of structural elements.
  • the structural elements are covered, for example with a film or a film, in particular a lacquer layer.
  • the structural elements can be configured as depressions or cavities and filled with a material which differs from the material of the security element.
  • the material used for filling preferably has a different refractive index of the material of the security element and / or one of the color of the material of the security element deviating color.
  • the filling can be effected by means of printing processes, in particular ink jet printing.
  • inks which contain at least one polymer fraction, for example polycarbonate.
  • the use of printing methods for filling offers the advantage that the structural elements can be selectively filled in different colors.
  • the security element may be designed for a particular security document or for a particular type of security document with certain security information, the existence of which can be detected during document verification.
  • the structure may include security information for the particular security document.
  • the security element may comprise an at least partially transparent material and / or a metal layer and / or hologram film and / or polycarbonate and / or glass.
  • the structure may be located in the transparent material and / or the metal layer and / or the hologram foil and / or the polycarbonate and / or the glass.
  • the security element may be completely or partially transparent, in particular transparent to visible light.
  • the security element can also have a completely or partially transparent window and optionally non-transparent areas, wherein the structure is at least partially arranged in the window. This has the advantage that the structure can be made visible from two sides.
  • the structure may be arranged in a metallized film.
  • the security document according to the invention may in particular comprise layers interconnected by lamination.
  • the layers may be, for example, a substrate, a print layer containing security-relevant information, and a cover layer, the print layer being arranged between the substrate and the cover layer.
  • the cover layer comprises the security element. But it is also possible that at least one of the others Layers comprises a security element. In this way, the security against counterfeiting can be further improved.
  • the security document comprises a transparent window, wherein the security element is arranged in the region of the transparent window.
  • the method according to the invention for producing a security document with a security element as a layer, in particular as a cover layer of the security document comprises creating a structure having structural elements with dimensions of less than 200 micrometers (200 ⁇ m) in or on the material of the security element.
