Definitions
- the invention relates to an optically variable security feature for documents, securities, banknotes, packaging and goods.
- optically variable security features are holograms, whose human-visually recognizable information is subject to change when viewed from different angles. This effect offered good copy protection, as the angle-dependent changes could not be imitated by a copier.
- Such holograms usually consist of a carrier film, a layer of curable lacquer into which diffractive structures are embossed, and a reflection and an additional protective layer.
- the reflection layer is embodied as a highly brilliant metallization which has been evaporated in a high vacuum and which, in order to test the authenticity, can additionally contain a functional design in the form of demetallized points which can be recognized by human vision or not recognized by human vision. These demetallized points can take the form of characters, letters or geometric figures.
- DE 40 30 493 shows that an optically variable element is applied to a multi-layer data carrier, in which additional information, such as a pattern for a functional design, which is subsequently introduced and can be recognized by human vision, is present and is superimposed on the optical effect.
- additional information such as a pattern for a functional design, which is subsequently introduced and can be recognized by human vision
- DE 39 32 505 describes data carriers with diffraction structures, the standard information of which can be changed in a human-visually recognizable manner by additional measures, for example by removing the metal layer.
- DE 44 19 089 and DE 44 19 173 have disclosed magnetizable luster pigments and luster pigment mixtures which are suitable for producing three-dimensional optical effects through the action of magnetic fields during or after their application in the still liquid application medium. They are based on multi-coated, platelet-shaped, non-ferromagnetic metallic substrates and are used in paints and printing inks. Among other things, they should be able to replace costly holograms, but the color change that can be achieved is still too low. Likewise, DE 195 15 988 describes that gloss pigments are used for coloring paints, inks and printing inks.
- DE 33 08 31 also shows that in the case of holograms, the metallic foil usually used as a reflection layer can also be produced by vacuum evaporation or by applying thin aluminum layers. Another possibility is the described casting process. When trying to remove the hologram from the security, the thin metal layers collapse and the hologram is subject to destruction.
- suitable polythiophenes for example 3,4-polyethylenedioxythiophene
- Another option for reading out the polythiophene markings is based on their electrical conductivity. With suitable electrode arrangements, the differences in surface resistance between the non-conductive support and the conductive markings can be registered.
- EP 753 623 to produce a security sheet which is used as.
- Counterfeit protection contains an electrically conductive element.
- the conductive element consists of a polythiophene polymer. Inks containing metal pigments are similarly called.
- DE 38 43 075 describes an arrangement in a security document with a security thread that contains a metallic coating.
- a layer with electrically conductive pigments or a layer made of an electrically conductive plastic due to its molecular structure is provided in the immediate vicinity of this coating. This layer serves to bridge any interruptions in the metallic coating of the security thread.
- the object of the invention is to provide an optically variable security feature with concealed, detectable features in order to increase counterfeit security, and despite their introduction, the manufacture should be able to be designed sufficiently quickly and inexpensively.
- the solution according to the invention affords the advantage of providing optically variable security features with concealed, detectable features that are not recognizable by human vision and can either be depicted pictorially or can be functionally supplemented by bridging interruptions to form a testable whole.
- optically variable security features with concealed, detectable features that are not recognizable by human vision and can either be depicted pictorially or can be functionally supplemented by bridging interruptions to form a testable whole.
- bridging interruptions to form a testable whole.
- 1 to 3 is a schematic representation of the different structure of an optically variable security feature, for example a hologram, consisting of a carrier film 1, a layer of PEDT / PSS (polyethylene dioxythiophene polystyrene sulfonate) 2, a curable lacquer layer 3, preferably as a carrier of diffractive structures, a reflection layer 4, a protective layer 7 and an adhesive layer 5.
- a carrier film 1 to 3 consisting of a carrier film 1, a layer of PEDT / PSS (polyethylene dioxythiophene polystyrene sulfonate) 2, a curable lacquer layer 3, preferably as a carrier of diffractive structures, a reflection layer 4, a protective layer 7 and an adhesive layer 5.
- PEDT / PSS polyethylene dioxythiophene polystyrene sulfonate
- the reflection layer 4 contains a functional design 6 in the form of interruptions.
- optically variable security feature The function of the optically variable security feature according to the invention is as follows: With the knowledge that the reflection layer 4 can contain a functional design 6 in the form of a microscript or other interruptions that are no longer recognizable by human vision, it is also possible for counterfeiters in a short time Introduce such a functional design 6 optically variable security feature. To increase the security against forgery, an electrically conductive feature substance in the form of a layer of PEDT / PSS 2 is applied to the carrier film 1 as a transparent, electrically conductive polymer. This layer from the PEDT / PSS 2 cannot be recognized by human vision and can only be detected by demonstrating its electrical conductivity.
- the layer of the PEDT / PSS 2 can form a functional design and is applied to the carrier film 1 as a coherent surface or as a surface divided by a line-like interruption. In the first case you can see the conductivity of the surface, in the second you check the electrical interruption of the otherwise electrically conductive surface.
- the layer from the PEDT / PSS 2 can, however, also be applied to the carrier film 1 as a line or as a plurality of straight or curved lines running side by side. In such a case, the pattern of the lines can be recognized with test equipment and evaluated if necessary. Similar to the lines, the layer from the PEDT / PSS 2 can also take the form of points.
- the conductivity of the layer PEDT / PSS 2 is adjustable either by the type of application or by the type of its special formulation.
- the reflection layer 4 contains the functional design 6 in the form of interruptions. These interruptions of the reflection layer 4, which are no longer visible in human vision, preferably follow the pictorial design of the diffractive structures of the hologram. This makes them more difficult to find.
- the functional design in the PEDT / PSS 2 and the functional design 6 of the reflection layer 4 are advantageously arranged in adjacent planes. In this case, parts of the functional design in the PEDT / PSS 2 and the functional design 6 of the reflection layer 4 interact in such a way that interruptions in the reflection layer 4 are bridged. In this way, despite the interruptions in the reflection layer 4, a coding that can be evaluated by machine is obtained. If the PEDT / PSS 2 and the reflection layer 4 are arranged in mutually separate planes, their design is advantageously designed such that they only produce a complete image together, which can be recognized with appropriate test equipment.
- the PEDT / PSS 2 shows significantly better properties than other organic conductors, such as the previously known polythiophenes as well as polypyrrole or polyaniline. It shows a higher transmission in visible light. It results in transparent, colorless to slightly blue colored coatings. Depending on the manufacturing conditions, minimal surface resistances can be achieved. It has better hydrolysis resistance, good light and temperature resistance, a high absorption in the range of 900 - 2000 nm and no absorption maximum in the range of visible light up to 800 nm. According to the invention, the PEDT / PSS 2 is applied in the form of an aqueous dispersion. This form of application fits into the technology of manufacturing security features such that there are no interruptions in the ongoing production process.
- the PEDT / PSS 2 is applied in its monomeric precursor to the intended positions of the optically variable security feature as a 3,4-ethylenedioxythiophene (EDT) and then with an oxidizing agent, namely iron III Toulol sulfonate solution in n-butanol, polymerized to PEDT / PSS 2.
- EDT 3,4-ethylenedioxythiophene
- an oxidizing agent namely iron III Toulol sulfonate solution in n-butanol
