The security element (1) comprises a carrier layer (2) and a motif (3) as a security feature. Provision is made for the motif (3) to be divided into several individual motif sections (4), with an interrupted region (5) being arranged between adjacently arranged motif sections (4) in such a way that an observer has the impression that the motif (3) is covered or interrupted by the interrupted region (5).

Description

[0001] The invention relates to a security element, in particular for securities, security papers, or security objects, wherein the security element comprises a carrier layer and a motif as a security feature. The invention also relates to a security or security paper, in particular a banknote.

[0002] Security elements of the above-mentioned type are usually used to increase the security against counterfeiting of securities, security papers or security items, such as banknotes, ID cards, credit cards, debit cards, tickets, etc.

[0003] The counterfeit security of motif security features known in the state of the art is usually increased by the fact that the motifs, i.e. images, representations or designs, are particularly detailed, elaborate and complex. However, this only increases counterfeit security if the authenticity of the security, security paper or security object, for example a banknote, is verified by machine or by a specially trained person or even by an expert in the field of counterfeit security. Often, even experts require an aid for authenticity testing, such as a magnifying glass. If a layperson, an untrained person or even an average expert, for example a user of a banknote, attempts to verify the authenticity of the security, security paper or security object, this is not possible or not reliably possible due to the complexity of the motif.

[0004] The object of the present invention is to create a security element with increased security against counterfeiting, which at the same time also increases the design freedom and can be designed in a variety of ways.

[0005] This object is achieved according to the invention by a security element of the type mentioned above in that the motif is divided into several individual motif sections. In other words, the motif is formed from at least two individual motif sections. It is provided that an interruption region is arranged between adjacent motif sections in such a way that a viewer has the impression that the motif is covered by the interruption region or interrupted by the interruption region.

[0006] The inventive design of a security element has the advantage of ensuring particularly high protection against forgery. By dividing comparatively large motifs or overall motifs or overall representations into several individual partial motifs or motif sections, a user is encouraged to look at the motif for longer, allowing them to memorize a representation well and subsequently, in the event of a forgery, be able to recognize it as such and distinguish the original from a forgery. The inventive design of a motif security feature creates an effect that reminds a viewer or user of looking through a keyhole or through a window, for example through the window of a train, car, house, or the like.The human eye is capable of complementing, adding to, or completing the areas of the motif seemingly covered by the overlapping area, such as a window frame. The motif may be comparatively simple or uncomplicated, but its special appearance, or "window look" or "keyhole look," provides a distinctive and highly memorable motif and, thus, a highly counterfeit-proof security feature.

[0007] The security element according to the invention can be designed in any form or configuration known in the prior art. For example, the security element can be a security thread, a security strip, or a security patch. Such security elements are typically applied to or incorporated into a substrate, or onto or into a banknote or other type of security or valuable object. It is also conceivable for the security element to be transferable to a substrate, security, or valuable object by means of a transfer film. Regardless of the form or type of application or insertion, the security element can be used for both paper banknotes and polymer banknotes.

[0008] It is also conceivable for the security element to be directly applied or incorporated into a paper substrate or a polymer substrate, which substrate is subsequently used to produce paper banknotes or polymer banknotes. In particular, it is also conceivable for the security element to be incorporated, in particular embossed, directly into a substrate, in particular directly into a paper or polymer substrate. This means that the security element does not necessarily have to be manufactured separately as a thread, strip, patch or the like, but can also be manufactured directly during substrate production as an integral component. In the case of direct introduction or embossing into the substrate, the carrier layer can already be the paper or polymer substrate. It can also be the case, for example, that the carrier layer is formed as a layer applied to the substrate.

[0009] Furthermore, it may be useful if the interruption area does not show the subject.

[0010] This has the advantage of creating an effect that reminds the viewer or user of looking through a keyhole or window, such as a train window, car window, house window, or similar. For example, the interrupted area can display no motif and be solid-colored, or it can display a different motif. This is particularly effective in encouraging the viewer to memorize the security element.

