Definitions
- the invention relates to security elements with machine-readable features that ensure increased security against counterfeiting.
- Security elements in the form of threads, strips, tapes, patches or other formats are used primarily in value documents, for example banknotes, identity papers and the like. Most of these security elements have combined features, such as optical features and / or conductive features and / or magnetic features.
- Object of the invention was to provide security elements that have visually unrecognizable machine-readable features and ensure increased security against counterfeiting.
- the invention therefore relates to security elements comprising a carrier substrate to which one or more functional security features are applied, characterized in that the carrier substrate has full-area or partial printing from an X-ray-absorbing coating which is covered by a cover layer.
- Another object of the invention is a film material consisting of a carrier substrate on which one or more functional security features are applied, characterized in that the carrier substrate has a full-area or partial printing from a X-ray absorbing coating, which is covered by a cover layer has.
- Carrier substrates are, for example, carrier films, preferably flexible transparent plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC 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, may also serve as the carrier substrate.
- the films can also be surface-treated, coated or laminated, for example, with plastics or painted.
- carrier substrates also paper or composites with paper, for example, composites with plastics with a basis weight of 20 - 500 g / m 2, preferably 40 - 2 are used 200 g / m.
- woven or nonwovens such as continuous fiber webs, staple fiber webs and the like, which may optionally be needled and / or calendered, can be used as the carrier substrates.
- fabrics or webs of plastics such as PP, PET, PA, PPS and the like, but it can also be woven or nonwovens made of natural, optionally treated fibers, such as viscose fibers are used.
- the nonwovens or fabrics used have a weight per unit area of about 20 g / m 2 to 500 g / m 2 . If necessary, the nonwovens or fabrics must be surface-treated.
- the carrier substrate is printed over the entire surface or partially with an ink which is heavily pigmented with heavy elements.
- the pigment content may be 25-85% by weight, preferably 50-85% by weight.
- Suitable pigments include TiO 2 , BaSO 4 , phthalocyanines, Cu porphyrins, Cr compounds, CdSO 4 or other heavy metal compounds.
- This layer can be effected by known printing methods (gravure printing, flexographic printing, screen printing, offset printing, digital printing and the like).
- the application of the partial layer can take place in the form of signs and patterns, flat or linear, wavy or zigzag-shaped and similar or analogous structures, such as guilloches, along and / or transversely to the machine direction of the substrate.
- a thin metallic layer is applied to cover the printing.
- this layer can be applied over the entire surface or partially at least in the areas covering the printing.
- the cover layer may be present on one or both sides of the carrier substrate.
- metallic layers for example, metallic layers such as Al, Cu, CO, Fe, Cr, Ti, Ni come into question.
- the thickness of the metallic layer is chosen so that the X-ray radiation can penetrate unhindered through this layer.
- the thickness of the metallic layer is preferably about 10 to 50 nm, preferably 15-25 nm.
- the deposition of the metallic layer may be accomplished in any known conventional manner, for example by (partial) spin-coating, brushing, vapor deposition, by printing (gravure, flexo, screen, offset, digital, and the like) by spraying, sputtering, or roller coating techniques Partial execution, for example, by known demetallization using an etchant or preferably a soluble wash.
- the printed X-ray sensitive layer can also be covered by laminating with opaque materials, for example with metallized or with printed or opaque films.
- the areas printed with the highly pigmented ink absorb this radiation, these areas then appear bright on the X-ray image (white).
- the security elements or film materials may also be provided on one or both sides with one or different coloring layer (s).
- the design of the non-all-colored coloring layer can represent an additional security feature or authenticity feature or identification feature.
- the security elements or film materials may have, in addition to one of the layers described, an optically active structure, for example a surface relief, a diffraction grating or a hologram, which structures may serve as an additional security feature, authenticity or identification feature.
- an optically active structure for example a surface relief, a diffraction grating or a hologram, which structures may serve as an additional security feature, authenticity or identification feature.
- the optically active structures can be prepared in any known manner. However, these diffraction-effective structures are preferably obtained by coating the carrier substrate, which optionally already has one or more of the described layers, with a radiation-curable lacquer which is pre-cured to the gel point by excitation with radiation of a defined wavelength, and simultaneous impression of the surface structure, whereupon the further Curing (main hardening) of the radiation-curable varnish by excitation radiation performed a different wavelength to the pre-curing step, followed, if necessary, a post-curing.
- the security elements according to the invention can be provided with a protective lacquer layer on one or both sides.
- the protective lacquer may be pigmented or unpigmented.
- the security element according to the invention can be provided on one or both sides with a hot or cold seal adhesive or a self-adhesive coating for application to or for embedding in a substrate.
- the security elements or the film material may therefore be suitable as security features in data carriers, in particular value documents such as identity cards, cards, banknotes or labels, seals and the like, but also as packaging material, for example in the pharmaceutical, electronics and / or food industry, after appropriate packaging.
- packaging material for example in the pharmaceutical, electronics and / or food industry, after appropriate packaging.
- blister sheets, cartons, covers, film packaging and the like for example, in the form blister sheets, cartons, covers, film packaging and the like.
- the substrates or film materials are preferably cut into strips or threads or patches, wherein the width of the strips or threads may preferably be 0.05-10 mm and the patches preferably have average widths or lengths of 0.3. 20 mm.
- the film material is preferably cut into strips, tapes, threads or patches, wherein the width of the threads, strips or tapes is preferably 0.05-50 mm and the patches are preferably average widths and lengths of 0, 5-200 mm.
- a corresponding security thread or strip can also be used as edge reinforcement of packaging, value documents and the like in the region of the edges but also as, for example, longitudinal or transverse reinforcement in the packaging or in the value document. wherein in each case a plurality of threads or strips can be provided at a defined distance from each other.
