  • security threads or - Stripes for example made of a metal coated Plastic can exist in security papers, in particular wide for use in banknotes and similar securities common. If these security threads or strips, for example be embedded in the security paper and this If necessary, these security elements can then be printed not easily recognized when the object is in Reflection is considered. But they appear as a dark shadow, when the object is illuminated and thus in transmission is observed.
  • WO-A-98 01817 There are used as security elements for security objects Photoluminescence polarizers are used, in which the emitted Luminescent light is linearly polarized. This light is through a polarizer viewed through and rotated, the viewer has a light-dark effect due to the polarizer either depending on the rotary position transmitted or not transmitted luminescent light.
  • US-A-5,284,364 uses polarizers for security purposes, but they are "ordinary" polarizers such as ⁇ / 2 plates and no photoluminescent polarizers.

  • security paper refers to security items that consist essentially of paper.
  • the polar axis of a linear polarizer or analyzer is the direction of the electric field vector of light that is transmitted through the polarizer or analyzer.
  • the polarization axis of a segment or - if applicable as appropriate - security elements or another object is the direction of the electric field vector of light which is emitted or absorbed by the corresponding segment, security element or other object.
  • a segment is a part of an object, in particular a security element, on which the characteristic degree of polarization and the polarization axis for the emission and absorption are adequately determined can be.
  • the degree of polarization for the emission is expressed by the dichroic ratio in emission ; however, this is not part of the invention.

  • the Security element can have various forms, for Example, but not only, fiber, thread, rod, film, sheet, layer, Ribbon, plate, disc, snippet and / or combinations thereof.
  • security elements in more complex forms for example, but not only, logos, letters, characters, numbers etc. be used.
  • the surface can also be used, for example of the security element are structured, for example by Printing or embossing.
  • Essential characteristic of Security article according to the present invention is the Fact that the security element is at least one has a photoluminescent segment which is linear polarized Absorption is characterized.
  • linearly polarized absorption of such segments causes that to be linear polarized excitation light which, for example, by a external light source in connection with a linear polarizer can be generated by the segment depending on the orientation of the Polarization axis of the segment and the polarization direction of the Excitation light, is absorbed to different degrees, which is the case with the Viewing through the naked eye to a strong light / dark Contrast can result.
  • a part becomes a segment an object, in particular a security element, at which the characteristic degree of polarization for the Absorption can be determined adequately.
