Security element transfer material for transferring security elements having micro-optical authenticity features and method for manufacturing same

Abstract

The invention relates to a security element transfer material (1) for transferring security elements (4) having a micro-optical authenticity feature to an item of value (5, 30). The micro-optical authenticity feature produces an optical effect by the cooperation of a first micro-optical arrangement (11) with focusing elements (12, e.g. Microlenses) and a second micro-optical arrangement (13) with micro-visual object elements (14). The security element transfer material (1) has a temporary carrier (3) in the form of a layer composite material. The temporary carrier consists of a first temporary carrier substrate (31, 34) and a second temporary carrier substrate (32) which can be non-releasably bonded by means of an adhesive layer (33). According to the invention, the contour shape of the security element to be transferred is cut (8) or pre-cut (8), and the second temporary carrier substrate (32) is not cut open, so that the temporary carrier can be separated as a complete carrier layer composite (Figure 3i, 4g, 5h). The permanent carrier (15) is non-releasably connected to the microlenses. The transfer glue (18) enables adhesion to the final substrate (30) of the valuable article.

Description

[0001] The present invention relates to a security element transfer material, which is used to transfer a security element with a micro-optical authenticity feature to a valuable item, such as a valuable document, security paper or branded goods. The present invention also relates to a method for manufacturing the security element transfer material, a method for authenticity marking of a valuable item, such as a valuable document, security paper or branded goods, by means of a micro-optical authenticity feature, and a valuable item, such as a valuable document, security paper or branded goods, which is protected from counterfeiting using the security element transfer material.

[0002] Valuable items, such as valuable documents, identity documents, banknotes, certificates, checks, and other valuable items, such as branded goods, and original products of valuable documents, such as security papers, are usually equipped with security elements for anti-counterfeiting, which enable the authenticity of the valuable items to be verified and are used to prevent unauthorized copying. The security element can be designed, for example, as a security thread embedded in the banknote, a cover film for banknotes with continuous openings, an applied security strip or a self-supporting film security element, such as a label, which is applied to the valuable document after its production.

[0003] The special function of the security element here is to give the observer a different image impression at different viewing angles, since even the highest-quality color copying equipment cannot reproduce such a security element. For example, it is known to equip security elements with security features in the form of diffractive optical effect microstructures or nanostructures, such as relief holograms or other hologram-like diffractive structures.

[0004] It is also known to use focusing structures such as lens systems as security features. For example, patent document EP 0 238 043 A2 discloses a security thread made of a transparent material, the surface of which is embossed with a grid made of a plurality of cylindrical lenses extending in parallel. The thickness of the security thread is selected to correspond approximately to the focal length of the cylindrical lenses. The printed image is applied in register to the opposing surface, wherein the printed image is designed taking into account the optical properties of the cylindrical lenses.

[0005] Other micro-optical authenticity features are so-called moiré magnification arrangements, known, for example, from patent document WO 2006 / 087138 A1. The security element disclosed in this patent document has at least one first and one second authenticity feature. The first authenticity feature comprises a first arrangement having a plurality of focusing elements present in a first grid and a second arrangement having a plurality of microstructures present in a second grid. The first arrangement and the second arrangement are arranged relative to one another in such a way that the microstructures of the second arrangement can be seen magnified when viewed through the focusing elements of the first arrangement.

[0006] The article "The moiré magnifier", MC Hutley, R. Hunt, RF Stevens and P. Savander, Pure Appl. Opt. 3 (1994), pp. 133-142, describes the working principle of such a moiré magnification arrangement. In short, moiré magnification refers to the phenomenon that occurs when a grid of the same image object is viewed through a lenticular grid with approximately the same grid dimensions. As with any pair of similar grids, moiré patterns are produced here, which in this case are magnified and possibly rotated images of the repeating elements of the image grid.

[0007] The focusing elements of the micro-optical authenticity features are usually embossed in embossing lacquer. The microstructures to be observed through the focusing elements can in principle be produced in any manner and have any shape. In order to be able to identify the complete microstructures respectively through the focusing elements, usually microlenses, the microlenses and microstructures must have approximately the same size class. In addition, the closer the microstructures are to the focal point of the lens, the greater the magnification effect of the microlens. Since the greater the curvature of the lens, the smaller the focal length, in order to achieve good magnification, either the distance between the lens and the microstructure must be larger (in the case of a smaller curvature of the lens) or a lens with a larger curvature must be used (in the case of a smaller distance between the lens and the microstructure).

[0008] Since embossing lacquers suitable for embossing microfocusing elements are expensive, it is desirable to use embossing lacquer layers that are as thin as possible. However, thin embossing lacquer layers impose restrictions on the focusing structures that can be formed. For example, with the same lens diameter, only lenses with a smaller lens curvature can be formed in a thin embossing lacquer layer than in a thick embossing lacquer layer. A smaller lens curvature in turn requires a greater distance from the microstructure to be observed.

[0009] From the perspective of anti-counterfeiting, it is also advantageous to ensure that lenses or other focusing structures cannot be copied. Exposed focusing structures should be avoided as much as possible, i.e., they should be provided with a protective layer if necessary.

[0010] Security element is not provided separately usually, but for example provides in the form of the transfer tape of the security element that has a plurality of designs as transfer element.The characteristics of transfer tape are, prepare security element on carrier layer, wherein, the order of the layer of transfer element should be opposite to the order that exists on the valuable item to be protected afterwards.When transferring, usually remove the carrier layer from the layer structure of security element.On the side opposite to carrier layer, transfer tape has the glue layer that is usually made of heat seal adhesive, and this glue layer melts when transferring security element, and security element is bonded with the valuable item to be anti-counterfeited.The transfer tape with heat seal adhesive layer is placed on the valuable item, and is pressed and transferred to the valuable item according to the profile shape of the transfer punch of heating by means of heated transfer punch or transfer roller.For example, transfer element, transfer tape and transfer element are transferred to the target substrate in patent documentation EP 0 420 261 B1 and WO 2005 / 108108 A2.

[0011] Particularly challenging is the provision of a film security element, i.e. a security element with micro-optical authenticity features in the form of a security element transfer material, which comprises a permanent carrier substrate in its layer structure. A permanent carrier substrate such as a plastic film has the advantage that the security element is stable so that the security element can be used, for example, to close a continuous opening in a value document. On the other hand, the permanent carrier substrate prevents the security element layer structure from being easily cut during the transfer process from the security element transfer material to the value document. Therefore, the security element comprising a permanent carrier substrate in its layer structure must be present as a prefabricated individual element on the transfer material, which means that the contour shape of the security element must be precut into the security element material. The precutting can be performed, for example, by means of a laser.

[0012] The problem that arises here is that the cutting depth must be controlled very precisely in order to cut through the entire layer structure of the security element on the one hand, but on the other hand not to damage the carrier material removed during the transfer process. This is extremely difficult because the layer structure of the security element usually has a thickness in the range of only about 20 μm to 30 μm, while the carrier film has a thickness in the range of about 10 μm to 30 μm.

