Definitions

• the invention relates to security elements with integrated matt structures, which are present as micro-typefaces in contrasting form to optically variable elements.
• Security elements are used in many areas to ensure the counterfeit security of sensitive goods.
• security features are used in data carriers, in particular value documents, such as identity cards, cards, banknotes, packaging materials for sensitive goods, such as pharmaceuticals, cosmetics, electronic components, labels, seals and the like, for example in the textile industry.
• Security elements with visually visible features are for example off EP - A 0 330 733 known.
• security elements in particular security threads consisting of a translucent plastic film, an over the entire security element extending opaque coating having recesses in the form of the coding to be introduced, in particular in the form of characters and patterns described.
• coloring and / or luminescent substances may be present at least in the regions defined by the recesses, by means of which the coding differs from the opaque coating under the corresponding influence of light in a color-contrasting form.
• the security elements may have diffraction structures or holograms, wherein the reflective metal layer present in reflection holograms is interrupted for the generation of transparently readable (transparent) recesses.
• the object of the invention is to provide a security element which has optically active elements and, in addition, elements which can be recognized in reflected light in the form of characters, elements, symbols, lines or the like.
• the invention therefore relates to security elements comprising a carrier substrate which is provided with optically active elements, in particular diffraction structures, diffraction gratings, surface reliefs or holograms, characterized in that the diffraction structure, the diffraction grating or the hologram achromatic matt structures in the form of characters, strings, patterns, Symbols, lines, or guilloches.
• optically active elements in particular diffraction structures, diffraction gratings, surface reliefs or holograms, characterized in that the diffraction structure, the diffraction grating or the hologram achromatic matt structures in the form of characters, strings, patterns, Symbols, lines, or guilloches.
• carrier foils are preferably flexible plastic foils, for example, 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, 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 or calendered, may 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 of natural, optionally treated fibers, such as viscose fibers used.
• the fabrics or nonwovens used have a basis weight of about 20 g / m 2 to 500 g / m 2 .
• the optically active structure is preferably introduced into an embossing lacquer applied to a carrier substrate.
• the embossing lacquer applied to the carrier substrate can be a radiation-curable lacquer, for example a UV-curable lacquer or a radiation-curable lacquer, or a volume-separated two-component embossing lacquer system.
• the embossing lacquer may be applied by known coating methods such as brushing, pouring, spraying, printing (screen, gravure, flexographic or digital printing) or roller coating.
• the optically active structure is introduced.
• a matt structure preferably in the form of so-called macro-characters having a size of less than 0.8 mm, or micro-characters having a size of less than 0.5 mm, preferably a size of less than 0.3 mm, is already introduced during the production of the optically active structure.
• Macros or micro-typefaces are understood to be characters, strings, patterns, symbols, lines or guilloches.
• the matt structures are already integrated in the generation of the diffraction structure in the master and are therefore inseparable and unalterable connected to the diffraction structure.
• the size of the characters and patterns is particularly advantageous with a size ⁇ 0.5 mm, since it takes up little space and thus hardly influences the appearance of the optically active structures.
• the matt structures are arranged in the form of guilloches or lines or raster images which may be in relation to or contrast with the optically active structures.
• lenticular or Fresnel lenses are used as the diffraction structures. These produce a particularly strong 3-dimensional effect, so that the matt structures on this background appear particularly rich in contrast and are even easier to see in reflected light.
• these are either coarsely or very finely embossed, so that no more diffraction takes place but only more light diffusion.
• the security element according to the invention can have further layers with functional or decorative properties.
• optical properties of a further layer can be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV region or in the IR region, effect pigments, such as liquid crystals, pearlescent, bronzes and / or Multilayer color change pigments and heat-sensitive colors or pigments influence. These are in all possible combinations used.
• phosphorescent pigments can also be used alone or in combination with other dyes and / or pigments.
• additional layers with electrically conductive and / or magnetic properties can also be present on the substrate, or can subsequently be applied.
• the security element according to the invention may be provided on one or both sides with a protective lacquer layer, which may optionally be pigmented.
• the security element according to the invention can optionally be laminated with one or more carrier substrates, which optionally have functional and / or decorative layers, using a laminating adhesive.
• 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, which adhesive or adhesive coatings can be pigmented.
• the security elements or the film material are therefore optionally suitable for packaging as security features in data carriers, in particular documents of value 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, 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, the width of the strips or threads preferably being 0.05-10 mm can and the patches preferably have average widths or lengths of 2-30 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 preferably average widths and lengths of 2- 30 mm.
• a corresponding security thread or strip can also be used as edge reinforcement of packaging, documents of value and the like in the region of the edges but also, for example, as longitudinal or transverse reinforcement in the packaging or in the document of value, whereby in each case several threads or strips are at a defined distance from one another can be provided.
