Definitions

  • the present invention relates to Security documents with graphic, preferably in gravure printing, designed security features, the dot, dash and / or Can be lit in a flat shape, whereby Wavelengths in the invisible UV range up to the Human eye visible range from typically 360 to 780 nm but also aimed and realized in the infrared range become.
  • the invention is therefore based on DE 41 26 051 A1 based on the task of a product of value and security to further develop that the El-active safety features much thinner layer structure on the surface of the Effect security document.
  • the advantage of the invention is therefore that the formation of a multi-layered, flat EL system is waived.
  • an EL plate capacitor structure according to the invention in which the capacitor "plates” in lying side by side on essentially the same level are formed and in the field gap in between Necessary field is generated becomes a transparent, electrically conductive layer required by means of so-called ITO pastes (indium tin oxides) is achieved.
  • ITO pastes indium tin oxides
  • polyester films with vapor deposition or sputter-coated, electrically conductive Tin oxide, indium tin oxide (ITO), or in general transparent electrically conductive metallized surfaces with surface resistance values in the range of a few ohms / square for glass substrates and typically 20 ohms / square up to 300 Ohms / square and above.
  • ITO indium tin oxide
  • High quality EL systems require a uniform Luminance and maximum luminous efficiency.
  • glass substrates offer due to the high thermal resilience Coating processes i.a. a higher quality solution with higher light transmission in the visible wavelength range with better surface conductivity.
  • Coating processes i.a. a higher quality solution with higher light transmission in the visible wavelength range with better surface conductivity.
  • the essential Advantage of the ITO pastes used according to the invention printing technology lies in the relatively simple application and almost any graphic design option, which is particularly important in the case of more complex systems electrical connections can be advantageous.
  • bus bars are electrically conductive borders used. Thereby uniform electrical fields are achieved and thus a uniform luminance. Furthermore, with this technique the Connection of the ITO electrode can be designed to be functionally favorable and ultimately the ITO electrode layer thickness in favor of greater transparency in thickness Minimum be reduced. According to the invention, bus bars are in Printing technology using silver, carbon, copper, etc. pastes printed, or a combination of these elements and thereby Surface resistance values in the range of a few 10 mOhm / square Values reached.
  • the value and Security product Security elements based on so-called Group II and microencapsulated inorganic compounds VI of the periodic table (e.g. ZnS, CdS) based on metals such as Cu, Mn, Ag are doped or activated and for which Printing technology design by gravure are suitable. It can also use electroluminescent security elements on the Based on organic polymers.
  • the electrodes are lateral using conductive gravure inks (ie lying flat next to each other), where in the resulting, also arranged approximately flat Field gap between the electrodes an alternating electrical field is generated, the field lines of which at least partially by penetrate the printed matter generated by EL substances and thereby make the electroluminescent security elements glow and this visually and mechanically for authenticity checking can be used.
  • it becomes a electrically conductive gravure ink based on carbon and / or silver or a mixture of both or silver-plated and / or gold-plated metallic pigments or Mica pigments in combination with suitable binders Based on polyurethanes and / or aliphatic polyester and appropriate diluents used, in particular the two electrode connections in a non-oxidizing Surface shape are executed.
  • A is preferably used as the dielectric and insulation layer aqueous polyurethane layer on the unprepared surface of the security document - preferably a bank note - before the actual graphic design and then applied the EL paste is printed the better and more elastic Adhesive bond with excellent surface resistance too to reach.
  • the luminescent security feature is here preferably designed graphically from individual points and lines.
  • the invention is in a preferred embodiment according to the description above, among other things in that for the first time laterally arranged electrodes by means of electrically conductive gravure inks or pastes like this be arranged that according to the extremely high resolution or Fineness of the printed image using gravure printing geometries be possible, the high electrical field strengths and thus the Electroluminescence excitation of typical zinc sulfide Phosphor layers enables.
  • certain EL substances can be covered by UV filter layers in the form of printing inks, for example pigments filled with TiO 2 , so that the EL substances are not excited by UV light, but only by excitation in an electrical field. This is particularly recommended for the machine check of the security document with the test device according to the invention, in which - in a preferred embodiment - visible light is no longer used for the check.
  • a value and Security product 1 described in the form of a banknote although the invention is not so limited.
  • the value and Security product 1 in Figures 1 to 13 is therefore in essentially from a paper which - in the shown Exemplary embodiment - consists of cotton fibers.
  • a first embodiment now provides that the El-active substances 5 on the embossing base 4 are applied outside the intaglio printing ink 2.
  • the depth the embossing is with such a value and Security product 1 with about 1-80 microns, the Height of the intaglio ink surcharge on the paper corresponding to approx. 20% of the depth of the embossing, i.e. approx. 1 to 20 microns.
  • the distance 6 is therefore about 1 to 80 microns.
  • FIG. 2 shows the enlarged representation of FIG. 1, it can be seen that the El substances 5 outside the Gravure area are arranged.
  • Figure 3 is in a modified embodiment shown that the El substances 5 also below the Intaglio printing ink 2 arranged in the area of the elevations 3 can be and therefore of intaglio printing ink 2 are covered.
  • Figure 3 shows that the El substances in a Surface coating 7 of the security document 1 protrude or - as shown in Figure 4, on the Surface coating 7 and below the intaglio printing ink 2 are arranged.
  • Figure 5 shows as a further embodiment that this El-active substances 5 from microcapsules 8 in the Intaglio printing ink 2 are mixed in and with this are printed.
  • Figures 8 and 9 further show that the El-effective Substances in pigment form in intaglio printing ink 2 are mixed in and used here a binder 11 becomes.
  • luminous colors 12 can also be used be added to the light emission of the El substances with the luminous colors 12 used here to one characteristic lighting of the security features 9 to bring.
  • Figures 10 and 11 show that in addition to the use of Luminous colors also used translucent printing inks 13, 14 different colors, e.g. green and red inks, printed in separate places can be made to light up in a single color El substances a different, visually visible To give coloring.
  • Luminous colors also used translucent printing inks 13, 14 different colors, e.g. green and red inks, printed in separate places can be made to light up in a single color El substances a different, visually visible To give coloring.
  • the colors mentioned can also be used a translucent printing ink with the addition of a UV filter are covered, or the translucent colors 13, 14 can also be applied under the El layer.
  • Electrode arrangement 19 consisting of two electrodes 24, 25, are arranged on the surface of the security document 1, the two electrodes 24, 25 as flat elements are arranged side by side (laterally) and between a zigzag-shaped, insulating field gap 26 train in the area of said electrical Alternating field is generated, which excites the El substances 5 is needed.
  • the two electrodes 24, 25 at least partially from an insulating printing ink 17 covered, and the two electrodes 24, 25 are through generates conductive printing inks 16, on which corresponding Contacts 18 are seated, one on contacts 18 AC voltage is applied. This is shown in Figure 13 where it can be seen that at the connections 20 the said AC voltage is applied.
  • the El-active substance 5 is in the intaglio ink 2 embedded and is at least partially above the Field gap 26 so that the field lines generated in the field gap 26 the security feature arranged on the field gap 26 enforce it and make it light up.
