Definitions

  • the present invention is aimed at a method for producing a multi-layer value document substrate, which is designed to be particularly forgery-proof. Furthermore, the present invention is directed to a device for producing the multi-layer value-document substrate and to the value-document substrate itself.
  • EP 2 660 067 A1 shows a document of value with a flat substrate, at least one security element on a surface of the flat substrate and with protective layers.
  • an authenticity check of a banknote also depends on whether the design or the arrangement of the individual components is as intended by an authorized manufacturer.
  • the value document substrate has a first layer on which an optical element is arranged.
  • An opaque second layer extends over the first layer and has a continuous opening in the region of the optical element.
  • the document WO 2011/138007 A1 discloses a banknote with an opaque polymer substrate.
  • the opaque polymer substrate has a motif area whose transmittance is changed by means of openings.
  • a security document having a substrate of transparent plastic material. Opacifying layers are arranged on both sides of the transparent substrate, each of which has a recess in one area in order to form a transparent surface or window in the security document. A safety device is provided in the window. A protective coating may be applied over the security device in the window.
  • a security document with a transparent substrate is known.
  • a security element is arranged on one side of the transparent substrate.
  • an opaque layer is applied to the transparent substrate, with the opaque layer being cut out in the region of the security element.
  • a method for producing a multi-layer value document substrate comprising providing a first and at least one second layer, the first layer having at least one optical element and the value document substrate being produced by connecting the layers provided, the at least one second layer having a has varying transparency.
  • a varying transparency or a varied transparency can be set in a further optional method step or can take place simultaneously with the provision of the second layer in such a way that this layer already has a varying or varied transparency.
  • the multi-layer document of value substrate is, for example, a bank note which is formed from a number of layers or plies.
  • the individual layers can also be referred to as foils, which are connected in such a way that a document of value can be formed.
  • a document of value typically includes further components, as they are already known.
  • the present invention is not limited to a bank note per se, but rather a value document substrate can also be used, for example, in common security documents such as e.g. B. passports, ID documents, driving licenses or chip cards are used.
  • a first and a second layer are provided, which are generally present as a flat material.
  • this is a carrier layer which has an optical element.
  • An optical element can be present as a security feature that can be supported with the naked eye or machines or verified fully automatically.
  • the at least one second layer can be designed in such a way that it provides a protective function with respect to the first layer.
  • the document of value can comprise any number of layers, with the first layer providing the optical element and any further layers being arranged below or above this layer.
  • optical element It is important to ensure that the optical element is not covered or always remains visible.
  • different further layers can also be provided above and below the optical element, which are at least partially transparent or semi-transparent. It is also possible to partially cover the optical element, so that again only another part of the optical element remains visible. It is thus also possible to design the second layer in such a way that it interacts with the optical element and the two elements, ie the optical element and the second layer, provide a security feature in their interaction.
  • a variation here refers to the specific design of the transparency or the arrangement of transparent and non-transparent areas.
  • a varying transparency designates the possibility that the at least one second layer can be made transparent, semitransparent and opaque with regard to individual areas.
  • three areas can be provided in the at least one second layer, where a first area is transparent, a second area is semi-transparent, and a third area is opaque. It is possible to change the individual degrees of transparency within the second layer in such a way that the varying transparency provides a pattern.
  • any pattern can thus be placed over the optical element by means of the at least one second layer in such a way that the two features complement one another to form a security feature.
  • the at least one second layer can have alternating opaque and transparent strips in such a way that the underlying optical element is visible through the transparent strips and is covered by the opaque strips. It is particularly advantageous here to vary the transparency in such a way that opaque areas are configured in register.
  • “in register” means the congruent imprint of the lines of a type area on the front and the back. It is advantageous here that, in the case of an arrangement of the transparent or opaque areas that is in register, the areas on one side are arranged congruently with the areas on the other side of the value-document substrate. In this way, optical interference is avoided, since the transparent and opaque areas on the front side and the back side of the value-document substrate are arranged in the same way or in a mirrored manner.
