Description

The present document relates to a security element for a data carrier with an individualized transparent register, a production method for such a security element and a use of the manufacturing method.

Data carriers, such as security documents or identity documents, in particular banknotes, credit cards or passports, or other forgery-prone value documents such as branded articles are provided with security elements for security, which allow a verification of the authenticity of the object or the data carrier and which also serve as protection against unauthorized production , Such security elements often produce a highly visible visual impression, which allows a review of the security element even without technical aids, such as the naked eye. A security element can be embedded in such data carriers, for example in a banknote or in a chip card, or designed as a self-supporting transfer element, for example as a patch or label, which is applied to a data carrier or other object to be secured after its production. Alternatively, however, the security element can also be integrated into the data carrier during production, for example a security thread in banknotes.

For the purposes of the present invention, data carriers are in particular bank notes, shares, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other papers which are at risk of forgery such as passports or other identification documents and also card-shaped data carriers, in particular credit or chip cards, as well as production assurance elements, such as labels. Seals, packaging and the like. The term "data carrier" also includes precursors, in particular non-executable precursors of such data carriers which, for example in the case of security paper, are present in quasi-endless form and are processed further at a later time. Such data carriers may contain windows or see-through windows which are covered with a foil which optionally forms a carrier for a security element.

In order to prevent forgery or replication of security elements, for example with high-quality color photocopiers, it is known to provide such security elements with transparency registers. Such transparency registers are usually designed as information-related motifs, for example as alphanumeric characters or other symbols which convey to a viewer certain information, possibly also abstract information. Such a motif is subdivided into a plurality of elements which are arranged on the front side and the back side of a suitable carrier substrate, so that these elements, when viewed in transmitted light, provide the desired motif. For this purpose, on the one hand, the motif elements on the front and back of the carrier substrate partially overlapping or register exactly, d. H. with sufficient accuracy of fit, applied on the front and back. This is usually done in the simultaneous printing process, which allows a high registration accuracy of different printed layers on opposite sides of a carrier substrate. In the case of a see-through register, the registration accuracy of the motif elements applied to the front and rear sides of the carrier substrate can form a security feature that is difficult to imitate by a counterfeiter and can easily be checked by a user.

Such transparency registers produced by the simultaneous printing process are based on either a completing or a partially overlapping printing of the elements of the see-through register on the front and back sides of the carrier substrate. In the case of the complete imprint, the elements of the see-through register are arranged in registration, ie in register, on the front and back so that in transmitted light at each point of the see-through register the light passes through only one printing layer, either on the back or on the front side of the carrier substrate. In other words, the elements of the see-through register in the region of the see-through register are completed in such a way that the light, when viewed in transmitted light, passes through the carrier substrate and exactly one printing layer. If the print layers applied to the front and back have the same color strength, the result is a see-through register with a light / dark contrast that is uneven in transmitted light. Therefore, it is preferable to reduce the color strength of the front-side reflection color (observation side) from the back-side reflection color.

In the case of partially overlapping printing of the elements of the see-through register, the elements are arranged, for example, at their edge area not exactly in register butt-to-joint, but have an overlapping area.

For the purposes of the present specification, an opaque layer has little or no light transmission in the entire visible wavelength range. Usually z. B. banknote paper, which is printed on one side over the entire surface, as measured by means of a see-through densitometer on an opacity value of about 50 to 70%. The inks used for transparency tabs increase the opacity to about 80% to 95%. A transparent layer is furthermore preferably clear and allows undisturbed observation of lying in the viewing direction behind the transparent layer objects. A translucent layer, on the other hand, noticeably reduces the intensity of the light passing through it, which is recognizable to a viewer, while at the same time light which is still recognizable passes through. It typically has a light transmission between 20% and 70% throughout the visible spectrum. A translucent layer can in principle be clear or cloudy or milky. It can be colorless or colored.

