Definitions

  • the invention relates to a security element for a data carrier, in particular a number, legitimacy or identity document, having a substrate on which is arranged at least one moiré pattern which contains a coded pattern or image which is visible through a filter.
  • the invention also relates to a data carrier with such a security element, a semi-finished product for producing a data carrier and a method for producing a data carrier.
  • Security elements are known, for example, with credit or identity cards and serve to secure them against forgery or imitation or manipulation. Since, however, it is known that counterfeiting methods are constantly improving, it is necessary to provide new security elements which make counterfeiting more difficult. Such security elements should be designed so that they are suitable for mass production and do not affect the requirements for the performance characteristics of the data carrier.
  • the filter is arranged on a layer which is fixedly connected to the substrate, a fixed and specific distance being present between the moiré pattern and the filter.
  • the filter is firmly connected to the Moire pattern and thus can not be moved.
  • the hidden image is thus visually recognizable even without additional film.
  • the optical effect achieved is also completely different.
  • the movement of the image is not effected by movement of the filter, but by tilting the security element or the data carrier in which the security element is integrated. What is essential is the said specific distance between the moiré pattern and the filter. When tilted, the image moves continuously rather than in steps.
  • the pattern is incorporated as a whole and not composed of individual images, as is the case with conventional so-called tilt images.
  • two or more patterns or band moiré patterns may be combined.
  • Such tilts are known for example in greeting cards for children and for example in the US 6,288,842 and the EP 1 168 060 A disclosed.
  • said distance is determined by the thickness of said layer.
  • the layer may be formed by one or more films.
  • the layer is preferably transparent. The bigger the distance between the moiré pattern and the filter, or the finer the reproduction, the greater the visible movement of the image and the more complex images are possible. The movement of the image does not arise here by a displacement of the above-mentioned film, but by different viewing angles to the surface of said layer.
  • the substrate is preferably bonded to said layer by lamination.
  • the moiré pattern is preferably printed on the substrate.
  • the filter can also be printed, in particular on the top of said layer. For example, and in particular a screen printing or offset printing is suitable as a printing process.
  • Said filter is according to an embodiment of the invention, a line filter, which is preferably printed on said layer.
  • a line filter can be produced very inexpensively in series. He also has the advantage that he does not change the surface structure and thus a flat surface is possible.
  • the period of the line filter differs from the period of the pattern or moiré pattern, it can be both larger and smaller.
  • a line filter can be made very inexpensively and allows the pattern to be made with a laser beam through it at a constant angle of incidence on the substrate.
  • the pattern may be a pattern, as is common in tilt pictures, or may be a moiré pattern or a band moiré pattern.
  • the substrate consists of a laserable material. It has been found that in this case a very high opacity of the non-transparent parts of this filter is particularly advantageous.
  • black, gray or white filters are used. However, other filter colors are conceivable.
  • a polarizing filter is used.
  • the moiré pattern is produced after connecting the substrate to the layer with a laser.
  • the filter is applied to the layer, for example, as mentioned above imprinted.
  • This filter is here designed so that it is laser-transparent.
  • This layer is thus not only transparent, but also transparent to laser beams.
  • a laser-capable material is arranged, which discolored upon impact of the laser beams and thereby the pattern can be formed.
  • this pattern or moiré pattern can be personalized here. In principle, the same movement sequences as mentioned above are possible in this embodiment.
  • the filter is formed by a lenticular grid, which can be produced for example by an embossing process on top of said layer.
  • the lens structure of said filter also has the said distance from the pattern, which is arranged in the interior of the security element.
  • the lens structure acts as a filter which reveals the said hidden image of the pattern so that it is visually directly visible. Also in this case, the image moves continuously when the security element is tilted.
  • two or more band moiré patterns may be combined.
  • the lens structure can be applied either directly during lamination or in a subsequent embossing process.
  • a particularly high security against counterfeiting can be achieved if the pattern is a moiré pattern and in particular a band moiré pattern.
  • FIG. 1 schematically shows a data carrier 1 which is, for example, a credit card or identity card, an identity card or a so-called data tag in a passport or otherwise a document.
  • the data carrier 1 has a substrate 2 which, for example, is a film made of plastic, for example polycarbonate or else a suitable material.
  • a layer 3 is connected to the substrate 2, for example by the layer 3 being laminated onto the substrate 2.
  • the layer 3 is fixed and preferably inseparably connected to the substrate 2.
  • the layer 3 may also be single or multi-layered. It is transparent at least in the area of a security element 7.
  • the layer 3 has an upper side 4, to which in principle a further transparent layer not shown here or a transparent lacquer or the like can be applied. This upper side 4 is preferably parallel to a lower side 6 of the substrate 2.
