- the first type of heat input into the thermochromic ink layer is, for example, a coupling of electrical energy, which heats an electrical resistance, so that a specific pattern is visible in the thermochromic ink layer.
- the second type of heat input takes place for example by body heat, such as a finger or the hand of a user, or by a large-scale heat source, such as a lamp or a radiant heater.
- the first information of the WO 2009/106242 A1 can still be individually edited or changed after application to the security element, so that an individual identifier can be generated.
- a thermochromic layer is applied over the entire area over a digit in the form of a customary 7-segment display, in which all segments are contacted in the ground state and connected to the electrical circuit.
- the number 8 appears in the case of electrical energy injection, and by selective separation of individual segments, all other numbers from 0 to 9 can be represented.
- the invention has the object of developing a method for producing a generic security element such that the protection against counterfeiting is further increased.
- the invention relates both to the production of value documents having the features according to the invention and to security elements which have the features according to the invention and which are produced independently in the form of a transfer element and transferred to a value document in a subsequent method step.
- a value document is, for example, a banknote, a security, a credit or identity card, a passport, a document or the like, a label, a packaging or another element for product assurance.
- the substrate particularly preferably consists of paper of cotton fibers or other natural fibers, and also preferably of synthetic fibers, ie a mixture of natural and synthetic fibers, or also preferably of at least one plastic film.
- the substrate consists of a combination of at least two superimposed and interconnected different substrates, a so-called hybrid, for example a combination plastic film-paper plastic film, ie a paper substrate is covered on each side by a plastic film, or paper Plastic film paper, ie a substrate made of a plastic film is covered on each side by a paper substrate.
- a so-called hybrid for example a combination plastic film-paper plastic film, ie a paper substrate is covered on each side by a plastic film, or paper Plastic film paper, ie a substrate made of a plastic film is covered on each side by a paper substrate.
- the term "arrangement of at least one display element” is generally understood to mean an area on the security element or value document that is occupied by at least one display element.
- This display element preferably consists of a surface which is formed in the form of a geometric figure, an alphanumeric character or a graphic image.
- the term "arrangement of display elements” is particularly preferably also understood to mean an accumulation of at least two display elements which are spatially or logically related to one another.
- the display elements are particularly preferably arranged in the form of a matrix, for example in the form of a square 2 ⁇ 2 matrix, a rectangular 2 ⁇ 3 matrix or generally in the form of a rectangular n ⁇ m matrix, where n and m are natural numbers.

- the display is applied to the front side of the substrate and, to this end, the further individual information on the back side of the substrate is held in register. For a viewer, both information for a total information complement each other.
- the individualization of the display results in several advantages. On the one hand results from the link with the other individual feature of the value document, a security feature that can be independently checked by a user as soon as the display is activated. Furthermore, this type of linkage can only be faked with greater technical and logistical effort. Particularly advantageous can be dispensed with an independent control unit for the display, such as a microprocessor or an integrated circuit, so that a cost-effective implementation is possible.
- the arrangement of the display elements in the form of a 7- or 14-segment display is executed.
- This embodiment has the advantage that it can be customized with little technical effort by disabling single or multiple segments. For example, in the case of a 7-segment display with electromagnetic excitation, the figure "8" appears.

- the display consists of an electrochromic printing ink whose color impression changes when an electric field is applied.
- one embeds with the electrochromic ink printed surface between printed surface elements, which consist of electrically conductive ink, so that there is a capacitor arrangement.
- the uppermost electrically conductive ink is preferably made transparent, e.g. indium tin oxide (ITO), fluorine tin oxide (FTO), aluminum zinc oxide (AZO), antimony tin oxide (ATO) or a conductive polymer, e.g. Poly-3,4-ethylenedioxithiophene doped with polystyrene sulfonate (PEDOT: PSS).
- bistable electrochromic printing ink as described for example in the journal " Smart Packaging Journal “July / August 2002 Vol 1, p 14-15 is described.