[0013] Plastic films are usually used as carrier materials. Although plastic films have high tear resistance, they have low tear propagation resistance. Therefore, when the carrier material is cut, it is almost inevitable that the security element transfer material, which exists as a continuous material, will tear at some locations during the process of transferring the security element to the valuable article. On the other hand, if the layer structure of the security element is not completely cut off, the security element may be damaged during the transfer, resulting in the observed optical effect being adversely affected. In the worst case, the security element transferred to the valuable article is completely unusable.

[0014] To date, there has been no security element transfer material which carries a security element which has micro-optical authenticity features that can be produced precisely and cost-effectively and which has a stable carrier film in its layer structure but can nevertheless be transferred smoothly to a valuable document, i.e. without the risk of damaging the micro-optical features and without the risk of tearing the temporary carrier material.

[0015] Therefore, the technical problem to be solved by the present invention is to provide such a security element transfer material and a method for producing the security element transfer material. In order to improve the anti-counterfeiting property, the focusing elements of the security element are preferably not contourable (molded). These focusing elements should also preferably be protected from wear and dirt, because if the focusing elements are dirty or worn, the perfect visibility of the optical effect can no longer be guaranteed.

[0016] Another object of the present invention is to provide a method for authenticity verification of valuable articles by transferring a security element having a stable carrier film, wherein the authenticity verification is performed by means of micro-optical authenticity features.

[0017] Another technical problem to be solved by the present invention is to provide a valuable article having a micro-optical authenticity feature for authenticity verification.

[0018] The above technical problem is solved by a method for producing a security element transfer material having the features of independent claims 1, 2 and 4. The security element transfer material, the method for authenticity identification of a valuable article and the valuable article are given in the parallel claims. The expanded design of the invention is the technical solution of the dependent claims.

[0019] According to a first embodiment of the present invention, a first micro-optical arrangement structure is manufactured as follows: an embossing lacquer having (a) a high refractive index or (b) a low refractive index is applied to a permanent carrier substrate or a temporary carrier, a focusing structure, in particular a microlens structure, is embossed in the embossing lacquer, and the temporary carrier or the permanent carrier substrate is bonded by means of an adhesive lacquer, wherein in case (a) an adhesive lacquer having a low refractive index is used and in case (b) an adhesive lacquer having a high refractive index is used.

[0020] As a temporary carrier, the multilayer carrier disclosed in patent document WO 2010 / 031543 A1 can be used, wherein the carrier is preferably not used as a finished carrier composite, but is produced during the production process of the security element transfer material.

[0021] In this first embodiment, the interface between the lacquer with a high refractive index and the lacquer with a low refractive index creates a precise focusing element. Since the focusing element is located inside the double-layer lacquer and cannot be contoured, the micro-optic authenticity feature is particularly resistant to counterfeiting and is protected against wear and dirt.

[0022] The second micro-optical arrangement with the micro-optical object elements is preferably formed by printing on the surface of the permanent carrier substrate facing away from the first micro-optical arrangement. However, the production of the second micro-optical arrangement is not limited and can be produced in any manner known to those skilled in the art, such as embossing.

[0023] The first embodiment of producing the security element transfer material according to the present invention includes two variants, which are shown in FIGS. 3 and 4 and will be explained in detail in conjunction with the description of these figures.

[0024] Independent claims 1 and 2 claim protection of a method according to the present invention for manufacturing security element transfer materials according to two variants of the first embodiment, independent claims 7 and 8 claim protection of security element transfer materials according to the present invention according to two variants of the first embodiment, and independent claim 12 claims protection of a method according to the present invention for authenticity marking of valuable items including two variants of the first embodiment.

[0025] According to a second embodiment of the present invention, the first micro-optical arrangement structure is manufactured as follows: embossing lacquer is applied to a temporary carrier substrate (a) or a permanent carrier substrate (b), a focusing structure, especially a microlens structure, is embossed in the embossing lacquer, and the permanent carrier substrate in case (a) or the temporary carrier substrate in case (b) is bonded by means of an adhesive lacquer.

[0026] In a second embodiment, the focusing element consists of a focusing structure embossed in the embossing lacquer or a complementary structure produced in the bonding lacquer.

[0027] When transferring the security element to the value document, one of the two lacquer layers, namely the embossing lacquer layer or the adhesive lacquer layer, is removed together with the temporary carrier, ie forms part of the temporary carrier.

[0028] As disclosed in WO 2010 / 031543 A1, a single plastic film or a carrier layer composite can be used as temporary carrier substrate.

[0029] The second micro-optical arrangement is formed on a surface of the permanent carrier substrate remote from the first micro-optical arrangement.

[0030] FIG5 shows a method for producing a security element transfer material according to a second embodiment according to the present invention, and is explained in detail in conjunction with the description of this figure.

[0031] Independent claim 5 claims protection for a method according to the present invention for manufacturing a security element transfer material according to the second embodiment, independent claim 10 claims protection for a security element transfer material according to the second embodiment according to the present invention, and independent claim 12 claims protection for a method according to the present invention for authenticity marking of valuable items including the second embodiment.

[0032] According to a third embodiment of the invention, the security element of the security element transfer material contains only the first micro-optic arrangement of the micro-optic authenticity feature, while the second micro-optic arrangement is formed on the valuable article itself.

[0033] In a third embodiment of the present invention, the first micro-optical arrangement can be produced according to both variants of the first embodiment or according to the second embodiment.

[0035] Independent claims 13 and 14 claim protection for a method for authenticity marking of a valuable object according to a third embodiment of the invention.

[0036] The invention is explained below with reference to the accompanying drawings. The illustrated embodiments are to be understood as purely illustrative and not restrictive. For the sake of clarity, the drawings are not shown in true size and true proportion. Only the basic elements important for understanding the relevant embodiments are shown. In fact, the anti-counterfeiting element has not only the layers or layer sequences shown respectively, but also additional functional layers and / or auxiliary layers. Since they are not important for understanding the embodiments of the invention and belong to the knowledge of ordinary technicians in this field, they are not explicitly shown in the drawings. The same or corresponding elements are marked with the same reference numerals in the drawings.

[0045] Figure 1 The top view shows a value document 5 having a security element 4 transferred thereto from a security element transfer material 1 according to the invention. The embodiment shown is a banknote which, in addition to the security element 4 according to the invention, has a further security element, namely a security thread 4 ″.

[0046] The security element 4 according to the invention is a film patch which closes the continuous opening 9 of the value document. Also shown are micro-visual object elements (or micro-motif elements) 14 and micro-visual object elements 14', which will be explained in more detail below.

