Description

[0001] The present invention relates to securities with identification features. In particular, the invention relates to a securities document and a method for producing a securities document.

[0002] Valuable documents can take the form of banknotes, card-shaped data carriers such as identity cards or payment cards, or data pages for passports. Such valuable documents typically feature identification or security features such as holograms to verify their origin and detect counterfeits. Card-shaped data carriers and passports, in particular, are often equipped with interfaces to enable data transfer between the document and an external reader. These valuable documents often consist of a laminated layered structure. Valuable documents can also be in the form of banknotes, which are typically based on a thin and flexible paper or plastic substrate.

[0003] It is an object of the present invention to provide a security document with improved identification properties.

[0004] This problem is solved by the subject matter of the independent claims. Further features of the invention will become apparent from the dependent claims, the following description, and the figures.

[0005] According to one aspect, a value document is provided. The value document comprises a value document body and a recessed area provided in the value document body, wherein the recessed area contains a medium having a particulate and / or granular composition and / or a liquid composition.

[0006] The inventive document's identification properties can be improved by providing identification information through a specific composition located within the recessed area. This identification information provided by the composition can have a time-varying information content, as it may be a particulate, granular, or liquid composition that can change its spatial distribution or arrangement within the recessed area.

[0007] The document can also be designed with optical or visually perceptible properties that convey information to the viewer and / or create an aesthetic effect. For example, the chosen composition can produce a colored representation that is either static or changes over time.

[0008] The document body can have a multi-layered and / or stacked structure. Individual layers of the document body may be laminated, meaning they have been bonded together under pressure and heat. This is particularly common when the document is a card-shaped data carrier or a data page of a passport book.

[0009] The body of the security document can also comprise a paper substrate, a plastic substrate, in particular a plastic film, or a hybrid substrate, that is, a combination of a paper substrate and a plastic substrate. This is preferably the case when the security document is a banknote.

[0010] The security document may include a chip module and / or an antenna element, which are also integrated into or attached to the document body. The antenna element may be electrically coupled to the chip module and function as a contactless interface for communication with an external reader. Similarly, contact surfaces may be provided on the security document, which are electrically coupled to the chip module and function as a contact interface for communication with an external reader.

[0011] The recessed area can define a cavity or void within the document body. The recessed area can be closed, preventing the medium containing the composition from escaping. This can mean that the recessed area is filled with the medium during the manufacturing process of the document body and then closed, remaining sealed throughout the document's service life or circulation period. The document body and the recessed area are specifically designed to prevent the medium or its composition from escaping. The recessed area can be gas-tight and / or liquid-tight.

[0012] The medium can be a particulate composition, which may include, for example, magnetic particles such as magnetic effect pigments. These magnetic particles can be present in a loose or unconsolidated form within the recessed area, allowing the particles to shift relative to one another and thus change their arrangement.

[0013] The medium can also be a granular composition, for example, incorporating a granular substrate such as sand or the like. The granules can also be loose or unconsolidated within the recessed area, allowing them to shift relative to one another and thus change their arrangement. The recessed area can have a specific shape, such as two chambers connected by a constricted section, giving it the shape of an hourglass. The granular composition within the hourglass-shaped recess can thus provide an hourglass function. The recessed area and the composition can be visible to the user from the outside, allowing the user to activate the hourglass function by rotating the document.

[0014] The medium can also be a liquid composition, such as water, a water-based solution, or any other liquid or viscous substance. The liquid composition can also be freely mobile and distributed within the recessed area, allowing it to shift or redistribute itself. The recessed area can have a specific shape, creating particular flow characteristics or effects for the liquid composition within it, which are visible to an external observer of the document. This can produce effects similar to those of a lava lamp. The liquid composition can be a mixture of several different liquid substances or a mixture of liquid and solid substances.A heterogeneous mixture of substances can be used as the liquid composition. For example, the liquid composition can contain oil and water, so that the two substances remain separate at all times and the oil moves freely within the water in the form of bubbles. The document body can also have a light source that shines into the recessed area, creating a lava lamp effect.

[0015] By using a liquid composition as the medium, a spirit level can also be incorporated into the document body. For this purpose, the composition can contain a gas, such as air, and water, with a gas bubble being able to move freely within the water to indicate the document's orientation to the user, similar to a spirit level.