The carrier substrate has a sufficiently high translucency, which allows a perception of the rear elements of the see-through register when viewed in transmitted light. At the same time, the carrier substrate has a sufficiently low translucency that prevents perception of the rear-side motif elements when viewed in incident light, so that only the elements of the transparent register that are at the front in the viewing direction are perceptible to an observer in reflected light. The see-through register is preferably divided into front and back elements in such a way that, for example, the front-side elements provide the observer with no information or information different from the see-through register.

In this case, however, no individualized or personalized transparency register can be created with the simultaneous printing method, since the elements of the transparency register are fixed by the print template, such as the printing plates. Individualized and personalized imprints, on the other hand, can be easily made using a laser printer or an inkjet printer. However, these printing methods do not allow register-true printing on the front and back of a carrier substrate, since in this printing method, a simultaneous printing of front and back of a carrier substrate is not possible and corresponding tolerances result by transfer processes of the carrier substrate between the various printing steps, the creation of a Transparency register in sufficient quality, that is with sufficient registration accuracy and / or register, prevent.

It is also known to produce transparency registers in the form of recesses in superimposed layers by means of a laser irradiation. For this purpose, suitable lasers such as UV, CO ₂ , Nd: YAG or Nd: YVO ₄ laser are used and correspondingly suitable materials for the elements of the see-through register are used, which ablation, sublimation or a chemical or physical change of the printed elements of the Permit transparency register. By such a laser treatment, an individualized or a personalized transparency register can be created. At the same time, the remaining layers, for example a carrier substrate, are chosen such that no or at least no interaction with the laser radiation that is recognizable to a viewer takes place.

However, the information of the see-through register created by such a laser irradiation is immediately recognizable not only when viewed in transmitted light, but also in front or back viewing in reflected light, which is often undesirable.

This is from the EP 1 054 778 It is known to print an interference structure on the front and / or rear side of a carrier substrate next to such a see-through register created by laser treatment, which has a similar appearance as the see-through register in the case of supervision, with which the information of the see-through register is to be concealed when viewed in reflected light. However, this approach does not provide satisfactory results because, among other things, the success of this approach depends on the concrete see-through register, that is, for example, differs from banknote to banknote.

The present invention is therefore based on the object of specifying a security element for data carriers with an individualized transparent register whose information (see-through information) is not recognizable when looking at the incident light or is present only in fragments and therefore not completely readable. It is a further object of the invention to specify a corresponding production method and a suitable use of the production method.

This object is achieved by a security element, a manufacturing method and a use having the features of the independent claims. The dependent claims relate to preferred embodiments and further developments of the invention.

The security element according to the invention initially comprises a translucent carrier substrate with a front side and a rear side. The carrier substrate is usually flat. Due to the translucency, a layer arranged in the viewing direction on the back side of the carrier substrate is largely or completely obscured when viewed from the front in the incident light. For this purpose, the translucent carrier substrate is preferably opaque in a plan view and possibly cloudy or milky. The carrier substrate can be made of paper, for example cotton paper, a paper-like material, or else of a film, for example a film Plastic film made of PET (polyethylene terephthalate), which is designed to opaque by a suitable coating or suitable additives in incident light.

On the translucent carrier substrate, a front side layer is arranged at least in a given region thereof, which is translucent or opaque, so that the applied front side layer can be seen in transmitted light for a viewer. The front side layer consists of a material which is changeable or ablatable by irradiation, for example by laser irradiation. In the given area, the front side layer is not applied over the entire area, but partially, that is fragmented, such that at least one application area in which the front side layer is applied is provided in the given area on the front side of the carrier substrate, and a recess in which the front side layer is not applied and in which thus the carrier substrate can be viewed directly. Likewise, on the back side of the translucent carrier substrate, a backside layer is applied, which in turn is translucent or opaque, is changeable or ablatable by irradiation, for example by laser irradiation and which in turn is applied fragmented in the given region of the carrier substrate. Preferably, the front side and / or the rear side have a plurality of application areas and a multiplicity of recesses of the front side layer and / or back side layer in the given area. In this case, the at least one recess and the at least one application region of the front and back side layer are arranged in the given region of the carrier substrate such that at least one application region of front side layer or back side layer is arranged at each point of the given region. Thus, in the given range, when viewed in transmitted light, a transmission which is less than the transmission of the translucent carrier substrate results, since the transmitted light in each case passes through an application region of the front side layer and / or backside layer. The application areas of the front side layer and the back side layer can be arranged completely or partially overlapping.