[0047] Figure 2 A top view shows a security element transfer material 1 according to the invention, in which the security elements are precut. The security element 4 has a contour shape 7 and is surrounded by an area 6 from which the security element layer composite material has been removed. Figure 2 The security element transfer material 1 according to the invention is shown as a continuous strip, wherein only one security element is present in each case along the width direction. In practice, the continuous strip can be wider and comprise a plurality of adjacently arranged security elements.

[0048] Figures 3a to 3i Along the Figure 2The sectional view taken along line AA' of shows the method stages of manufacturing the security element transfer material 1 according to the first embodiment, variant 1 of the present invention, and transferring the security element 4 from the security element transfer material to a valuable article.

[0049] First, if Figure 3a As shown, a layer of embossing lacquer 20 with a high refractive index is applied to an embossing film 31, and focusing structures 10, such as convex microlenses, are embossed in the embossing lacquer layer 20. The embossing film 31 forms part of a temporary carrier 3, which is removed from the security element when the security element is transferred to a valuable object, i.e., is only used "temporarily" as a carrier for the security element.

[0050] Afterwards, if Figure 3b As shown, the film 15 is bonded to the embossing lacquer layer 20 by means of an adhesive lacquer 23 having a low refractive index. The adhesive lacquer must have a sufficiently low viscosity so that it fully adapts to the focusing structure 10, that is, forms a completely complementary structure at the interface with the focusing structure 10. Interface 26 ( Figure 3e ) constitutes a focusing element 12 of the first micro-optical arrangement structure.

[0051] Alternatively, Figure 3c As shown, a layer of embossing lacquer 21 with a low refractive index is applied to the embossing film 15, and focusing structures 19, for example concave microlenses, are embossed in inverted form in the embossing lacquer layer 21. The embossing film 15 is a permanent carrier substrate for the security element 4 to be transferred, i.e. a film which permanently remains in the security element layer composite as a stabilizing element.

[0052] Afterwards, if Figure 3d As shown, the film 31 is glued to the embossing lacquer layer 21 by means of an adhesive lacquer 22 having a high refractive index. The adhesive lacquer must have a sufficiently low viscosity so that it is fully adapted to the inverted embossed focusing structure 19, i.e., forms a completely complementary structure at the interface with the structure 19. Interface 26 ( Figure 3e ) constitutes a focusing element 12 of the first micro-optical arrangement structure.

[0053] The focusing structure 10 or the inverted (reverse) focusing structure 19 must of course be cured before bonding.

[0054] like Figure 3eAs shown, in both methods, a first micro-optical arrangement 11 with micro-focusing elements 12 is obtained, which is formed by an interface 26 with a focusing structure between a lacquer layer with a high refractive index and a lacquer layer with a low refractive index. The first micro-optical arrangement 11 is located between films 15 and 31, which form a part of a permanent carrier substrate or a temporary carrier 3 of the security element. Subsequently, a support film, i.e., a second temporary carrier substrate 32, is glued to the temporary carrier substrate 31 by means of an adhesive 33, so that the temporary carrier 3 is completed, and the adhesive connects the temporary carrier substrate 31 to the temporary carrier substrate 32 in an undetachable manner.

[0055] like Figure 3f As shown, in order to produce the micro-optical authenticity feature, a second micro-optical arrangement 13 is produced on the surface of the permanent carrier substrate 15 remote from the temporary carrier 3 and the first micro-optical arrangement 11. The second micro-optical arrangement 13 has micro-vision object elements 14, which together with the micro-focusing elements 12 form, for example, a moiré magnification arrangement, or produce a tilted image or other optical effects.

[0056] The bonding lacquer layer advantageously has just such a thickness that recesses or gaps in the embossing structure of the embossing lacquer layer are completely filled, so that the interface with the attached permanent carrier substrate or the attached temporary carrier substrate is completely planar.

[0057] The thickness of the permanent carrier substrate 15 and the thickness of the adjoining lacquer layer with a low refractive index must be adapted to the geometry of the microfocusing element 12, so that the focal length of the microfocusing element 12 and the position of the micro-optical object element 14 must be adapted to one another so that the desired optical effect can be observed. Since the required lacquers are very expensive, it is advantageous to use lacquer layers that are as thin as possible and to ensure the required distance to the second micro-optical arrangement 13 by selecting a thicker (less expensive) permanent carrier substrate 15.

[0058] In order to bond the security element 4 to be transferred to the valuable object to be protected from counterfeiting, a transfer adhesive layer 18 is applied as the last layer, which usually consists of a heat-sealing lacquer. Figure 3g In the view of FIG. 1 , a primer layer 17 is provided to improve the adhesion between the transfer adhesive layer 18 and the second micro-optical arrangement 13. The first micro-optical arrangement 11, the permanent carrier substrate 15, the second micro-optical arrangement 13, the optional primer layer 17 and the transfer adhesive layer 18 constitute the security element layer composite 2, and the first temporary carrier substrate 31, the second temporary carrier substrate 32 and the adhesive layer 33 that non-detachably connects the two temporary carrier substrates to each other constitute the carrier layer composite of the temporary carrier 3.

[0059] Figure 3gThe contour shape 7 of the subsequent security element 4 is cut into the security element layer composite 2, for example by means of a laser (see Figure 2 ) after the security element transfer material 1. The cut is shown as a line 8. The cut 8 not only cuts through the security element layer composite 2, but also partially cuts through the first temporary carrier substrate 31. The cut may also reach into the glue layer 33.

[0060] In principle, the security element transfer material 1 can be Figure 3g In this case, a transfer punch corresponding to the contour shape of the security element 4 must be used to transfer to the valuable item, and when transferring the security element, the transfer punch must be aligned (or overlapped) with the security element 4 on the security element transfer material 1.

[0061] According to a preferred embodiment, the material of the security element layer composite 2 that is not to be transferred is removed, so that the security elements 4 to be transferred are located spaced apart from one another on the temporary carrier 3. Removing the excess security element layer composite material is also referred to as "removing the grid", because the excess security element layer composite material forms a continuous grid with gaps in the shape of the security elements remaining on the temporary carrier, which can be removed from the temporary carrier in a similar manner to a detached winding (Trennwicklung).

[0062] The state after removing the grid is Figure 3h is shown in cross section and in Figure 2 is shown in a top view. Figure 2 It can be seen that the security elements 4 are spaced apart from one another and separated from one another by the region 6 in which no security element composite material is present. In this case, it is not necessary to use a transfer punch in the shape of the security element contour and to align the transfer punch with the security element during the transfer process. Instead, the security element can be transferred, for example, by means of a heated, unstructured transfer roller.

[0063] Figure 3i The result of transferring the security element 4 to the valuable article is schematically shown. The transfer of the security element 4 is achieved by bonding the security element transfer material 1 to the valuable article, in the embodiment shown, the valuable document substrate 30, for example, security paper, pressing the security element transfer material 1 in the region of the security element 4 to be transferred and the valuable article at an elevated temperature, if necessary, and removing the temporary carrier 3 from the transferred security element 4 as a complete carrier layer composite.