[0016] According to one embodiment, the medium is designed to change its spatial arrangement and / or its spatial distribution within the recess area depending on the orientation of the security document and / or depending on an external influence on the security document.

[0017] The medium, which has this composition, can be freely arranged within the recessed area. It can contain different concentrations or different substances or mixtures of substances in different areas. Due to this free movement, the particles and / or grains and / or liquids can freely arrange, align, redistribute, etc., within the recessed area. In other words, the particles and / or grains and / or liquids can shift relative to each other within the recessed area, resulting in a time-varying appearance caused by the medium.

[0018] The spatial rearrangement or redistribution of the composition within the recessed area can be based on the orientation of the valuable document. For example, if a user rotates the valuable document, the medium or composition can shift, redistribute, realign, etc., due to the force of gravity.

[0019] However, the spatial rearrangement or redistribution of the composition can also occur as a result of external influences, such as temperature-related effects or the application of a magnetic field to the document. For example, if the composition contains magnetic particles or grains, then a rearrangement or redistribution of the composition within the recessed area can be caused by a magnetic field whose magnetic field lines cross the document.

[0020] According to one embodiment, the recess area is provided in the form of a closed cavity located within the security document body, wherein the medium is provided in the cavity, in particular enclosed.

[0021] The cavity may be fully or partially visible from outside the security document. In particular, the document body may have one or more transparent layers through which the cavity is visible to a user or viewer of the document. In the case of an hourglass-shaped recess, as explained above, the user can see the entire cavity forming the hourglass shape and thus the arrangement of the granular composition within it.

[0022] According to one embodiment, the document body comprises a composite layer of a plurality of layers and the recess area is arranged within the composite layer, wherein the plurality of layers includes a cover layer which covers the recess area.

[0023] The cover layer can form a boundary between the recessed area and the surroundings of the valuable document. The cover layer can be transparent if the recessed area and the medium it contains are intended to be visible to the user of the valuable document from the outside.

[0024] The outer layer can also be opaque or lightproof if the recessed area and the medium it contains are not intended to be visible to the user of the valuable document from the outside. In particular, the medium can provide a security function or serve as a concealed security element within the valuable document itself, which should not be recognizable from the outside. For example, the composition can have magnetic properties that can be detected by a corresponding detection device when the valuable document is brought near such a device. Based on these magnetic properties of the composition, the authenticity of the valuable document can then potentially be verified.For example, the composition may contain a specific amount of magnetic pigments or particles that provide certain magnetic properties for the valuable document, so that the authenticity of the valuable document can then be determined based on the specific magnetic properties.

[0025] According to one embodiment, at least one layer, for example the aforementioned top layer, of the layered composite is designed to be at least partially transparent or semi-transparent, so that the medium is visible to a user through the at least one at least partially transparent or semi-transparent layer.

[0026] This can mean that, as part of a manufacturing process for the security document body, the recess area is provided within it, and subsequently a transparent or semi-transparent layer is applied over the recess area, so that the transparent or semi-transparent layer covers and seals the recess area while also allowing the medium located in the recess area to be visible through the transparent or semi-transparent layer.

[0027] According to one embodiment, the recess area has an inner boundary surface, wherein the inner boundary surface has personalization information that is visible to a user through the at least one at least partially transparent or semi-transparent layer.

[0028] The boundary surface can be part of a boundary wall of the recess area, with the boundary surface facing the recess area. The personalization information can be applied to the boundary surface using a laser process. In this process, the personalization information can be applied to the boundary surface through a lens structure that may also be incorporated into the document body, with the laser beam used to apply the personalization information directed through the lens structure. Alternatively, the personalization information can also be applied to the boundary surface by embossing or engraving.

[0029] According to one embodiment, the security document further comprises a lens structure which is arranged in the security document body in such a way that the medium is visible to a user through the lens structure.

[0030] The lens structure can be designed as an uppermost layer over the recessed area and simultaneously form a sealing layer for the recessed area, preventing the medium from escaping. The lens structure can be configured to provide an optical effect with respect to the medium within the recessed area. A tilting effect can be created such that the medium is visible through the lens structure only at a specific viewing angle and not at other viewing angles. The lens structure can comprise one or more lenses. For example, rod lenses or spherical lenses can be used.

