Definitions

  • the invention relates to a forgery-proof identification feature with a color shift effect, which can be visualized by suitable detection devices.
  • WO 2004/014663 a method for the production of forgery-proof identification features consisting of at least one electromagnetic wave reflecting layer, a spacer layer and a layer formed by metallic clusters is known, wherein on a carrier substrate, a partial or full surface electromagnetic wave reflecting layer and then one or a plurality of partial and / or full-surface polymeric layers of defined thickness are applied, after which a layer of metallic clusters, which is produced by means of a vacuum-technical method or from solvent-based systems, is applied to the spacer layer.
  • the identification feature produced in this way shows a visually visible, viewing angle dependent color shift effect.
  • the object of the invention was to provide a forgery-proof identification feature which has a color shift effect, which is not visually recognizable for the time being, but can be recognized by means of suitable detection devices.
  • the invention therefore provides a forgery-proof identification feature consisting of a carrier substrate, a cluster layer, a spacer layer and a reflection layer, characterized characterized in that the cluster layer has a thickness of ⁇ 1 nm and the spacer layer of a polymer layer based on dye or lacquer systems based on nitrocellulose, epoxy, polyester, rosin, acrylate, alkyd, melamine, PVA, PVC - Isocyanate or urethane systems and the reflective layer has an optical density> 2, 5.OD.
  • the carrier substrate used is, for example, flexible plastic films, for example made of PI, PP, OPP, PE 1 PPS, PEEK, PEK, PEI, PAEK, LCP, PEN,
  • PBT PET
  • PA PC
  • COC COC
  • POM polystyrene
  • ABS polystyrene
  • PTFE fluoropolymers such as Teflon
  • the carrier films preferably have a thickness of 5 - 700 microns, preferably
  • metal foils for example Al, Cu,
  • Sn, Ni, Fe or stainless steel foils with a thickness of 5 to 200 .mu.m, preferably 10 to 80 .mu.m, particularly preferably 20 to 50 microns serve.
  • Films can also be surface-treated, coated or laminated, for example with plastics, or painted.
  • carrier substrates pulp-free or cellulose-containing paper, heat-activatable paper or composites with paper, for example composites with plastics having a weight per unit area of 20-500 g / m 2 , preferably 40-200 g / m 2, may also be used.
  • the metallic clusters may consist, for example, of aluminum, iron, gold, palladium, platinum, chromium, silver, copper, nickel and the like or their alloys, such as, for example, Au / Pd or Cr / Ni.
  • This cluster layer can be applied by sputtering, (for example ion beam or magnetron) or evaporation (electron beam), from a solution or by adsorption all over or partially.
  • the cluster layer has a thickness of ⁇ 1 nm, otherwise the tilting effect will be visible sooner.
  • the following polymeric layer or layers can also be applied over the entire surface or partially.
  • the polymeric layers consist for example of dye or paint systems based on nitrocellulose, epoxy, polyester, rosin, acrylate, alkyd, melamine, PVA, PVC, isocyanate or urethane systems.
  • This polymeric layer essentially serves as a transparent spacer layer but, depending on the composition, can be absorbent in a specific spectral range.
  • the polymeric layer has a defined thickness, preferably 10 nm to 3 ⁇ m, more preferably 100-1000 nm. If several polymeric layers are applied, these layers can each have different thicknesses.
  • the polymeric layer may be applied by any coating method such as brushing, painting, casting, spraying, printing (screen, gravure, flexographic, or digital printing) or roller coating.
  • the polymeric layer can be applied over the entire surface or partially.
  • This layer may preferably consist of metals such as aluminum, gold, chromium, silver, copper, tin, iron, palladium, platinum, nickel and their alloys, for example nickel / chromium, copper / aluminum gold / palladium and the like.
  • the electromagnetic wave reflecting layer may be full-surface or partial by known methods such as spraying, sputtering, sputtering, printing (Gravure, flexo, screen, digital printing), painting, roller application method and the like are applied.
  • This reflective layer has an optical density greater than 2.5 O.D. on and forms a mirror at the back of the construction.
  • the detection system may also include an array of three mirrors within a cube shape.
  • This color shift effect is dependent on the layer thickness of the polymer layer and the cluster layer.
  • a release layer can be applied between the carrier substrate and cluster layer.
  • an adhesion promoter layer and an adhesive coating may be present on the reflection layer.
  • the structure can be easily transferred to other substrates.
  • partial structures such as motifs and the like in the form of patches can be transferred to other substrates.
  • the security features according to the invention where appropriate after appropriate fabrication (for example into threads, strips, patches or other formats), can therefore be used as security elements on data carriers, in particular value documents such as identity cards, cards, banknotes or labels, seals and the like, but also in packaging material for sensitive goods. such as pharmaceuticals, cosmetics, data carriers, electronic components and the like.