In the given area, there is also a motif generated by irradiation, preferably by laser irradiation. The irradiation, for example the parameters of the laser irradiation, and the carrier substrate are selected in such a way that the carrier substrate does not change optically upon irradiation. The irradiation is further selected such that the desired change or the desired ablation of the front side layer and / or the back side layer results during irradiation. If the application areas of the front side layer and the back side layer overlap at an irradiated point in the given area, then both layers are changed or ablated. The change is chosen such that there is an increased transmission of the irradiated areas of the front side layer and / or the back side layer in the transmitted light.

The motif generated by irradiation is arranged in the given area in such a way that the motif extends over both the at least one application area and the at least one recess of the front side layer and / or back side layer. Since there is at least one application area of front side layer and rear side layer at each point of the given area, at least one of the two layers is changed or ablated at each point of the motif to be applied. At locations of the given area where the application areas of the front and rear side layers overlap, these irradiated areas are changed or ablated accurately.

The security element according to the invention and the production method according to the invention allow to generate with the aid of irradiation an individualized or personalized see-through register in the form of a motif which, in transmitted light due to the change or ablation, has a higher transmission compared to the surrounding area, ie the background of the motif , that is translucency, shows. At the same time is achieved by the inventive arrangement of the subject, which extends over the respective at least one application area and the respective at least one recess of front side and / or back layer, that at Auflichtlichtrachtung both on the back and on the front of the security element by Radiation generated motif is only partially visible. Therefore, the transmitted light recognizable information of the see-through register is not anticipated by a reflected light observation. In other words, the information that gives the complete irradiation-generated motif to a viewer differs from the information perceptible to a viewer when viewed in incident light.

The condition according to the invention, according to which at least one application area of the front-side layer or the back-side layer is arranged at each point of the given area, relates to the design of the security element before the irradiation. Even though the irradiation causes local ablation of the obverse and reverse side layers, these transversal image-forming recesses are clearly distinguishable from recesses resulting from an overlap of recesses in the pre-irradiation applied front side layer and Rear side layer would result, since a radiation can also be detected on the finished product, for example, the contour sharpness of the ablated by irradiation areas, on traces of smoke or on preferably optically imperceptible changes in the carrier substrate.

In a preferred embodiment, in each case at least one application region of the front side layer and the back side layer does not overlap in the given region. In the case of a plurality of application areas of the front-side layer and / or back-side layer within the given area, the plurality of application areas of the front-side layer and the back-side layer do not overlap, so that exactly one application area of either the front-side layer or the back-side layer is disposed at each location of the given area. When viewed in transmitted light, this complementary embodiment of the application areas does not result in a disturbing reduction in the translucency of the security element in overlapping areas of the application areas or the at least one application area of front side layer and rear side layer, which improves the visual impression for the viewer, as for example when viewed in transmitted light - apart from the motif introduced by irradiation - gives a uniform shade of gray.

Different materials are available for the front and back layers. For example, front and back layers may be color layers containing laser absorbing materials, e.g. As carbon black, graphite, aluminum flakes or Milori blue, the z. B. absorb at 1064 nm. Backside and front side layer can also be formed as a metallic layer, for example as an aluminum layer, which can be ablated by laser.