[0031] According to one embodiment, the recess area comprises a separating layer which divides the recess area into a first chamber and a second chamber, wherein the medium is provided in at least one of the first chamber and the second chamber.

[0032] The separating layer can be incorporated directly during the manufacturing of the document body. The separating layer can also be at least partially transparent or semi-transparent. Alternatively, the separating layer can be opaque, in which case the document body preferably has transparent or semi-transparent top layers on both sides, so that a medium in the first chamber is visible from one side of the document through a first top layer, and a medium in the second chamber is visible from the other side of the document through an opposing second top layer. The medium in the first chamber can be the same as the medium in the second chamber. However, different media with different compositions can also be provided in the two chambers. Additional separating layers can be provided, dividing the recessed area into further additional chambers.

[0033] According to one embodiment, the security document has a receiving unit which is arranged at least partially or completely within the recess area, wherein the medium is provided in the receiving unit, in particular enclosed.

[0034] The receiving unit can be a sealed container. In particular, a separate container holding the medium can be inserted into the recess. This further simplifies the production of the security document according to the invention, as the medium can be filled into the receiving unit or container before the receiving unit or container is inserted into the recess. The material of the security document body can thus be kept separate from the medium, preventing any reaction between the medium and the material of the security document body. Therefore, the medium with the required composition can be selected independently of any material chosen for the security document body.

[0035] According to one embodiment, the medium provided in the recess area is visible to a viewer of the security document through a section of the document's material.

[0036] The material section can be a transparent, window-shaped section, which is, for example, enclosed by the aforementioned top layer.

[0037] In this way, an optical or visual effect can be provided to the user or viewer of the document. The viewer can use this visualization, for example, to grasp optical information, identification information, or other information such as time information by examining the cutout area and the medium it contains.

[0038] When using a particulate or granular composition, such as sand, a sand image can be created, resulting from differently colored sand particles or grains. This sand image can be static or change due to the user rotating the document, as described above.

[0039] Similarly, liquid compositions can also be used as the medium. For example, the user might perceive a kind of lava lamp effect.

[0040] The document body may have a light source that at least partially illuminates the recessed area and / or the medium contained therein.

[0041] According to one embodiment, the document body has a lockable opening through which the medium can be fed into or removed from the recess area.

[0042] The opening can be conduit-like or tubular. It can extend through part of the document body to connect the recessed area to the document's surroundings. This allows the recessed area to be filled with the medium even after the document body has been manufactured. The opening is closable, preventing the medium from escaping once it has been placed inside. The opening also offers the advantage of allowing the medium to be removed from the document body, for example, to insert a different medium into the recessed area.

[0043] According to one embodiment, the medium is designed to provide a multicolored, user-visible display by changing its spatial arrangement and / or distribution within the recess area. Additionally or alternatively, the medium is designed to provide sensor-detectable authentication information for the valuable document by changing its spatial arrangement and / or distribution within the recess area.

[0044] The particles, grains, and / or liquids contained in the composition may exhibit different colors. By realigning or rotating the document, these differently colored particles, grains, and / or liquids within the composition can redistribute themselves, creating a new overall image for the viewer.

[0045] Furthermore, magnetic properties can vary due to changes in the spatial arrangement and / or distribution of the medium, which can be detected by a suitable sensor. The medium can be hidden within the document body, meaning it is not visible to a user of the document, thus concealing authentication information within the document.

[0046] According to one embodiment, the security document is a card-shaped data carrier, a data page of a passport book, or a banknote.

[0047] A card-shaped data carrier is, for example, an identity document, a chip card or a payment card.

[0048] According to one aspect, a procedure for producing a security document is provided. In one step of the procedure, a security document body is provided. In a further step, a recess is provided in the security document body. In a further step, a medium having a particulate, granular, and / or liquid composition is introduced into the recess. In a further step, the recess is sealed to prevent the medium from escaping the security document body. The procedure steps can be carried out in the specified sequence.

