Description

The invention relates to a data carrier, in particular a value or security document, with a plurality of spaced window areas. The invention also relates to a method for producing such a data carrier.

Data carriers, such as banknotes, shares, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other papers at risk of forgery, such as passports or other identification documents, are often provided with security elements for security purposes, which allow the authenticity of the valuable document to be checked and at the same time serve as protection against unauthorized reproduction.

In this context, it is known to design security elements in the form of a window security element that is completely or partially embedded in a banknote, for example in the form of a window security thread that is visible on one or both opposite surfaces of the banknote in certain window areas. Although such window security elements ensure good security of the data carriers provided with them, there is a need to further improve the visual appearance and the anti-counterfeit protection of data carriers secured in this way.

This task is solved by the features of the independent claims. Further developments of the invention are the subject of the dependent claims.

The invention provides a data carrier, in particular a value or security document, with a plurality of spaced window areas, each of which has a security feature with an optically variable effect. The data carrier also has intermediate areas without a visually variable appearance, which separate the window areas mentioned from one another.

Different information is displayed in the several window areas and the optically variable security features of the several window areas produce different dynamic effects.

The optically variable security features preferably produce the different dynamic effects of the window areas when the data carrier is tilted about different axes.

The different axes for generating the different dynamic effects advantageously include angles that are an integer multiple of 45° or an integer multiple of 60° or an integer multiple of 90°.

For example, two different tilting axes can be provided for generating different dynamic effects, which are perpendicular to one another, i.e. enclosing an angle of 90°. In another example, three different tilt axes are provided for generating different dynamic effects, with the second axis rotated by 60° relative to the first axis and the third axis rotated by 60° relative to the second axis. All intermediate angles are then 60° or 120°, i.e. they are an integer multiple of 60°. In a further example, four different tilt axes are provided for generating different dynamic effects, with the second axis rotated by 45° relative to the first axis, the third axis rotated by 45° relative to the second axis and the fourth axis rotated by 45° relative to the third axis is. All intermediate angles are then 45°, 90° or 135°, i.e. they are an integer multiple of 45°.

• - beim Kippen des Datenträgers um eine erste Achse in einem ersten Fensterbereich ein dynamischer Effekt erzeugt wird, während in einem zweiten Fensterbereich kein dynamischer Effekt sichtbar ist, und dass
• - beim Kippen des Datenträgers um eine zweite, unterschiedliche Achse in dem ersten Fensterbereich kein dynamischer Effekt sichtbar ist, während in dem zweiten Fensterbereich der oben genannte dynamische Effekt des ersten Fensterbereichs beim Kippen um die erste Achse erzeugt wird.

In an advantageous embodiment it is provided that

• - When the data carrier is tilted about a first axis, a dynamic effect is created in a first window area, while no dynamic effect is visible in a second window area, and that
• - When the data carrier is tilted about a second, different axis, no dynamic effect is visible in the first window area, while in the second window area the above-mentioned dynamic effect of the first window area is generated when tilting about the first axis.

In this embodiment, when the tilting direction changes, the same dynamic effect appears once in the first window area and once in the second window area, while the other window area shows no dynamic effect. The dynamic effect therefore appears to the viewer to “jump” when the tilt direction changes from one window area to another window area. The first and second axes are advantageously perpendicular to one another, but can generally also include a different angle, for example 45° or 60°.

• - beim Kippen des Datenträgers um eine erste Achse in einem ersten Fensterbereich ein erster dynamischer Effekt erzeugt wird und in einem zweiten Fensterbereich ein zweiter, unterschiedlicher dynamischer Effekt erzeugt wird, und dass
• - beim Kippen des Datenträgers um eine zweite, unterschiedliche Achse in dem ersten Fensterbereich der zweite dynamische Effekt erzeugt wird und in dem zweiten Fensterbereich der erste dynamische Effekt erzeugt wird.

In another advantageous embodiment it is provided that

• - When the data carrier is tilted about a first axis in a first window area, a first dynamic effect is generated and in a second window area, a second, different dynamic effect is created, and that
• - When the data carrier is tilted about a second, different axis, the second dynamic effect is generated in the first window area and the first dynamic effect is generated in the second window area.

In this embodiment, the two dynamic effects swap places when the tilting direction changes. The first and second axes are advantageously perpendicular to one another, but can generally also include a different angle, for example 45° or 60°.