[0064] At the location where the cutout 8 enters the first temporary carrier substrate 31, a tear is formed when the temporary carrier 3 is removed from the transferred security element 4, which completely penetrates the first temporary carrier substrate 31, but does not reach the adjacent glue layer 33, let alone the second temporary carrier substrate 32. Therefore, the temporary carrier 3 can be removed as a complete carrier layer composite.

[0065] After transfer to the value document, the security element 4 is present in the reverse layer sequence as on the security element transfer material 1, i.e. the layer of lacquer with a high refractive index is the layer facing the observer. The focusing element 12 formed by the interface 26 between the layer of lacquer with a high refractive index and the layer of lacquer with a low refractive index is well protected within the micro-optical component 11 against wear, dirt and profiling attempts for the purpose of counterfeiting.

[0066] Of course, the security element layer complex 2 of the above-mentioned embodiment and other embodiments or variants of the embodiment of the present invention may also include other layers. These other layers are, for example, feature layers. Feature layers (or functional layers) are layers with features that can be visually identified and / or machine verified. Such layers are known to those skilled in the art. Materials, layer sequences, and application types are not subject to any restrictions. Instead, all materials, layer sequences, and application methods are applicable as long as they do not affect the micro-optical authenticity features of the security element. In this regard, feature layers with strong colored pigments such as magnetic pigments that affect the visibility of the micro-optical authenticity features are inappropriate unless (perceptible) overlap with the micro-optical authenticity features can be avoided.

[0067] The auxiliary layers include, in particular, primer layers for improving the adhesion between adjacent layers and release layers for reducing the adhesion between adjacent layers. It is important in the present invention that certain layers of the security element transfer material have a non-releasable (or non-peelable) connection between them, while other layers of the security element transfer material have a releasable connection between them. Which layers must be non-releasably connected to one another and which layers must be releasably connected to one another can be directly determined by observing the transfer process of the security element to the value document.

[0068] The layers constituting the security element layer composite must be non-detachably connected to one another, since loosening of the connection between two adjacent layers during the production of the security element transfer material, during the transfer process to the value document, or during the subsequent use of the value document renders the security element unusable. From the embodiment shown in FIG3 , it can be seen that the non-detachable connection at the interface 26 between the lacquer layer with a high refractive index and the lacquer layer with a low refractive index is particularly important, since loosening of the connection between the two lacquer layers could affect the function of the first micro-optical arrangement.

[0069] "Non-releasable" means here that the connection between the layers cannot be loosened during the processing or handling of the security element transfer material, when transferring the security element to a valuable item, and when using the valuable item.

[0070] Likewise, during the transfer of the security element to the valuable article, the carrier layer composite of the temporary carrier must not be allowed to loosen from each other. Observing the embodiment shown in FIG. 3 , it can be seen that the adhesive layer 33 must non-releasably connect the first temporary carrier substrate 31 to the second temporary carrier substrate 32. “Non-releasably” here means that at least during the transfer of the security element, or during any processing or handling of the security element transfer material, the bonding cannot be loosened.

[0071] If necessary, an adhesion promoter or primer can be applied, or an adhesion-improving pretreatment can be carried out, in order to improve the adhesion between the layers that have to be non-detachably connected to one another.

[0072] The security element layer composite must be able to be easily loosened from the temporary carrier as a whole. Observing the embodiment shown in FIG. 3 , it can be seen that the lacquer layer 20 or the lacquer layer 22 must be releasably connected to the temporary carrier substrate 31. "Releasable" refers to the fact that the connection can be smoothly loosened during the transfer process of transferring the security element to the valuable article. Since the transfer is usually achieved by heat sealing (or thermocompression bonding), it is necessary to be able to loosen the connection between the security element and the temporary carrier under heat sealing conditions.

[0073] In order to improve the releasability, the temporary carrier substrate 31 may be pre-treated to reduce adhesion, or a release layer may be provided between the temporary carrier substrate 31 and the lacquer layer 20 or the lacquer layer 22 , if necessary.

[0074] The peeling layer may also cause problems for the following reasons, for example, if the peeling layer is not separated as required when transferring the security element, or if the first micro-optical arrangement structure of the security element should still be further processed, for example partially printed, after being transferred to the valuable object. Overprinting of layers with residual peeling layer often leads to unclean printed images. Therefore, it is preferred to use temporary carrier films and lacquer layers with low mutual adhesion to ensure good releasability of the security element from the temporary carrier, or (observing the embodiment shown in Figure 3) the temporary carrier substrate is pretreated to reduce adhesion before connecting the temporary carrier substrate 31 to the lacquer layer 20 or the lacquer layer 22.

[0075] In the first embodiment of the present invention, it is crucial to select suitable materials for the embossing lacquer layer and the adhesive lacquer layer or adhesive glue layer. As described above, an embossing lacquer with a high refractive index ("high-refractive embossing lacquer") is combined with an adhesive lacquer or adhesive glue with a low refractive index ("low-refractive adhesive lacquer"), or an embossing lacquer with a low refractive index ("low-refractive embossing lacquer") is combined with an adhesive lacquer or adhesive glue with a high refractive index ("high-refractive adhesive lacquer"). The interface between the lacquers forms a first micro-optical arrangement structure. A high-refractive-index lacquer in the sense of the present invention is a lacquer with a refractive index of n>1.55, preferably n>1.6, and particularly preferably n>1.7. A low-refractive-index lacquer in the sense of the present invention refers to a lacquer with a refractive index of n<1.45, preferably n<1.3. The refractive index is measured at 589 nanometers and 20°C. It is preferred to use a combination of lacquers with a refractive index difference of at least 0.2, preferably at least 0.3.

[0076] For example, patent document WO 2008 / 098753 A1 discloses a lacquer with a high refractive index, to which reference is expressly made in this connection. The embossing lacquer with a high refractive index mentioned in this patent document is suitable as a high refractive index embossing lacquer for the purposes of the present invention. This particularly relates to free radical-cured and cation-cured UV embossing lacquers. The refractive index of these embossing lacquers can be further increased by adding inorganic particles, preferably in the form of nanoparticles. Patent document WO 2008 / 098753 A1 discloses a variety of materials suitable for increasing the refractive index. Particularly preferred are TiO2, ZrO2, Fe2O3, Fe3O4, Cr2O3, ZnO, Al2O3 and ZnS. The particles can be polymerized into the embossing lacquer, for example. The high refractive index lacquer disclosed in patent document WO 2008 / 098753 A1 has the particular advantage that, compared with many other embossing lacquers, the addition of nanoparticles that increase the refractive index does not result in strong light scattering.

[0077] As very suitable high-refractive-index embossing lacquers there may be mentioned the UV embossing lacquers MO-33 (n=1.602) and MO-SO-01 from C-Coatings BV.