Furthermore, the fragmentation of the front surface layer and the back surface layer according to the present invention can be realized by various application methods. In the simplest case, a color layer in the simultaneous printing method or blanket-to-blanket printing method is applied to the front side and the back side of the carrier substrate, whereby the required fragmentation and in particular a complete printing of the front side and back side layer can be easily realized. Alternatively, a washing ink can be applied by means of the abovementioned printing methods on the front and rear side of the translucent carrier substrate, onto which surface the front side layer and / or rear side layer are then applied over the whole area. Subsequently, the washing color is broken up with washing solution, thereby detaching the overlying front or back side layer, which results in the desired fragmentation of front side and back side layer. Such washing methods are for example in the EP 1 972 462 and the prior art mentioned therein, in particular the EP 1 023 499 described, the corresponding disclosure of which is hereby incorporated into the following specification. The use of this washing method is particularly advantageous for security elements in the form of film strips such as security strips. However, instead of a printing or washing ink, an adhesive layer can also be applied in regions to the translucent carrier substrate using the methods mentioned. In this case, the adhesive layer is applied at the locations which are provided as application areas of front side and / or rear side layer. After the adhesive layer has been applied, the carrier substrate is pressed against a metal layer or an otherwise suitable layer so that the metal or other layer bonds with the applied adhesive layer and remains on the carrier substrate, but can be removed again in the other places. This process corresponds to the so-called cold foil application.

Alternatively, the application areas of the fragmented front side layer and / or rear side layer can first be produced on a film element and then applied to the translucent carrier substrate, for example as a transfer element. In this case, the applied layer may be a paint film. However, it is also possible to apply other layers, for example layers constructed in a complex manner or provided with additional information, such as layers with embossing information in the form of matt / gloss effects, holographic structures, Colorshiftfarben, infrared-absorbing or luminescent colors or other structured, such as screened lacquer or metal films. This process is also referred to as film application, which may be both a hot and a cold foil application. In the case of hot-foil application, the layer to be transferred is applied to the translucent carrier substrate by means of a heat sealing lacquer layer and the carrier foil of the foil element is then removed. In the case of cold foil application, by contrast, as already outlined above, an adhesive layer is firstly generated in regions on the translucent carrier substrate, wherein the adhesive layer comes to lie at locations which correspond to application areas of the fragmented front side layer and / or back side layer. The application of the adhesive layer can be done for example in simultaneous printing or Offsetrollendruckverfahren. The acted upon by the adhesive layer side of the translucent carrier substrate is then pressed over the entire surface against an example metallized film or otherwise suitably coated carrier so that, for example, the metallization after detachment of the metallized film remains on the areas acted upon by the adhesive layer areas.

If the fragmented front-side layer and / or back-side layer is transferred in a film application or transfer process, it is preferable to provide partially overlapping application of the front-side and back-side layer application areas, since the registration accuracy of the generated application areas may be small.

In general, the front and back layers can be constructed differently. However, front side and back side layers are preferably of the same type, for example metal layers or ink layers with an optionally different color impression. Likewise, front and back layers can be applied to the carrier substrate by various methods. However, the front and back layers are preferably applied by the same method, more preferably in one step, such as in the simultaneous printing process.

In a preferred embodiment of the security element according to the invention, not only the motif created by irradiation forms a see-through register, but also the fragmented front side and back side layers form a further see-through register. In the simplest case, the at least one application region of the front side layer then forms an element of the further transparent register. Likewise, the at least one application region of the backside layer also forms an element of the further transparent register. Both layers then complement each other in transmitted light to the other transparent register. In this preferred embodiment, the given area corresponds to the area of the further transparent register.

Alternatively or additionally, the at least one application area of the front-side layer or optionally the plurality of application areas of the front-side layer form a supervisory motif, which is perceptible when the security element is viewed in incident light. In this case, the at least one application region of the backside layer or the plurality of application regions of the backside layer preferably also forms a topographical motif, which is particularly preferably the negative of the topographical motif of the front side layer. Thus, the inventive radiation-generated see-through register is combined with a known static read-through register.