[0049] According to one embodiment, the step of providing the recess area in the document body comprises providing the recess area in a layered composite of a plurality of layers, wherein the recess area is closed by applying at least one layer of the plurality of layers over the recess area, so that the medium is visible to a user through a material section of the at least one applied layer.

[0050] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings.

[0052] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0053] Fig. Figure 1 shows a valuable document 1, for example, a card-shaped data carrier, a data page of a passport book, or a banknote. The valuable document 1 comprises a valuable document body 10, which has a recessed area 12 containing a medium 14. The recessed area 12 extends within the valuable document body 10. The medium 14 can have a particulate composition and / or a granular composition and / or a liquid composition, or be formed by such a composition.

[0054] The medium 14 can completely or only partially fill the recessed area 12. In the Fig. In the example shown, the medium 14 partially fills the recess area 12. The recess area 12 is shaped like an hourglass, whereby the medium 14 contained therein, for example a granular composition such as sand, collects in a lower area of ​​the recess area 14 due to a downward force of gravity (indicated by arrow 2).

[0055] The medium 14 is designed to change its spatial arrangement and / or its spatial distribution within the recess area 12 depending on the orientation of the security document 1. If the security document body 10 is rotated, the medium 14, due to its, for example, granular composition, can rearrange or redistribute itself within the recess area 12, which in turn is caused by the downward force of gravity. In this way, the hourglass function can be derived from the in Fig. The example shown in Figure 1 illustrates this effect with a value document 1. However, this is merely an example, and other configurations with various types of redistributable compositions, such as particulate, granular, or liquid compositions, can be used to achieve such redistribution effects. The compositions are characterized, in particular, by a loose or dispersible nature, which enables the redistribution of the composition material within the recessed area 12.

[0056] However, the redistribution can also be caused by external influences on the value document 1, such as a temperature change, which can cause a redistribution of the composition contained in the recess area 12, or a magnetic field, which can cause an alignment of the particles or grains contained in the recess area 12.

[0057] The recessed area 12 can be provided as a closed cavity 13 extending within the document body 10, with the medium 14 being provided in the cavity 13. The medium 14, or the exemplary compositions mentioned above, therefore cannot escape from the cavity 13 and always remain within the cavity 13.

[0058] Fig. Figure 2 shows a layered composite 20 of a security document 1 with a security document body 10, which has a recessed area 12. This can be the part relating to the Fig. The described security document 1 is a composite layer. The composite layer 20 comprises a first layer 21, a second layer 22, a third layer 23, a fourth layer 24, and a fifth layer 25, which may be bonded together, for example, by lamination. The second layer 22, the third layer 23, and the fourth layer 24 together form the recess 12, i.e., the cavity 13, within the security document body 10 of the security document 1. More or fewer layers may also be provided to define the recess 12. The first layer 21 is the uppermost layer of the composite layer 20, i.e., a cover layer 21. The cover layer 21 may also have several layers or sub-layers.

[0059] The cover layer 21 forms a boundary between the recess area 12 and the surroundings of the security document 1. The medium 14 provided in the recess area 12 (see Fig. 1) can be visible to an observer of the security document 1 from the outside through a material section 11 of the document body 10, in particular through a material section 11 of the cover layer 21. For this purpose, the material section 11 or the entire cover layer 21 can have transparent material properties.

[0060] Fig. Figure 3 shows a security document 1 with a security document body 10, which has a recess area 12 and an opening 18 for the recess area 12. This can be the document related to the Fig. 1 and Fig. The described document 1 is a valuable document. The opening 18 is preferably closable, wherein the medium 14 can be fed into or discharged from the recess 12 when the opening 18 is open, and wherein the medium 14 cannot escape from the recess 12 when the opening is closed. A closure inserted into the opening 18 can be bonded to the valuable document body 10 by a material bond, a force bond, or a form bond to seal the opening 18 gas-tight and / or liquid-tight. In the case of a material bond between the closure and the valuable document body 10, the material of the closure can fuse with the material of the valuable document body 10. Thus, the opening 18 would then no longer be visible to an observer from the outside.

[0061] The Fig. Figures 4A to 4D show a manufacturing sequence for producing a value document 1, for example, the one relating to the Fig. 1, Fig. 2 to Fig. 3 explained securities document 1.

