Definitions

  • the invention relates to a document of value, a security element and a security paper with a machine-readable authenticity indicator.
  • the invention also relates to various methods for checking the authenticity of such value documents, a security element or a security paper.
  • Valuable documents such as banknotes, shares, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other documents that are susceptible to counterfeiting, such as passports or other identification documents, are generally provided with various security features to increase counterfeit security.
  • infrared detectors are used, which are sensitive in the wavelength range from 780 nm to 800 nm and with which the infrared absorption of the security code can be detected.
  • Such infrared detectors are now commercially available and widely used.
  • the protection against counterfeiting by the security coding described can therefore no longer be rated as particularly high, since the part of the coding which is invisible to the human eye can also be detected by anyone without any particular effort. This gives rise to starting points for unauthorized imitations or readjustments of the security code of EP 0340898 A2.
  • a security feature is machine-readable, since an automatic authenticity check of a large number of documents of value can then be carried out in a short time, for example in a banknote processing machine.
  • an inconspicuous or invisible inspection of a document or a protected object is often sought, which can usually only be carried out with the aid of a machine-readable security feature.
  • the present invention is based on the object of specifying an authenticity indicator for documents of value and other objects to be secured, which avoids the disadvantages of the prior art and ensures increased security against forgery.
  • the authenticity mark should be machine-readable.
  • a security element for securing an object a security paper for the manufacture of security or Documents of value, methods for checking the authenticity of the objects mentioned and a device for carrying out the authenticity test are the subject of the subordinate claims. Developments of the invention are the subject of claims under.
  • the authenticity mark comprises a luminescent marking substance and a marking substance absorbing in the infrared spectral range. It has been found that when only one marking substance is used, it is relatively easy to analyze and imitate the authenticity mark, since only one property of the marking substance always has to be recognized and imitated. If, on the other hand, several substances are combined that have the same or very similar effects, for example different fluorescence, the two properties can influence each other during the detection, so that successful detection can no longer be guaranteed in all cases.
  • the marking substances do not interfere in the combination according to the invention, since different substance properties are queried during the detection. Furthermore, the infrared-absorbing marking substance does not provide an active signal for the analysis of the substances contained, so that the analysis is made significantly more difficult for the counterfeiter.
  • the analysis or re-enactment of luminescent marking substances is comparatively simple, since the radiation emitted can easily be made visible by irradiation of a wide spectral range.
  • the interaction of the two material properties is used as the basis for used the evaluation of the authenticity check.
  • the effects of the interaction between the two marking substances cannot be easily reproduced and therefore offer particularly high security against forgery.
  • the luminescent marking substance emits in the infrared spectral range, preferably at a wavelength ⁇ above approximately 1100 nm, particularly preferably above approximately 1200 nm.
  • This has the advantage that the luminescence is then not possible with conventional and easily available infrared detectors, which are mainly sensitive in the wavelength range from 780 to 800 nm, can be detected. Due to the bandgap of silicon of 1.12 eV, conventional silicon photodiodes do not allow detection of infrared radiation with wavelengths above about 1100 nm. Detectors for longer-wave infrared radiation are much more complex and are not available to everyone.
  • the luminescent marking substance emits in the absorption region of the infrared-absorbing marking substance. This allows the interaction effects of the two marking substances already mentioned to be exploited.
  • the luminescent marking substance is advantageously also excited in the infrared spectral range, preferably in the spectral range from approximately 800 nm to approximately 1000 nm.
  • the infrared-absorbing marking substance is essentially colorless in the visible spectral range or has only a weak intrinsic color. It is then invisible under normal lighting conditions or appears little striking.
  • the infrared-absorbing marking substance can be transparent in the visible. Even at a wavelength of approximately 800 nm, the infrared-absorbing marking substance advantageously does not yet have any significant absorption in order to avoid detection by commercially available infrared detectors.
