- Security element for an object to be protected and an object to be protected with such a security element
- the invention relates to a security element for an object to be protected, such as security papers, documents of value or the like, as well as an object to be protected with such a security element.
- Items to be protected are often provided with a security element which allows verification of the authenticity of the item and / or as protection against unauthorized reproduction.
- Items to be protected include, for example, security papers, identity and value documents (such as banknotes, chip cards, passports, identification cards, identity cards, stocks, bonds, certificates, vouchers, checks, tickets, credit cards, health cards, etc.) as well as product security elements, such as Example labels, seals and packaging.
- identity and value documents such as banknotes, chip cards, passports, identification cards, identity cards, stocks, bonds, certificates, vouchers, checks, tickets, credit cards, health cards, etc.
- product security elements such as Example labels, seals and packaging.
- the security element is formed as a security thread for a banknote and has, for example, a plurality of microlenses for magnifying a security feature
- the surface of the thread on the lens side can not be provided with adhesive, which causes the thread to sag the embedding in the paper of the banknote spanning paper webs are not connected to the thread and therefore an unwanted lifting (or looper) of these webs can occur from the security thread.
- the result is a reduction in the circulation stability of the banknote. Proceeding from this, it is an object of the invention to provide a security element for an object to be protected with which the initially mentioned difficulties can be solved. Furthermore, an object to be protected should be provided with such a security element.
- the object is achieved by a security element for an object to be protected with an upper side and a lower side, one or more imaging optical assemblies, each of which an associated object only enlarged in front of the top, wherein the one optics assembly or at least one of the optical assemblies a plurality of reflective Mikroab Strukturselemen- te arranged in a first pattern and the associated object is designed as a microstructure object having a plurality of microns structures arranged in a so adapted to the first pattern Mikr o pattern structure, that by means of the reflective microimage elements, the microstructure object is shown enlarged before the top, and wherein the security element has both on the top and on the bottom an adhesive layer with which the security element can be embedded in the object to be protected so that both the upper Ite as well as the bottom is glued to the object to be protected.
- the backs of these reflective microimage elements as well as the spaced apart microns structures or the layer carrying them can be provided with the adhesive layers such that the security element is glued with its two sides, for example, into a banknote can. This eliminates the unwanted lifting of the bars between the windows. star, which are provided in the banknote to allow the magnifying image avoided.
- microimage elements are designed as micro-hollow mirrors, which have a reduced focal length in comparison to refractive microlenses, so that the thickness of the security element (for example, the thread thickness) can be significantly reduced. Thicknesses of less than 30 ⁇ m can be achieved.
- the microimage elements may be arranged on one side of a film and the microstructures on the other side of the film.
- the film may in particular be formed as a transparent film, for example as a PET film. This makes possible a simple way of producing the security element while at the same time providing excellent adjustment of the reflective microimage elements to the microstructures.
- the microimage elements lie in a first plane and the microstructures in a second plane parallel to the first plane.
- the distance between the two planes can correspond to the focal length of the microimaging elements.
- At least one of the adhesive layers or the adhesive layers can be formed as a heat sealing lacquer layer.
- Both adhesive layers or, in particular, the adhesive layer on the upper side of the security element are transparent, transparent here preferably meaning a transmission of at least 10% and in particular of at least 50%.
- the adhesive layer under the reflective microimage elements can also be made non-transparent, preferably white, in order to reduce a shine through of the thread through the back of the banknote (back side sheet).
- the security element according to the invention is here preferably designed such that all optical arrangements of the security element can always map the object assigned to them only in front of the top.
- microstructuring methods can be used, for example embossing methods.
- suitable structures in resist materials can be exposed, possibly refined, shaped and used for the production of embossing tools, using methods known from semiconductor production (photolithography, electron beam lithography, laser lithography,).
- semiconductor production photolithography, electron beam lithography, laser lithography,
- embossing tools are particularly suitable for the production of large areas.
- the security element can in particular be designed as a security thread, tear thread, security tape, security strip, patch or as a label for embedding in the object to be protected.
