Definitions

  • the invention relates to a method for counterfeit-proof marking of objects such as check cards, banknotes, packaging and the like. It also relates to a tamper-proof mark.
  • the object of the invention is to provide a method for marking objects and a marking, which offer a high degree of protection against forgery in a simple and cost-effective manner.
  • a method for the counterfeit-proof marking of objects such as check cards, banknotes and the like., Is provided according to claim 1.
  • a forgery-proof permanently visible mark can be produced in a simple and cost-effective manner.
  • the second layer is applied structured in the process.
  • the structuring is a structure in the surface in the manner of a pattern or a drawing. It is also a relief-like structure. In this case, the marker appears in different colors.
  • An electromagnetic fourth wave permeable fourth layer is applied to the third layer.
  • the fourth layer serves primarily to protect the covered layers.
  • the substrate may be made of an electromagnetic wave transmissive material, preferably of glass or plastic.
  • first molecules which are affine to the second layer or to second molecules provided thereon.
  • polymers, silanes or structurally related compounds can be used as molecules.
  • complementary polynucleotide sequences, such as DNA as molecules.
  • the function of the first and second molecules is essentially to adhere the substrate to the marking at a fixed predetermined distance.
  • the metallic clusters can be made, for example, from silver, gold, platinum, aluminum, copper, tin or indium.
  • the second layer is made of one of the following materials: polymer, especially polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyurethane (PU), polyimide (PI), polystyrene (PS) or polymethacrylate (PMA). These materials are chemically substantially inert. They are insensitive to moisture.
  • the function of the second layer is essentially to permanently provide a predetermined distance to the third layer and a predetermined structure.
  • the first layer can be irradiated by means of a device for generating electromagnetic waves, preferably by means of LASER, fluorescent lamp, light-emitting diode or xenon lamp.
  • the marker may be identified by means for determining the optical properties of the electromagnetic waves reflected from the first layer. It can be measured with the means for determining the optical properties of the absorption, preferably at different observation angles. Such a determination of the optical properties allows a high security against counterfeiting.
  • the layers are at least partially produced by means of thin-film technology.
  • vacuum coating technologies and the like come into consideration.
  • At least one of the layers is made of a material having an anisotropic refractive index.
  • the second layer is made of an anisotropic refractive index material.
  • the material may be e.g. to be liquid crystal polymers which are stable at different observation angles, i. Angles to the z-axis, as well as at different angles of rotation, i. Angles in the x-y plane, showing a characteristic coloration.
  • At least one of the layers can be made of a material whose optical properties can be selectively changed after the application of the layer.
  • the material may be e.g. to be a photosensitive polymer whose refractive index is variable by irradiation with a suitable wavelength.
  • an electromagnetic wave reflecting first layer is designated 1. It can work to a metal foil, such as an aluminum foil act.
  • the first layer 1 can also be a layer formed from clusters which is applied to a carrier 2.
  • the carrier 2 can be the object to be marked.
  • the clusters are suitably made of gold.
  • the second layer 3 has a structure.
  • the structure is in the form of a relief which is e.g. designed in the manner of a bar code.
  • the thickness of the second layer is preferably between 20 and 1000 nm. It is applied by means of thin-film technology. For this purpose, e.g. Vacuum coating process.
  • a third layer 4 made of metallic clusters is applied on the second layer 3.
  • the third layer 4 in turn is superimposed by a fourth layer 5.
  • the fourth layer 5 protects the underlying layers from damage.
  • the fourth layer 5 may be made of a chemically inert and optically transparent material, eg a metal oxide, nitrite, carbide or polymer.
  • the in the 3 and 4 Marks shown are only visible when they are brought into contact with a substrate 6, on the surface of which the third layer 4 formed of metallic clusters is applied.
  • the third layer 4 may be superposed with a fifth layer 7 formed of first molecules.
  • the fifth layer 7 is expediently formed from molecules which are affine to the material of which the second layer 3 is made. Upon contact of the fifth layer 7 with the second layer 3, a specific adhesion thus occurs. It may also be that the second layer 3 is covered with a further fifth layer 7.
  • the fifth layers 7 are each formed of molecules having affinity to each other. These may be biopolymers which are complementary to each other.
  • the fifth layer 7 can also be made of other polymers, silanes and / or structurally related compounds.
  • the substrate 6 is made of a transparent material, e.g. made of glass or plastic.
  • optically transparent second layer 3 is applied to the electromagnetically reflecting first layer 1.
  • the marking is initially not visible.
  • the optically transparent substrate 6 provided with the third layer 4 When the optically transparent substrate 6 provided with the third layer 4 is applied, an interaction between the light reflected at the first layer 1 and the third layer may occur. This in turn results in a color effect, which is observable by the substrate 6, preferably made of glass.
  • the third layer 4 may be covered with a fifth layer 7.
  • the substrate 6 adheres to the marking. It sets a predetermined distance between the third layer 4 and the first layer 1 a.
  • Fig. 5 shown spectra of a marker according to Fig. 1 were measured using a Lambda 25 UV / VIS spectrometer from Perkin Elmer using a reflection insert.
  • Fig. 5 It can be seen that the longer-wave peak shifts toward shorter wavelengths with increasing observation angle. Furthermore, a fixed peak can be observed, which is due to the silver clusters.
  • Fig. 6 is a quantitative evaluation of the spectra according to Fig. 5 each shown at two different wavelengths. At the considered wavelengths, a changed absorption is observed depending on the observation angle. The absorption pattern is characteristic of the authenticity of the label.