[0062] Fig. Figure 4A shows a sectional view of a layered composite with a second layer 22, a third layer 23, a fourth layer 24 and a fifth layer 25.

[0063] Fig. 4B shows a top view of the layered structure of Fig. 4A. The uppermost, second layer 22 can be seen, wherein a recess area 12 has been introduced into the layer composite, for example by means of a die or punch tool which was pressed into the layer composite by pressing onto the second layer 22 and penetrates one or more layers of the layer composite to form the recess area 12.

[0064] Fig. 4C shows a layer composite of Fig. The top layer 21 applied in 4A or 4B can represent the first layer 21 already introduced above. Before applying the top layer 21 to the layer composite formed from layers 22, 23, 24 and 25, the medium 14 (see below) can be applied. Fig. 1) be introduced or filled into the recess area 12. Only then is the top layer 21 preferably applied to the layer composite formed from layers 22, 23, 24 and 25 in order to close the recess area 12 and thus prevent the medium 14 from escaping from the recess area 12.

[0065] Fig. 4D shows the layered structure of Fig. 4A exhibiting the security document body 10, which is composed of all layers 21, 22, 23, 24 and 25. This can be the one in Fig. The layer composite 20 shown in the 2, wherein the first layer 21 or cover layer 21 serves as a cover for the recess area 12 or cavity 13.

[0066] The recess area 12 can be designed to be gas-tight and / or liquid-tight to prevent the medium 14 from escaping from the recess area 12.

[0067] Fig. Figure 5A shows a layered composite for a security document body 10 with a recessed area 12. The layered composite can be like the one in Fig. 4A is formed as a layer composite comprising layers 22, 23, 24 and 25, wherein the recess area 12 extends through the second layer 22, the third layer 23 and the fourth layer 24.

[0068] Fig. Figure 5B shows a tool 100 for creating the recess area 12 in the layered composite of the security document body 10. In this example, three protrusions 110, each in the form of an hourglass, are arranged on the tool 100, so that by pressing the tool 100 onto the layered composite, corresponding recess areas 12 can be created. The further description, however, is based on the explanation of an example with a recess area 12.

[0069] Fig. 5C shows a layer composite of Fig. 5A applied top layer 21, which can represent the first layer 21 already introduced above. Before applying the top layer 21 to the layer composite formed from layers 22, 23, 24 and 25, the medium 14 (cf. Fig. 1) be introduced or filled into the recess area 12. Only then is the top layer 21 preferably applied to the layer composite formed from layers 22, 23, 24 and 25 in order to close the recess area 12 and thus prevent the medium 14 from escaping from the recess area 12.

[0070] Fig. 5D shows the layered structure of Fig. 5A exhibiting the security document body 10, which is composed of all layers 21, 22, 23, 24 and 25. This can be the one in Fig. The layer composite 20 shown in the 2, wherein the first layer 21 or cover layer 21 serves as a cover for the recess area 12 or cavity 13.

[0071] The recess area 12 can be designed to be gas-tight and / or liquid-tight to prevent the medium 14 from escaping from the recess area 12.

[0072] Fig. Figure 6A shows two layer stacks 40, 50, each with a part 31, 32 of a receiving unit. In the first layer stack 40, which in this case consists of the two layers 41 and 42, a first partial recess area 12a can be provided in which a first part 31, for example a semi-finished product in the form of a half-shell, of the receiving unit is provided. In the second layer stack 50, which in this case consists of the two layers 51 and 52, a second partial recess area 12b can be provided in which a second part 32, for example another semi-finished product in the form of another half-shell, of the receiving unit is provided.

[0073] Fig. 6B shows the two in Fig. 6A layer stack 40, 50 with the medium 14 (cf. Fig. 1) in the second part 32 of the recording unit.

[0074] Fig. Figure 6C shows a layer structure with the two layer stacks 40 and 50. Fig. 6A and Fig. 6B in an assembled state. Here, the two parts 31, 32, that is, the two half-shells, are joined together in such a way that they jointly form the receiving unit 30 in which the medium 14 is enclosed. The receiving unit 30 is arranged in the recessed area 12 and can function as a container in which the medium 14 is held.