- the dimensions of the microimage elements are preferably selected to be below the resolution of the human eye. In particular, the dimensions in a range of 3 microns to
- the first pattern and the microstructure pattern may be formed as a hexagonal grid or as a polygonal grid, such as a rectangular or parallelogram grid. It is also an object to be protected with a front side, in which at least one window is formed, wherein in the object to be protected a security element according to the invention is embedded so that it is arranged at least in the region of the window and facing the window with its top , wherein both the top and the bottom of the security element are bonded by means of the adhesive layers with the object.
- the security element in the article to be protected By bonding the security element in the article to be protected on both sides, a high durability can be ensured. For example, if the object to be protected is designed as a banknote and the security element as an embedded security thread, unwanted lifting of the webs between the windows can be avoided.
- the one optical arrangement In the region of the window, the one optical arrangement, one of the Optikan- orders or even several of the optical arrangements of the security element can be.
- the window may be closed with a transparent cover. This leads to a further increase in the durability of the object to be protected.
- the object to be protected is preferably substantially flat.
- the object to be protected can be designed as security paper, value document or the like.
- security paper is understood here in particular as the precursor that can not be processed to form a value document which, in addition to the security element according to the invention, may also have further authenticity features (such as, for example, luminescent substances provided in the volume).
- Value documents are here understood, on the one hand, documents produced from security papers.
- value documents can also be other documents or items which can be provided with the security feature according to the invention, so that the value documents have non-copyable authenticity features, whereby an authenticity check is possible and undesired copies are prevented at the same time.
- the substrate of a security paper or value document is particularly preferably made of paper made of cotton fibers, as used for example for banknotes.
- the substrate may also consist of paper of other natural fibers, also preferably of synthetic fibers, ie a mixture of natural and synthetic fibers or also preferably of at least one plastic film.
- a two-sided coating or lamination of the substrate with in each case at least one plastic film results in a security paper, as described in DE 102 43 653 A9, the disclosure of which is fully incorporated in this regard in this invention.

- FIG. 1 shows a plan view of a banknote 2 with a security element 1 according to the invention
- Fig. 2 is an enlarged view of the section along the line A-A in Fig. 1; 3 shows a further embodiment of the security element 1 according to the invention in a sectional view according to FIG. 2;
- FIG. 4 shows a further embodiment of the security element 1 according to the invention in a sectional view according to FIG. 2;
- FIG. 5 shows a further embodiment of the security element 1 according to the invention in a sectional view according to FIG. 2, and
- FIG. 6 shows a top view of a chip card 37 with a security element 35 according to the invention.
- the security element 1 is designed as a security thread and so integrated into an object to be protected 2 (here banknote 2) that the security thread in the spaced-apart window areas 3 is exposed or is not covered by the banknote, since in the window areas 3 recesses are formed in the top of the bill, so that a clear view is given to the security thread 1.
- banknote 2 an object to be protected 2
- the security element 1 comprises a carrier 4, which has on its first side 5 microstructures 6 and on its opposite second Page 7 has several micro-hollow mirror 8.
- micro-hollow mirrors 8 are arranged in a plane perpendicular to the plane of the drawing in FIG. 2 in a grid with a fixed geometry (here, for example, a hexagonal grid) and thus flat in a first pattern.
- microstructures 6, which form a microstructure object or image M are likewise arranged in a plane perpendicular to the drawing plane of FIG. 2 in a grid with a fixed geometry (here, for example, a hexagonal grid) and thus flat in a microstructure pattern.
- the microstructure pattern is adapted to the first pattern and both patterns are aligned with each other so that when viewing the security element through the window areas 3 (direction of the arrow Pl) the microstructures 6 together with the micro-cavity mirror 8 a modulo magnification arrangement form.
- the basic principle of such a Mo dulo- magnification arrangement is described for example in WO 2009/000528 Al, the entire contents of which is hereby incorporated, wherein the microstructure object M of the present invention, the motif image according to the teaching of
- WO 2009/000528 Al corresponds.
