Definitions

• the invention relates to a tactile tactile security element, in particular for value documents.
• security elements are known which are embedded in the value document, usually in the form of a security thread, wherein this security thread can have different visually and / or machine-recognizable features.
• security elements for application to value documents are known which have visually recognizable properties, for example optical or optically active features.
• WO 20061106156 A2 For example, a security paper having expandable security elements embedded in the paper and expanding by heat and pressure during the manufacturing process or in a subsequent process and then forming a dome continuous relief on the paper surface is known.
• a security element is known which is produced by an expandable printing ink and its treatment with a laser and forms a relief on the surface in accordance with the printing.
• a value document with a security feature in which the surface of the value document is marked by means of laser radiation in such a way that fibers protrude tangibly out of the surface.
• Tactile tactile security elements are particularly desirable for better distinguishability of value documents of different value for visually impaired people.
• the object of the invention was to provide a tactile security element which, in addition to further security features on the value document, increases the security against counterfeiting.
• the subject of the invention is therefore a value document with at least one security element, characterized in that the security element consists of a primary and a secondary security feature, the secondary security feature at least partially superimposed on the primary security feature and makes this tactile recognizable.
• value documents are essentially understood banknotes, securities, identity cards, tickets and the like.
• the primary security feature is preferably an optically recognizable security feature.
• Optically recognizable security features include, for example, optically active security features such as holograms, diffraction structures, diffraction gratings and the like, or security features which show a different visual appearance from different viewing angles, for example security features with color change.
• These security elements can, for example, according to EP 1 318 016 A1 or EP 1 558 449 A1 getting produced.
• the tactile element (secondary security feature) is created.
• a perforated film can be applied to the security element.
• a film for the secondary security element for example, preferably flexible plastic films, for example, from PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC, fluoropolymers such as PTFE and the like in question.
• the carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
• metal foils for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 ⁇ m, preferably 10 to 80 ⁇ m, particularly preferably 20-50 ⁇ m.
• the perforations may have different shapes and dimensions and be spatially arranged in different ways.
• the perforations may, for example, be round, oval, angular, star-shaped, in the form of bars, crosses and the like.
• the perforations can be arranged at the same or different distances from one another but also in the form of a pattern or sign or a symbol.
• the perforations can be made in a known manner, for example, by punching, cutting, lasering, firing or local evaporation.
• the tactile secondary security feature may also be provided by printing on the primary security feature with UV inks, which are then cured by UV radiation, take place.
• the printing can be done in the form of patterns, characters, symbols and the like.
• the printing is carried out by screen printing in order to achieve a sufficient layer thickness.
• the security element described is applied in known manner to the value document by transfer application or by lamination or gluing. However, it can also be partially embedded in a value document, wherein the tactile security element is arranged in a window of the security.