[0075] Fig. 6D shows a top view of the structure according to the Fig. 6A to 6C produced security document body 10. The produced security document body 10 already exhibits the features already in Fig. Figure 6C shows the receiving unit 30, which is arranged in the recess area 12 and in which the medium 14 is received. The medium 14 received in the receiving unit 30 can be seen through a transparent material section of the document body or the cover layer 21 described above (see Figure 6C). Fig. 2) the document body 10 is recognizable through it. The receiving unit 30 may also have one or more transparent material sections through which the medium 14 is visible.

[0076] Fig. Figure 7 shows a flowchart for a procedure for producing a security document, for example, for producing security document 1 as explained in relation to the preceding figures.

[0077] In step S1, a document body 10 is provided. In step S2, a recess 12 is provided in the document body 10. In step S3, a medium 14, which has a particulate and / or granular composition and / or a liquid composition, is introduced into the recess 12. In step S4, the recess 12 is sealed, in particular gas-tight and / or liquid-tight, to prevent the medium 14 from escaping the document body 10.

[0078] The Fig. Figures 8A to 8C show a manufacturing sequence for producing and shaping a recessed area 12 for a document body 10. First, a layered composite 20 is provided. As already Fig. 2 shows the Fig. 8A such a layered composite 20 for a valuable document body 10.

[0079] The layer assembly 20 comprises a first layer 21, a second layer 22, a third layer 23, a fourth layer 24, and a fifth layer 25, which can be bonded together, for example, by lamination. The first layer 21 can be a so-called transparent overlay. The second layer 22 can be an opaque film onto which the overlay is printed. The third layer 23 can represent a functional layer containing an antenna and / or a chip module (not shown in the figures). This is followed by the fourth layer 24, which can again be an opaque film suitable for printing. Finally, the fifth layer 25, for example, a transparent film, can be applied or printed onto the fourth layer 24. It should be noted that the layer assembly 20 can have more or fewer layers 21, 22, 23, 24, and 25 than shown.

[0080] Fig. 8B shows the layer combination 20 from Fig. 8A with a recessed area 12 provided therein. In a first variant, recesses are individually created in the individual layers 22, 23, 24 before these layers are joined together to form the layer composite 20. Here, a recess is created in the second layer 22, the third layer 23, and the fourth layer 24, which will later form the recessed area 12. This can be achieved by punching, laser cutting, or other methods. Subsequently, the fourth layer 24 with the recess and the fifth layer 25 without a recess are placed on top of each other and bonded together. Then, a transparent and / or thermally stable layer 12a can be inserted into the recess of the fourth layer 24 and thus into the future recessed area 12, with the transparent and / or thermally stable layer 12a, for example, abutting the fifth layer 25 from the inside.This transparent and / or thermally stable layer 12a can, for example, be made of glass, polyimide (PI), ceramic, or combinations thereof. Subsequently, the third layer 23 and the fourth layer 24 can be precisely aligned over the fourth layer 24 and bonded to it, so that the [material] in [location] is [context]. Fig. The recess area 12 shown in Figure 8B is created. Subsequently, a thermally stable support structure 12c in the shape of the recess area 12, for example a circular or ring-shaped support structure 12c, can be inserted into the recess area 12. The support structure 12c can consist of a dosable, thermally stable material. The support structure 12c can, for example, be made of glass, polyimide (PI), ceramic, or combinations thereof. Subsequently, the medium 14 (see Figure 8B) can be inserted. Fig. 1) That is, the particulate and / or granular and / or liquid composition is introduced into the cavity 13 formed by the support structure 12c and the layer 12a. Subsequently, a further transparent and / or thermally stable layer 12b can be applied, which closes the recess area 12 or the cavity 13. This further transparent and / or thermally stable layer 12b can, for example, be made of glass, polyimide (PI), ceramic, or combinations thereof. Subsequently, the further transparent and / or thermally stable layer 12b can be covered with the first layer 21, that is, with the at least partially transparent overlay film. Subsequently, the layers can be laminated as already described. One of the layers 12a or 12b can be transparent, whereas the other of the layers 12a or 12b can be non-transparent or opaque. In the latter case, the introduced medium 14 (cf. Fig. 1) will later be visible to a user only from one page of value document 1.

