  • banknotes with different substrates. Paper, polymer and mixed forms of paper and polymer in the form of so-called hybrid banknotes are known. For each type of banknote, special process steps are required in order to apply security elements to the banknote paper or to generate them when the banknotes are printed on the banknote paper.
  • film-based security features e.g. B. holograms, optically variable elements and / or transparent windows can be used. They are produced on foil and later applied to banknote paper in order to obtain a security substrate that can be printed on.
  • safety features are known for this purpose, which usually have at least one have relief structure generated by embossing, for example holograms, nanostructures, micromirrors, moiré magnifiers, etc.
  • the security features are film-based, and the substrate, which comprises at least one film, is applied to a security substrate as a transfer element.
  • Stripes and security threads can, for example, only be attached with their security elements in a defined, rectangular area.
  • the application of individual patches is associated with high production costs. As the number of security features increases, so does the manufacturing cost for the security substrate or the value document.
  • a document of value is known from WO 2016/096095 A1 which is composed entirely of a film body.
  • the film body consists of two foils that are connected to one another via an intermediate layer.
  • the foils On the sides facing the intermediate layer, the foils each have sub-wavelength structures. All optical views that are normally generated by printing processes and presented by the value document are now generated by these subwavelength structures. Other image-generating elements such as printing elements are deliberately excluded.
  • security substrate includes sheet-like security substrates, such as preliminary stages for printing banknotes, checks, etc. as well as comparatively rigid security unit substrates, e.g. B. preliminary stages for security, ID or payment cards.
  • the invention is based on the object of creating a security substrate and a value document in which film-based security elements can easily be combined with security elements that are generated by displaying images, etc., with the greatest possible freedom of design, without the manufacturability becoming more difficult. At the same time, a particularly good color of the appearance should be achieved.
  • the security substrate has a front and a back. It covers a certain area in plan view. It has a first carrier film which extends over at least 50%, preferably over 75% or 100% of this area.

  • a second essentially opaque layer can be provided on the side of the first relief structure opposite the first opaque layer or the first pressure acceptance layer. There is also one on this side second print acceptance layer is provided on which a second, colored printing element is formed.
  • the security substrate can be made from a single film with the first relief structure embossed and embedded in protective varnish. It is equally possible to laminate the first and second carrier films to one another. A three-film structure, of which the middle one is then the first carrier film with the first relief structure, is equally possible.

  • a paper layer can be used as the core, on the surfaces of which the foils are applied over the entire area, one of the foils then being the first carrier foil.
  • foils applied to the paper core on both sides can also have relief structures. Then the already mentioned second relief structure is provided.
  • An inversion of this structure is possible to the effect that paper layers are applied as the core to the carrier film, which carries the first (and possibly also the second) relief structure. This can be done by lamination.
  • metallizations such as aluminum, gold, silver, chromium, Cr-Al, Cr-Al-Cr or alloys come conditions, e.g. B.
  • the reflection-increasing coating can be structured laterally. This is usually referred to as demetallization and is done to reveal the effect or print elements behind.

  • the lateral structuring of the opacity of the reflection-increasing coating can create the appearance of a watermark.
  • the print acceptance layer can be an opaque white or a semi-transparent or fully transparent color acceptance layer.
  • a low grammage can particularly preferably be chosen in order to locally vary the transparency of the paper portion.
  • embossed optical effects can be made visible through the paper - in turn, a watermark is obtained.
  • cutouts are also possible in the paper. This can be done by a laser cut, etc. Another option is the use of colored mottled fibers.

Examples are hologram structures, nanostructures, micromirrors, blazed gratings, sawtooth structures, microstructures, microfocusing elements such as lenses, Fresnel lenses, concave mirrors, Fresnel concave mirrors, pinhole and slit diaphragms, each in combination with microstructures to create modulo mappers - or Moiré magnifier structures.

  • the micromirrors can be arranged in the z-direction at different height levels, as is special from DE 102018005474 A1, DE 102018005447 A1 or DE
  • laminating adhesives can be used. Colored and / or semi-transparent laminating adhesives are also possible, as are laminating adhesives that create fluorescent effects, OVI, metal flakes, etc.
  • a lamination without adhesive is equally possible, for example by melting under pressure or temperature.
  • the security elements that are formed on the security substrate using the options mentioned above can be distributed as desired over the entire security substrate.

  • the printed image can be aligned inwards, which is of course useful in the case of multi-layer structures.
  • a bare film surface can then be obtained as the outside of the security substrate, so that the security features are particularly well protected. This leads to high circulation stability.