[0078] These embossing lacquers with high refractive index are combined with adhesive lacquers with low refractive index. Common adhesive lacquers for adhesive films are suitable as adhesive lacquers with low refractive index. For example, Norland's UV curing adhesives NOA1315, NOA132, NOA1327, NOA1328, NOA133, NOA1348, NOA136, NOA13685, NOA1369, NOA1375, NOA13775, NOA138, NOA13825 and NOA139 with refractive index between 1.315 and 1.39 can be cited. Adhesive lacquer LOCA-133 with n=1.33 is also well suited.

[0079] The embossing lacquer common in the field of anti-counterfeiting elements can be used as the embossing lacquer of low refraction. The embossing lacquer of low refraction that is very suitable for the purpose of the present invention can be purchased from Shin-AT&C company (Korea). The embossing lacquer of low refraction can advantageously be combined with the high-refractive adhesive lacquer of the refractive index between 1.60 and 1.70 of Norland company, for example the adhesive glue NOA160, NOA161H, NOA1622H, NOA1639H, NOA165H, NOA1665 and NOA170 of UV curing. In addition, adhesive glue NOA161H, NOA1622H, NOA1639H and NOA165H are also heat-cured.

[0080] In the second embodiment of the invention, no embossing lacquers and adhesive lacquers having a special refractive index are required.

[0081] The adhesive lacquer must have a sufficiently low viscosity that it completely adapts (invertedly) to the imprinted focusing structure, ie forms a completely complementary structure at the interface with the structure. For solvent-based adhesive lacquers, the viscosity can be controlled, for example, by adding solvents.

[0082] In order to give the focusing element a suitable shape, the embossing lacquer layer must be relatively thick. Typical layer thicknesses are in the range of 5 to 50 μm. In particular, for the embossing lacquer layer close to the upper end of the region, it is preferred to apply the embossing lacquer layer in a plurality of steps. If the embossing lacquer layer is applied in a plurality of steps, it is preferably carried out according to the method described in patent document EP 1 879 154 A2. In this method, the embossing lacquer layer is applied wet-on-wet in a plurality of steps, i.e. first a first embossing lacquer layer is applied to a temporary carrier, the first layer is partially cured, but not completely, if necessary, then a second embossing lacquer layer is applied, and further embossing lacquer layers are applied if necessary, then the microstructure is embossed in at least the uppermost layer of the coating, and finally the entire lacquer layer is cured.

[0083] The focusing element is preferably a microlens, such as a spherical microlens or a cylindrical lens. However, the type of focusing element is not limited in a certain way, but must be suitable in shape and arrangement for cooperating with the micro-visual object element of the second micro-optical arrangement and producing an optical effect therein.

[0084] Advantageously, in a first embodiment of the invention, the layer composite of the first micro-optical arrangement, the permanent carrier substrate and the first temporary carrier substrate is first produced and only then the first temporary carrier substrate is bonded to the second temporary carrier substrate. During the bonding process, the thinner the layer structure used to produce the first micro-optical arrangement, the higher the quality of the interface between the embossing lacquer layer and the bonding lacquer layer, i.e. the higher the quality of the focusing elements of the first micro-optical arrangement. Furthermore, stresses on the second temporary carrier substrate during the production of the security element transfer material are thereby avoided, which could lead to a weakening of the second temporary carrier substrate.

[0085] A transparent or translucent plastic film, for example a polyester film such as polyethylene terephthalate, polyethylene or polypropylene can be used as the permanent carrier substrate. The thickness of the permanent carrier substrate is preferably selected such that the permanent carrier substrate together with the thickness of the embossing lacquer layer or the thickness of the adhesive lacquer layer (depending on the structure of the security element) produces a suitable focal length for observing the second micro-optical arrangement.

[0086] In the present invention, the second micro-optical arrangement is preferably manufactured as follows, i.e., micro-visual object elements are printed on the surface of the permanent carrier substrate away from the first micro-optical arrangement. However, the micro-visual object elements can also be produced by any other means, such as by embossing. Microcontact printing (µCP) is mentioned as a manufacturing method for high-resolution microstructures. A resolution of less than 1 μm can be achieved by this method. The microstructure is manufactured here with the aid of semiconductor structuring technology and then contoured with an elastomer. A flexible, finely structured punch or printing roller is thus produced, which is suitable for transferring very thin pigment layers when using special printing pigments and surface treating the printed substrate. By applying a suitable pigment with the help of a printing roller manufactured in this way, a second micro-optical arrangement with high-resolution micro-visual object elements can be produced. A primer layer may be required to increase the adhesion of the micro-visual object layer to the layer adjacent to it.

[0087] Another essential element of the present invention is the use of a layer composite as a temporary carrier, which allows the contour of the security element to be transferred to be cut into and the security element to be transferred to the value document substrate simply and without causing damage. Patent document WO 2010 / 031543 A1 discloses a solution for designing a temporary carrier as a layer composite, and the present application includes the disclosure of the materials and methods for producing the temporary carrier-layer composite in this patent document.

[0088] Since in the security element transfer material of the present invention, the first micro-optical arrangement structure with the focusing element is directly connected to the temporary carrier, that is, it is loosened from the temporary carrier during the transfer process, and therefore, if the security element layer complex is not completely cut off, the first micro-optical arrangement structure will be damaged. Therefore, it is necessary to cut the security element transfer material at the following depth so that the security element layer complex is completely cut off. It is unavoidable that the temporary carrier is cut open, and it may be cut open to a considerable depth. Therefore, it is preferred that in the present invention, the contour shape of the security element is cut in by means of a laser, and a laser protection layer is provided between the first temporary carrier substrate and the glue layer and / or between the second temporary carrier substrate and the glue layer, for example, a laser absorbing material or a laser reflecting material is evaporated on the temporary carrier substrate. Alternatively or additionally, the glue between the temporary carrier substrates can also be provided with a laser absorbing material or a laser reflecting material, thereby protecting the temporary carrier substrate located below.

[0089] The contour shape of the security element does not necessarily have to be cut by means of laser cutting, but can also be realized in another way, for example by punching.

[0090] It is also particularly advantageous to use a "self-healing" glue as glue for attaching the temporary carrier substrate. A self-healing glue is a glue that cures only slowly, so that a glue layer damaged during the curing process is still sufficiently active to restore the damage during the curing process. If a self-healing glue is used and the contour of the security element is cut at a point in time when the glue has not yet completely cured, the cut in the glue layer can be restored. The still plastic glue can even penetrate into the cuts in the temporary carrier substrate and completely or partially fill these cuts, or at least adhere the cuts to such an extent that the stability of the cut temporary carrier substrate is not significantly affected.

[0091] The layer composite of the temporary carrier can also include more than two temporary carrier substrates, wherein each two temporary carrier substrates are respectively bonded by means of an adhesive layer, preferably a self-healing adhesive layer. A larger number of layers also makes it possible to provide more laser protection layers, i.e. the more temporary carrier substrates there are, the greater the resistance of the temporary carrier to cutting damage.