[0011] It is also conceivable that the interrupted area is at least substantially transparent or translucent. This particularly encourages viewers to memorize the security element.

[0012] Furthermore, it can be provided that the motif represents at least a portrait, a landscape, a building and / or an animal and / or a pattern and / or an abstract geometric sign, logo or an alphanumeric character and / or an icon and / or a symbol and / or a code and / or a sequence of characters. This has the advantage that such particularly memorable representations further contribute to increasing security against counterfeiting.

[0013] Furthermore, it can be provided that the motif is formed by first structures or comprises first structures, wherein the first structures reflect the motif into different spatial areas, so that a moving image is created for the observer upon corresponding movement of a light source, tilting of the security element and / or change of an observation angle.

[0014] This has the advantage that moving images, particularly memorable representations, further increase counterfeit security. This is especially true because a viewer is familiar with, for example, a view out of a window, and is also familiar with the effect that the image or motif viewed through a window also changes, or "wanders," when the viewing angle changes. This makes the motif security feature particularly memorable, and any counterfeits can be reliably identified even by laypeople or untrained individuals.

[0015] Also advantageous is a form of embodiment according to which it can be provided that the moving image is perceptible to the observer as a coherent movement of all motif sections in the event of a corresponding movement of a light source, tilting of the security element and / or a change in the angle of observation.

[0016] This has the advantage that such a movement effect appears particularly familiar to a viewer or appears comparatively real and realistic, so that the motif security feature is particularly memorable and, as a result, the security against counterfeiting is further increased.

[0017] According to a further development, it is possible for the first structures to comprise achromatic and / or reflective structures, such as micromirrors, and / or refractive structures, such as microlenses, and / or diffractive structures, such as holograms.

[0018] This has the advantage of further increasing security against counterfeiting because a high degree of design flexibility is guaranteed.

[0019] Furthermore, it may be expedient if the structures are introduced directly into the carrier layer, in particular embossed by means of a molding device, or wherein the structures are introduced into a further layer, in particular into an embossing lacquer layer, in particular embossed by means of a molding device.

[0020] This has the advantage of further increasing security against counterfeiting because a high degree of design flexibility is guaranteed.

[0021] Furthermore, it can be provided that the motif and / or the interruption area is formed in an optical effect layer.

[0022] Alternatively or additionally, the interrupted area may be formed in an optical effect layer. This may be the same optical effect layer in which the motif is formed. However, it may also be a different or additional optical effect layer.

[0023] This has the advantage of further increasing security against counterfeiting because a high degree of design flexibility is guaranteed.

[0024] According to an advantageous further development, it can be provided that the interruption region is formed by second structures or comprises second structures, wherein the second structures reproduce static and / or viewing angle-independent information.

[0025] This has the advantage of further increasing security against counterfeiting because a high degree of design flexibility is guaranteed.

[0026] In particular, it may be advantageous if a plurality of interruption regions are formed and / or a continuous interruption region, in particular a grid-shaped interruption region, is formed.

[0027] This has the advantage of further increasing counterfeit security because it allows for a high degree of design flexibility. A continuous interrupted area, in particular, can be particularly memorable and, for example, create an effect similar to looking through a window.

[0028] Furthermore, it can be provided that a direct distance between outer edges of motif sections arranged next to one another is between 0.1 mm and 30 mm, preferably between 0.2 mm and 10 mm, particularly preferably between 0.5 mm and 10 mm.

[0029] A direct spacing or a bridge width of this magnitude in the transition area has proven advantageous for creating an appealing and memorable effect and thus a motif security feature with a high level of counterfeit protection. The direct spacing should not be too small to allow for a sufficiently large demarcation between the motif sections, but should also not be too large to maintain a connection between the individual motif sections. The direct spacing between all motif sections may be the same. However, the spacing may also vary.

[0030] Furthermore, it can be provided that the motif sections are arranged in such a way that a further motif is formed by the outer edges of the motif sections arranged on the outside of the motif.

