Definitions

  • the invention relates to a security element for securities or security papers, wherein the security element has an embossing with diffractive embossed structures.
  • valuable documents and security papers are understood to mean, in particular, banknotes, passports, identity cards, travel tickets, tickets for events, securities, etc.
  • the object of the present invention is to create an embossed security element whose security against counterfeiting is further increased.
  • embossed structures are at least partially coated with a partial, metallic layer forming a mosaic-like image, wherein a partial layer is understood here to mean a layer that is interrupted and thus only partially exists as a closed layer.
  • embossed structures By combining the embossed structures with a mosaic-like image, an image with a three-dimensional impression that is recognizable to the viewer can be created, which significantly increases the security against counterfeiting.
  • the embossed structures are designed as achromatic embossed structures.
  • the embossed structures form a relief that is coordinated with the mosaic-like image.
  • the embossed structures can correspond to a three-dimensional reproduction of an image underlying the mosaic-like image or a motif of the mosaic-like image.
  • the embossed structures can form a bas-relief.
  • An example of a bas-relief is the embossing of a coin.
  • the embossed structures can be designed to be translucent.
  • the security element has a carrier film made of plastic, in particular of translucent plastic.
  • the carrier film and/or the embossed structures are made of one or more materials selected from the group polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene (MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), polyether ketone (PEK), polyethylene imide (PEI), polysulfone (PSU), polyarylether ether ketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), ethylene te

  • the mosaic-like image is formed from image elements which are of different size and shape, wherein a image element is formed by a continuous area of the layer forming the mosaic-like image and wherein the layer forming the mosaic-like image is interrupted between two image elements.
  • image elements of different sizes correspond to different mosaics of the mosaic-like image.
  • the regions interrupting the mosaic-like image-forming layer are formed by demetallization.
  • the carrier film can have a thickness between 5 - 700 ⁇ m, preferably 5 - 200 ⁇ m, particularly preferably 5 - 125 ⁇ m, in particular 10 - 75 ⁇ m.