In a preferred embodiment of the security element according to the invention, a motif is repeated with the motif created by irradiation, which motif is already located elsewhere in the security element or the data carrier. For this purpose, for example, on such a disk printed ciphers, such as serial numbers, in question, which individualize a document of value, such as a banknote, a check or a passport. Such a numbering can be completely or partially repeated by the inventive motif generated by irradiation. For example, the inventive radiation-generated motif repeats the last digit, a particular digit string, a check digit, or a letter of the digit. Furthermore, it is possible, for. B. repeat a terminal digit "5" as the written word "five" in the look-through register. Another variant is z. For example, the repetition of an Arabic numeral in the form of a Roman numeral. Likewise, for example, a two-dimensional or a three-dimensional barcode of the value document can be repeated within the subject generated by irradiation. Furthermore, the transparency register according to the invention offers the possibility of repeating an individualizing or personalizing information, for example an image motif. These possibilities can also be combined. This repetition provides an additional opportunity for visual and / or machine verification of the data carrier.

Another advantage of the invention is that so-called "composed counterfeits" are made more difficult. By composed counterfeiting one understands falsifications, which by separation of the substrate layers, d. H. by separating the front side from the rear side, and combining the resulting front side or back side with a counterfeit substrate layer (which is obtainable, for example, by means of Inket printing). In order to provide the security element according to the invention, the counterfeit substrate layer would have to be applied precisely to the original counterpart, which is hardly feasible without offset in practice. In addition, the offset may be detected by a suitable sensor (eg, scanner or camera based) in a bean node processing system.

Further exemplary embodiments and advantages of the invention are explained below by way of example with reference to the accompanying figures. The examples represent preferred embodiments which in no way limit the invention. The figures shown are schematic representations that do not reflect the real proportions, but serve an improved clarity of the various embodiments.

In detail, the figures show:

1 a banknote with a security element;

2a - 2d a first embodiment of the security element;

3a . 3b a second embodiment of the security element;

4a - 4c a third embodiment of the security element; and

5a - 5c Representations of an example of real pattern of the security element according to the invention.

In 1 is a banknote as a data medium 1 with a security element 2 shown. Next to the security element 2 is on the banknote 1 the printed denomination "50".

In the 2a to 2d is a first embodiment of a security element 2 shown, and outlined its manufacture. In 2a is a cross section through the security element 2 presented before the irradiation. The security element 2 comprises a translucent carrier substrate 3 with a fragmented front side layer 4 and a fragmented backside layer 5 , The fragmented front side layer 4 has order areas 4a and recesses 4b on. Similarly, the fragmented backside layer 5 contract areas 5a and recesses 5b on. The order areas 4a . 5a and recesses 4b . 5b the front side layer 4 and the backsheet layer 5 are arranged such that at each point of the translucent carrier substrate 3 exactly one order area 4a . 5a from front side layer 4 or backside layer 5 is arranged. In this respect, the fragmented front side layer 4 and the fragmented backside layer 5 Completely arranged. The order area 4a preferably has a lighter shade than the application area 5a on, so in the transmitted light from the side 4 considered an equal or similar dark stage shows and thereby sets a uniform homogeneous impression. The translucent carrier substrate 3 consists of paper, which has a suitable layer thickness, so that the carrier substrate is opaque when viewed in reflected light. When viewed from the front in reflected light, therefore, only the order areas 4a the front side layer 4 perceived on the carrier substrate, in Auflichtlichtrachtung the back only the order areas 5a the backside layer 5 ,

Subsequently, the security element is irradiated in areas with a Nd: YAG laser with a wavelength of 1064 nm perpendicular to the translucent carrier substrate. The laser irradiation both the front side layer 4 as well as the backside layer 5 changed so that they become transparent. The laser treated areas are in the cross section of 2 B with the reference number 6 characterized.

In 2c a top view of the laser-treated security element is shown. From a viewer can continue the untreated job areas 4a the front side layer 4 be perceived. In the other areas, the translucent carrier substrate 3 perceived in the area of the recesses 4a is not covered and in the laser-treated areas 6 with the now translucent front side layer after the laser treatment 4 is covered.

