Definitions

  • the invention relates to a security element for a document of value, security paper and the like, the security element having at least one carrier film which is at least partially covered by at least one coating that is visible in reflection, the security stripe having at least one at least one layer that is at least partially recessed from the at least one coating has a longitudinal band, the longitudinal band separating a first and a second thread-forming zone, the first and the second thread-forming zone each being at least partially covered with the at least one coating, the thread-forming zones having motifs, the motifs preferably being characters, in particular alphanumeric characters and/or icons and/or geometric figures and/or symbols and/or portraits and/or landscapes and/or buildings and/or animals and/or objects and/or people.
  • Security elements of the type mentioned above are usually used in order to increase the counterfeit security of value documents or security papers, such as banknotes, identity cards, credit cards, ATM cards, tickets, etc.
  • the security elements are often partially incorporated into a document of value or security paper and can be seen in the area of windows.
  • a security element of the type mentioned is from EP2753753A1 known.
  • the motifs of the first and second zones are negative motifs which are matched to one another, ie at least one pair of these matched motifs always has the same distance difference when it is repeated along these zones.
  • a disadvantage of the known security element is that because of the coordination of the motifs, high demands are placed on the production process and production is not very flexible, expensive and prone to fluctuations.
  • the use of negative motifs imposes visual limitations in terms of perceptibility and design options.
  • motifs are designed as positive motifs or as positive and negative motifs, and/or that a first motif in the first zone and a second motif in the second zone form a pair, with a distance between the first motif and the second motif of the pair is not constant when this pair consisting of the first motif and the second motif repeats along the first zone and the second zone, or that there is no repeating pair of the first and second motif.
  • security element also includes security strips and security threads.
  • the solution according to the invention enables them to be clearly distinguished optically and thus a high potential for recognition by an observer, resulting in increased security against forgery. Due to the fact that the motifs are not "coordinated” with one another - the distances or differences in distance between pairs of motifs are not constant - there is a significant reduction in susceptibility to production fluctuations, while at the same time a very high degree of flexibility in the design options is achieved.
  • a security element can be assigned directly to a bank note, which makes counterfeiting almost impossible. Due to the fact that the motifs are not "coordinated” or due to the arrangement of pairs according to the invention, each security element can be assigned to a specific banknote.
  • the security element in particular in the form of a security strip, is applied to a substrate. This application takes place either by partial or full-area embedding during substrate production or after substrate production on the substrate, possibly also via a "window" in the substrate.
  • a characteristic match can be established at a specific position, for example a specific pair of motifs can be arranged in the first quadrant of the strip of a series of banknotes. This can be easily recorded using camera systems, for example, and stored accordingly in databases.
  • the first zone has a first division of the first motifs and the second zone has a second division of the second motifs that differs from the first division, with the first division and/or second division being preferred is a variable division.
  • the first division and/or second division is determined by the distance between immediately consecutive motifs in the same zone, in particular by a distance between immediately consecutive motifs of the same type.
  • the at least one longitudinal band can have straight or non-straight and/or parallel or non-parallel edges.
  • the security against forgery can be further increased in that the first zone has only positive motifs and the second zone only negative motifs.
  • a very high contrast is produced between the motifs of the first zone and the second zone, and the recognisability and thus the protection against forgery are significantly improved.
  • the negative motifs are formed by recesses forming windows in the at least one coating and the positive motifs are formed by the at least one coating.
  • the at least one coating in the area of the first zone is formed from at least one different material and/or has a different thickness and/or a different composition and/or a different structure than in the area of the second zone.
  • the first zone can have a different visual impression, in particular at least one different color impression and/or at least one different motif and/or another visual effect, in particular in the form of at least one color shift effect and/or at least one embossing and/or at least one hologram as the second zone.
