Description

[0001] The invention relates to a method for producing a valuable or security document with a security hologram and to a valuable or security document with a security hologram incorporated therein.

[0002] German patent DE 100 07 916 A1 discloses a multi-layered, laminated card with an embedded security element featuring relief structures. This security element is embedded and laminated between two card layers.

[0003] A method for producing a prelaminate is known from DE 10 2017 100 719 A1. This method involves, in a first step, cutting out a window for a security feature into an inner layer, and in a second step, applying a film to the underside of the inner layer to cover the cut-out window. In a third step, the cut-out security feature is inserted into the cut-out window. Finally, a top layer is applied.

[0004] German patent application DE 10 2014 217 099 A1 discloses a method for producing a security document with a security hologram and such a security document. This security document consists of several substrate layers, in particular plastic layers, which are bonded together in a lamination process. A security hologram is applied between these layers. For this purpose, for example, adhesion promoters or adhesives can be used. The security document is preferably designed such that it has a window in at least one area in which the document body formed by the substrate layers is transparent to light of a wavelength between a top and a bottom surface of the document body.This window is associated with a security hologram, in particular a transmission hologram, wherein the transmission hologram is provided in a separate substrate layer, which extends over the entire surface between at least one upper and at least one lower substrate layer to form the document body.

[0005] Alternatively, a security document is known from DE 10 2014 217 099 A1 in which a window section is provided in at least one upper substrate layer or at least one lower substrate layer, and this window section is transparent to light of a specific wavelength. A reflection hologram is associated with this window section and is contained in a separate continuous layer between the at least one upper substrate layer and the at least one lower substrate layer. The reflection hologram can be verified by illuminating the window section.

[0006] EP 2 888 116 B1 discloses a method for producing a security or valuable document and a security or valuable document with a hologram in a visually visible window made of a multilayer composite, wherein the multilayer composite comprises a layer of at least one photopolymer in which at least one hologram is incorporated, and comprises at least one transparent optically switchable layer which does not become transparent upon heat or irradiation.

[0007] The invention is based on the objective of proposing a method for producing a valuable or security document with a security hologram, as well as a valuable or security document with a security hologram, in which a reduction of the number of layers for a document body and at the same time a secure integration of a security hologram are made possible.

[0008] This task is solved by a method for producing a valuable or security document, in which at least one cutout is made into at least one inner layer of a document body using a die-cutting tool, and subsequently a web material with at least one security hologram is provided, wherein a security hologram with a format corresponding to the size of the cutout of the inner layer is cut out of the web material using a die-cutting tool, and the cut-out format of the security hologram is inserted into the cutout of the at least one inner layer, and subsequently the at least one inner layer with the security hologram received in the cutout is fed to the at least one upper and / or at least one lower layer for further production of the document body.This method offers the advantage that the security hologram can be integrated into at least one inner layer and subsequently bonded to at least one upper and / or at least one lower layer to form a document body. This ensures the secure embedding of the security hologram. Simultaneously, a fully completed security hologram can be integrated into the manufacturing process of the valuable or security document and inserted into the die-cut. By positioning the die-cut security hologram within the die-cut of at least one inner layer, an additional substrate layer containing the security hologram can be eliminated.

[0009] The inner layer with the security hologram embedded in the die-cut, the at least one upper layer, and the at least one lower layer are joined together and laminated to form a document body. This allows for the secure integration of the security hologram into the document body, which, due to the lamination, preferably has a material-bonded connection between the individual layers.

[0010] A preferred embodiment of the method provides that the die-cutting into the at least one inner layer is performed with the same die-cutting tool as the die-cutting of the security hologram format, or that the security hologram format is die-cut with a separate die-cutting tool that has the same format as the die-cutting tool. In the first embodiment, one and the same die-cutting tool can be used for both producing the die-cut and for die-cutting the security hologram format, thus enabling particularly precise positioning and alignment of the security hologram within the die-cut. The second embodiment allows for a higher cycle time in production.

[0011] Furthermore, preferably at least one upper and / or lower layer is designed with a transparent area for the window or window section. In such a case, a view of the at least one inner layer from outside the window section can be prevented, so that further security features may be concealed therein that are not visible from the outside.

[0012] Alternatively, at least one upper and / or at least one lower layer can be designed as a transparent layer.

[0013] Another preferred embodiment of the method provides that a further security feature is incorporated into the window or window section of the at least one upper and / or at least one lower layer before it is connected to the at least one inner layer. For example, another hologram can be incorporated into the window or window section, so that two superimposed holograms in different layers are possible.

[0014] Furthermore, a transmission hologram, serving as a security hologram, is incorporated into the document body through a window that allows light to pass through from top to bottom. This allows a security hologram to be protected within the document body through a transparent window for transmitted light.

[0015] The object underlying the invention is further achieved by a security document produced according to a method of the preceding claims, in which at least one inner layer is provided between the at least one upper and at least one lower layer, together forming a document body, wherein the at least one inner layer has a cutout and a security hologram has a format corresponding to the cutout and is inserted into the cutout. By adapting the format of the security hologram to the cutout in the at least one inner layer, a precise insertion of the security hologram into the document body can be achieved. This allows for a more stable production process for such security documents with at least one integrated security hologram.

[0016] The document body, which has a light-transmitting window extending from the top to the bottom of the document body, incorporates a transmission hologram as a security hologram.

[0017] Furthermore, an additional security feature can be incorporated into the window or window section in at least one upper and / or at least one lower layer. By overlaying the security hologram provided in the inner layer with the additional security hologram, increased counterfeit protection can be achieved.