- the electrical voltage or the electromagnetic field must be applied only briefly to switch, the ink turns stable in a second state. Only at the next application of an electrical voltage or an electromagnetic field is the opposite color change.
- the display consists of an electroluminescent printing ink.
- an irreversible modification of the display is produced by switching off the electroluminescence at certain points or by processing the contact surfaces or supply lines of the electrical power supply for the electroluminescent printing ink.
- the display consists of an electrophoretic ink.
- the variant mentioned here at which are aligned by the application of an electrostatic field to the half-colored and the other half white balls and then an information is visible. Meanwhile, there are also colors that can be switched electrically in different color states. Even so, the described function can be realized.
- the irreversible modification of the arrangement of display elements by means of a laser or by means of mechanical ablation, wherein selectively at least one electrical line is severed by at least one display element and / or at least one display element is at least partially changed, deactivated or removed.
- a laser any other electromagnetic radiation source can be used with which layers can be removed or changed.
- a corrosive inkjet ink or a mechanical scraper targeted electrical lines to certain segments or points of the display are severed, so that appears in subsequent power supply, the desired information.
- unnecessary display elements are at least partially deactivated or activated by the laser, for example, by at least partially ablating the display element or physically or chemically changing the ink from which the display element is preferably made.
- the irreversible modification of the arrangement of display elements takes place by individual or multiple Display elements are at least partially overprinted with an ink.
- individual segments of the display are overprinted by conventional printing methods with a covering printing ink, for example, the pigment TiO 2 , or an absorbing ink, such as a complementary color to the color of the display or the color black, so as to customize the display.
- the irreversible modification of the arrangement of display elements by at least partially coated one or more display elements by, for example, overprinted, vapor-deposited or pasted over with film elements, and then a part of the coating is removed again, for example with a Laser.
- the coated display elements are thus partially uncovered, with the exposed areas forming the feature that is recognizably associated with at least one other individual feature of the security element or the value document.
- the irreversible modification of the display elements takes place by applying additional electrical lines for activating certain display elements, for example, which have not been previously or otherwise connected to electrical lines.
- embossing for example by means of a subsequent superimposed intaglio printing method and / or by partial overstretching and / or by punching and / or perforation to cut through an electrical line of at least one display element.
- an at least partially adapted to the laser wavelength used absorbent material is at least partially applied below at least one electrical line.
- an IR or UV absorber tuned to the laser wavelength for example in a primer, is applied under the conductor tracks, which leads to a better ablation of the part of the electrical conductor track which is acted on by the laser radiation.
- the distances between the respective electrical leads are preferably increased at least in partial areas of the display. This has the advantage that requirements for the registration accuracy of the individualization are reduced.
- the irreversible modification of at least one display element takes place in such a way that a feature of the display is thereby formed, which is recognizably associated with at least one further individual feature of the security element or the value document.
- the feature of the display is preferably associated with a serial number printed on a banknote on which the display is located.
- the information displayed here can be, for example, a check digit calculated from the serial number of a banknote or corresponds, for example, to the last digit of the serial number of the banknote.
- the individualized display shows a check digit, eg the first or last digit of the serial number of the banknote. This makes it possible to check the authenticity of the banknote even for untrained persons.
- the last digit may be replaced by a symbol, logo or pictogram repeated on the display. In this way, for example, nine different symbols can be switched.
- the display can be combined with optically variable colors that are printed in any layer of the display, but preferably across the display.
- optically variable colors that are printed in any layer of the display, but preferably across the display.
- colors with liquid crystal or interference pigments are suitable as optically variable colors.
- the individualized display is part of a serial number of the banknote.
- the display replaces one of the digits of the serial number, for example the last digit. Since the serial number is usually printed twice on a banknote, it is possible by direct comparison of the two serial numbers to check the authenticity of the bill in a simple manner.
- the individualized display represents a graphic image that is displayed on another area of the banknote.
- the display shows the same graphic image when activated, so that it can be compared directly by comparing the two Illustrations is possible to easily check the authenticity of the banknote.
- the individualized display represents a batch coding or a batch number.