[0092] As the transfer adhesive for bonding the transferred security element to the valuable article to be marked, transfer adhesive known to those skilled in the art, especially heat-sealing adhesive, can be used. Preferably, the following heat-sealing adhesive forms a substantially non-sticky coating at room temperature after physical drying or after the melt is cooled. These adhesives are preferred because the security element transfer material is usually not used immediately after manufacturing, but stored, which requires that the continuous material be wound up. If the adhesive layer is not non-sticky, the wound security element transfer material web will be blocked. If about 100cm 2If the security element transfer material sheets can be separated from each other without damage after being stacked and stored at 40°C for 72 hours with a weight load of 10 kg, then there is no adhesion.

[0093] During the production of the security element transfer material, it is usually necessary to increase the temperature and / or pressure several times, which may activate the already existing heat-sensitive and / or pressure-sensitive adhesive layer. Therefore, it is advantageous to apply a heat-sealing adhesive layer as the last step when constructing the security element transfer material.

[0094] The following reference Figure 4a to Figure 4g A second variant of the first specific embodiment of the invention is described, wherein in particular the differences from the first variant are explained.

[0095] First, if Figure 4a As shown, a layer of embossing lacquer 21 with a low refractive index is applied to an embossing film 31, and focusing structures 19, such as concave microlenses, are embossed in inverted form in the embossing lacquer layer 21. As in the first variant, the embossing film 31 is part of the temporary carrier 3, which is removed from the security element when the security element is transferred to the valuable object.

[0096] In the embodiment shown in FIG. 4 , the temporary carrier 3 is in the form of a layer composite consisting of a first temporary carrier substrate 31 (embossing film) and a second temporary carrier substrate 32 which are non-releasably bonded to one another by means of a glue layer 33. This is also possible in the first variant, as in the second variant, initially only the first temporary carrier substrate 31 can be used as an embossing film, which is only bonded to the second temporary carrier substrate 32 after the production of the layer composite consisting of the first micro-optical arrangement, the permanent carrier substrate and the first temporary carrier substrate. In both variants of the first embodiment, it is preferred that the second temporary carrier substrate 32 is bonded to the first temporary carrier substrate 31 only at a later stage of the method for producing the security element transfer material.

[0097] After manufacturing the inverted focusing structure 19, as Figure 4b As shown, a permanent carrier substrate 15, for example a film made of PET, is bonded to an embossed lacquer layer 21 by means of an adhesive lacquer 22 having a high refractive index. At the interface with the embossed lacquer layer 21, the adhesive lacquer 22 forms a structure that is completely complementary to the inverted focusing structure 19. The interface between the lacquer layers forms the focusing elements 12 of the first micro-optical arrangement.

[0098] Alternatively, Figure 4cAs shown, a layer of embossing lacquer 20 with a high refractive index can be applied to the embossing film 15, and focusing structures 10, for example convex microlenses, can be embossed in the embossing lacquer layer 20. The embossing film 15 is a permanent carrier substrate for the security element 4 to be transferred, i.e. a film which permanently remains in the security element layer composite as a stabilizing element.

[0099] Afterwards, if Figure 4d As shown, the temporary carrier 3 is glued to the embossing lacquer layer 20 by means of an adhesive lacquer 23 with a low refractive index. The adhesive lacquer 23 is adapted to the embossed structure of the embossing lacquer layer 20 and forms a completely complementary structure at the interface with the embossed structure 10. The interface forms a focusing element of the first micro-optical arrangement.

[0100] like Figure 4b , 4d As shown in FIGS. 4 e and 4 e , in both cases a first micro-optical arrangement 11 with micro-focusing elements 12 is obtained, which is formed by an interface 26 with focusing structures between a lacquer layer with a high refractive index and a lacquer layer with a low refractive index.

[0101] In contrast to the first variant of the first embodiment, in the second variant of the first embodiment the layer composed of a lacquer having a high refractive index adjoins the permanent carrier substrate 15 .

[0102] In order to generate the micro-optical authenticity feature, a second micro-optical arrangement 13 with micro-optical object elements 14 is produced on the surface of the permanent carrier substrate 15 remote from the temporary carrier 3 and the first micro-optical arrangement 11, which together with the micro-focusing elements 12 form, for example, a moiré magnification arrangement, or generate a tilted image or other optical effect. The second micro-optical arrangement 13 is as follows Figure 4e shown.

[0103] Figure 4e The view is similar to the first variant of the first embodiment in Figure 3g The view in corresponds to . Figure 4e In the method stage shown in , a layer of heat-sealing lacquer 18 has already been applied to the second micro-optical arrangement 13 , wherein a primer layer 17 is arranged between the second micro-optical arrangement 13 and the transfer adhesive layer 18 in order to improve adhesion. Figure 4e Also shown are cutouts 8 which symbolically represent the contour shape of the security element 4 after cutting into the security element layer composite 2. The cutouts 8 not only cut through the security element layer composite 2, but also partially cut through the first temporary carrier substrate 31 and possibly reach into the glue layer 33.

[0104] Will Figure 3g and Figure 4eBy comparing the corresponding views with each other, it can be seen that the significant difference between the first variant and the second variant of the first embodiment is that in the second variant, the thickness of the permanent carrier substrate 15 and the thickness of the adjacent paint layer with a high refractive index must be adapted to the geometry of the microfocusing element 12, while in the first variant, the thickness of the permanent carrier substrate 15 and the thickness of the adjacent paint layer with a low refractive index must be adapted to the geometry of the microfocusing element 12.

[0105] Figure 4f and 4g The view of the first variant Figure 3h and 3i The view in corresponds to . Figure 4f A partial area of ​​the transferred material of the security element after "grid removal" is shown in cross section, Figure 4g The result of transferring the security element 4 according to the second variant of the first embodiment to a value-document substrate 30 , for example a banknote substrate, is shown.

[0106] In the second variant, the focusing element 12 formed by the interface 26 between the layer of lacquer with a high refractive index and the layer of lacquer with a low refractive index is also well protected against wear, dirt and profiling attempts within the micro-optical component 11. However, in contrast to the first variant, the layer of the security element 4 facing the observer is a lacquer layer with a low refractive index.

[0107] The present invention Figures 5a to 5h The second embodiment shown in FIG. 1 differs from the two variants of the first embodiment in that lacquers with different refractive indices do not need to be used, since only one of the lacquer layers remains on the permanent carrier substrate, while the other lacquer layer forms part of the temporary carrier and is removed from the security element 4 during the transfer process to the valuable article. Therefore, the layer consisting of embossing lacquer and the layer consisting of bonding lacquer cannot be non-detachably connected to each other, but must be easily separable from each other when the security element is transferred to the valuable article, thereby producing exposed focusing elements in the security element.