[0031] This has the advantage that the memorability and thus the counterfeit security of the security element is further increased.

[0032] Also advantageous is an embodiment according to which it can be provided that the motif and the interruption region are formed in different layers, or wherein the motif and the interruption region are formed in the same layer.

[0033] This allows for a very wide range of possible layer arrangements, thus ensuring a great deal of design freedom, which can further contribute to increasing security against counterfeiting.

[0034] According to a further development, it is possible for the number of motif sections to be between 2 and 30, preferably between 3 and 20, particularly preferably between 4 and 15.

[0035] A number in these value ranges has proven advantageous in ensuring a high degree of security against counterfeiting, while still making the security feature visually appealing and memorable.

[0036] Furthermore, it may be appropriate if the outer edge of some or all of the motif sections has the same shape, or if the outer edge of all of the motif sections has a different shape.

[0037] This has the advantage of further increasing counterfeit security because it ensures a high degree of design flexibility. If the outer edges of the outer motif cutouts form another motif, for example, the outer edges may also represent the additional motif.

[0038] The motif can be provided in an optical effect layer in the special design of a printed image. For example, a partially opaque printing ink, such as white, and / or a semi-transparent metallization can be used. Among other things, a matte and / or glossy gloss level can be achieved. Alternatively or additionally, the interrupted area can also be provided in an optical effect layer in the special design of a printed image.

[0039] Furthermore, it can be provided that the optical effect layer in which the motif and / or the interruption region is formed is designed as a thin-film element and has at least one absorber layer and at least one spacer layer, or wherein the optical effect layer contains color-shifting pigments, in particular interference pigments, or liquid crystal pigments, or wherein the optical effect layer has metallic pigments and / or magnetic pigments and / or color pigments and / or dyes.

[0040] According to a particular embodiment, it is possible that the optical effect layer is printed and / or vapor-deposited onto the first structures.

[0041] The motif and / or the interruption area, in particular the optical effect layer in which the motif and / or the interruption area is formed, can comprise a metallic effect paint and / or a metallic effect varnish and / or a metallic effect ink and / or a metallic material, in particular selected from the group consisting of silver, copper, aluminum, gold, platinum, niobium, tin, or nickel, titanium, vanadium, chromium, cobalt and palladium or alloys of these materials, in particular cobalt-nickel alloys.

[0042] According to an advantageous further development, it can be provided that the optical effect layer in which the motif and / or the interruption region is formed has a color-shift effect and contains a color-shifting thin-film element or color-shifting pigments, in particular interference pigments, or liquid crystal pigments.

[0043] The optical effect layer can have at least one color-shift effect-enhancing layer on a side facing away from the visible side of the security element, wherein the color-shift effect-enhancing layer is in particular a layer of dark color and / or a layer of metal oxides, such as substoichiometric aluminum oxide. For example, the color-shift effect-enhancing layer can be applied to a liquid crystal layer or a layer of color-shift pigments, such that the layer of color-shift pigments or the liquid crystal layer is arranged between the color-shift effect-enhancing layer and the carrier layer. However, the color-shift effect-enhancing layer can also be arranged between the carrier layer and the layer of color-shift pigments or the at least one liquid crystal layer.In addition, it is also possible that a carrier layer is arranged between the layer enhancing the color-shift effect and the layer of color-shifting pigments or the liquid crystal layer.

[0044] The optical effect layer may comprise at least one liquid crystal layer, in particular a cholesteric liquid crystal layer.

[0045] The optical effect layer can be formed as an optically non-linear layer or as an optically non-linear layer and / or as a layer containing fluorescent pigments and / or fluorescent substances. Optically non-linear layers or layers, or the materials forming this layer, are also referred to as IR upconverters or UV downconverters. These can be materials that exhibit a visible color under the influence of electromagnetic radiation outside the visible wavelength range of light. Such materials can be excited to emit visible light under these conditions, for example upon irradiation with infrared (IR) (λ > 780 nm) and / or ultraviolet (UV) light (λ < 380 nm).

