Definitions

  • the invention relates to a method for protecting a product against counterfeiting and a product produced by this method.
  • a common method of protecting a product against counterfeiting is the application of a mark on the product.
  • a mark on the product For this purpose, a variety of ways are known how a trademark can be connected as insoluble as possible with the product. Such characters are printed, sewn or connected as flags during sewing with the product. Frequently counterfeit products are, in particular, items of clothing. The production of cheaper copies, however, extends beyond the jewelry industry to machines and bulk goods, food etc.
  • the invention is therefore based on the object to develop a method for protecting a product against counterfeiting, which is easy to use even in the production of large quantities of product and even longer time after the mark still allows the distinction of original and plagiarism.
  • This problem is solved by a procedure in which the product is labeled with a marking substance that can be clearly and unequivocally detected by suitable analytical methods.
  • the invention is thus based on the finding that it is possible to provide on or in the product labeling substances which, without damaging the product, are as far as possible associated with the product over the entire duration of the distribution channel and thus easily detectable via random checks are.
  • the manufacturer can thus determine whether the product is an original product, so not even for counterfeiting warranty claims must be given.
  • the product is preferably doped in the context of its production process in the sense of a physical mixture. This shows that even the smallest amounts of a marking substance can be mixed into the product or parts of the product in order to distinguish original products from plagiarisms by means of such a doping.
  • the nanoparticles with a diameter smaller than 50 nanometers exhibit. Although such small nanoparticles allow a simple detection, but they do not change the product properties.
  • the product has a rare earth, optionally their oxides or salts or mixed oxides or complex salts, which among other elements also contain rare earths.
  • lanthanides in particular, have proved to be commercially available on the one hand and on the other hand as only trace amounts in the chemical or technical raw materials to be marked, and thus have proven suitable for the purpose discussed. Due to the phenomenon of lanthanoid contraction, mixed crystals or else lattice-doped crystal lattices can be produced in order to obtain a wide variety of marking substances.
  • the product isopotene, which does not occur in nature or only in traces, optionally their oxides or salts, but also mixed oxides or complex salts, which among other elements contain these isotopes. It is proposed in particular that the product does not have radioactive isotopes. In principle, actinides or other rare earths are also suitable as labeling substances, although the isotopes of the actinides may be problematical due to their radioactivity.
  • a suitable analytical method is a method by which the described labeling substances can be clearly and unequivocally demonstrated.
  • the nanoparticles mentioned can be clearly and unambiguously detected by means of mass spectroscopy and / or atomic adsorption spectroscopy (AAS), in particular also by means of ICP-MS or other plasma methods.
  • AAS atomic adsorption spectroscopy
  • ICP-MS atomic adsorption spectroscopy
  • a significant advantage of the listed labeling substances is their general indifference to various application media.
  • the marker substance is present in the material to be marked, for example in traces of from 1 to 10 ppm, via a masterbatch or a dispersion or another dosage form compatible with the application medium into the raw material from which the sale product or a part thereof is made Material without affecting its properties.
  • the substances also have very high fastness properties. Its high temperature resistance meets the highest requirements and allows, for example, use in PVC or polyolefins. They are usually UV-stable and can thus z.
  • An embodiment of the method provides that the substance of which the product is composed is marked in its entirety.
  • a paper web can be marked in its entirety. This is similar for paints, coatings, coatings, plastics or bulk materials.
  • the Markierangsmethode is especially suitable for textile fibers or oils. In the case of all these substances, the lowest levels of a marking substance are sufficient to modify the raw materials in such a way that the origin of the raw material can later be detected on the finished product.
  • a part of a product will be marked in its entirety.
  • a special component of a watch, a piece of jewelry or an electronic component can be marked in order to recognize a counterfeit on the overall product.
  • the methods are also suitable for objects of metallic character and textiles.
  • the object underlying the invention is also achieved by producing a product, in particular according to one of the preceding methods, which is labeled with a marking substance which can be clearly and unequivocally detected by suitable analytical methods.
  • the labeling substance is preferably present in traces of 0.1 to 100, more preferably between 1 and 10 ppm in the material to be labeled.
  • the marking substance in combination has several substances that can be clearly and unequivocally detected by suitable analysis methods.
  • the marker substance has a mixture of several of these substances in certain defined proportions.
  • One embodiment provides that with the aid of a nonyl phenoletoxilate in glycol, a 0.2% homogeneous dispersion of ytterbium / erbium-1: 1 mixed phosphate nanoparticles with the aid of a dispersing or mixing unit, eg a dissolver is produced.
  • This 0.2% dispersion of the marking substance becomes a coating, For example, a wood preservation glaze, added at 0.2%, so that the glaze ultimately contains 4 ppm of the marking substance. That is, 1 gram of the coating contains 1.3 ⁇ g each of ytterbium and erbium.
  • the two cited lantanoides can be determined by mass spectroscopy and / or atomic adsorption spectroscopy (AAS), in particular by ICP- MS or other plasma method, clearly and unambiguously demonstrate.
  • AAS atomic adsorption spectroscopy
  • the detection limit for ytterbium and erbium is approx. 0.1 ⁇ g / l in the graphite furnace.
