  • the object of the present invention is to further improve data carriers of the type mentioned above with regard to their circulation stability and their security against imitation, while at the same time obtaining as completely as possible the properties important for the evaluation of the authenticity of banknotes.
  • This object is achieved by the data carrier and the production method having the features of the independent claims.
  • a generic data carrier in particular a value document, such as a banknote, identity card and the like, a substrate having at least one tactile detectable security feature, wherein the relief height of the at least one tactile detectable security feature 10 ⁇ to 180 ⁇ .

  • the large relief height of the tactile detectable security feature ensures that the consumer can easily check the authenticity of the banknote according to the invention on the basis of the tactile security feature.
  • the tactility of the at least one tactile According to the invention, the detectable security feature is obtained despite the polymeric cover layer applied to the substrate with a tactile security feature on both sides of the entire surface. This finding is surprising inasmuch as the tactility of a security feature arranged on the substrate has in part been drastically reduced in the hitherto known data carriers with a tactile security feature by the double-sided covering of the substrate with a cover layer.
  • the tactile detectable security feature of the data carrier has a relief height of 20 ⁇ to 150 ⁇ , preferably from 30 ⁇ to 130 ⁇ and most preferably from 35 ⁇ to 90 ⁇ on.

  • maintaining the tactility of the security feature to the greatest extent possible is essential to the present invention. The surprising finding that the tactility of the security feature is substantially preserved by the appropriate selection of tactile security features, covering polymeric layer and corresponding manufacturing parameters will be discussed below for the individual relevant features.
  • the tactility of a high relief height security feature is maintained to a greater extent than is the case with lower relief height security features.
  • the complete or essentially complete preservation of the tactility ultimately means that he can hardly or hardly distinguish between a data carrier with a data carrier without a polymeric cover layer, at least with respect to the haptic detectability of the tactile security feature.
  • this ideal case of 100% preservation of the relief height can not always be realized in practice, maintaining tactility of about 80% will also satisfy most users of the data carrier for unique authentication of the tactile security feature.

  • the relief structure produced by electromagnetic radiation may be e.g. to be a foamable print that expands when exposed to heat to form a relief structure. It is also conceivable in this connection to apply a particularly paper-based substrate to form a relief structure in the areas exposed to radiation.

  • each imprint can be used with a relief height of greater than 10 ⁇ as a tactile feature, in particular, an offset, flexo, screen or gravure printing method is suitable. It is possible, for example, by means of a screen printing process, to provide a relief on the security substrate, which consists only of a color layer with a thickness of about 10 ⁇ to 30 ⁇ .

  • the embossed structure is well protected from external influences by the transparent imprint, which is ensured to an even greater extent by the covering polymeric cover layer.
  • a visually distinguishable from the color of the form or the film element relief by means of ink-carrying gravure or "blind embossing" (see below).
  • a gravure printing plate without color is used to produce a so-called "blind embossing.”
  • the substrate is deformed to form an embossed structure, but no congruent imprint is produced.
  • the substrate is colorless, a colorless relief is obtained correspondingly, as a result of the blind embossing produced in a pre-print or film element, a structure which is visually perceptible from the unembossed region is generally produced by means of shadowing effects.
  • tactile detectable security features can therefore be produced in the intaglio printing process, in which areas with printing and congruent embossing structure as well as blind embossed areas, which have only one embossed structure, are produced directly next to one another.

  • the film strip 4 and the security thread 2 after being covered by the polymer top layer 9a, have a tactilely detectable relief of the relief height R1.
  • R1 is defined as the height of the polymeric cover layer in the region of the covered security feature with respect to the polymeric cover layer arranged on the substrate surface (without a tactile security feature) (see FIG. 2).
  • the relief height R0 of the tactile security features arranged on the substrate 7 is substantially completely preserved even after being covered by the polymeric cover layer 9a.
  • the quotient of Rl and R0 is 1 with complete preservation of the tactility and is particularly preferably at least in the range of 0.8 to 1.
  • the user of the banknote with respect to the relief height of the tactile security feature without or with coverage by the polymeric cover layer perceive virtually no difference.
  • the tactile detectability of the security feature covered by the polymeric cover layer is ensured in each case according to the invention, while at the same time the circulation resistance and the counterfeit protection by the polymeric cover are significantly increased.
  • cover layers 9a, 9b shown in FIG. 2 cover layers can also be applied by means of very advantageous application methods, such as e.g. Curtain coating extruder coating process, or can be done by means of a Flachklebedosiersystems. Even with such methods, data carriers according to the invention can be produced with tactile, easily detectable security features, large protection against counterfeiting and high circulation stability.

Abstract

La présente invention concerne un support de données, en particulier un document de valeur, tel un billet de banque, une carte d'identité ou un document analogue, avec un substrat (7), qui présente au moins une caractéristique de sécurité (2, 3, 4, 6, 10) tactilement perceptible. L'invention prévoit que la hauteur de relief (R0) d'au moins une caractéristique de sécurité (2, 3, 4, 6, 10) tactilement perceptible soit comprise entre 10 µm et 180 µm et que le substrat (7) doté de cette même caractéristique de sécurité (2, 3, 4, 6, 10) tactilement perceptible soit recouvert des deux côtés sur toute la surface d'une couche de revêtement polymère (9a, 9b) de telle sorte que le caractère tactile d'au moins une caractéristique de sécurité (2, 3, 4, 6, 10) tactilement perceptible reste essentiellement préservé.
