Definitions

  • the invention relates to a security element in the form of a thread or tape for embedding in a security document, consisting of a carrier film and at least one marking substance applied thereon, e.g. B. in the form of a coating that is used for visual and / or mechanical authenticity detection and methods for manufacturing and testing the same.
  • Such a security thread is e.g. B. from DE-OS 27 54 267, wherein a carrier film made of polyester or cellulose is coated with different materials.
  • a carrier film made of polyester or cellulose is coated with different materials.
  • visually and / or machine-readable authenticity features serve z.
  • the layer materials susceptible to mechanical abrasion and atmospheric influences such as. B. the metal coating, usually the outside of the thread.
  • the metallic coating can be easily destroyed by mechanical loads during the production of the thread, and even in later use it is often the case that the metallic coating loses its originally high-gloss property and becomes matt over time. In serious cases, the metallic layer can also be completely interrupted, as a result of which the security thread loses not only its reflective property but also its mechanically verifiable electrical conductivity over the entire length of the thread.
  • the structure is mostly asymmetrical and this asymmetry leads to the curl of the thread and the formation of garlands.
  • the thread can therefore not be embedded in the fiber layer of a forming paper layer with the same flatness.
  • the areas of the paper web in which the security thread does not come to lie in the plane of the paper layer must then be separated out as unusable. This committee makes paper production more expensive.
  • the invention is based on the object of creating a security element which, while avoiding the above-mentioned. Disadvantages can be easily produced and embedded in a security document.
  • composition of the security thread according to the invention from two foils pretreated in the same way gives the thread a completely symmetrical structure.
  • the two carrier films are preferably obtained from the same film, in which a larger film web is first provided, the corresponding coatings are provided in a coating system, the film web is then cut into two longitudinal webs and these longitudinal webs are overlaid and connected to one another in the form according to the invention. This also avoids fluctuations that could arise from the production of the film webs in two different production processes.
  • the security thread which is pulled off a roll during paper production and is guided to the paper screen at a predetermined position in the pulp, maintains its position via this path, in which it is guided freely, without rotating about its longitudinal axis.
  • the reject which arises in the case of threads with an asymmetrical structure due to the flatness of the thread being flat in the paper plane can thereby be avoided.
  • each layer containing a marking substance is present twice.
  • the absence of a marking substance in one layer does not lead to a total loss of the authenticity feature, unless the unlikely event occurs that the substance is also missing at the same location in the opposite layer.
  • the amount of substance is only half as large, but this reduction in the amount can easily be compensated for by appropriate design of the detection apparatus.
  • the two carrier foils are generally connected to one another by means of an adhesive layer, suitable adhesives being selected depending on the circumstances.
  • an adhesive material is preferably used which is permeated with electrically conductive pigments. These electrically conductive pigments electrically connect the two metal layers to one another. If there is a break in the metal layer during the manufacture of the film or when the security thread is embedded in the paper, the adhesive layer serves as a bridging element to maintain the electrical connection over the entire length of the security element.
  • resistant coatings such as, for example, B. a layer of paint or a layer of paint
  • plastic surfaces can usually be printed better than z. B. metallic surfaces.
  • the internal coatings can be made thin, since they are now adequately protected against mechanical loads by the outer plastic films.
  • the metallic layer is first applied during the production of the carrier foils and the magnetic layer is only applied to this metallic layer.
  • the metallic reflective layer thus covers the magnetic layer, which has a black or brown intrinsic color, after the two foils have been superimposed.
  • This thread can then also be stored in the printed image area of the security document, since the thread cannot be recognized or can only be recognized as a faintly bright area due to its reflecting surface in incident light and thus does not disturb the visual impression of the printed image. Only when viewed in transmitted light can this thread be recognized as a dark stripe in the paper.
  • the security threads can also be embedded in the document by methods known per se so that they appear on the surface in places. This is a particular advantage of the invention. Due to the exposed position of the security thread on the document surface, it is exposed to special mechanical loads due to daily use. In the security thread according to the invention, however, plastic layers which are resistant to mechanical and chemical influences, such as, for. B. polyester films, the outer layers that protect the sensitive feature layers. In spite of its exposed position, the thread shows no signs of wear.
  • the double presence of a marking substance can advantageously be used for authenticity testing in the case of the metallic or electrically conductive coating.
  • the carrier films are the two outer, transparent plastic films 2, 3, preferably made of polyester. Each of these plastic films is provided on its inner side with a metal coating 4, 5. For this purpose, the films are coated with an aluminum, nickel or even chrome layer by means of suitable coating processes (vapor deposition, spraying, sputtering, etc.). The layer thickness is usually far below 1 ⁇ . After their coating, these two carrier foils are connected via an adhesive layer 6. Suitable adhesives are e.g. B. laminating glue, which are activated by heating over a certain temperature range, or polymerisation glue, which harden when heated and / or UV irradiated.
  • suitable adhesives are e.g. B. laminating glue, which are activated by heating over a certain temperature range, or polymerisation glue, which harden when heated and / or UV irradiated.
  • this thread Due to its metallic coating, this thread has highly reflective properties and is therefore only recognizable as a dark stripe in transmitted light, since when viewed in incident light, the light reflected by the thread is scattered through the paper layer above it. Thanks to the outer polyester films, the thread is resistant to a large number of chemical solvents and also fulfills the required conditions such as high flexibility and tear resistance due to the excellent mechanical properties of polyester.
  • FIG. 2 shows a thread in which - again between two polyester films 8, 9 - the layer materials used for authenticity detection are embedded.
  • Each of these foils was first covered with a metallic one Coating 10, 11 provided and a magnetic layer 12, 13 is applied to this metallic coating.
  • Suitable magnetic materials or coating materials are known from DE-PS 16 69 245.
  • both of the carrier foils are overlaid with their coated side facing inwards and connected to one another with the aid of an adhesive layer 14.
  • the adhesive layer has to be coordinated with a good connection of the magnetic layers inside.
  • the films can also be coated on both sides. In this case, at least one of the layer materials then comes to the outside. Materials that withstand the chemical and mechanical loads must therefore be selected for these outer layers 15. It can be z. B. is a full-surface paint coating that has a certain color or luminescent properties. However, a pattern or alphanumeric characters can also be partially printed on, which can be read directly or with the aid of appropriate magnification devices. Since the threads usually have a width of 0.5 mm to max. 1.5 mm are required for printing the thread with characters of this size, complex printing techniques and corresponding devices, whereby the thread gains additional security against counterfeiting.
  • the two carrier foils from which the security thread according to the invention is composed are preferably obtained from a single foil which is provided with the desired layers on one or both sides in advance.
  • the side of the film that carries the later internal coatings is additionally provided with an adhesive surface.
  • these can be filled by a roller laminating system known per se (FIG. 3).
  • the two foils After passing through two press rolls 23 and subsequent cooling, the two foils are firmly connected to one another and can be cut into individual strips of the desired width in a corresponding cutting system.