  • the register accuracy it is also possible for the register accuracy to relate to just one side of the value-document substrate. This means that columns that contain text and are arranged next to each other are aligned in such a way that the rows are always at the same height.
  • the value document substrate itself is produced by connecting the layers provided, ie the first layer and the at least one second layer.
  • the person skilled in the art recognizes that further work steps that are not listed are typically necessary.
  • further elements have to be introduced into the value document substrate.
  • the connection can take place in such a way that a varying transparency is also produced in the same work step with the connection. This is possible, for example, by introducing heat during the connection. It is possible here to produce the second layer from a material whose transparency can be correspondingly varied under the action of heat.
  • the varying transparency can thus be produced in a separate process step, or layers that have already been correspondingly varied are already being used.
  • a method step of introducing a varying transparency into at least one of the second layers is therefore also proposed.
  • the varying transparency can be, for example, transparent and opaque areas that are in their working together to create a pattern. It is also possible here to vary the transparency gradually, such that there is a smooth transition from a transparent area to an opaque area.
  • the at least second layer is shaped in such a way that there are essentially transparent and essentially opaque areas.
  • This has the advantage that any pattern can be created by means of the varying transparency, which arise from transparent and opaque areas.
  • Essentially transparent or essentially opaque means that the areas do not have to be made completely transparent or opaque.
  • a person skilled in the art recognizes that a certain degree of matting of the at least one second layer can already create an essentially opaque surface.
  • the layers provided are connected in such a way that the second layer at least partially covers the optical element of the first layer.
  • This has the advantage that the at least one second layer can function as a protective layer and the at least one second layer can completely or partially cover the optical element. It is thus possible to combine further elements with the proposed characteristics. For example, the second layer cannot completely cover the optical element, so that a further layer can be arranged over the optical element.
  • the second layer can be arranged as the outer layer in such a way that at least one plane or further layer with printing elements is arranged between the first layer and the second layer.
  • the second layer only being applied after this printing process or these printing processes.
  • Further processing steps such as e.g. B. further printing processes and / or lining / laminating processes follow.
  • protection of the under the second layer and a combination of security features is possible.
  • other aspects such as different transparency of the second layer in combination with the printed layers and/or the first layer, can produce special optical effects for a viewer or a test sensor system for evaluating the authenticity of the document of value for reliable evaluation of authenticity.
  • the layers provided are connected in such a way that an essentially transparent region of the second layer covers the optical element of the first layer. This has the advantage that the proposed method creates a viewing window through which the optical element can be seen.
  • the layers are connected depending on an arrangement of the optical element of the first layer and the varying transparency of the at least one second layer.
  • This has the advantage that the optical element and the different regions of the second layer can be advantageously arranged relative to one another in such a way that, for example, a viewing window for the optical element or a specific pattern results. Care must be taken to ensure that the differently transparent areas are arranged in relation to the optical element in such a way that the optical element can be read and, if necessary, a further security feature is set. If, for example, the transparent and opaque areas form a pattern which is intended to interact with the optical element, then this pattern can also be applied advantageously in relation to the optical element in such a way that the desired optical effect occurs.
  • the layers are connected in such a way that the optical element of the first layer is arranged in register with at least one essentially transparent region of the at least one second layer.
  • This has the advantage that areas of the at least one second layer complement each other with the security feature.
  • the transparent or opaque areas are thus arranged over the optical element in such a way that they result in a single security feature when viewed together.
  • the optical feature is a security feature, a metal effect, a micro-optical effect, a hologram, a micro-mirror, lenses, a color shift effect, an interference effect, a print, an offset print, a background print, an intaglio print, a Numbering, any recess, a perforation, a laser cut, a window and/or a viewing window.