[0081] Layers 12a and / or 12b may also include a lens structure 17 to achieve certain optical effects. Layers 12a and / or 12b may be arranged in the document body 10 such that the medium 14 (cf. Fig. 1) is visible to a user through the lens structure 17.

[0082] Fig. 8C shows the layer composite 20 made of Fig. 8A with a recessed area 12 comprising two chambers 19a and 19b. The recessed area 12 has a separating layer 19 which divides the recessed area 12 into a first chamber 19a and a second chamber 19b. The in Fig. 8C not shown medium 14 (see also Fig. 1) is provided in at least one of the first chamber 19a and the second chamber 19b. Due to the division into the first chamber 19a and the second chamber 19b, two different media or materials can be provided in the recess area 12, each provided in chambers 19a and 19b, respectively. These can each be a particulate and / or granular and / or liquid composition. Regarding the further details in Fig. The components shown in 8C refer to the components of the Fig. 8B referred to, which is also in the exemplary embodiment of the Fig. 8C may be present or can be combined with it.

[0083] The Fig. Figures 9A to 9C show a manufacturing sequence for producing and shaping a recessed area 12 for a document body 10. First, a layered composite 20 is provided. As already Fig. 2 shows the Fig. 9A such a layered composite 20 for a valuable document body 10.

[0084] The layered assembly 20 comprises a first layer 21, a second layer 22, a third layer 23, a fourth layer 24, and a fifth layer 25, which can be bonded together, for example, by lamination. The document body 10 formed from the layered assembly 20 can then be fully produced, i.e., assembled, so that all layers 21, 22, 23, 24, and 25, or all film layers 21, 22, 23, 24, and 25, are permanently bonded together. Subsequently, the recessed area 12 can be provided in the document body 10, or the layered assembly 20, for example, by milling. The recessed area 12 has the form of a circle or a ring, but can assume any desired shape (for example, the shape of a star or an hourglass (cf. Fig. 1) or the shape of a bank logo). The actual recess area 12 can be provided in layers 22, 23, and 24, with recesses 21a and 21b being provided in the uppermost layers 21 and 25 of the layered assembly 20, i.e., in the overlays 21 and 25, respectively, which are larger (for example, in diameter) than the recess area 12. A finishing element 21c and 21d can be inserted into each of these recesses 21a and 21b, as indicated by arrows in the Fig. 9B is shown.

[0085] The Fig. 9B therefore shows the layer combination 20 made of Fig. 9A and the two end elements 21c, 21d for closing the recess area 12. In Fig. Figure 9B shows in particular how the end elements 21c and 21d are inserted into the recesses 21a and 21b. The end elements 21c and 21d can be fixed in the recesses 21a and 21b using an adhesive system (not shown here). The adhesive system can, for example, be a two-component adhesive or a heat- or UV-activated adhesive tape. The end elements 21c and 21d can also include or form lens structures or lenses to create additional optical effects, as described in relation to the Fig. 8B was described. It may be provided that only one side of the security document body 10 is equipped with a closing element 21c or 21d. Preferably, at least one of the closing elements 21c and 21d is transparent.

[0086] Fig. Figure 9C shows a layer assembly 20 with a recessed area 12 and personalization information 16 provided therein. The information contained in the Fig. The variant shown in 9C is an alternative embodiment to the one shown in the Fig. The variant shown in Figure 9B is used. In this variant, the cutout area 12 is not created through the entire document body 10, but only in layers 22 and 23. The closing element 21c in this variant can be a concave lens or lens structure. This can, for example, enlarge, reduce, or distort information 16, in particular personalization information 16 or text 16 or a string 16, which has been placed in a boundary surface 15 of the cutout area 12. The information 16 can thus be associated with an optical effect. In particular, the information 16 can therefore also be used as a security element. For example, a card verification number (so-called CVC) can be hidden in the cutout area 12 in this way.

[0087] In addition to or instead of the information 16, a light source (not shown in the figures), such as an LED, may be located in or on the recess area 12, which illuminates or at least partially or completely the recess area 12. The end element 21c may include or form a diffuser designed to scatter light from the light source.
