Definitions

  • Valuable and security product with luminescent security elements and method for manufacturing the same and arrangement for visual and mechanical authenticity checking.
  • the present invention relates to security documents with graphically, preferably in gravure, security features which can be illuminated in the form of dots, lines and / or planes, with wavelengths in the invisible UV range to the range visible to the human eye from typically 360 to 780 nm but also in the infrared range.
  • DE 43 10 082 A1 presents electroluminescent films which are produced from inorganic (s), electroluminescent (s) pigment (s) and thermoplastic by means of extrusion or coextrusion. Basically, the extrusion or co-extrusion of such a system on security papers would be conceivable, but the graphic design options appear to be limited by the process logistics and the entire manufacturing process for the production of a security document and the necessary ones
  • DE 43 15 244 AI describes a method for producing an electroluminescent film using the sputtering technique. This method would also be fundamentally conceivable for the production of security documents, but such a production method represents an extremely high outlay with regard to the vacuum chambers required for this technology and is furthermore very difficult to integrate into a possible production process and also produces film layers by means of additional special Coatings for the high mechanical requirements of security documents would have to be equipped.
  • Security element (security thread) presented, which is * multilayered and has electroluminescent properties.
  • the disadvantage of this arrangement is that a relatively high surface area has to be accepted, because the electrodes required to excite the EL substances are arranged one above the other.
  • the invention is therefore based on DE 41 26 051 AI the task of developing a value and security product so that the El-active security features cause a much thinner layer structure on the surface of the security document.
  • the advantage of the invention is therefore that the formation of a multilayer EL system arranged one above the other is dispensed with.
  • this relatively thick construction is dispensed with in that the electric field is built up laterally, that is to say flatly becomes.
  • a transparent, electrically conductive layer is required which is achieved by means of so-called ITO pastes (indium tin oxides). The same is also achieved by pre-coated transparent films or glasses.
  • ITO indium tin oxide
  • High-quality EL systems require a uniform luminance and maximum luminous efficiency. Due to the high thermal resilience in coating processes, glass substrates generally offer a higher quality solution with higher light transmittance in the visible wavelength range and at the same time better surface conductivity.
  • the main advantage of the ITO pastes printing technology used according to the invention lies in the relatively simple application and the almost arbitrary graphic design options, which can be advantageous in particular in more complex systems with regard to the electrical connections.
  • bus bars which are electrically conductive borders
  • the connection of the ITO electrode can be made functionally favorable with this technique and ultimately the ITO electrode layer thickness can be reduced to a minimum in favor of a higher transparency in the thickness.
  • bus bars are printed using printing technology using silver, carbon, copper, etc. pastes, or a combination of these elements, and surface resistance values in the range of a few 10 milli-ohms / square values are achieved.
  • Excitation via an alternating electromagnetic field 6.
  • Excitation through a system based on the photoluminescence excitation via appropriate light sources, in particular in the UV wavelength range and the use of suitable luminescent substances based mainly on silicates activated with Mn , Phosphates, tungstates, germanates, borates, etc., but in particular based on Zn2Si04: Mn and the excitation by the 253, 65 nm line of a Hg low-pressure discharge lamp (visible light by means of
  • the excitation by IR radiation with a suitable wavelength is provided instead for materials with specific IR absorption and emission in the visible range.
  • OVI pigments optical variable pigments
  • liquid crystals can also be used or added to the El pigments.
  • the valuable and security product has security elements based on so-called microencapsulated inorganic compounds of groups II and VI of the periodic table (eg, ZnS, CdS) which are doped or activated with metals such as Cu, Mn, Ag and for which Printing technology design by gravure are suitable.
  • Electroluminescent security elements based on organic polymers can also be constructed.
  • the electrodes are formed laterally (i.e. lying flat next to one another) by means of conductive intaglio printing inks, an alternating electromagnetic field being generated in the resulting, also approximately flat field gap between the electrodes, the field lines of which at least partially penetrate the printed image produced by the EL substances and thereby make the electroluminescent security elements shine and they can thus be used visually and mechanically for the authenticity check.
  • an electrically conductive gravure printing ink based on carbon and / or silver or a mixture of both or silver-plated and / or gold-plated metallic pigments or mica pigments are used in conjunction with suitable binders based on polyurethanes and / or aliphatic polyesters and corresponding diluents, the two electrode connections in particular being designed in a non-oxidizing surface shape.
  • an aqueous polyurethane layer is preferably applied to the unprepared surface of the security document - preferably a bank note - before the actual graphic design and then the phosphor paste is printed in order to achieve a good and elastic adhesive bond with excellent surface resistance.
  • the luminescent security feature is preferably designed graphically from individual points and lines.
  • a method for producing the security document comprises the following process steps:
  • an adhesion promoter in the form of an aqueous polyurethane dispersion for the optimal connection and embedding of the following printing layers - printing the lateral electrodes using conductive pastes and, depending on the system, repeating this process several times to achieve a surface resistance that has a sufficient power supply or a sufficiently low surface resistance for the selected geometry of the security elements, - printing an insulation color, in particular with the property of high elasticity, good bond to the substrate, for the conductive coating and for the subsequent phosphor color , and also with a dielectric constant as high as possible, in particular aqueous polyurethane dispersion systems and / or filled with barium titanate (BaTi03) being used to increase the dielectric constant,
  • a kind of thermal pressing can be used to stabilize and improve the quality of the security document at temperatures up to 200 ° C and pressures up to 50 kp / cm 2 .
  • the invention therefore includes, inter alia, that laterally arranged electrodes by means of electrically conductive intaglio inks or pastes are arranged in such a way that geometries are possible according to the extremely high resolution or fineness of the printed image using intaglio printing technology, which enables high electric field strengths and thus the electroluminescence excitation of typical zinc sulfide phosphor layers.
  • the gravure printing technique proposed according to the invention represents a very favorable solution for the present invention due to the extremely high possible resolution and the layer thickness which is nevertheless several micrometers thick.
  • the design of the various gravure printing inks or pastes requires special adjustment to significantly smaller pigment diameters compared to screen printing inks.
  • Essential to the invention is the use of microencapsulated elements with EL phosphor paste in rotogravure and capsule diameters with a few micro-meters (e.g. in the range from 0.2 to 40 micro-meters) are used.
  • Substances for fluorescent tubes Such substances are excited by the 253, 65 nm line of a Hg low-pressure discharge lamp (visible light eliminated by means of a short pass filter) and the emission of light takes place in the visible green range.
  • laser light sources are used for photoluminescence excitation, which excite UV light emission, which are then caused to emit visible light by means of conventional phosphors.
  • 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 the electromagnetic 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.