[0108] like Figure 5aAs shown, in order to manufacture the security element transfer material 1 according to the second embodiment of the present invention, a layer 24 composed of embossing lacquer is first applied to the surface of the embossing film 32, and an inverted focusing structure 19, such as a concave microlens, is embossed in the embossing lacquer layer 24. There are no special requirements for the embossing lacquer 24, and any embossing lacquer commonly used in the field of security elements can be used. The embossing film 32 constitutes a part of the temporary carrier 3, which is removed from the security element when the security element is transferred to the valuable article, that is, it is only used as a temporary carrier substrate of the security element. Since the temporary carrier 3 should be removed from the security element to be transferred as a complete layer composite, the embossing lacquer layer 24 must be connected to the embossing film 32 in an inseparable manner. In the case of insufficient adhesion between the embossing lacquer layer 24 and the embossing film 32, a primer layer is applied to the relevant surface of the embossing film 32 before applying the embossing lacquer layer 24, or the surface of the embossing film 32 is pre-treated to enhance adhesion.

[0109] Instead of a single film 32, a layer composite consisting of two or more temporary carrier substrates can also be used, which are non-detachably connected to each other by means of an adhesive layer or multiple adhesive layers, for example using the temporary carriers of the two variants of the first embodiment of the present invention. However, this is not necessary in the second embodiment.

[0110] Afterwards Figure 5b As shown, a film 15, for example made of PET, is adhered to the embossing lacquer layer 24 by means of an adhesive lacquer 25. The adhesive lacquer must have a sufficiently low viscosity so that it completely adapts to the inverted focusing structure 19, i.e. forms a completely complementary structure at the interface with the inverted focusing structure 19. The complementary focusing structure of the adhesive lacquer layer 25 forms the focusing element of the first micro-optical arrangement in the subsequent security element, and the film 15 is the permanent carrier substrate of the security element.

[0111] When the security element is subsequently transferred to the valuable article, the separation between the security element and the temporary carrier occurs at the boundary between the lacquer layers 24, 25 ( Figure 5h ). Therefore, the adhesive lacquer layer 25 must be releasably connected to the embossing lacquer layer 24. In order to ensure that the layers 24 and 25 are separated smoothly when the security element is transferred, it may be necessary to pre-treat the embossed surface of the lacquer layer 24 to reduce adhesion before the permanent carrier substrate 15 is attached, or to apply a special release layer to the embossed surface of the lacquer layer 24. This layer can be a printed layer or a layer applied by means of PVD.

[0112] There are no particular restrictions on the refractive index of the adhesive lacquer 25 (it only has to be greater than the refractive index of the surrounding air). Instead, conventional adhesive lacquers common in the field of security elements can be used. However, it should be noted that the thickness of the permanent carrier substrate 15 and the thickness of the adhesive lacquer layer 25 must be adapted to the geometry of the microfocusing element formed by the adhesive lacquer layer 25 and the refractive index of the adhesive lacquer layer 25, so that a suitable focal length of the microfocusing element is achieved.

[0113] Alternatively, Figure 5c As shown, a layer consisting of an embossing lacquer 24 can be applied to the embossing film 15, and a focusing structure 10, such as a convex microlens, can be embossed in the embossed lacquer layer 24. The focusing structure 10 of the embossed lacquer layer 24 forms a focusing element 12 in the subsequent security element. With regard to the refractive index of the embossed lacquer layer 24, there are no special restrictions, except for the above-mentioned difference in the refractive index relative to the surrounding medium, and lacquers commonly used in the field of security elements can be used. However, the thickness of the carrier substrate 15 and the thickness of the lacquer layer 24 must be adapted to the refractive index of the lacquer and the geometry of the focusing element consisting of the focusing structure 10 in order to achieve a suitable focal length for observing the optical effect.

[0114] like Figure 5d As shown, the film 32 is then adhered to the embossed surface of the embossing lacquer layer 24 with the aid of an adhesive lacquer 25. In this case, the properties of the adhesive lacquer 25 do not play an important role. It is only necessary to ensure that the adhesive lacquer layer 25 is non-releasably connected to the carrier film 32, but releasably connected to the embossing lacquer layer 24, because the adhesive lacquer layer 25 and the carrier film 32 together form a temporary carrier 3 of the transfer material of the security element to be manufactured, which is removed from the embossing lacquer layer 24 when the security element is subsequently transferred to the valuable object, and the embossing lacquer layer 24 forms the first micro-optical arrangement structure of the security element to be transferred. In order to improve the adhesion of the adhesive lacquer layer to the carrier film 32, it may be necessary to provide a primer layer or to pre-treat the carrier film 32 to improve adhesion. It may also be necessary to pre-treat the embossing lacquer layer to reduce adhesion before applying the adhesive lacquer layer or to apply a special release layer on the surface of the embossing lacquer layer to reduce adhesion between the embossing lacquer layer and the adhesive lacquer layer.

[0115] Figure 5e The method stages when manufacturing the anti-counterfeiting element transfer material 1 according to the second embodiment of the present invention are shown. Figure 3fThe method stages shown correspond to those in the production of the security element transfer material 1 according to the first embodiment of the invention, variant 1. The security element transfer material has a temporary carrier 3, which is composed of a first temporary carrier substrate 34 (embossing lacquer layer 24 or adhesive lacquer layer 25) and a second temporary carrier substrate, i.e., a carrier film 32, wherein the first temporary carrier substrate 34 and the second temporary carrier substrate 32 are non-detachably connected to each other. In addition, the security element transfer material also has a first micro-optical arrangement structure 11 with focusing elements 12, which is composed of an adhesive lacquer layer 25 ( Figure 5b ) or embossed lacquer layer 24 ( Figure 5d To produce the second micro-optical arrangement 13, micro-optical object elements 14 are applied, for example printed, on the surface of the permanent carrier substrate 15 remote from the first micro-optical arrangement 11, so that optical effects can be observed through cooperation with the focusing elements 12.

[0116] like Figure 5f As shown, in order to bond the security element to be transferred to the valuable item to be marked, a transfer adhesive layer 18 is applied as the last layer. In order to improve the adhesion at the second micro-optical arrangement structure 13, a primer layer 17 is provided in the embodiment shown. The first micro-optical arrangement structure 11, the permanent carrier substrate 15, the second micro-optical arrangement structure 13, the primer layer 17 and the transfer adhesive layer 18 constitute the security element layer composite 2, and the first temporary carrier substrate 34 and the second temporary carrier substrate 32 constitute the carrier layer composite of the temporary carrier 3.