[0046] The described first or second structures can be introduced directly into the carrier layer or into a further layer, in particular an embossing lacquer layer, in particular embossed by means of a molding device. The structure or structures can be embossed directly into a carrier layer. For example, by heating the carrier layer and embossing the structures using an embossing tool, such as an embossing roller. Another alternative possibility would be to provide a separate further layer to accommodate the structures. The further layer can be applied directly to a carrier layer. For example, the further layer can be formed from an embossing lacquer which is shaped to match the arrangement of the structures. This can in turn be done by means of a molding device or a molding element in an embossing process.

[0047] The arrangement or application of the optical effect layer onto the structures or the metal layers and / or metal effect layers can be carried out, for example, by a printing process and / or a vapor deposition process or several of these. However, the materials or additives of the reflection layer described below could also form a component or layer of the optical effect layer. These can, in particular, be printed or vapor deposited and thus form a separate layer of the optical effect layer. In particular, it can be advantageous if the optical effect layer is designed as a thin-film element and has at least one absorber layer and at least one spacer layer.

[0048] The at least one absorber layer may comprise at least one metallic material, in particular selected from the group of nickel, titanium, vanadium, chromium, cobalt, palladium, iron, tungsten, molybdenum, niobium, aluminum, silver, copper and / or alloys of these materials, or may be made of at least one of these materials.

[0049] Furthermore, it can be provided that the optical effect layer formed as a thin-film element further comprises at least one reflection layer and / or a second absorber layer, wherein the at least one spacer layer is arranged between the at least one first absorber layer and the at least one reflection layer and / or the at least one second absorber layer.

[0050] The reflective layer can be applied or arranged on structures, and in particular, can be printed and / or vapor-deposited onto them. It is also possible to reverse this order in the optical effect layer, so that the absorber layer is arranged on the structures, followed by the spacer layer and the reflective layer. Thus, the arrangement would be in the order structures – absorber layer – spacer layer – reflective layer. However, an additional absorber layer can also be provided instead of the aforementioned reflective layer.

[0051] The at least one reflective layer can comprise at least one metallic material, in particular selected from the group consisting of silver, copper, aluminum, gold, platinum, niobium, tin, or nickel, titanium, vanadium, chromium, cobalt and palladium or alloys of these materials, in particular cobalt-nickel alloys or at least one high-index dielectric material with a refractive index greater than 1.65, in particular selected from the group consisting of zinc sulfide (ZnS), zinc oxide (ZnO), titanium dioxide (TiO 2 ), carbon (C), indium oxide (In 2 O 3 ), indium tin oxide (ITO), tantalum pentoxide (Ta 2 O 5 ), cerium oxide (CeO 2 ), yttrium oxide (Y 2 O 3 ), europium oxide (Eu 2 O 3 ), iron oxides such as iron(II,III) oxide (Fe 3 O 4 ) and iron(III) oxide (Fe 2 O 3 ), Hafnium nitride (HfN), hafnium carbide (HfC), hafnium oxide (HfO 2 ), lanthanum oxide (La 2 O 3 ), magnesium oxide (MgO), neodymium oxide (Nd 2 O 3 ), praseodymium oxide (Pr 6 O 11 ), samarium oxide (Sm 2 O 3 ), antimony trioxide (Sb 2 O 3 ), silicon carbide (SiC),Silicon nitride (Si 3 N 4 ), silicon monoxide (SiO), selenium trioxide (Se 2 O 3 ), tin oxide (SnO 2 ), tungsten trioxide (WO 3 ), high-index organic monomers and / or high-index organic polymers or be made from at least one of these materials.