In an advantageous embodiment, the dynamic effects each include a movement effect and/or a color change effect. In a particularly preferred embodiment, the optically variable security features of the window areas each produce different movement effects.

The movement effect generated by a window area can be a linear movement effect with rectilinear movement behavior, a radial movement effect, a cyclic movement effect, in particular with a rotational movement clockwise or counterclockwise, or also a non-linear movement effect. The movement that the viewer can perceive can also be back and forth, for example in a zigzag path, or chaotic, like a random movement.

Alternatively or additionally, the dynamic effects may include a zoom effect, a morphing effect, an image change effect, a pump effect and/or a pseudo-3D effect. The latter show spatial depth and appearances that appear to float above or below the disk and appear to move relative to the surface of the disk when the disk is tilted.

In the context of the description, the tilting directions are sometimes referred to as north-south tilting or west-east tilting, with the upper side of a data carrier lying in front of a viewer, like a map, being the upper side as north, the lower side as south, and the left side as West and the right side is called East.

Two or more different dynamic effects are advantageously combined in the window areas, for example a movement effect and a color changing effect or a color changing effect and a morphing effect, so that a particularly complex appearance is created.

In an advantageous embodiment, microlenses, micromirrors, nanostructures and/or hologram structures are provided in the window areas to generate the dynamic effects.

To create a color changing effect, thin-film elements, liquid crystals, optically variable pigments, thin color-shifting pigments, a double-color structure arranged on two different levels, a high-index coating, a microlens arrangement with differently colored microstructures, a microlens arrangement with different nanostructures and/or are advantageously used in the window areas. or diffractive azimuthal color shift structures are provided.

In a preferred embodiment, at least two window areas show dynamic effects, in particular movement effects, which show the same movement behavior when the data carrier is tilted about a first axis and show opposite movement behavior when the data carrier is tilted about a second, different axis. The second axis is preferably perpendicular to the first axis.

The security features are arranged in particular in a registered manner in the window areas. Furthermore, independent information is displayed in the window areas. In particular, the information in the window areas does not simply represent excerpts from the same overall information, for example an image or graphic.

In an advantageous variant of the invention it is provided that the data carrier comprises a data carrier substrate with a partially embedded security element that is partially visible on the surface of the data carrier substrate and that the window areas are formed by the partial areas of the security element that are visible on the surface of the data carrier substrate.

The partially embedded security element advantageously only has security features in the window areas, so the security features are arranged on the security element registered to the window areas.

The security element is preferably a security thread, in particular a window security thread visible on at least one surface of the data carrier substrate or a pendulum security thread visible on both opposite surfaces of the data carrier substrate.

According to an advantageous development of the invention, the security element, in particular the security thread, designed to be machine readable. For this purpose, it has in particular magnetic feature substances, fluorescent feature substances, phosphorescent feature substances, IR-absorbing feature substances, THz structures and/or a metallization with demetallized areas in the form of negative markings. The negative identifiers can in particular form an alphanumeric character string.

In another, also advantageous variant of the invention, it is provided that the data carrier has a data carrier substrate with an opaque cover layer and the window areas are formed by spaced recesses in the opaque cover layer.

The data carrier can in particular be a document of value or an identification card, but it can also represent a security element, in particular a security thread, security strip, a transfer element or a label.

In an advantageous development of the invention, the information displayed in the window areas is combined with an additional security feature arranged on the data carrier, the information content of which is related to the information in one of the window areas. The additional security feature is in particular a different type of security feature, i.e. does not represent a window area, but is formed, for example, by a watermark, a security print area or a transfer element. The hedging effect is further increased by such a combination with a different type of security feature.

• - ein Datenträgersubstrat bereitgestellt wird und mit einer Mehrzahl von beabstandet angeordneten Fensterbereichen und mit die Fensterbereiche voneinander trennenden Zwischenbereichen versehen wird, wobei die Fensterbereiche jeweils mit einem Sicherheitsmerkmal mit einem optisch variablen Effekt versehen werden, und die Zwischenbereiche ohne optisch variables Erscheinungsbild ausgebildet werden, wobei
• - die Sicherheitsmerkmale in den Fensterbereichen so ausgebildet werden, dass in den mehreren Fensterbereichen jeweils unterschiedliche Informationen angezeigt werden und die optisch variable Sicherheitsmerkmale der mehreren Fensterbereiche jeweils unterschiedliche dynamische Effekte erzeugen.