[0018] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features that can be derived from the description and the drawings can be applied individually or in any combination according to the invention. The drawings show: Fig. 1 a perspective view of a first embodiment of a security document with a security hologram, Fig. 2 a perspective view of an alternative embodiment of the security document according to Fig. 1, Fig. 3 a schematic view of a first procedural step for the production of the security document according to Fig. 1, Fig. 4 a perspective view of a further procedural step for the production of the value or security document according to Fig. 1, and Fig. 5 a perspective view of a further procedural step for the production of the value or security document according to Fig. 1.

[0019] In Fig. Figure 1 shows a first embodiment of a security document 11. This security document 11 consists of at least one upper layer 3 and at least one lower layer 5. At least one inner layer 4 is provided between them. The layers 3, 4, and 5 can be formed from a single layer or from multiple layers. These multiple layers can form a foil booklet. These layers 3, 4, and 5 are bonded together by lamination to form a document body 6. This document body 6 can be cut to a final format with an outer contour 9 by a cutting or die-cutting process, such that the upper, middle, and lower layers 3, 4, and 5 have a common circumferential end face 2. These preferably lie in a common plane.

[0020] Layers 3, 4, and 5, used to manufacture the document body, may consist of one or more plastic materials. In particular, these include or are composed of polycarbonate (PC). Other alternatives include: bisphenol-A polycarbonate, carboxy-modified PC, polyethylene terephthalate (PET), its derivatives such as glycol-modified PET (PETG), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polybutylene terephthalate (PBT), polyvinyl alcohol (PVA), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile butadiene styrene copolymer (ABS), and / or their derivatives. Layers 3 and 5 may also consist of paper and / or cardboard or mixtures of the aforementioned materials.The at least one inner layer 4 can also consist of paper, cardboard or a mixture of the aforementioned materials, in contrast to the outer layers 3, 5.

[0021] A window 12 is provided in the security document 11. Preferably, congruent window sections 18 are provided in the at least one upper and at least one lower layer 3, 5, which are transparent to light of a specific wavelength. In particular, this area of ​​the window 12 is transparent. The at least one inner layer 4 has a cutout 14 in the area of ​​the window 12. A security hologram 16, which is die-cut to a format corresponding to that of the cutout 14, is inserted into this cutout 14. This security hologram 16 is securely integrated by lamination after the document body 6 has been manufactured. Preferably, the security hologram 16 is designed as a volume transmission hologram. Such a volume transmission hologram is known from DE 10 2014 217 099 A1, to which full reference is made.

[0022] The area of ​​at least one upper and at least one lower layer 3, 5 surrounding the window 12 can be non-transparent. Alternatively, at least one upper layer 3 and / or at least one lower layer 5 can be completely transparent. Depending on the intended use of this valuable or security document 11, information from the document holder can be applied to the inner layer 4, to at least one upper and / or at least one lower layer 5, or only partially applied, so that when viewed from the document body 6, this partial information in each layer serves as a single piece of information.

[0023] In Fig. 2 is an alternative embodiment of the value or security document 11 to Fig. Figure 1 shows this embodiment. This embodiment differs in that a window section 18 is provided only in the at least one upper layer 3. Alternatively, this window section 18 can also be provided only in the at least one lower layer 5. In the at least one inner layer 4, the window section 18 is associated with the cutout 14. The security hologram 16 is provided in this cutout 14. In this embodiment, the security hologram 16 is designed as a reflective hologram. Reference is made in full to DE 10 2014 217 099 A1 regarding the manufacture of such a reflective hologram. Furthermore, the structure of the security document 11 corresponds to that shown in Figure 11. Fig. 2 dem in Fig. 1 described value or security document 11 and the alternative embodiments.

[0024] In the Fig. 3, Fig. 4 and Fig. 5 are schematically individual procedural steps for the production of the value or security document 11 according to Fig. Figure 1 illustrates the process. In one step, the at least one inner layer 4 is provided and fed to a die-cutting station 25. The at least one inner layer 4 can be provided as sheet material or web material. A die-cutting tool 26 is fed onto the at least one inner layer 4 and the cutout 14 is made. Subsequently, the at least one inner layer 4 with the cutout 14 is fed to another processing station 25. For example, a web material is shown below the at least one inner layer 4 as roll material 29, which comprises several completed security holograms 16. With a die-cutting tool 31, the security hologram 16 is cut out of the web material into a format. This format corresponds to the size of the cutout 14 in the at least one inner layer 4. The cut-out security hologram 16 is inserted into the cutout 14.Preferably, a counter-tool 32 is provided opposite the punching tool 31. This ensures that the safety feature 16 is inserted flush into the cutout 14 of the at least one inner layer 4.

[0025] In a subsequent step according to Fig. 5. The at least one inner layer 4 with the security hologram 16 inserted into the die-cut 14 is fed to a further processing station 34. In this processing station 34, the at least one upper layer 3 or the at least one lower layer 5 or both are also fed, so that lamination to form the document body 6 subsequently takes place according to Fig. 1 can be done.

[0026] The at least one upper layer 3 and at least one lower layer 5 can already be cut to a format corresponding to the at least one inner layer 4, so that they can be laminated together in a stack to form the document body 6. Alternatively, the at least one upper layer 3 and the at least one lower layer 5 can also be supplied as roll material, with the at least one inner layer 4 positioned between them. Lamination is then carried out, and subsequently the document body 6 is die-cut to the desired size.

[0027] The production of the alternative embodiment of the security document 11 according to Fig. 2 is carried out analogously to the previously described process steps. The difference is, for example, that at least one lower layer 5 is designed without window section 18, and a reflective hologram is used as the security hologram.

[0028] This security document (11) can be in the form of a card, for example in ID-1, ID-2, or ID-3 format. Such a security document (11) can also be a national identity card, driver's license, visa, check / credit card, company ID, proof of authorization, membership card, voucher, or similar document.