- the microstructure object M for a viewer in the respective window area 3 is enlarged as a security feature (as a target image within the meaning of WO 2009/000528 A1).
- a security feature as a target image within the meaning of WO 2009/000528 A1.
- the carrier 4 comprises a PET film 9 onto which a first layer 10 of radiation-curing lacquer (for example UV lacquer) having the microstructures 6 is applied.
- the microstructures 6 can be produced in a known manner, for example by embossing in the UV varnish 10 and subsequent printing and stripping of paint.
- certain color transfer processes or microtip printing techniques can be used, which are described, for example, in PCT / EP2008 / 010739 or WO 2008/000350 and whose disclosure content is included in the present application in this respect.
- a second layer 11 of radiation-curing lacquer for example, UV lacquer
- the negative mold of the micro-hollow mirror 8 is embossed.
- the side of the second layer facing away from the PET film 9 is coated with a reflective coating 12 (eg, a metallization).
- the micro-hollow mirrors 8 are thus formed as rear surface mirrors.
- a mirror coating 12 in the form of a metallization has the advantage that it is electrically conductive and magnetizable.
- a color with magnetic pigments can also be concealed which has a magnetization that is the same throughout or different in different subregions.
- the security element according to the invention thus has the additional security features of electrical conductivity and magnetic coding.
- the inside of the reflective coating 12 of each micro-hollow mirror 8 or the embossed shape for the micro-hollow mirror 8 here has the shape of a spherical cap with a radius of curvature of 38 microns and a height hl of about 3.1 microns.
- the maximum thickness of the second layer 11 here amounts to approximately 5.1 .mu.m, the PET film has a thickness of 12 .mu.m and the height h.sub.2 of the first layer is 10 2 ⁇ m.
- the micro-hollow mirrors 8 Since the radius of curvature of the micro-hollow mirror 8 is 38 ⁇ m, the micro-hollow mirrors 8 have a focal length of 19 ⁇ m. Due to the described structure, the microstructures 6 are spaced approximately 19 ⁇ m from the hollow micromirrors 8 and thus lie in the same plane as the focal points of the micromirrors 8, so that the desired magnification imaging of the microstructures 6 of the security feature is effected , The side facing away from the micro-hollow mirrors 8 side of the first layer 10 is the top 13 of the security element 1, on which a first adhesive layer 14 is applied from heat sealing lacquer. Furthermore, the rear side of the micro-hollow mirrors 8 and thus the reflective coating 12 form the underside 15 of the security element 1.
- a second adhesive layer 16 (here again a heat sealing lacquer layer) is applied. Due to the use of hollow micro mirrors 8, it is thus possible in the case of the security element 1 according to the invention to form an adhesive layer 14, 16 both on the upper side 13 and on the lower side 15.
- the second adhesive layer 16 serves to bond the security element 1 to a back side sheet 17 of the banknote 2, as shown in FIG. 2.
- the first adhesive layer 14 serves to connect the security element 1 to a front side sheet 18 of the banknote 2, in which case in particular the webs 19 of the front side sheet 18 are glued to the security element 1 between the window regions 3, so that an undesired lifting of these webs 19 can be prevented by the security element 1.
- the security element 1 is inserted into the banknote 2 and an enlarged image of the security feature now takes place in front of the top side 13 or in front of the front side leaf 18.
- the width of the security thread 1 (extension from left to right in Fig. 1) is equal to the width of the window areas 3.
- the width of the security thread 1 is chosen larger, so that by means of the first adhesive layer 14 also side of the window areas 3 gluing with the front side sheet 18 is possible.
- the micro-hollow mirrors 8 with the associated microstructures 6, which lie in front of one of the window regions 3, can be referred to as an optical arrangement which image the microstructure object M (the object associated with the micro-hollow mirrors 8) in front of the upper side 13. It is therefore possible to designate the micro-hollow mirrors 8 and the micro-structures 6 in front of each window area 3 as a separate optical arrangement, so that the security thread 1 has a plurality of optical arrangements. Of course, one can also view all micro-cavities 8 and all micro-structures 6 as belonging to a single optical arrangement. But it is also possible to provide per window area 3 multiple optics arrangements. It is essential here that all optical arrangements always represent the respective object only in front of the upper side 13.