  • a color shift element is a security element in which the optical surface is divided into two areas. The Colourshift area clearly changes color when tilted, while the Colourfix area retains its colour. In a set viewing angle, the Colourshift area and the Colourfix area are the same in color, in a different set viewing angle, the two areas differ.
  • the at least one second layer forms a protective layer of the value document substrate.
  • the joining takes place using a laminating adhesive, a pressure-sensitive adhesive, a thermoplastic adhesive, a thermoplastic polymer layer, a thermoplastic layer, a post-crosslinkable layer or a joining of thermoplastic layers per se.
  • a laminating adhesive a pressure-sensitive adhesive
  • thermoplastic adhesive a thermoplastic adhesive
  • thermoplastic polymer layer a thermoplastic polymer layer
  • thermoplastic layer a post-crosslinkable layer or a joining of thermoplastic layers per se.
  • a post-crosslinkable layer can, for example, be a heat-sealing lacquer which, for. B. is activated by infrared or ultraviolet radiation.
  • the first layer is covered on both sides by at least one second layer in each case.
  • This has the advantage that any number of further layers can be arranged above and below the first layer and thus also that Value document substrate is particularly protected. In this case, it is possible to arrange the opaque or transparent areas in register in each case.
  • the transparency is varied using clouding, laser irradiation, UV irradiation, extrusion, thermoplastic embossing, grinding and/or mechanical surface treatment.
  • This has the advantage that different areas can be created in the at least one second layer in a simple manner and with little technical effort.
  • varying the transparency includes designing essentially transparent areas by means of heat sealing, hot embossing and/or applying pressure. This has the advantage that the varied transparency can already be implemented while the individual layers are being connected.
  • the varying transparency is designed with sharp edges or running. This has the advantage that the transparency in the at least one second layer can be varied gradually or abruptly in such a way that the individual areas are sharply delimited or just overlap one another.
  • a lacquer is applied to at least one outer side of the value document substrate.
  • the optical feature and the at least one second layer provide a security feature in their interaction.
  • At least one layer is formed from a selection from a group of materials.
  • the group includes several materials, some of which can be combined with each other, e.g. B. biodegradable polymers, polysaccharides, cellulose, thermoplastic starch, polylactic acid, polylactide PLA, polyhydroxy fatty acids PHF, polyhydroxybutyrate PHB, polyhydroxyvalerate PHV, polymers, polyethylene PE, polyethylene terephthalate PET, polybutylene terephthalate PBT, polyethylene naphthalate PEN, polypropylene PP, biaxially oriented polypropylene, BOPP, Non-woven fabric made of high density polyethylene and polyamide.
  • the at least one layer can also be a film, paper, felt material, non-woven material and/or a combination thereof.
  • the optical element in particular a security feature, can be arranged on, by means of lamination, covering and/or gluing, for example, or in the first layer.
  • the optical element can be a micro-optical security feature, security thread and/or imprint.
  • the optical element can be arranged in a layer above the first layer but between the first and second layers. An internal security is developed.
  • the second layer can also be configured with a further optical element, with the further optical element being arranged in, preferably under, the second layer, so that the further optical element is arranged between the first and second layers.
  • the first and/or second layer can already be provided with optical elements in advance, i.e. independently of other production steps, in particular parallel thereto.
  • At least one layer is provided by means of coextrusion. This has the advantage that several materials can be combined in one coextrusion and several layers can also be provided in one work step.
  • At least one layer is provided as a cellulosic paper having a proportion X of artificial polymeric materials in a range between 0 and 100% by weight.
  • tolerance ranges are created that make it possible to specify the features according to the invention in such a way that they can also serve as a security feature. Falling below or exceeding the specified tolerance values thus ensures that unauthorized reworking of the proposed features can be detected. In this way, security features are created that can be verified with the naked eye or with the help of machines.
  • a security feature is, very generally, a feature that makes it possible to distinguish an authorized method or product from a counterfeit. The proposed tolerance values are particularly suitable for this.