[0052] The at least one spacer layer can be a low-refractive dielectric material with a refractive index less than or equal to 1.65, in particular selected from the group aluminum oxide (Al 2 O 3 ), metal fluorides, for example magnesium fluoride (MgF 2 ), aluminum fluoride (AlF 3 ), cerium fluoride (CeF 3 ), sodium aluminum fluorides (e.g. Na 3 AlF 6 or Na 5 Al 3 F 14 ), silicon oxide (SiO x ), silicon dioxide (SiO 2 ), neodymium fluoride (NdF 3 ), lanthanum fluoride (LaF 3 ), samarium fluoride (SmF 3 ), barium fluoride (BaF 2 ), calcium fluoride (CaF 2 ), lithium fluoride (LiF), low-refractive organic monomers and / or low-refractive organic polymers or at least one high-refractive dielectric material with a refractive index greater than 1.65, in particular selected from the group zinc sulfide (ZnS), zinc oxide (ZnO), titanium dioxide (TiO 2 ), carbon (C), indium oxide (In 2 O 3 ), indium tin oxide (ITO), tantalum pentoxide (Ta 2 O 5 ), cerium oxide (CeO 2 ), yttrium oxide (Y 2 O 3 ),Europium oxide (Eu 2 O 3 ), iron oxides such as iron(II,III) oxide (Fe 3 O 4 ) and iron(III) oxide (Fe 2 O 3 ), hafnium nitride (HfN), hafnium carbide (HfC), hafnium oxide (HfO 2 ), lanthanum oxide (La 2 O 3 ), magnesium oxide (MgO), neodymium oxide (Nd 2 O 3 ), praseodymium oxide (Pr 6 O 11 ), samarium oxide (Sm 2 O 3 ), antimony trioxide (Sb 2 O 3 ), silicon carbide (SiC), silicon nitride (Si 3 N 4 ), silicon monoxide (SiO), selenium trioxide (Se 2 O 3 ), tin oxide (SnO 2 ), tungsten trioxide (WO 3 ), high-index organic monomers and / or high-index organic polymers or comprise at least one of these materials be manufactured.,

[0053] Furthermore, it can be provided that the optical effect layer is a partial layer or comprises a partial layer, wherein the motif is represented by the partial layer.

[0054] The security element comprises a carrier layer, in particular a carrier film, made of a plastic, wherein in particular the plastic can be formed from a translucent and / or thermoplastic plastic. The carrier layer can preferably contain at least one of the materials from the group polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene (MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyetherketone (PEK), polyethyleneimide (PEI), polysulfone (PSU), polyaryletherketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), ethylenetetrafluoroethylene (ETFE), polytetrafluoroethylene (PTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF),Ethylene tetrafluoroethylene hexafluoropropylene fluoro terpolymer (EFEP), cellulose- or lignin-based plastics, polyhydroxyalkanoates (PHA), thermoplastic starch (TPS), polylactic acid (PLA), polycaprolactone (PCL), polybutylene succinate (PBS), and polybutylene adipate terephthalate (PBAT) and / or at least one recycled and / or biodegradable and / or marine degradable plastic and / or mixtures and / or copolymers of these materials or be made from at least one of these materials.

[0055] As is known per se, the security element can have additional layers, which additional layers include, in particular, protective varnishes, heat-sealing varnishes, adhesives, primers, and / or foils. Protective varnishes can protect the entire layer and / or layer structure from mechanical damage such as scratches, scoring, or the like. A protective layer can be provided on one or both sides. Preferably, a planar design of the security element can also be achieved using a protective layer.

[0056] The object of the invention is also achieved by a security paper or security document, in particular a banknote, which comprises a security element according to one of the claims or according to the above description. Alternatively or additionally, the security paper or security document comprises a substrate with a security element according to one of the claims or according to the above description.

[0057] The inventive design of a security document or security paper has the advantage of ensuring particularly high protection against forgery. By dividing comparatively large motifs or overall motifs or overall representations into several individual partial motifs or motif sections, a user is encouraged to look at the motif for longer, allowing them to memorize a representation well and subsequently, in the event of a forgery, be able to recognize it as such and distinguish the original from a forgery. The inventive design of a motif security feature creates an effect that reminds a viewer or user of looking through a keyhole or through a window, for example through the window of a train, car, house, or the like.The human eye is capable of complementing, adding to, or completing the areas of the motif seemingly covered by the overlapping area, such as a window frame. The motif may be comparatively simple or uncomplicated, but its special appearance, or "window look" or "keyhole look," provides a distinctive and highly memorable motif and, thus, a highly counterfeit-proof security feature.

