Definitions

  • the invention relates to a security element for protecting objects of value with at least one translucent partial area.
  • the invention also relates to a method for producing such a security element and to a data carrier equipped with such a security element.
  • Data carriers such as value or ID documents, but also other valuables, such as branded items, are often provided with security elements for protection, which allow the authenticity of the data carrier to be checked and which also serve as protection against unauthorized reproduction.
  • the security elements can be designed, for example, in the form of a security thread embedded in a banknote, a cover film for a banknote with a hole, an applied security strip, a self-supporting transfer element or also in the form of a feature area printed directly onto a document of value.
  • Metallized film security elements such as security threads embedded in banknote paper, are often provided with recesses that appear as light negative marks against a dark background when viewed through. If such negative markings are combined with machine-readable magnetic features, care must be taken that the highly pigmented, optically opaque magnetic paint does not cover the recessed areas of the negative markings, as otherwise these would be incorrectly recognized when viewed through the lens or could no longer be recognized at all. Because the available area on a security thread is severely limited, there is a conflict between negative indicia and magnetic features. Although transparent magnetic paints have also been known for some time, these contain a low concentration of a pigment and can therefore be simulated relatively easily. Due to the low pigmentation, the remanence of these transparent magnetic inks is also low and machine authentication is therefore more difficult and less reliable than with conventional magnetic inks.
  • the invention is based on the object of specifying generic security elements which can both be checked visually when viewed through and are also equipped with a reliably machine-readable magnetic authenticity assurance.
  • the security element has a multiple magnetic coding that at least partially overlaps the transparent partial area, which consists of two or more different magnetic colors and contains at least one transparent magnetic color that at least partially overlaps the transparent partial area.
  • the multiple magnetic coding contains only transparent magnetic colors.
  • the multiple magnetic coding contains both transparent and opaque magnetic colors. It is expedient provided that only transparent magnetic colors Multiple magnetic coding overlap the translucent section. In other configurations that are also expedient, at least one opaque magnetic color also overlaps the light-transmitting partial area, although it is impossible for opaque magnetic colors to cover the entire light-transmitting area.
  • the light-transmissive partial area is preferably formed by gaps in an opaque layer, in particular an opaque metal layer of the security element.
  • the transparent partial area can represent a flat partial area of the security element or even of a data carrier provided with the security element.
  • the translucent partial area can represent, for example, a window area in an otherwise opaque security element or data carrier.
  • the light-transmitting partial area forms a see-through identification of the security element that is recognizable when viewed through in the area overlapping with the multiple magnetic coding.
  • the magnetic colors of the multiple magnetic coding advantageously differ in their magnetic coercivity and/or magnetic remanence.
  • at least one magnetic color can be high coercive, in particular with a coercivity above 1000 Oe (80 kA/m) or even above 2000 Oe (160 kA/m), and at least one other of the magnetic colors can be low coercive, in particular with a coercivity below 500 Oe (40 kA/m) or even below 350 Oe (28 kA/m), especially between 20 and 100 Oe (1.6 - 8 kA/m).
  • the difference in the coercivity of the magnetic paint with the highest coercivity and the magnetic paint with the lowest coercivity strength is preferably above 1000 Oe (80 kA/m), more preferably even above 2000 Oe (160 kA/m) or even above 3000 Oe (240 kA/m).
  • At least one magnetic color can have a high remanence, in particular with a remanence flux density above 200 nWb/m, preferably with a remanence flux density between 200 and 450 nWb/m, and another of the magnetic colors can have a low remanence, in particular with a remanence flux density below of 150 nWb/m, preferably with a residual flux density between 20 and 120 nWb/m.
  • the transparent magnetic colors advantageously have a lower coercivity and remanence than the opaque magnetic colors.
  • the light transmittance of the transparent magnetic paints is advantageously above 25%, in particular above 35%, preferably even above 50%.
  • the light-transmitting partial area, and in particular gaps in an opaque layer, is/are easily recognizable with such light-transmission values even when the transparent magnetic inks overlap or are covered.
  • the magnetic inks of the multiple magnetic coding are advantageously formed by inks with magnetic components, in particular with magnetic pigments or magnetic flakes.
  • the magnetic components can also be coated or encapsulated magnetic pigments or magnetic flakes.
  • two or more magnetic colors have the same magnetic components in different have a chemical proportion in order to achieve different magnetic properties. Examples of possible magnetic components are Ni flakes, Neomag and HiCo pigments.
  • the multiple magnetic coding particularly advantageously also contains a transparent mixed ink in which both magnetic components of the first and second transparent magnetic ink are contained. If the multiple magnetic coding contains opaque magnetic colors, it is advantageously provided that the multiple magnetic coding contains not only a first and a second opaque magnetic color, each with different magnetic components, but also an opaque mixed color in which both magnetic components of the first and second opaque magnetic color are contained .
  • the opaque magnetic paints can be at least partially covered with a top layer, in particular an opaque and/or reflective top layer.
  • the transparent magnetic colors of the multiple magnetic coding can completely cover the light-transmitting sub-area, but only a partial overlapping of the light-transmitting sub-area can advantageously be provided.
  • the multiple magnetic coding advantageously specifies at least one currency, one series, one denomination, one country designation and/or one batch of the security element.
  • the multiple magnetic coding can, in particular, repeat information that is found elsewhere on the Security element or a data medium on which the security element is applied, hidden or openly attached.
  • the security element is advantageously a security band or a security thread, in particular a window security thread for partial embedding in a document of value, or a security thread for complete embedding in a document of value.

  • the invention also includes a method for producing a security element, in particular a security element of the type described above. In the method, a carrier is provided and provided with a partially overlapping multiple magnetic coding in a transparent partial area, which is formed from two or more different magnetic colors and contains at least one transparent magnetic ink that at least partially overlaps the translucent subarea.
  • the magnetic coding in a security element since the area of the light-transmitting partial area, for example a negative marking, can also be covered with magnetic inks.
  • the multiple coding allows a larger amount of data to be accommodated in the coding, on the other hand, the reliability of the automatic authentication is improved, since the use of several magnetic colors with different magnetic properties not only allows the mere presence or absence of magnetic properties to be checked, but also the Differences in magnetic properties are available for detection.
