  • the invention relates to a grating image with achromatic grating areas.
  • the invention further relates to a method for producing such a grating image as well as a security element, a security paper and a data carrier with such a grating image.
  • holograms To protect the authenticity of credit cards, banknotes and other valuable documents, holograms, holographic lattice images or other hologram-like diffraction structures have been used for some years.
  • holographic diffraction structures are used in the banknote and security sector, which can be produced by embossing holographically generated lattice images in thermoplastically deformable plastics or UV-curable lacquers on film substrates.
  • Real holograms are formed by illuminating an object with coherent laser light and superposing the laser light scattered by the object with an uninfluenced reference beam in a photosensitive layer.
  • So-called holographic diffraction gratings are obtained when the light beams superimposed in the photosensitive layer consist of spatially extended, uniform, coherent wave fields.
  • the photosensitive layer for example a photographic film or a photoresist layer
  • a holographic diffraction grating which can be preserved in the form of light and dark lines in a photographic film or in the form of mountains and valleys in a photoresist layer.
  • holographic diffraction gratings can be formed by not covering the entire surface of the photosensitive material with a uniform holographic diffraction grating, but by using suitable masks to respectively cover only parts of the receiving surface with one of several different uniform lattice patterns occupy.
  • Such a holographic grating image is thus composed of several areas with different diffraction grating patterns, which are usually adjacent to each other in a flat, strip-shaped or pixel-like design. By suitable arrangement of the areas can be with such a holographic lattice image
  • the diffraction grating patterns can be produced not only by direct or indirect optical superposition of coherent laser beams but also by electron lithography. Frequently, a pattern diffraction structure is generated, which is then converted into a relief structure. This relief structure can be used as a stamping tool.
  • WO2005 / 071444 A2 describes grating fields with grating lines which are characterized by the parameters orientation, curvature, spacing and profiling, at least one of which varies the parameter over the surface of the grating field. If one of the parameters varies randomly, we speak of so-called matt structures. These show when viewed no diffractive effects, but scattering effects and have a dull, preferably no color showy appearance. The matt structures show the same appearance with pure scattering effects from all viewing angles.
  • the present invention seeks to further improve lattice images of the type mentioned, and in particular under Maintaining the previous advantages grid images with new optical effects to create and / or to further increase the anti-counterfeiting of the lattice images.
  • the grating image comprises achromatic grating regions which have a viewing angle-dependent appearance, resulting in a visually apparent moving effect as the viewing angle changes, in which the achromatic grating regions apparently move on a trajectory with a particular direction and velocity.
  • the achromatic grating areas have a matt - preferably silvery matte - non-colored appearance, which changes depending on the viewing angle. It could also be said that the achromatic grating areas are matt structures, but - in contrast to the prior art - have a viewing angle-dependent appearance.
  • the change may consist in the change of the optical brightness or else consist in a grating area being visible under a certain viewing angle and not being visible at a different viewing angle.
  • the respective achromatic grating region of the grating image contains a grating pattern influencing electromagnetic radiation with grating lines, which are characterized by the parameters orientation, curvature, spacing and profiling and for which at least the parameter orientation over the area of the grating area randomly, preferably randomly varies in a sudden jump in a limited angular range.
  • said grating region contains a grating pattern influencing electromagnetic radiation from uninterrupted grating lines.
  • Diffraction understood the deviation from the rectilinear propagation of the light, which is not caused by refraction, reflection or scattering, but which occurs when light hits obstacles such as columns, apertures, edges or the like. Diffraction is a typical wave phenomenon and therefore strongly wavelength dependent and always associated with interference. It is to be distinguished in particular from the processes of reflection and refraction, which can be accurately described with the image of geometric light rays. Did you have it with diffraction at very many To do this with statistically distributed objects, it has become customary to speak of scattering instead of diffraction on irregularly distributed objects.
  • Scattering refers to the deflection of part of a bundled wave radiation from its original direction when passing through matter due to interaction with one or more scattering centers.
  • Scattering of light on objects with a size in the range of the light wavelength and below is also usually wavelength-dependent, such as the Rayleigh scattering or the Mie scattering. From an object size exceeding ten times the wavelength, one usually speaks of non-selective scattering in which all wavelengths are affected approximately equally.
  • non-selective scattering can also be achieved with smaller objects if the objects have only an irregular distribution and a suitable bandwidth of object sizes, since then the wavelength-dependent properties of the individual objects are found out over the entire ensemble.
  • a random, in particular a random and erratic variation of the orientation in a restricted angular range is understood to mean the following.
  • the orientation of the grid lines in a grid pattern influencing electromagnetic radiation can theoretically extend over an angular range of +/- 90 ° in a Cartesian coordinate system.
  • the angle that determines the orientation is the acute angle between the x-axis and the observed grid line. Do all grid lines have the same orientation? - So the same angle in the coordinate system - on, the lines are parallel and it is a pure diffraction grating. If the grid lines are completely randomly oriented over the entire angular range, all grid lines are randomly distributed and no preferred orientation can be determined.
  • the grid pattern shows pure scattering effects and thus no viewing angle dependent effects. Such lattice patterns are called matt structures. If the orientation varies randomly, but within a limited angular range, ie within an angle range within the specified limits of + 90 ° and - 90 °, the grid pattern shows a certain regularity. The grid pattern shows a more or less strong preference orientation so that the observer perceives the grid pattern differently depending on his viewing angle.
