Definitions

  • the invention relates to a security element which has at least one thermochromic ink layer.
  • the thermochromic ink layer covers a first information, so that the first information is not recognizable. Only with a first type of heat input into the thermochromic ink layer is the first information recognizable.
  • a generic security element in which electronic components in the form of at least one LCR resonant circuit are provided in or on a value and security document.
  • the LCR resonant circuit is in this case an electrical resonant circuit consisting of a coil with the inductance L, a capacitor with the capacitance C and an ohmic resistance R.
  • An electromagnetic radiation source for example an RFID reader or a simple transmitter, excites the LCR resonant circuit where heat is produced by specific power dissipation and determined directly or via a specific indicator reaction.
  • the specific indicator reaction takes place, for example, by a color change of a thermochromic ink layer inside and / or on the surface of the value and security document.
  • thermochromic ink layer is so slow that it can not be used in current banknote processing machines with processing speeds of up to 40 banknotes per second.
  • Such other heating may be, for example, a heat conduction via the hand, a radiation absorption of a lamp or an increased ambient temperature. Even if a heat conduction over the hand and an increased ambient temperature due to eg a color change temperature of eg + 45 ° C can be excluded, is due to capacitive effects, such as pollution and the nature of "in-hand-holding" of the security element, and Resistive effects due to creasing the exact resonant frequency and thus the absorbed energy of the LCR resonant circuit can not be determined. Thus, the warming and the associated proof of authenticity is uncertain.
  • thermochromic layer by means of an electrical heating element takes place.
  • This heating element is formed by a patterned resistive layer, which may consist of a plurality of separately controllable heating elements.
  • thermochromic layer is combined with an effect layer which has visually and / or machine-testable properties.
  • effect layers may be, for example, special luminescent or magnetic substances which are mixed, for example, with an ink.
  • the invention is therefore the object of developing a generic security element such that the disadvantages of the prior art is eliminated and the protection against counterfeiting is further increased.
  • the security element has an electrical circuit which has an ohmic resistance, wherein the thermochromic ink layer is arranged above the ohmic resistance. Furthermore, over the thermochromic ink layer, an optically variable ink layer is printed, which has polarizing liquid crystal pigments.
  • thermochromic ink layer covers a second information in addition to the first information.
  • the second information is not visible in a certain temperature range, for example, at the usual ambient temperature or at room temperature. Only when a second type of heat input, which is preferably different from the first type of heat input, takes place in the thermochromic ink layer is the second information recognizable.
  • a color change occurs in a different geometric distribution or geometrical pattern than in the second type of heat input.
  • thermochromic ink layer changes, and this particular one Area is particularly preferably executed in the geometric shape of a pattern, an alphanumeric character or an image.
  • the contour of this particular area forms the first information.
  • thermochromic ink layer In the second type of heat input, for example, when heated by a finger or a lamp, however, changes the entire surface of the thermochromic ink layer, which is exposed to the heating.
  • the second information is formed either by the outline contour of the surface having the color change, or additionally in a thermochromic color transition from color to colorless or transparent by a lying under the thermochromic ink layer printed image.
  • This print image is executed within the contour of the warming finger or light cone in the form of a pattern, an alphanumeric character or an image, for example as an arrangement of " €" symbols.
  • the first and second information preferably have a different information content, wherein the first and second information can be arranged directly above one another or against each other.
  • the first information may be a text or a number
  • the second information may be a colored area of an oval outline.
  • a different information content within the meaning of this invention is also present if the first and second information represent the same text, the same number, the same pattern, etc., but the respective elements have different sizes or different colors, or are rotated or shifted relative to one another.
  • the first and second information have the same information content.
  • the first and second information must be at different locations on the security element be arranged or may overlap only partially, otherwise the first and second information would have the same information content.
  • the first and second information each represent the number "50" in the same size, same font and color, but are more or less rotated against each other or arranged so that they are not congruent or not directly superimposed.
  • thermochromic ink layer may cover at least one other piece of information that is also not recognizable.
  • This further information can be recognized only in a further type of heat input into the thermochromic ink layer, which is different from the first and second type of heat input.
  • a particular advantage is that three or more pieces of information, which either have the same information content at different locations or different information contents, can be "hidden" in the security element, whereby the protection against counterfeiting is further increased.
  • the invention comprises both a substrate with a security element and a data carrier with a substrate with a security element.
  • the data carrier is in particular a value document, such as a banknote, a security, a credit or identity card, a passport, a document and the like, a label, a packaging or another element for product assurance.
  • At least one information is arranged on one side of the substrate and at least one thermochromic color layer on the opposite side of the substrate. The heat transfer takes place through the substrate or security element.
  • thermochromic ink layer on the opposite side of the substrate, so that the counterfeit protection further increases. This is especially true if both the information and the thermochromic ink layer are integrated in the design of the security element or of the data carrier or in another security element.
  • the security element has at least one electrical circuit.
  • the electrical circuit in this case has at least one ohmic resistance, which is designed in the form of a pattern, an alphanumeric character or an image, wherein the thermochromic ink layer at least partially covers the ohmic resistance.
  • the ohmic resistances thus have the task of a heating element. They are arranged in a matrix arrangement or any outline shape, for example in the form of the number "50”, and overprinted with the thermochromic ink layer and thus hidden. Upon electrical excitation, the ohmic resistors heat the thermochromic ink layer, so that within the thermochromic ink layer, a different colored or transparently formed number "50" appears, corresponding in their shape and area of the number formed by the ohmic resistors number "50".
  • the electrical excitation takes place in an embodiment of the electrical circuit as an open circuit by direct galvanic contact with an electrical energy source.
  • this galvanic contact is made by contact between a battery and the electrical circuit.
  • the electrical excitation is preferably contactless via the coupling of electromagnetic radiation and more preferably via magnetic-inductive coupling of a field in the radio frequency range (RF).
  • the resonant frequency of the LCR resonant circuit or operating frequency of the corresponding transmitting antenna is preferably in the range of 1 MHz to 1 GHz, preferably in the range of 5 MHz to 30 MHz and more preferably in the range of 13.56 MHz or 27 MHz.
  • the total resistance of the LCR resonant circuit is preferably in the range of 100 ⁇ to 1 k ⁇ , more preferably in the range of 150 ⁇ to 500 ⁇ , of which the majority, preferably more than 70% and more preferably more than 90%, the ohmic resistances ,
  • the electrical circuit is also possible to form the electrical circuit as a film application in the form of a security label, a so-called patch, or security strip and then transferred to a substrate.
  • the individual ohmic resistors are preferably connected in parallel.
  • the ohmic resistors connected in parallel are supplemented by further ohmic resistors connected in series, so that a greater bandwidth of the responsiveness can initially be realized and also visualized by these resistors in a preferably different size and thus different power class.
  • suitable dimensioning can be achieved both a local, as well as time-resolved color change.
  • a resistance that "migrates" via the ohmic resistances results. Color change of the thermochromic ink layer. First, the first ohmic resistance heats up, then the next, etc.
  • the triggering speed of a heating element is dependent on its area or the heat capacity and the ohmic resistance and the difference between their trip temperature and the ambient temperature. For example, color changes more slowly in a larger element than in a smaller element; if the area is the same, an element with a large ohmic resistance triggers faster than with a low resistance element, as long as the elements are connected in series. With parallel connection it is vice versa.
  • a suitable design can be used to create a movement effect.
  • thermochromic layers of paint which have the same or different patterns, are printed one above the other on the electrical circuit, with the bottom, e.g. a transition temperature of + 50 ° C and the overhead e.g. of + 25 ° C.
  • thermochromic color layer In the case of an assumed color change of the underlying thermochromic color layer from green to blue and the upper thermochromic color layer from black to colorless, a color change from black to green occurs with thermal excitation by a finger and with electric stimulation with a greater energy input from black to blue , In the case of mixtures of thermochromic colors, it is thus also possible to achieve temporal / thermal continuous color transitions.
  • thermochromic liquid crystal pigments on a simple black background, rainbow colors appear depending on the current temperature.
  • time-varying colored images / patterns can be generated. Further explanations are in DE 10 2006 016 048 specified.
  • thermochromic ink in the ground state at ambient or ambient temperature is used as the upper visible layer
  • an additional overprinting of a polarizing effect ink, as used in US Pat DE 10243650 A1 or WO 2004028824 A2 is described.
  • the black surface is aesthetically resolved
  • the polarization of the reflected light is an additional safeguard.
  • a particular advantage of the invention arises when in the near future RFID labels will increasingly find use also on individual retail packaging.
  • corresponding RFID readers at checkout terminals will be as common as nowadays barcode scanners or UV lamps for authentication of banknotes.
  • all banknotes of a banknote or plant stack are excited by radio frequency irradiation and then the thermochromic color change of each individual banknote is evaluated by machine.
  • Fig.1 shows a banknote or a chip card, which consists of a substrate 1, on which a thermochromic ink layer 2 is applied in the form of an oval surface.
  • the thermochromic ink layer 2 In the ground state, ie at room or ambient temperature, the thermochromic ink layer 2 is opaque and has a certain color, for example green. If a viewer places a finger on the thermochromic ink layer 2, changes accordingly 1b shows the corresponding area 3 its opacity and is colorless, so that the lying under the thermochromic ink layer 2 substrate 1 is visible. If an imprint in the form of several " €" symbols is present on the substrate 1, then Fig. 2a the arranged in area 3 " €" symbols 6 visible.
  • thermochromic ink layer 2 is irradiated by a large-area heat source, the entire region 4 of the thermochromic ink layer 2 changes its opacity and becomes colorless. This results in a transparent oval surface, in accordance with Fig. 1c the surface of the substrate 1 or according to Fig. 2b the arranged in this area " €" symbols 7 are visible.