[0058] To avoid unnecessary repetition, please refer to the previous descriptions of the training courses and benefits.

[0059] For a better understanding of the invention, it is explained in more detail with reference to the following figures.

[0060] They show in a highly simplified, schematic representation: Fig. 1 shows an embodiment of a security element in plan view, Fig. 2 shows a tilted view of the security element from Fig. 1 , Fig. 3 another tilted view of the security element from Fig. 1 , Fig. 4 a further embodiment of a security element in plan view, Fig. 5 a possible layer structure of the security element from Fig. 4 in sectional view, Fig. 6 a further embodiment of a security element in plan view, Fig. 7 a tilted view of the security element from Fig. 6 , Fig. 8 another tilted view of the security element from Fig. 6 .

[0061] By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations, whereby the disclosures contained in the entire description can be applied mutatis mutandis to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure, and in the event of a change in position, these positional information must be applied mutatis mutandis to the new position.

[0062] By way of introduction, it should be mentioned that the layer structure, as well as the arrangement of further layers, depends on the type of attachment of the security element to a security object, since the side of the security element to be viewed after attachment is crucial. Thus, the visible side can be viewed from above, as shown in the figures, but it is also possible to view the security element from below, e.g., through a support.

[0063] At this point, it should be noted that the phrase "a layer is applied to something" should be understood to mean that the layer can be applied directly, or that one or more intermediate layers can be located between the applied layer and the material to which the layer is applied. It should also be noted that one or more intermediate layers can be arranged between the layers described in this document. It is therefore not absolutely necessary for the described layers to contact one another. Furthermore, it should be noted that the term "layer" in this document should be understood to mean that a layer can also be composed of several sublayers.

[0064] The figures show exemplary embodiments of security elements 1 in plan view and in sectional view to illustrate conceivable layer structures. The exemplary embodiments are described below in summary to avoid unnecessary repetition. It goes without saying, and is evident from the advantageous developments described above, that the exemplary embodiments described below are merely exemplary and, in particular, are by no means to be understood as preferred or even exhaustive.

[0065] In the Fig. 1 to Fig. 3 An embodiment of a security element 1 in the special design of a security thread is shown. Fig. 6 to Fig. 8 Another embodiment of a security element 1 is shown in the special design of a security thread. The other embodiment according to the Figs. 4 and 5For example, a security element 1 can be in the form of a patch or the like. Alternatively, it could also be designed as a security strip, transfer element, overlay, or the like. Likewise, the security element 1 can be formed directly in a polymer substrate for the production of polymer banknotes or directly in a paper substrate for the production of paper banknotes, i.e., it can be introduced directly into a substrate, in particular embossed into a substrate. The security element 1 for securities, security papers, or security articles each comprises a carrier layer 2 and a motif 3 as a security feature. The carrier layer 2 or a conceivable layer structure of a security element 1 is described below using the sectional view according to Fig. 5described in more detail. The two security elements 1 shown as examples can be arranged in or on a security or security paper, in particular also in or on the substrate for a security or security paper. In addition to the security feature designed as motif 3, other security features of the same or different types can of course also be provided. A thread according to Fig. 1 to 3 , as well as Fig. 6 to 8 , or a patch according to Fig. 4 The security element 1 formed can be incorporated into a banknote substrate during the production of a security document or security paper.

[0066] The motif 3 can represent at least a portrait, a landscape, a building and / or an animal and / or a pattern and / or an abstract geometric character, logo or an alphanumeric character and / or an icon and / or a symbol and / or a code and / or a sequence of characters. In the embodiment according to the Fig. 1 to Fig. 3 , as well as in accordance with the Fig. 6 to Fig. 8 Motif 3 is a skyline of high-rise buildings and therefore reminds the viewer of the view through a window or through several windows. In the embodiment according to the Fig. 4 to Fig. 5 Motif 3 is a landscape. It goes without saying that these depictions are merely examples of a multitude of conceivable motifs.