- the microstructures 6 on the one hand and the micro-hollow mirrors 8 on the other hand are embossed on two separate foils (for example PET foils) and given a metallization or color. These two films are then joined together to form a structure according to FIG. 2, so that instead of the PET film 9 shown in FIG. 2, two laminated PET films are present. Should the distance between the hollow micromirrors 8 and the microstructures 6 be changed by this structure, the curvature of the microcavity mirror 8 would have to be adjusted so that the microstructures 6 in the assembled state are again located in the focal points of the micromirrors 8. Of course, the distance depends essentially on the thickness of the two PET films and the amount of adhesive necessary for laminating.
- FIG. 3 shows an embodiment of the security element 1 according to the invention in the state embedded in the banknote 2, which can be referred to as a laminating variant.
- the microstructures 6 and micro hollow mirror 8 are first manufactured separately.
- the microstructures 6 are formed on a UV lacquer layer 20, which is applied to a first carrier foil 21.
- the micro-hollow mirrors 8 are formed in a UV lacquer layer 22 (by embossing and metallizing), which is applied to a second carrier foil 23.
- the two carrier films 21 and 23 are preferably PET films.
- the microstructures 6 and micro-hollow mirrors 8 thus formed are laminated together, the micro-hollow mirrors 8 and the micro-structures 6 facing one another, as can be seen in FIG. 3. Between them is only the laminating adhesive 24. However, it is also possible, one or more additional paint layers
- a first adhesive layer 14 and on the underside 15 of the security element 1 are again a first adhesive layer 14 and on the underside 15 of the security element 1, a second adhesive layer 16 is formed with which the security element 1 with the front and back side sheet 18, 17 of the banknote 2 is glued.
- the carrier films 21 and 23 protect the internal microstructures 6 as well as the inside micro-hollow mirrors 8 excellently against environmental influences and attacks by potential counterfeiters.
- a structure is shown in which it is not necessary to place a film between the microstructures 6 and the micro-cavity mirror 8 as a spacer.
- FIG. 4 shows a further embodiment of the security element 1 according to the invention in the state embedded in the banknote, which can be produced as follows.
- a first UV lacquer layer 25 which is applied to a PET film 26
- microstructures 6 are embossed and colored using a suitable method.
- a second UV lacquer layer 27 is applied to the embossed UV lacquer layer 25 and in a second embossing the molds for the micro-hollow mirror 8 are generated, which are then formed by vapor deposition with a metal layer 12.
- the second adhesive layer 16 is then applied to the hollow micro-mirrors 8 thus formed.
- a protective lacquer layer not shown, can be formed on the hollow micro-mirrors 8, on which the second adhesive layer 16 is then applied.
- the first adhesive layer 14 is in turn applied. With the two adhesive layers 14 and 16, bonding or fastening of the security element 1 in the banknote 2 can be carried out.
- FIG. 5 shows a further embodiment of the security element 1 according to the invention, which is inserted into the banknote 2.
- the microstructures 6 and the micro-hollow mirrors 8 are produced separately.
- the microstructures 6 are embossed in a UV lacquer layer 30, which is formed on a PET film 31, and then dyed.
- the micro-hollow mirrors (or their negative mold) are embossed in a UV lacquer layer 32, which is applied to a PET film 33.
- the embossed shapes for the micro-hollow mirror 8 are mirrored either now or after laminating ver.
- the PET film 33 is then laminated together with the UV lacquer layer 30 (laminating adhesive 34), wherein the application amount of the laminating adhesive 34 is adjusted so that the moire or modulo-magnified images (in this case the microstructure object) can be seen sharply.
- the first and second adhesive layer 14, 16 is formed to bond the security element 1 in the manner described with the front and back side sheet 18, 17 of the banknote 2.