  • the security element 7 consists of a band moiré pattern 10 or a conventional moiré pattern, which is arranged on an upper side 5 of the substrate 2 or on an underside of the layer 3 and a filter 12, which is in particular a line filter. As shown in FIG. 1, the filter 12 is at a distance from the band moiré pattern 10 above it arranged. It consists according to FIG. 4 of opaque lines 14 and transparent likewise line-shaped parts 15. The opaque lines 14 have a comparatively very high opacity and are applied on the upper side 4, for example by analog printing method, in particular screen printing or offset printing, or for example digital printing method. The lines can also be inserted as additional elements between the substrate 2 and the layer 3. According to FIG.
  • the opaque parts 14 and the transparent parts 15 may be straight and mutually parallel parts, but they may also be formed as other mathematically describable shapes, such as circles or spirals or wavy lines. However, the distances between the opaque parts 14 of the filter are the same here.
  • the tape moiré pattern 10 is printed on the top 5 of the substrate or printed on the bottom 6 of the layer 3 or inserted between the substrate 2 and the layer 3.
  • this band moiré pattern 10 is not viewed through an applied film but through the filter fixedly and spaced from the band moiré pattern 10.
  • the band moiré pattern 10 contains an image, which is hidden in itself and is visible through the filter 12. If the data carrier 1 is tilted, this image moves continuously. For example, the data carrier 1 can be tilted so that the viewing direction changes from line L1 to line L2.
  • an image A (not shown here) becomes visible here, for example, while when viewed in the direction of the line L2 an image B (not shown here) is visible.
  • the pattern moves continuously from position A to position B.
  • the optical effect thus differs substantially from the known tilt effect, in which either an image A or an image B is visible.
  • security element 7 thus takes place during tipping a flowing or continuous transition.
  • FIG. 5 the arrangements shown in FIG. 5 are required.
  • a viewer 19 should be one third of a moire Tile Period visible. This third corresponds here to 2r and the Moiré Tile Period 6r.
  • the Base Band Period (also known as Moire Tile Period) is the height of the pattern repeating in a band moiré pattern. A band moiré pattern image consists of repetitive identical patterns. The smaller the distance h, the finer the band moiré pattern 10 should be to obtain a satisfactory optical effect.
  • the distance h is at least 0.025 mm and preferably at least 0.05 mm. Preferably, the distance h is 0.1 mm or larger.
  • FIG. 2 shows a data carrier 1 'which likewise has a substrate 2' and a layer 3 '.
  • the layer 3 ' is also fixedly connected to the substrate 2', for example by lamination.
  • the filter 12 may be the same as mentioned above.
  • the filter 12 is here in particular also a line filter which has been applied to the layer 3 ', for example by a screen printing or offset printing method.
  • the data carrier 1 ' has a security element 8, in which a band moiré pattern 11 is provided, which was produced only after the bonding of the layer 3' to the substrate 2 'with a laser.
  • the filter 12 is designed so that it is laser-transparent. This also applies to the layer 3 '.
  • the substrate 2 ' is made of a laserable material. Such materials are known per se and are discolored when incident laser beams. The effect and the conditions are similar or the same as explained above in FIGS. 1 and 5 for this security element.
  • a significant advantage of this security element 8 is that it can be made individually and personal.
  • the band moiré pattern 11 may include, for example, an identification number or other personal information of the owner of the data carrier 1 '.
  • the band moiré pattern 11 is preferably produced only during the personalization of the data carrier 1 '.
  • other data can be applied outside the security element, for example, printed or also applied with a laser.
  • the data carrier 1 ' is thus first produced only with the filter 12. There is thus produced a semi-finished product which the band moiré pattern 11 does not yet contain. This semifinished product can be stored until the data carrier 1 'is personalized and in particular the band moiré pattern 11 is produced as mentioned with a suitable laser device.
  • the 3 shows a data carrier 1 "which has a substrate 2" and a layer 3 ".
  • the data carrier 1" is provided with a security element 9, which consists of a band moiré pattern 16 and a filter 13.
  • the band moiré pattern 16 may be formed the same as the pattern 10 or 11 and is thus likewise integrated in the data carrier 1 "
  • the layer 3" is likewise transparent and may be single-layered or multi-layered.
  • the filter 13 is designed here as a lens structure. This can be embossed either directly when laminating the layer 3 "or in a subsequent embossing process on the top of the layer 3". As can be seen, the filter 13 is applied to a portion of the top of the layer 3 "and above the band Moire pattern 16.
  • the filter 13 thus does not extend over the entire top, as is the case with the known tilt images Filter 13 is also integrated directly into the data carrier 1 "in this case. In this case, too, a smooth movement of an image becomes visible when tilting the data carrier 1.
  • the conditions here are essentially the same as explained above with reference to FIGS.