[0117] Figure 5f (and Figure 3g and Figure 4e The view of FIG. 2 similarly shows the contour shape 7 of the subsequent security element 4 when it is cut into the security element layer composite 2 (see FIG. 2 ). Figure 2 ) After that, the security element transfers a partial area of ​​the material 1. The incision 8 is guided in such a way that the security element layer composite 2 is reliably cut, that is, the incision 8 also reaches the first temporary carrier substrate 34. However, since the second temporary carrier substrate 32 is not cut, the temporary carrier 3 can be removed from the security element as a complete carrier layer composite when the security element is transferred to the valuable article.

[0118] In order to reliably ensure that the second temporary carrier substrate is not cut, similar measures can be taken as for the temporary carrier 3 of the first embodiment. For example, a laser protection layer can be provided between the first temporary carrier substrate 34 and the second temporary carrier substrate 32, and / or a laser-absorbing or laser-reflecting material can be provided on the paint layer constituting the first temporary carrier substrate 34, and then cut by laser. In addition, the temporary carrier 3 described in connection with the first embodiment of the present invention can be used instead of the second temporary carrier substrate 32. Such a temporary layer composite has multiple layers and therefore provides a high degree of reliability in preventing the temporary carrier from tearing during the transfer process, even by means of a method with lower precision than laser, such as by punching into the contour shape of the security element.

[0119] Figure 5g and Figure 3h and Figure 4f The view of shows the state after "grid removal" in a similar manner. It can be seen that the separation between the security element layer composite 2 and the temporary carrier 3 occurs between the embossing lacquer layer and the adhesive lacquer layer, so that these lacquer layers must be releasably connected to one another, while the individual layers of the security element layer composite 2 and the individual layers of the temporary carrier must each be non-releasably connected to one another.

[0120] and Figure 3i and Figure 4g Similarly, Figure 5h The result of transferring the security element 4 to the valuable article is shown. It can be seen that when the temporary carrier 3 is removed from the security element 4, although the lacquer layer 34 is damaged, the second temporary carrier substrate 32 is not damaged, so that the temporary carrier 3 can be removed as a complete layer composite.

[0121] The security element 4 transferred to the value-document substrate 30 has a first micro-optical arrangement 11 with focusing elements 12, which are formed of an adhesive lacquer 25 ( Figure 5b ) or embossing lacquer 24( Figure 5c )constitute.

[0122] The second embodiment has the advantage that no special lacquers need to be used and can therefore be processed very cost-effectively.

[0123] According to a third embodiment of the invention, the security element of the security element transfer material contains only the first micro-optic arrangement of the micro-optic authenticity feature, while the second micro-optic arrangement is formed on the valuable article to be marked itself.

[0124] Figure 6a , 6b , 6c and Figure 7 A third embodiment is shown. Figures 6a to 6c and Figure 7A security element layer composite 2' or a security element 4' is shown, wherein the first micro-optical arrangement 11 is designed as in two variants of the first exemplary embodiment, i.e., consists of a layer of a high-refractive index lacquer and a layer of a low-refractive index lacquer, wherein the focusing element 12 is formed by the interface between the high-refractive index lacquer and the low-refractive index lacquer. However, it is also possible to use Figure 5a to Figure 5h The first micro-optical arrangement 11 according to the second embodiment is described instead of the first micro-optical arrangement 11 according to the first embodiment shown.

[0125] Figure 6a A partial area of ​​a security element transfer material 1' is shown, wherein the security element transfer material 1' is constructed similar to Figure 3e The only difference between the construction shown in FIG. 1 and FIG. 2 is that a transfer adhesive layer 18 is applied to the permanent carrier substrate 15. Figure 3g The security element layer composite 2 shown is different. Figure 6a The security-element layer composite 2 ′ shown contains no second micro-optical arrangement, ie no micro-optical object elements. Figure 3g The primer layer 17 shown is also omitted, but can optionally be provided.

[0126] Figure 6b and Figure 3h , 4f The security element transfer material 1' is shown similarly to the view in 5g after the excess security element layer composite material has been removed in a "grid removal" manner. The security element 4' present as a separate element on the temporary carrier 3 has only the first micro-optical arrangement structure 11, but not the second micro-optical arrangement structure. Therefore, the security element 4' cannot produce an optical effect through the cooperation of the first micro-optical arrangement structure and the second micro-optical arrangement structure.

[0127] In a third embodiment of the invention, a second micro-optical arrangement is provided on the valuable item to be marked. The security element and the second micro-optical arrangement must be arranged relative to each other on the valuable item in such a way that the first micro-optical arrangement of the security element and the second micro-optical arrangement located on the valuable item can cooperate to produce an optical effect. Figure 1 , Figure 6c and Figure 7 A possible arrangement is shown.

[0128] exist Figure 6c In the embodiment shown, the security element 4' and the second micro-optical arrangement 13' with the micro-visual object elements 14' are arranged on opposite surfaces of a transparent value-document substrate, for example a transparent value-document substrate of a film banknote. The same arrangement can also be used if the value-document substrate 30 is an opaque substrate, but has a continuous opening that is closed by the security element 4'.

[0129] exist Figure 1 The security element 4 which closes the continuous opening 9 of the value document is shown on the right side of the value document 5 shown in the top view of FIG. The security element 4 is a security element according to the first or second embodiment of the invention, i.e., comprises Figure 1 The second micro-optical arrangement is shown or indicated as micro-optical object element 14. Figure 6c and Figure 7 As shown on the right, when the security element 4' and the second micro-optical arrangement 13' are arranged on a transparent value-document substrate, the same appearance of the micro-optical authenticity feature is produced for the observer. However, due to the significantly greater distance between the first micro-optical arrangement 11 and the second micro-optical arrangement 13', a different geometry of the focusing element 12 is usually required.

[0130] Figure 7 and Figure 1 An alternative arrangement of a security element 4 ′ and a second micro-optical arrangement 13 ′ according to a third specific embodiment of the invention is also shown or indicated. Figure 1 A value document, for example a banknote, is shown in a top view, wherein the line BB′ indicates the position at which the banknote is to be folded.

[0131] Figure 7 Shown along Figure 1 The cross section of the banknote is obtained by cutting the part of the banknote through the line C-C' in the figure. The bending line B-B' is Figure 7 can be identified as a point. Figure 7 As shown, if the security element 4' without the second micro-optical arrangement structure and Figure 7 The second micro-optical arrangement structure shown or indicated as micro-visual object element 14'' is mounted on a transparent valuable document substrate 30 or a valuable document substrate 30 having a continuous opening in the area of ​​the security element 4', and the first micro-optical arrangement structure of the security element 4' can be aligned with the second micro-optical arrangement structure 13' by folding the valuable document along the line BB', thereby producing an optical effect. In this regard, the third embodiment of the present invention provides the possibility of self-authentication of valuable documents.

[0132] By means of the manufacturing method according to the invention of the security element transfer material, it is possible to manufacture high-quality film security elements having micro-optical authenticity features while minimizing the use of expensive lacquer materials, and to smoothly transfer the film security elements to valuable items without the risk of damaging sensitive micro-optical structures.
