Description
The present invention relates to a kind of security element, it comprises the chromatograph of at least one thermochromism.The chromatograph of this thermochromism covers a first information, thereby this first information can not be recognized.Only when heat adds in the chromatograph of thermochromism by first kind of mode, just can see the described first information.
By the known security element by type of the present invention of EP 1,320 836 A2, wherein, within value document and the secure file or on the electronic chip that is at least LCR oscillation circuit form is set.At this, the coil that the LCR oscillation circuit is L by an inductance, a capacitor and the electric oscillation loop that Ohmage R forms that electric capacity is C.Electromagnetic radiation source, for example RFID (radio-frequency (RF) identification) reading machine or simple transmitter encourage described LCR oscillation circuit, at this, produce heat by special loss power, and directly or by special indicant reaction know.Described special indicant reaction for example passes through at value document and secure file is inner and/or the colour switching of the chromatograph of lip-deep thermochromism realizes.
Yet this security element is not suitable as machine-readable mark.The colour switching of the chromatograph of thermochromism is carried out so slowly, so that it can not reach in current commonly used processing speed in the bank note processing machine of 40 banknotes p.s. and uses.
More important disadvantages is, can't distinguish is because the electromagnetic radiation that has absorbed by the RFID reader antenna causes heating or color conversion, the still heating of being undertaken by other approach.The heating of other approach can for example be the heat conduction by hand, the radiation of absorption modulation, or the environment temperature that raises.Even if since for example the color conversion temperature for for example+45 ℃ the environment temperature of importing heat and rising by hand into can being foreclosed, but because the capacity effect that for example mode contaminated and that security element " is held in the hand (In-der-Hand-Haltens) " causes by security element, and the electricresistance effect that causes by fold (Verknitterung), and can not determine LCR oscillation circuit resonance frequency accurately, and thereby can not determine the energy of its absorption.Therefore heating and associated authenticity prove insecure.
Therefore technical matters to be solved by this invention is, so further improvement is by the security element of described type, so that overcome the shortcoming of prior art and further improve anti-counterfeiting performance.
This technical matters solves by the feature of independent claims.Further improvement of the present invention is the technical theme of dependent claims.
By the present invention, the chromatograph of described thermochromism additionally covers one second information except that covering the first information.This second information also can not recognize in certain temperature range, for example under the common environment temperature or in room temperature the time.Only heat by the chromatograph of the preferred second kind type of heating adding thermochromism different with first kind of type of heating in the time, just can see described second information.
Therefore by the present invention, when heating by first kind of mode, color conversion is carried out with geometric distributions different when heating by the second way or different geometric schemes.
Therefore, when heating by first kind of mode, have only certain zone of the chromatograph inside of thermochromism to change, wherein, described zone particularly preferably is designed to the geometric configuration of pattern, alphanumeric symbol or image.The profile in described certain zone constitutes the described first information.
Otherwise by the second way heating time, during for example by finger or lamp heating, the surface of the chromatograph of whole thermochromism of being heated changes.At this, the appearance profile on second information or the surface by turn colors constitutes, or additionally constitutes by the printing figure below the chromatograph that is in thermochromism from coloured color conversion to colourless or transparent thermochromism the time.Described printing figure is the form of pattern, alphanumeric symbol or image at the finger of heating or the indoor design of light cone profile, for example is designed to symbol
Structure.
Described first and second information preferably have the different information contents, and wherein first and second information can be arranged directly stacked or each other with offsetting.Therefore for example the first information can embody literal or numeral, and second information presents the coloured surface of cartouche shape.The different within the scope of the invention information contents also comprise, although the identical literal of first and second information statement, identical numeral, identical pattern etc., unit have different sizes or different color or rotates each other or layout with interlacing separately.
Alternatively, first and second information also can have the identical information content.But in this case must be with first and second information placement different position on security element, or only allow to overlap, because otherwise first and second information will have the identical information content.For example first and second information show identical, font the is identical numeral " 50 " identical with color of size respectively, but they rotate or layout more or less each other with interlacing, thereby make them incomplete same or directly do not arrange stackedly.
Except that first and second information, the chromatograph of described thermochromism can additionally cover another information at least, and it can not be recognized equally.Described another information only can see that just described another kind of type of heating is different with second kind of type of heating with first kind when heat adds in the chromatograph of thermochromism alternatively.The advantage that obtains thus giving prominence to is, can " hide " three or more information in described security element, itself or have the identical information content in the different location, or have the different information contents, further improve anti-counterfeiting performance thus.
The present invention not only relates to the substrate with security element, and relates to and have a data carrier that comprises the substrate of security element.At this, data carrier is value document especially, and for example banknote, security, credit card or certificate, passport, proof document and so on, label, packing or other are used for the element of product safety.
By a kind of optional form of implementation, at least one information is located at a side of substrate, and the chromatograph of at least one thermochromism is located on the opposite side of substrate.In this case, pass substrate or security element heats.The advantage of doing like this is, potential fake producer can't discern the relation between the chromatograph of information on substrate one side and the thermochromism on the substrate opposite side, thereby further improves anti-counterfeiting performance.If especially the chromatograph of information and thermochromism all is integrated in the design of security element or data carrier or in another security element, can further improve anti-counterfeiting performance.
