Definitions

  • the present invention relates to method of producing a data carrier, to a data carrier produced thereof and to a security document comprising or consisting of such a data carrier.
  • Data carriers for security documents such as identity cards, passports or the like typically comprise at least one security element.
  • Said security element can be provided on a top surface of the data carrier.
  • Well-known method to protect data is surface embossing made by lamination plates. The weakness of such method is the fact that the security feature can be copied, removed and/or replaced. It is also possible to produce look-alike surface embossing by means of desktop printing, combination of glue & suitable particles, etc. Thus, such security elements are prone to forgery.
  • a method of forming a data carrier for a security document comprising:
  • This method allows forming a security feature fully inside the data carrier, said security feature surviving in lamination, leaving a pre-made and designed deformation at the interface between some of the layers.
  • This first security feature can also be referred to as an interfacial security feature, as it is located at the interface between some of the layers of the data carrier.
  • the security feature is inside the data carrier, removal of data becomes more complicated, as grinding of the data carrier would remove simultaneously also the designed deformation.
  • the first deformation is formed before forming the stack structure of the data carrier by lamination, a modification of said first deformation and the corresponding security feature after the lamination step would be particularly difficult for a forger. Therefore, the security feature is less prone to copy, reproduction or modification by a forger.
  • the data carrier obtained by this method allows subsequent personalization such as laser engraving.
  • this method of marking the data carrier does not interfere with embossing or diffractive surface elements in a negative way. It enables various possibilities in terms of design and feature visibility, it can be overt or covert, if required. Finally, this method can leave the outer surface of the data carrier fully smooth and intact.
  • Ultrasonic welding corresponds to a process that uses mechanical vibrations in the ultrasonic range. These vibrations, produced by a sonotrode, as it is generally known, are used to act on at least part of deformed layer, whereby the first deformation is produced. To this end it is preferred that the deformed layer is placed on an anvil as it is known in the art as well, and wherein the sonotrode is pressed onto the layer on a side being opposite the anvil.
  • the ultrasonic welding is preferably performed using an ultrasonic welding device as it is known in the art.
  • the ultrasonic welding device is preferably commercially available.
  • the first security element is preferably produced by applying vibrations having a frequency in the range of 1 kHz to 100 kHz, preferably in the range of 20 kHz to 70 kHz. Additionally or alternatively the first security element is preferably produced by applying vibrations having an amplitude in the range of 1 micrometer to 100 micrometer, preferably in the range of 5 micrometer to 50 micrometer. Additionally or alternatively the first security element is preferably produced during a welding time in the range of 0.05 second to 1 second, preferably in the range of 0.1 second to 0.5 second.
  • the data carrier according to the invention comprises at least one replicated deformation induced by the first deformation.
  • the at least one replicated deformation is at the interface between at least some of the layers of the data carrier.
  • the revealing layer comprises a replicated deformation.
  • the data carrier comprises at least one inner layer.
  • Said inner layer preferably comprises the first deformation.
  • the revealing layer increase and/or improve the visibility of the first deformation and the security feature once the stacked structure of the data carrier is formed. Visibility means that deformation can be observed by one way or the other. Possible means of detection methods of normal light, sidelight, see-through light, UV light is used, or a crosscut is made, or polarization films are used. Usable devices are bare eyes, loupe, microscope, etc.
  • the revealing layer is preferably selected with respect to the internal layer with the first deformation.
  • the chemical composition and physical properties of the revealing layer are not identical with those of the inner layer with the first deformation.
  • the revealing layer advantageously faces the first deformation of one of the layers such that said revealing layer is in contact with the first deformation of one of the layers.
  • the revealing layer can also face the rear side of the layer with the first deformation on its front side.
  • the revealing layer can also be separated from the first deformation of one of the layers by some inner layers in between.
  • a security element being inspectable by the bare human eye is understood as being verifiable without the need of any dedicated equipment.
  • a machine-readable security element is understood as being verifiable by means of dedicated equipment, e.g. by means of a mobile phone that takes a photograph of the security element and being configured to perform a software-based verification of the pattern.
  • a phone operates in visible light regarding the light source as well as the capture.
  • the verification could likewise require specific lighting conditions such as ultraviolet lighting or infrared lighting, and the same applied to the capturing device.
  • the verification could require magnification of some level if the security element is provided at very high resolution.
  • the at least one revealing layer comprises offset inks and varnishes, silk screen printing inks and varnishes, DOVID (Diffractive Optically Variable Image Device), OVI (Optically Variable Ink), pearlescent inks, metallic inks, metallic foils, and/or a colored plastic film.
  • DOVID Denractive Optically Variable Image Device
  • OVI Optically Variable Ink
  • pearlescent inks metallic inks
  • metallic foils metallic foils
  • a colored plastic film a colored plastic film.
  • the nature of the revealing layer is advantageously selected depending on the nature of the layer with the first deformation.
  • the data carrier comprises a so-called core layer comprising the first deformation.
  • the core layer is an inner layer of the data carrier.
  • the core layer is preferably substantially at the center of the stacked structure.
  • Said core layer can also comprises several sub layers.
  • the first outer layer and/or the second outer layer may be formed by different material adapted for their use in security documents and data carrier such as PVC, PETG, ABS and so on.
  • the first outer layer and/or the second outer layer comprises thermoplastic material.
  • the first outer layer and/or the second outer layer comprises polycarbonate.