[0067] In both embodiments, the motif 3 or overall motif is divided into several individual motif sections 4, with an interrupted area 5 being arranged between adjacent motif sections 4 in such a way that a viewer has the impression that the motif 3 is covered or interrupted by the interrupted area 5. It is possible that the interrupted area 5 does not show the respective motif 3.

[0068] Furthermore, the interruption region 5 may be at least substantially transparent or translucent.

[0069] It may be that the motif 3 is formed by first structures 6 or comprises first structures 6, wherein the first structures 6 reflect the motif 3 into different spatial areas, so that a moving image is created for the observer upon corresponding movement of a light source, tilting of the security element 1 and / or change of an observation angle.

[0070] Such a movement picture is in a synopsis of the Fig. 1 to Fig. 3 illustrated. The Fig. 1 The double arrow shown indicates two tilt directions 16 of the security element 1. The Fig. 2 shows a possible view of the motif 3 after tilting in one of the two tilting directions 16 and the Fig. 3 shows a possible view of the motif 3 after tilting in the other of the two tilt directions 16.

[0071] Another example of a motion picture is shown in a summary of the Fig. 6 to Fig. 8 illustrated. The Fig. 6The double arrow shown indicates two tilt directions 16 of the security element 1. The Fig. 7 shows a possible view of the motif 3 after tilting in one of the two tilting directions 16 and the Fig. 8 shows a possible view of the motif 3 after tilting in the other of the two tilt directions 16.

[0072] While the movement pattern in the exemplary embodiment is according to the Fig. 1 to 3 perspective shifts, i.e. the static three-dimensional view shifts, the movement image in the embodiment changes according to the Fig. 6 to 8 by shifting or displacing the motif or the shown skyline in the respective tilt direction 16 relative to the frame.

[0073] It may be that the moving image is perceptible to the observer as a coherent movement of all motif sections 4 when a light source moves accordingly, when the security element 1 is tilted and / or when an observation angle is changed.

[0074] It may be that several interruption areas 5 are formed. However, it may also be that, as in the Fig. 1 to 3 and Fig. 4 , as well as in the Fig. 6 to 8 shown, a continuous interruption region 5, in particular a grid-shaped interruption region 5, is formed. In the example according to the Fig. 1 to 3 , as well as in the example according to the Fig. 6 to 8 the entire visible side 18 of the security thread is covered by the motif 3, or by the motif cutouts 4, as well as by the grid-like or window cross-like interruption area 5. In the example according to Fig. 4Another area is shown, which has an additional security feature. This is represented as an additional motif, exemplified by a multitude of circles.

[0075] It may be that a direct distance 8 between outer edges 9 of adjacently arranged motif sections 4 is between 0.1 mm and 30 mm, preferably between 0.2 mm and 10 mm, particularly preferably between 0.5 mm and 10 mm. In the example according to Fig. 1 to 3 , as well as in the example according to the Fig. 6 to 8 The distances 8 between outer edges 9 of adjacent motif sections 4 are each different. In the example according to Fig. 4 the distances 8 between outer edges 9 of motif sections 4 arranged next to one another are constant or equal.

[0076] It may be that the motif sections 4 are arranged in such a way that a further motif 10 is formed by the outer edges 9 of the motif sections 4 arranged on the outside in the motif 3. In the Fig. 4 For example, it is shown that the outer edges 9 of the motif sections 4 arranged on the outside in the motif 3 form a further motif 10 in the shape of a star.

[0077] It may be that the number of motif sections 4 is between 2 and 30, preferably between 3 and 20, particularly preferably between 4 and 15.