In 2d is a look through the laser-treated security element 2 B shown. Only the laser-treated areas are included 6 as areas of high translucency, that of the transmission of the carrier substrate 3 , while the non-laser-treated areas are perceived as regions of low translucency, whose translucency is due to transmission of the translucent carrier substrate 3 as well as the transmission of the front side layer 4 or the backside layer 5 results.

In the 3a is a second embodiment of a security element 2 shown in cross section. On a translucent carrier substrate 3 again is a fragmented front side layer 4 and a fragmented backside layer 5 arranged. In contrast to the first embodiment, however, overlap the job areas 4a . 5a from front side layer 4 and backside layer 5 in the overlapping areas 7 , The fragmented front side layer 4 and the fragmented backside layer 5 are thus arranged partially overlapping. In 3b the second embodiment is shown in transmitted light. This results in the areas 7 a low translucency, because in these areas the translucency of the transmission of the translucent carrier substrate 3 and the transmission of front side layer 4 and backside layer 5 While in the surrounding areas the translucency only depends on the transmission of the translucent carrier substrate 3 and the transmission of either the front side layer 4 or the backside layer 5 depends.

In the 4a to 4c is a third embodiment of a security element 2 shown. In 4a is for better understanding the structure of the security element 2 explained. It consists of different order areas 4a . 5a the front side layer 4 and the backsheet layer 5 that are arranged to complete, so that job areas 4a the front side layer 4 recesses 5b in the backsheet correspond and vice versa. There is still a motive 6 in two adjoining order areas 4a and 5a by Laser treatment introduced. In 4b the third embodiment is shown in transmitted light. The order areas complement each other 4a and 5a from the front side layer 4 and backside layer 5 to a see-through register in the form of the number "10". By the laser treatment, the front side layer 4 and the backside layer 5 Ablated in some areas, so that in this area results in an increased compared to the surrounding area translucency. Accordingly, in transmitted light, the motif generated by laser treatment 6 completely visible. In 4c is a view of the front of the security element 2 shown. When viewed in reflected light are only the order areas 4a the front side layer 4 recognizable. As the motive introduced by laser treatment 6 over a job area 4a and a recess 4b the front side layer 4 extends, is in supervision only a part of the subject 6 imperceptible.

In further embodiments, which correspond to the in 2a to 2d Ajar are the information applied on the front and back 4a and 5a as small solid surfaces or as rastered surface areas, eg. B. in the form of a dot or line grid realized. The applied on the front and / or back color may also contain components that can not be completely removed by laser, so that z. B. after the laser mark still a bright color remains. So z. B. a color mixture of Milori blue and a red pigment Red 146 are used, wherein after laser irradiation, the red pigment is maintained. In this way, hue differences associated with differences in transparency can be provided.

In a further embodiment, the element produced by printing technology may additionally contain a negatively omitted additional motif on the front and / or rear side, which disturbs the generated transparency information only insignificantly. This element may be ornamental accessory outside the laser-marked area or present within the laser-marked area and thereby further disturb the readability of the generated see-through information on the front and / or rear side in supervision. In case the additional element is outside the laser-marked area, the additional element may be a positive or negative motif.

Furthermore, the element produced by printing technology can additionally be equipped with a further security feature which does not or only insignificantly influences the laser marking. This can be z. B. be a luminescent and / or a magnetic feature substance. Likewise, the security element provided according to the invention can have an overprint of a visually transparent and transparent to the laser interference color. The overpressure can z. For example, Iriodine, such as coated with TiO ₂ mica or SiO ₂ pigments, or liquid crystal pigments.

According to the invention can be z. B. provide complete security features in which a part in the reflected light is visible or readable, and another part is recognizable or readable only in transmitted light. This is preferably possible by means of laser, since it can preclude the Passerschwankungen different process steps.

5a to 5c represent examples of real patterns of a security element according to the invention 5a is the supervisory information when looking from the front, in 5b the supervisory information when looking from the back, and in 5c the see-through information viewed from the front.