- the individualized feature of the individualized display can be recognized in the visible wavelength range, in the infrared or in the ultraviolet wavelength range. In this case, the individualized feature can either be visually readable or recognizable by a viewer or machine-readable.
- the individualized feature is in the same language as the non-individualized alphanumeric characters, for example, as an Arabic numeral, or in another language, such as a Roman numeral, or as text, for example, the numeral "5" and the wording " five ", presented.
- Fig. 1 schematically shows a document of value in the form of a banknote 1 with two serial numbers 2 and 3, where serial number 2 shows the number "123456789” and serial number 3 shows only the first part of the serial number 2, namely the number "12345678".
- the missing last digit "9" is formed by a display 4, which consists of a 7-segment display, as exemplified in Fig. 2 is shown.
- the individual display elements of the 7-segment display show in their initial form the number "8".
- Display 4 is now irreversibly modified by the electrical line 7 is severed to display element 6, so that the corresponding display element can not light up when the display is supplied via the electrical line 5 with electrical energy.
- the display shows the digit "9" as soon as it is supplied with electrical energy and, in connection with serial number 3, has the same information content as serial number 2, since both show the number "123456789". This means that the display in connection with the part serial number 3 stands in a recognizable relationship to serial number 2.
- Example becomes in Fig. 3 a display 4 in the form of a 7-segment display described, which is connected to an electrical LCR resonant circuit.
- the LCR resonant circuit is formed here by the inductance L, the two capacitances C1 and C2 and the ohmic resistances of the display elements of the display 4.
- the LCR resonant circuit is acted upon from the outside with electromagnetic radiation whose frequency corresponds to the resonant frequency of the LCR resonant circuit , electrical energy is induced in the LCR resonant circuit and the display 4 is activated.
- the contacting with a resonant circuit on the security element or document of value only requires a rectifier diode, which is advantageously produced by printing technology in thin-film technology.
- a Optionally required counter-electrode for impedance matching can alternatively also be printed on the back of the substrate, or be designed as a film application. About the shape and arrangement of the electrodes can continue to structure the color change surface. This has the advantage that when contacting the display element in a sandwich structure (eg in electrophoretic or electrochromic display) the layers to each other need not necessarily be printed passerhaltig. The display only appears in outlines of the contacting electrodes or their superimposition.
- Fig. 4 shows a further embodiment of the display 4, in which a number is formed by a continuously printed area.
- Display 4 is hereby irreversibly modified by separating certain parts of the printed area from the remaining part, so that any desired number can be displayed.
- Activation of display 4 takes place, for example, by the display 4 being supplied with electrical energy via galvanic coupling to the electrical contacts 8 and 9, the electrical lines 8a and 8b and also 9a, 9b and 9c being modified to the display 4 depending on the digit to be displayed , ie can be severed.
- Fig. 5 shows a further embodiment of the display 4, in which a number is formed by a full-surface printed area.
- Display 4 is hereby irreversibly modified by removing certain parts of the printed area. This not only any number can be displayed, but the digit can also be configured in any shape, for example, in a curved or nörkelten shape.
- An activation of the display 4 takes place, for example, by supplying the display 4 with electrical energy via galvanic coupling to the electrical contacts 8 and 9.
- the display 4 can be printed or transmitted as a patch. This applies in particular to displays based on OLED or electroluminescent printing inks.
- the resonant circuit and the printed conductors for the display can be printed, for example by means of screen, offset, gravure, intaglio, or ink-jet printing processes, as a patch with an already completely prefabricated design, or by embossing processes, such as hot or cold foil embossing, for example. be generated.
- Electrically conductive materials may consist of a foil application of aluminum, copper, silver, gold or electrically conductive polymers.
- Printing inks may contain as electrically conductive substances, for example, silver ground, silver colloids, gold colloids, carbon nanotubes, graphene, carbon black / graphite, ITO, etc.
- the display, the printed conductors as well as the resonant circuit can be partially overprinted or covered with a patch.
- the conductor tracks and the resonant circuit it is also possible to encase this in the substrate with.
