Definitions

  • the invention relates to a security element for securing valuables, a method for producing such a security element as well as a security paper and a data carrier with such a security element.
  • Security elements for the purpose of security, which permit verification of the authenticity of the data carrier and at the same time serve as protection against unauthorized reproduction.
  • security elements can be embodied, for example, in the form of a security thread embedded in a banknote, a covering film for a banknote with a hole, an applied security strip, a self-supporting transfer element or else in the form of a feature area applied directly to a value document.
  • the security elements are equipped with optically variable elements that give the viewer a different image impression under different viewing angles and, for example, show a different color or brightness impression and / or another graphic motif depending on the viewing angle.
  • the object of the invention is to further improve a security element of the aforementioned type and in particular to provide a security element with an attractive visual appearance and high security against counterfeiting.
  • a security element of the aforementioned type contains a thin-film element with a color-shift effect
  • a semi-transparent ink layer which is arranged in first regions above the thin-film element, wherein the color impression of the
  • Thin film element is adapted to the color impression of at least a portion of the semi-transparent ink layer when viewed under predetermined viewing conditions
  • a transparent phase retardation layer disposed in second regions over the thin film element and forming a phase shift layer for light from the visible wavelength range.
  • a combination of different color ranges is thus used, which act very similar from a certain viewing direction, but behave differently when the security element is tilted.
  • the color impression for the observer changes when the security element is tilted, while the covered regions remain substantially color-constant.
  • Such a combination of color-constant and color-variable areas has a visually attractive appearance and is self-explanatory for the user since the color-constant areas simultaneously form a visually quiescent pole and a comparison point for the color-variable areas in the authenticity check.
  • the combination of two color effects in the immediate vicinity makes it difficult to adjust the security element, since freely available colors or foils with color-shift effects can no longer be used directly.
  • the security element according to the invention contains a hidden security feature which can only be recognized by auxiliary means and which is formed by the transparent phase delay layer arranged in second areas.
  • Phase-retarding layers which in the context of this description are also sometimes called phase-shifting layers, are optically active layers which act on the phase of a transmitted light wave. Due to different refractive indices, the partial beams of an incident polarized light wave receive a path difference and thus a phase difference. If the phase difference of the two partial beams is just half or quarter wavelength, so-called ⁇ / 2 or ⁇ / 4 layers are obtained.
  • the phase delay of the phase retardation layer in the invention corresponds to a retardation between about ⁇ / 6 and about ⁇ / 2, more preferably between about ⁇ / 4 and about ⁇ / 2.
  • the path difference is modulo ⁇ , ie in the range between 0 and ⁇ indicated, since a layer with a path difference, for example, of 5/4 * ⁇ or 9/4 * ⁇ generates the same phase delay as a ⁇ / 4 layer.
  • the phase-shifting layer is formed from nematic liquid-crystalline material and / or that the phase-delay layer is in the form of patterns, characters or a coding.
  • the semitransparent color layer preferably has a light transmittance between 30% and 95%, more preferably between 60% and 95% and very particularly preferably between 80% and 95% % on.
  • the semitransparent ink layer can be applied in various ways, and is advantageously imprinted, for example in screen-printing, gravure printing, flexographic printing or another suitable printing process.
  • the semitransparent ink layer can be printed directly on the thin-film element, but it can also be provided between the ink layer and thin-film element and transparent intermediate layers, for example, act as a protective layer or adhesive layer. It is also possible to provide such transparent intermediate layers between the color layer and the phase delay layer.
  • the semi-transparent ink layer is in preferred embodiments in the form of Characters, patterns or encodings. This also includes designs in which the color layer has recesses in the form of characters, patterns or codes.
  • the semi-transparent ink layer is selected such that it substantially preserves the polarization state of transmitted light from the visible wavelength range.
  • the patterns, characters or codes formed by the phase retardation layer can be made equally visible both in the color-variable and in the color-constant regions, as explained in more detail below.
  • the semitransparent ink layer can also have several subregions with different color impressions, in which case the color impression of the thin film element is adapted to the color impression of at least one of the subregions when viewed under predetermined viewing conditions.
  • a particularly appealing effect can be achieved if the thin-layer element and the semitransparent ink layer are matched to one another such that, when the security element is viewed vertically, the color impression of the thin-film element outside the first regions essentially corresponds to the color impression of at least one subregion of the semi-transparent ink layer.
  • the color-variable and the color-constant areas initially convey essentially the same color impression.
  • the color impression changes in the color-variable regions while remaining unchanged in the color constant covered regions.
  • the thin-film element has a reflection layer, an absorber layer and a dielectric spacer layer arranged between the reflection layer and the absorber layer.
  • the color shift effect in such thin-film elements is based on viewing angle-dependent interference effects due to multiple reflections in the different sub-layers of the element.
  • the path difference of the light reflected at the different layers depends on the one hand on the optical thickness of the dielectric spacer layer, which determines the distance between the absorber layer and the reflection layer, and on the other hand varies with the respective viewing angle.
  • the path difference is on the order of the wavelength of the visible light, the result is an angle-dependent color impression for the viewer due to the extinction and amplification of certain wavelengths.
  • a multiplicity of different color-shift effects can be designed, for example tilting effects in which the color impression changes with the viewing angle from green to blue, from blue to magenta or from magenta to green.
  • the reflection layer of the thin-film element is preferably formed by an opaque or by a semitransparent metal layer, in particular aluminum.
  • a reflection layer an at least partially magnetic layer can also be used so that a further authenticity feature can be integrated without requiring an additional layer in the layer structure.
  • the reflective layer may further comprise recesses in the form of patterns, characters or codes that form transparent or semi-transparent regions in the thin-film element. In the transparent or semi-transparent recessed areas, the observer has a conspicuous contrast to the surrounding color effects.
  • the patterns, characters or codes can light up brightly in transmitted light when the thin-film element is applied to a transparent or translucent carrier.
  • the recesses in the reflection layers can also be grid-like, preferably with a small surface area of 40% or less, so that they are practically inconspicuous in reflected light and only appear in transmitted light.
  • the thin-film element can also be formed by superimposed absorber layers and dielectric spacer layers, it also being possible for a plurality of absorber and spacer layers to be arranged alternately one above the other.
  • Such thin-film elements also show a color-tilting effect, but are not opaque, so that the color-shift effect is also visible from the rear side of the security element.
  • the dielectric spacer layer is preferably produced by a vacuum vapor method.
  • the spacer layer can also be formed by a printing layer or by an ultrathin film, in particular a stretched polyester film.
  • Particularly preferred at present is a configuration in which the dielectric spacer layer is formed by a low-refractive dielectric layer, in particular a vapor-deposited SiCb layer or an MgF 2 layer. Further details on the structure of such thin-film elements and on the materials and layer thicknesses that can be used for the reflection layer, the dielectric spacer layer and the absorber layer can be found in the publication WO 01/03945, the disclosure of which is incorporated in the present application.
  • the absorber layer and / or the spacer layer can also have recesses in the form of patterns, characters or codes. There is no color shift effect in the recessed areas of the absorber layer or the spacer layer.
  • the security element additionally has a relief structure over which the thin-film element is arranged in an overlapping area.
  • the thin-film element may in this case be arranged partially or completely over the relief structure or may also project beyond it.
  • the relief structure may represent a diffractive structure, such as a hologram, a holographic grating image or a hologram-like diffraction structure, or an achromatic structure, such as a matt structure with a non-colored, silvery matt appearance, a micromirror arrangement, a blazed grating with a sawtooth-like furrow profile or a Fresnel lens arrangement.