- the PET film 31 may in turn be detachably connected to the UV lacquer layer 30.
- the first adhesive layer 14 is applied directly to the UV lacquer layer 30.
- the security element 1 according to FIG. 5 can also be produced by the following working steps. First, the UV lacquer layer 30 is embossed and colored to produce the microstructures 6. Thereafter, the PET film 33 is laminated to the UV lacquer layer 30. On the laminated PET Film 33, the UV lacquer layer 32 is formed and formed in this UV lacquer layer 32, the micro-hollow mirror 8 by embossing and coating.
- the security element 1 according to the invention can e.g. be formed as a security element 35 with a rectangular shape so that it lies in the window portion 36 of the front side sheet 18 of the banknote 2.
- the security element 35 is preferably larger than the window area 36, as indicated in FIG. 1 by the dashed outline, so that gluing of the security element 35 to the front side panel 18 is possible by means of the first adhesive layer 14.
- the window portion 38 when embedding the security element 36 in a chip card 37 (as an example of a document of value), as shown in Fig. 6, the window portion 38 have a transparent cover 39, with which the security element 35 is bonded by means of the first adhesive layer. For a permanent embedding of the security element 35 is achieved.
- the banknote may be formed, for example, as a film composite banknote, in which both the front and the rear side sheets 17, 18 are multilayered, wherein the outermost layer is transparent and in the underlying layer at the front side sheet 18, the window portions 3 are formed.
- micro-cavity mirrors 8 have been described, respectively. It is understood that the microvoid mirrors are given as representative of reflective micro-imaging elements. In particular, it is possible to use diffractive elements as reflective imaging elements, provided that they realize the desired imaging properties (in the same or similar manner as the micro-hollow mirrors 8).
- the microimage elements can be formed, in particular, by microvoided mirrors having a circular or polygonal limited base surface, or by elongate cylindrical microvoid mirrors whose lengthwise extension is more than 250 ⁇ m, preferably more than 300 ⁇ m, more preferably more than 500 ⁇ m and in particular more than 1 mm. Furthermore, mirrors, Fresnel mirrors, zone mirrors or other elements having a reflective effect are possible as microimage elements.
- the micro-hollow mirrors 8 may have a spherical curvature or an aspheric curvature.
- the mirror coating 12 of the micro-hollow mirrors 8 can be realized, for example, by means of an applied metal layer (vapor-deposited, for example). Typically, an aluminum layer with a thickness of, for example, 50 nm is applied. Of course, other metals such as silver, copper, chromium, iron, etc., or alloys thereof can be used. The combination of several metals on and / or next to each other is also possible, for example, a partial vapor deposition with Cu and then a full-surface vapor deposition with aluminum. Also, as an alternative to the metal, high-index coatings can be applied, for example MgF 2 , ZnS or TiO 2 . When choosing a suitable thickness, the reflective effect can be additionally increased by interference effects.
- the corresponding layer thickness is about 60 nm.
- a thin layer system of, for example, alternately high and low refractive layers can be applied so that the sequence of layers acts as a reflector.
- Such layer systems can be tailored for a particular wavelength.
- the mirror coating 12 may be over the entire surface of the individual micro-hollow mirrors 8. However, it is also possible to carry out a coating which is only regional or grid-shaped, so that the micro-hollow mirrors 8 are semitransparent. Also, the thickness of the coating can be chosen so that instead of a complete mirroring is present semitransparent mirroring.
- Semitransparent mirroring is understood to mean, in particular, such a mirroring in which the transmission averaged over at least one micromirror is in the range from 10% to 90%.
- the mirror coating may also be realized as a color-shifting coating, e.g. has a layer system of absorber, dielectric and reflector.
- the color-shifting side of the layer system may be facing or facing away from the microstructures 6.
- the color generated by the layer system can be adapted to the color of the microstructures 6.
- the security element 1 may also have other security features, such as holograms, clear text or other known security features, for example, on page 18 of the description