  • the infrared-absorbing marking substance preferably exhibits significant absorption only in the spectral range between approximately 1200 nm and approximately 2500 nm, preferably in the spectral range between approximately 1500 nm and approximately 2000 nm.
  • the infrared absorption of the authenticity mark is then not detectable at the wavelengths of conventional infrared detectors, but only appears in the longer-wavelength and more difficult to access spectral range above 1200 nm and above 1500 nm.
  • Preferred infrared-absorbing markers have less than about 40%, in particular less than about 25% of the absorption in the visible spectral range in the range from 1200 nm to 2500 nm or in the range from 1500 nm to 2000 nm, based in each case on the area below Absorption curve for the respective spectral range.
  • infrared-absorbing marking substances are used, for example, substances based on doped semiconductor materials.
  • Substances containing metal oxide are also suitable. These are characterized in particular by their resistance to aging.
  • the infrared-absorbing marking substance is preferably in particle form with an average particle size of less than 50 ⁇ m. As a result, visible light is only slightly scattered by the particles, so that the marking substance is colorless or has only a weak intrinsic color.
  • Examples of infrared absorbers which have no appreciable absorption either in the visible or at about 800 nm are about 2,5-cyclohexadiene-1,4-diylidenes ⁇ is [N / N-bis (4-dibutylaminophenyl) ammonium] bis ( hexafluoroantimonate) with the formula C62H92N6Fi2Sb2, or the dyes ADS 990 MC with the formula 032H 3 ON 2 S 4 Ni, or ADS 1120P with the formula C52H44 CfeO ⁇ from Siber Hegner GmbH, Hamburg.
  • the luminescent marking substance can be formed on the basis of a host lattice doped with a side earth metal. Examples of such luminescent marking substances are contained, for example, in the publication WO 99/38701, the disclosure of which is included in the present application.
  • the luminescent marking substance and the infrared-absorbing marking substance are formed by separate substances which are inserted into the value document or onto which the value document is applied separately. This allows great flexibility in the selection of the two marking substances in order to be able to meet different and sometimes contradicting requirements, for example with regard to safety, durability, wear resistance and manufacturing costs.
  • the luminescent marking substance and the infrared-absorbing marking substance are introduced together as a mixture of substances into the value document or applied to the value document.
  • This variant also offers significant advantages because the mixture of substances can be applied in a single pass. This results, for example, in the printing of banknotes with significantly fewer restrictions Banknote design than when using two separately applied marking materials. In the latter case, it is often necessary to dispense with a visible printing process or an expensive additional printing process is carried out on another printing unit.
  • the luminescent marking substance to a large-area, invisible, infrared-absorbing feature, such as a barcode, a uniform and high area coverage of up to about 50% can be achieved.
  • the detection of luminescent markers in the conventional admixture with visible printing ink is often impaired by the colored pigments of the color.
  • the distribution of the marking substance is also very inconsistent due to the different printed images for banknotes with different denominations.
  • a test step can be omitted in quality control of the invisible print.
  • checking the print quality of the bar codes ensures that the correct line width of the color is printed.
  • the quality control of the admixed luminescent marking can then be limited to the incoming control of the color.
  • the luminescent marking substance is introduced over the entire surface into the value document or applied, for example printed, onto the value document.
  • the luminescent marking substance then provides a uniform background for an absorption or emission measurement, which can be used, for example, as a constant reference signal in an authenticity check.

  • the methods are particularly suitable for marking security paper which is used for the production of security or value documents, such as bank notes, identity cards or the like.
  • the luminescent marking substance can be added to a coating slip or applied together with a surface sizing to the surface of a value document or to the substrate materials used for its production.
  • films are also particularly suitable for producing documents of value into which the luminescent marking substance can also be introduced, for example by coextrusion.
  • the infrared-absorbing marking substance is preferably applied to the value document, in particular it is printed on the value document. All suitable printing methods can be used for printing. Ink-jet printing is particularly preferred since curved surfaces can also be printed in a simple manner an individualization of the print for different objects is easily possible.