[0078] It may be that the outer edge 9 of some or all of the motif sections 4 has the same shape, or the outer edge 9 of all motif sections 4 has a different shape. In the example according to the Fig. 1 to 3 , as well as in the example according to the Fig. 6 to 8 All outer edges 9 of the motif sections 4 have a rectangular shape, but are of different sizes. In the example according to Fig. 4a centrally arranged motif section 4 has a hexagonal shape or contour, and the six outer motif sections 4, which form the tips of the star shown as a further motif 10, each have a triangular shape or contour.

[0079] Fig. 5 shows a sectional view of the embodiment according to Fig. 4and thereby a conceivable layer structure of a security element 1. This, in turn, is shown in a highly simplified manner and is representative of a multitude of possible layer structures. Although the motif 3 and the interrupted region 5 are arranged in such a way that a viewer has the impression that the motif 3 is covered or interrupted by the interrupted region 5, it is not absolutely necessary - although of course equally possible and advantageous - that the interrupted region 5 is actually on top or above the motif 3 when the security element 1 is viewed from its upper side or visible side 18 and could therefore actually cover it. It is therefore possible that the motif 3 and the interrupted region 5 are formed in different layers, or that the motif 3 and the interrupted region 5 are formed in the same layer.The interruption region 5 can, for example, be formed in a layer which, when viewed from the visible side 18, lies below the motif 3 or lies below the layer in which the motif 3 is formed. The interruption region 5 can, for example, also be formed in a layer which, when viewed from the visible side 18, lies above the motif 3 or lies above the layer in which the motif 3 is formed. The interruption region 5 can be designed as a print. As already described, the interruption region 5 can also be transparent or translucent. As in the . Fig. 5 It can also be shown that the interruption region 5 and the motif 3 are formed in the same layer, in particular in the same embossing lacquer layer 13.

[0080] As described above, the security element 1 has a carrier layer 2 or a carrier film. As explained above, this can be a plastic film, for example a PET film. On one side thereof, for example on its underside or on the side facing away from the visible side 18, a primer 11 can be applied, and on the primer 11, as the outermost layer of the arrangement, a heat-sealing lacquer 12 can be arranged, which protects the layer structure. With this heat-sealing lacquer 12, as is known per se, an application of the security element 1 to a security document can be carried out or facilitated. On the second side of the carrier layer 2, for example on the top side or on a side facing the visible side 18 of the security element 1, an embossing lacquer layer 13 can be applied, into which embossing lacquer layer 13 first structures 6 are embossed. These first structures 6 can form the motif 3.

[0081] It may also be the case that the first structures 6 comprise achromatic and / or reflective structures, in particular micromirrors, and / or refractive structures, in particular microlenses, and / or diffractive structures, in particular holograms. It may also be the case that the motif 3 and / or the interruption region 5 is formed in an optical effect layer. On the first structures 6, as shown in the Fig. 5 For example, as shown, a reflection layer 14 may be applied, for example a metallized layer of aluminum.

[0082] It may also be the case that the interruption region 5 is formed by second structures 17 or comprises second structures 17, wherein the second structures 17 reproduce static and / or viewing angle-independent information. These second structures 17 may be formed as shown in the Fig. 5outlined, also be introduced or embossed into the embossing lacquer layer 13. On the second structures 17, as in the Fig. 5 For example, as shown, a further reflection layer 15 may be applied, for example a metallized layer of copper.

[0083] The embodiments show possible embodiments, whereby it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments with one another are also possible and this possibility of variation lies within the skill of the person skilled in the art in this technical field due to the teaching of technical action by means of the objective invention.

[0084] The scope of protection is determined by the claims. However, the description and drawings must be used to interpret the claims. Individual features or combinations of features from the various embodiments shown and described may represent independent inventive solutions. The problem underlying the independent inventive solutions can be derived from the description.

[0085] All information on value ranges in this description is to be understood as including any and all sub-ranges thereof, e.g. the information 1 to 10 is to be understood as including all sub-ranges starting from the lower limit of 1 and the upper limit of 10, ie all sub-ranges begin with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

[0086] For the sake of clarity, it should finally be pointed out that, in order to better understand the structure, some elements have been shown out of scale and / or enlarged and / or reduced in size. Reference symbol list
