Definitions

  • the invention relates to a security paper for producing documents of value, such as banknotes, passports, identification documents or the like, the security paper having at least two large-area security elements which are equipped with a visually verifiable, optically variable effect.
  • the invention further relates to a transfer element and a document of value with such a security element as well as a method for producing security paper and documents of value.
  • Valuable documents such as banknotes, shares, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other documents that are at risk of counterfeiting, such as passports or other identification documents, are equipped with various security elements to increase their security against counterfeiting.
  • “Security paper” is understood below to mean paper that serves as an intermediate product for further processing into valuable documents and can already be equipped with security elements such as watermarks, security thread, etc.
  • “Secure document” is understood to mean the finished product. B. the printed banknote or the individualized passport.
  • optically variable elements are understood to mean elements which show different optical effects depending on the viewing and illumination angle. Such optically variable elements are often used as security elements for documents of value, since on the one hand they can be checked visually in a simple manner without additional aids, and on the other hand a lot of effort is required to manufacture them and thus to imitate them.
  • Various types of security elements with optically variable elements are known.
  • a very simple, visually verifiable and very striking security feature are holograms that show different visual impressions, such as color impressions or information, from different viewing angles. Since the optically variable effect of the hologram cannot be reproduced by a color copier, these security elements offer very good protection against color copying.
  • security elements are known, the optical effect of which is generated by a layer containing optically variable pigments, such as, for. B. interference layer or liquid crystal pigments.
  • Thermochromic materials can also be used as a security feature for value documents.
  • "Thermochromism” is understood to mean the occurrence of reversible color changes of solids with changes in temperature. The reason for these color changes mainly lies in changes in the crystal structure.
  • a security thread with thermochromic properties is known from EP 0608 078 B1.
  • a plastic material is printed or with signs a thermochromic coating colored at normal temperature is placed over this imprint or these negative signs. When heated, the thermochromic coating becomes colorless so that the characters underneath become recognizable.
  • a thermochromic coating is described , which is colorless at normal temperature and becomes colored when heated so that the characters disappear.
  • thermochromic security threads have the disadvantage that they are very narrow and the thermochromic effect can only be seen in the relatively small window areas, which is why the optical effect caused by the color change of the thermochromic material is very inconspicuous. Such security elements therefore do not offer a high level of protection against counterfeiting.
  • Multi-layer thin-film elements can also be used as a security feature.
  • the color impression of the thin-film element changes with the viewing angle, for example from green to blue, from blue to magenta or from magenta to green. This color effect is based on interference effects due to multiple reflections in the various sub-layers of the thin-film element and is explained in detail, for example, in EP 0395410 B1.
  • the invention is therefore based on the object of providing a security paper with security elements which avoids the disadvantages of the prior art.
  • the counterfeit security of security security papers and value documents are improved while production is simplified.
  • the invention is based on the finding that the security against forgery of security papers and value documents can be improved by equipping the security papers and value documents with at least two large-area security elements which have an optically variable effect.
  • the present invention therefore relates to a security paper for the production of documents of value, such as banknotes, passports, identification documents or the like, the security paper having at least two large-area security elements with a visually verifiable, optically variable effect.
  • large-area security elements each with an optically variable effect, are combined with one another.
  • the large-scale processing makes it easier for a viewer to recognize and thus enables the authenticity of the value document to be checked reliably.
  • the term “large-area security elements” includes security elements that cover at least 1% of the area of the security paper or the value document.
  • the large-area security elements which cover at least 5%, particularly preferably at least 10%, in particular at least 20% and very particularly preferably at least 25% of the area of the security paper or of the value document.
  • the security elements make it easier for the user to check them. Since the authenticity check is carried out using the variable effects of the security elements, these must be easily recognizable. For this reason, large-area security elements are preferred which cover at least 1 cm 2 , particularly preferably 4 cm 2 , in particular 10 cm 2 and very particularly preferably 25 cm 2 of the area of the security paper or of the value document.
  • all known security elements with a variable optical effect can be applied to one another in any manner combined on a security paper.
  • security papers and security documents that are equipped with two security elements are described below, the number of security elements per security paper or security document is of course not limited to two. In principle, any number of security elements can be present on the security paper or the value document.
  • the security elements on a document preferably have different optical effects which may contrast with one another.
  • thermochromic substances are preferably used for the thermochromic layer, which are opaque below a predetermined temperature and at least translucent above this temperature. With certain Applications, it can be useful to use thermochromic substances that are translucent or transparent below a predetermined temperature and opaque above this temperature.
  • the transition temperature of the thermochromic substances is preferably above the ambient temperature, e.g. B. in the range of 25 ° C to 60 ° C, preferably 30 ° C to 60 ° C.
  • Multilayer thin-film elements are particularly preferably used as security elements.
  • the security elements can also contain optically variable pigments, in particular interference layer pigments, liquid crystal pigments or luminescent pigments.
  • security elements come into question which have a layer in which diffraction structures are present in the form of a relief structure.
  • holograms in particular embossed holograms, are preferably used as security elements.
  • security elements are also particularly preferred which have cutouts in the form of characters and / or patterns.
  • Equipping security elements with a so-called negative font leads to a further increase in security and better protection against counterfeiting.
  • This negative writing is e.g. formed by metal-free areas in an otherwise continuous metallic coating of the carrier material of the security element. Backlit, the element itself appears dark due to the opaque metallic coating. The metal-free areas stand out clearly against this dark background.
  • thermochromic and / or fluorescent layer can alternatively be arranged in the areas described above as “metal-free”.
  • security elements made of translucent or transparent materials can also be used. If two transparent security elements are applied, both of which have certain patterns, and if these security elements overlap at least partially, a moire effect results when superimposed, which is a visually easy to check and at the same time tamper-proof security feature.
  • a security element is preferably designed as a lens. If this security element is applied at least overlapping over a second security element, the second security element appears optically changed during visual inspection, such as. B. enlarged, reduced or distorted.
  • all security elements with a variable optical effect can also be equipped with feature substances, such as magnetic and / or conductive and / or luminescent substances. Counterfeit protection is further increased by such additional feature substances.
  • the security elements present on the security paper can be applied in any relative position to one another.
  • the security elements can be arranged on the front and / or back of the security paper. If the security elements are arranged next to each other, they can be visually checked separately.
  • the security elements can also be arranged overlapping. In this case, it is particularly preferred in the context of the present invention that the security elements are arranged in such a way that they complement one another to form a realistic or abstract image or a text. As a result, the recognizability for the viewer and at the same time the security against forgery are significantly improved.
  • a "picture” is generally understood to mean visually readable information. This includes both photorealistic representations and line motifs, ie abstract representations. Realistic representations include, for example, portraits, landscape motifs, animal motifs and buildings. Due to the increased image information, a photorealistic representation leads to one significantly improved identification and recognizability for the viewer, abstract representations are, for example, coats of arms, buildings, flags, patterns, characters and codes, all of which can be provided in perspective as well as in flat representation, as further examples May a text or individual letters or figures be mentioned, which, for example, by two overlapping security elements elements are formed. If security elements with different optically variable effects are used, usually only parts of the text or the figure can be recognized, while at a certain angle the two parts form the complete text or the complete figure. It is pointed out that the outline of the security elements can be chosen freely.

  • the individual security elements can also be arranged on the transfer element in any relative position to one another, that is to say next to one another or at least partially overlapping.
  • the security elements are preferably arranged such that they complement each other to form a realistic or abstract image or a text.
  • the security paper according to the invention is preferably equipped with the security elements after the paper production, the security elements being connected to the security paper in such a way that they cannot be removed again without destroying the security paper or the security elements.
