Definitions

  • the invention relates to an optically variable security element. Furthermore, the invention relates to a document of value with the optically variable security element.
  • Optically variable security elements for example on banknotes, are known from the prior art.
  • a viewer has different visual impressions depending on the viewing angle.
  • the different viewing angles can be achieved by tilting the optically variable element or a document of value with the optically variable element about an axis, while the viewing direction of the viewer and the direction of illumination of the optically variable element remain unchanged.
  • EP 3 000 613 A1 relates to an optically variable security element.
  • the optically variable security element shows a kinematic effect when tilted about the x-axis and a color change effect when tilted about the y-axis.
  • the invention is based on the object of providing an optically variable security element which enables improved security against forgery and whose authenticity can be easily checked by an observer.
  • a further object of the invention is to provide an optically variable security element that can be produced relatively easily and inexpensively.
  • An optically variable security element comprises a motif area.
  • the motif area includes a first section and a second section. At least a portion of the first portion of the subject area is brightly visible to a viewer at least at a first viewing angle. At least part of the second portion of the subject area is dimly visible at least at the first viewing angle by the viewer. At least part of a first motif of the motif area is brightly visible to the observer at the first viewing angle. The portion of the first portion of the subject area is dimly visible to the viewer at least at a second viewing angle. The part of the second portion of the subject area is brightly visible to the viewer at least at the second viewing angle. At least part of a second motif is brightly visible to the viewer at the second viewing angle.
  • a transition from the first viewing angle to the second viewing angle can be carried out by tilting the optically variable security element about a first axis.
  • a main motif of the motif area also becomes visible to the viewer through the brightly visible or dark parts of the sections.
  • tilting the optically variable security element about a second axis, which is not parallel to the first axis a kinematic effect in the motif area is visible to the viewer.
  • the first axis and the second axis are preferably perpendicular to one another.
  • Security elements can be applied to an item to enable verification of the item's authenticity.
  • an object can be, for example, a check, a bank card, a document, a deed, an identity card, a piece of clothing (a label of a piece of clothing) or a bank note.
  • At the first/second viewing angle at least part of the first/second subject is brightly visible in the first/second portion of the subject area and at a second viewing angle no part of the (corresponding) subject may be visible in the first/second portion.
  • no part of a subject can be brightly visible in another section of the subject area under the first viewing angle, and at least part of the subject is brightly visible in the other section under the second viewing angle.
  • a (sub)motif change in the motif area can be achieved by tilting the security element about a first axis.
  • the first (or the first) motif(s) as well as the second (or the second) motif(s) can also be referred to as sub-motifs.
  • a kinematic effect can be achieved by tilting the security element about a second axis.
  • the viewer thus has different effects that are particularly memorable for the viewer.
  • the tilting is preferably increased in the present case the recognizability of the main subject. As a result, the viewer can easily and reliably check the authenticity of the security element.
  • the main subject is visible to the viewer particularly at the first and second viewing angles.
  • the main motif is preferably visible from the (at least one) first viewing angle through the brightly visible part of the first motif of the at least one first section and/or through brightly visible first motifs of a plurality of first sections.
  • the main motif is visible from the (at least one) second viewing angle through the brightly visible part of the second motif of the at least one second section and/or the brightly visible second motifs of a plurality of second sections.
  • the main motif is thus represented by the brightly visible motif areas of the (one or more) first and/or (one or more) second motifs, which can optionally be referred to as sub-motifs.
  • the main motif area comprises at least the partial areas of the (one or more) sections that appear light or dark. Tilting about the first and/or the second axis improves the recognizability of the main motif for the viewer. By tilting around the first axis, he sees a change from(from) the first motif(s) to(to) the second motif(s) in the area of the main motif. Due to the tilting about the second axis, he sees in particular a relative movement of the main subject to the first and/or second subject(s). For the sake of completeness, it should be pointed out that the main motif is a separate or independent motif, so in particular the main motif can be selected independently of the first or second motif.
  • the security element can give an observer (a person) an optical impression without any aids, so that the observer can visually perceive the authenticity of the object provided with the security element without any aids.
  • An optical security element is particularly suitable for simple or everyday authenticity checks by a human.
  • the optical impression can be perceived in a wavelength range from 400 nm to 780 nm.
  • the viewer who wants to carry out an authenticity check has different optical impressions depending on the viewing angle, the viewing direction, the side of the security element or the type of viewing (top view or see through).
  • the security element can thus convey a first visual impression from a first viewing angle and a second visual impression from a second viewing angle, the first visual impression and the second visual impression being different.
  • the security element can be applied to the object to be protected, for example a banknote or a precursor of a banknote, for example as a patch (spot) or strip.
  • the security element can be configured flat.

  • the security element can be introduced at least partially into the document of value or into the security paper.
  • the security element can be introduced into the document of value or the security paper in such a way that sections of the security element are visible to an observer and sections of the security element are not visible to the observer.