The invention also contains a method for producing a data carrier of the type described, in which

• - a data carrier substrate is provided and is provided with a plurality of spaced window areas and with intermediate areas separating the window areas from one another, the window areas each being provided with a security feature with an optically variable effect, and the intermediate areas being formed without an optically variable appearance, wherein
• - The security features in the window areas are designed in such a way that different information is displayed in the multiple window areas and the optically variable security features of the multiple window areas each produce different dynamic effects.

Further exemplary embodiments and advantages of the invention are explained below with reference to the figures, which are not reproduced to scale and proportions in order to increase clarity.

• 1 in schematischer Darstellung eine Papierbanknote mit einem teilweise in das Banknotenpapier eingebetteten Fenstersicherheitsfaden,
• 2 den den Fenstersicherheitsfaden enthaltenden Teilbereich der Banknote der 1 genauer, und
• 3 einen Teilbereich eines Datenträgers mit vier beabstandet angeordneten Fensterbereichen nach einem weiteren Ausführungsbeispiel der Erfindung.

Show it:

• 1 a schematic representation of a paper banknote with a window security thread partially embedded in the banknote paper,
• 2 the portion of the banknote containing the window security thread 1 more precisely, and
• 3 a partial area of a data carrier with four spaced window areas according to a further exemplary embodiment of the invention.

The invention will now be explained using banknotes as an example. 1 shows a schematic representation of a paper banknote 10 with a printing element 14 applied to the banknote paper 12, a watermark 16 generated during paper production and a window security thread 18 partially embedded in the banknote paper.

The window security thread 18 emerges in spaced window areas 20 on the surface of the banknote 10, while it is embedded in the web areas 22 in between in the interior of the banknote 10.

The portion of the banknote 10 containing the window security thread 18 is in 2 presented again in more detail. The window security thread 18 of the exemplary embodiment contains three window areas 20A, 20B, 20C, in each of which a security feature 24A, 24B or 24C with an optically variable effect is arranged, registered to the window outline.

The security features 24A, 24B, 24C each show different information, which is represented in the figure by the letters “A”, “B” and “C”. The information displayed in the window areas 20A-20C is each independent information, and is therefore in particular not simply excerpts from overall information covering the entire thread 18.

In addition to displaying different information, the security features 24A, 24B, 24C of the window areas also produce different dynamic effects. For example, when the banknote is tilted 28 for a viewer, the information “A” represented by the security feature 24A moves in the direction 26A parallel to the longitudinal direction of the thread, which is represented by the security feature times 24B shown information "B" in direction 26B perpendicular to the longitudinal direction of the thread, and the information "C" represented by the security feature 24C in direction 26C oblique to the longitudinal direction of the thread. The movement effects 26A-26C, which differ in the direction of movement, can additionally be combined with the same or different color changing effects.

The window areas 20A, 20B, 20C are separated from each other by mere paper bars 22, which do not have an optically variable appearance and therefore provide a visual contrast and a visual calm for the optically variable appearances of the window areas 20A-20C.

Since the window areas 20A-20C not only show different information "A", "B" and "C", but also present this information with different dynamic effects 26A, 26B, 26C, the banknote 10 offers an attractive, complex and therefore only Difficult to recreate appearance with high attention and recognition value.

3 shows another embodiment of the invention, which illustrates further possibilities for the complex appearance of the optically variable window areas of a data carrier according to the invention. The figure shows a partial area of a data carrier 30 with four spaced window areas 40, 50, 60 and 70. The window areas 40, 50, 60, 70 can be part of a window security thread embedded in a data carrier substrate, but they can also be areas of a Polymer or film composite banknotes, which are separated from each other by suitable overprinting of the surrounding areas and the web areas and only create the visual impression of an applied elongated thread.

The first window area 40 shows, as an optically variable element, a sun 42 with rays 44, which move radially outwards or inwards for a viewer when the data carrier is tilted 28, as indicated by the arrows 46.

In all designs, the information displayed in the window areas can be combined with a further security feature arranged on the data carrier, the information content of which is related to the information in one of the window areas. For example, the sun symbol 42, 44 of the window area 40 can be combined with a watermark 48 in the form of a cloud, which is arranged next to the window area 40 on the data carrier. An additional security feature can also supplement the information of the window area to form overall information, for example a window area can contain the number “20” as information and a print element arranged next to the window area can contain the currency “€”. Another possibility is that one pane contains part of a number, such as a serial number, and the adjacent disk pane contains the rest of the serial number. The two pieces of information can only complement each other to form the correct, desired overall information when viewed from a specific viewing direction.