Now, if electrical energy is coupled into the electrical circuit, the ohmic resistors heat up, so that in a region 5, the thermochromic ink layer 2 changes its color from green to transparent. Thus, within the green thermochromic ink layer 2, a transparent region 5 in the form of the number "50" appears.
  • the region 5 of the thermochromic ink layer 2 in this case corresponds to the first information according to the invention.
  • Fig. 3 shows an embodiment of the electrical circuit in the form of an open circuit with galvanic energy coupling.

  • the electrical resonant circuit consists of a coil with the inductance L, a Capacitor with the capacitance C and ohmic resistors Ri.
  • the capacitor is preferably designed as an additional conductive surface elements and / or as a hologram patch, so that the capacitor can be advantageously designed as another located on the banknote security element.
  • the heating resistor is formed as a series circuit of five individual ohmic resistors R1 to R5, wherein the resistance value from the ohmic resistance R1 to the ohmic resistance R5 decreases steadily, ie R1>R2>R3>R4> R5 (the resistance of the ohmic resistance R1 is greater than that of the ohmic resistance R2, that of the ohmic resistance R2 is greater than that of the ohmic resistance R3, that of the ohmic resistance R3 is greater than that of the ohmic resistance R4 and that of the ohmic resistance R4 is greater than that of the ohmic resistance R5).