The second window area 50 contains a true color hologram in the form of a portrait 52, in which, in addition to its optically variable appearance, a dynamic effect is realized by the movement of the eyes 54. When the data carrier is tilted 28, the person's eyes 54 appear to move from left to right, as indicated schematically by the arrow 58 in the detailed representation 56 of the eyes. The portrait of the window area 50 is advantageously repeated in another area of the data carrier 30, for example in a print motif or a portrait watermark, such as the watermark 16 of the 1 .

The window area 60 contains the number “50” (reference number 63) and the currency information “€” (reference number 64) as optically variable information elements, with the two elements 62, 64 moving orthogonally to one another when the data carrier is tilted 28, as shown by the movement arrows 66 , 68 displayed.

Finally, the window area 70 contains a control wheel 72 as an optically variable element, which rotates about its axis when the data carrier is tilted 28, as indicated by the rotation arrows 74. When the tilting direction 28 changes, the direction of rotation of the control wheel 72 also changes.

How out 3 As can be seen, the window areas 40, 50, 60, 70 each contain independent information (sun symbol, portrait, denomination, steering wheel), which is also arranged in register with the window outline. The window areas also show different dynamic effects, specifically different movement effects. These different movement effects can also be combined with the same or different color changing effects.

The window areas 40, 50, 60, 70 are each separated from one another by intermediate areas 80 without an optically variable appearance. The intermediate areas 80 can, for example, represent mere paper webs of a paper substrate or printed areas of a paper, polymer or hybrid banknote.

The window areas do not have to be arranged linearly one behind the other, as shown in the previous exemplary embodiments for the sake of simplicity. For example, in another design variant, a data carrier may contain a central window area and a plurality of spaced outer window areas surrounding the central window area. The central window area can, for example, show a silver-colored arching effect and the outer window areas each have a color-shifting effect, with the color-shifting effects of the outer window areas each having different tilting axes.

In another design variant, the spaced window areas show a running effect that continues across the window areas when the data carrier is tilted, with the directions or type of dynamic effects in the window areas differing.

Another design variant contains a light spot image with different information content and different movement behavior as an optically variable security feature in the window areas. For example, a first window area shows a west-east movement when the data carrier is tilted north-south, while a second window area shows a north-south movement when the data carrier is tilted west-east. Such light spot images can be generated, for example, by micromirror arrangements, diffractive structures or by microFresnel lenses.

The movement effects can also occur when tilting around two axes, with the movement then running in different directions in the different window areas. For example, a parallactic and orthoparallactic movement of the light spots can be generated alternately as a dynamic effect in successive window areas, so that, for example, when the data carrier is tilted north-south, a north-south movement is shown in a first window area (parallactic movement), a west -East movement in a second window area (orthoparallactic movement), in a third window area a north-south movement is visible again and so on. When the data carrier is tilted west-east, the first window area then shows a west-east movement, the second window area shows a north-south movement, the third window area again shows a west-east movement and so on.

In a further design variant, the window areas can each show a tilting image between motifs that match in different viewing directions. For example, when the data carrier is tilted, a first window area shows a change from a motif A to a motif B, a second window area shows a change from motif B to a motif C and a third window area shows a change from motif C to motif A (or another motif D ). The motif change can also take place in different ways with different tilting directions.

Another design variant contains a central window area and two side window areas arranged on either side of the central window area. In addition to different information, the side window areas also show a dynamic movement effect that is orthogonal to the central window area.

In a further, particularly advantageous embodiment, two window areas each show dynamic effects, which show the same movement behavior when the data carrier is tilted about a first axis and show opposite movement behavior when the data carrier is tilted about a second, different axis. The two axes are in particular perpendicular to one another.

For example, in the case of a rotation effect, the security features of the window areas can rotate with the same direction of rotation when the data carrier is tilted north-south, while they rotate in the opposite direction of rotation when the data carrier is tilted west-east.

With a zoom effect, the security features of the window areas can all increase or all decrease when the data carrier is tilted north-south, while when the data carrier is tilted west-east, the security features of a first window area increase (or decrease) and the security feature conversely reduce (or enlarge) a second window area.

In the case of a radial movement effect, the security features of the window areas can all run equally outwards or inwards when the data carrier is tilted north-south, while they run outwards or inwards in opposite radial directions when the data carrier is tilted west-east.