Especially, described security element has at least one circuit, and at this, described circuit has at least one Ohmage that is designed to the form of pattern, alphanumeric symbol or image, and wherein, the chromatograph of described thermochromism covers this Ohmage at least in part.Therefore when input electric energy in circuit, only the chromatograph of thermochromism is arranged in above the Ohmage or is close to the domain transformation color of Ohmage.The chromatograph inside that is implemented in thermochromism thus can be seen part pattern, alphanumeric symbol or the image of Ohmage at least.
Therefore Ohmage is born the task of heating element.They are pressed matrix structure or arrange with any contour shape, for example are the shape of numeral " 50 ", and with the chromatograph covering of thermochromism and thereby by hidden.When electric excitation, Ohmage is the heating of the chromatograph of thermochromism, thereby presents another kind of color in the chromatograph inside of thermochromism or become transparent numeral " 50 ", it on its shape and area with consistent by the numeral " 50 " of Ohmage formation.
When circuit design was the circuit of non-closure, described electric excitation was by contacting realization with the direct electric current of power supply.The contact of for example described electric current is by the realization that contacts between battery and the circuit.
For be the closed circuit of oscillation circuit or LCR oscillation circuit in form, electric excitation is preferably realized with particularly preferably being coupled by the magnetic induction in radio-frequency band (RF) internal field by the electromagnetic radiation coupling non-contiguously.The resonance frequency of LCR oscillation circuit or the frequency of operation of respective transmit antenna preferably are in 1MHz to the 1GHz scope, preferably in 5MHz to 30MHz scope, and particularly preferably in the scope of about 13.56MHz or about 27MHz.The all-in resistance of LCR oscillation circuit preferably is in 100 Ω to the 1K Ω scopes, particularly preferably in the scope of 150 Ω to 500 Ω, and major part wherein, preferred more than 70% and preferably especially share by Ohmage more than 90%.
Each member of described circuit as printed conductor (Leiterbahn), coil, capacitor and Ohmage, is preferably made by printing technology, that is is stamped on the substrate.For example can be following the manufacturing printing Ohmage and determine its size:
(a) by the carbon/graphite-based pigment of conduction, wherein, the live width by the Ohmage printed conductor, line density, bed thickness or length are implemented the adjustment of expectation resistance,
(b) polymkeric substance by conducting electricity, for example PEDOT (Baytron of H.C.Starck
Or the ORCACON of AGFA
), wherein, the live width by the Ohmage printed conductor, line density or bed thickness are implemented the adjustment of expectation resistance,
(c) by also constituting the identical low ohm material of described other parts of circuit, for example silver is made tiny printed conductor,
(d) or under (a) and situation (b), replace the structure of forming gapping element by the printed conductor section, use the structure of forming by the element of planar printing.Implement the adjustment of expectation resistance this moment by the bed thickness of impression.
As the replacement that is applied directly to by printing technology on the substrate, can be the film paster (Folienapplikation) of safety label (Sicherheitsetikett), so-called paster (Patch) or safe band (Sicherheitsstreifen) form also, and then be transplanted on the substrate circuit design.
Each Ohmage is preferably in parallel.Particularly preferably pass through the Ohmage of the additional parallel connection of Ohmage of other series connection, thereby the resistance of thereby different capacity grade also big or small by these preferred differences can at first be realized the response sensitivity of relative broad range and make it visual.At this, get when appropriate in size design, can reach the also colour switching of resolving time of not only differentiating the position.Thus, for example when the series connection Ohmage that resistance value is reduced from the Ohmage to the Ohmage gradually is " ladder-type " and arranges, what obtain the thermochromism chromatograph a kind ofly follows the Ohmage colour switching of " moving about ".At first first Ohmage heating, next then, by that analogy.
The triggering speed of heating element depend on its area or thermal capacitance and Ohmage with and trigger the poor of temperature and environment temperature.Therefore slow for the less element of the ratio of transformation of bigger its color of element; When area is identical,, then there is the element of big Ohmage to compare triggering more promptly with the element that less Ohmage is arranged if these elements are connected.Situation is opposite when parallel connection.Therefore by design rightly, can cause a kind of movement effects.
Except on how much, the distinct color conversion, under the situation of appropriate layer structure, also can distinguishing of having illustrated by temperature or heating by excitation and time sequencing.At this, for example on circuit, print two chromatographs that the thermochromism of identical or different pattern is arranged stackedly, what wherein be in the bottom for example have+50 ℃ transition temperature, and be in the transition temperature of for example the having of top+25 ℃.Therefore, when the supposition of the chromatograph of the thermochromism that is in the bottom from green to the blue and chromatograph supposition of thermochromism that is in top from black during to colourless turn colors, under situation, obtain by the finger thermal excitation a kind of from black to green colour switching, and when the electric excitation that adds than macro-energy, then cause colour switching from black to indigo plant.When the blend of colors of thermochromism, also can reach color conversion continuous on time/temperature in this way.
If replace aforementioned from black to colourless conversion, and on a simple black background, adopt a kind of color that the liquid crystal pigment of thermochromism is arranged, present colour according at that time temperature so.Therefore by changing area and resistance and it on purpose being arranged, can produce the image/pattern that changes color in time.Other designs of this respect are provided in DE 10 2,006 016 048, have adopted its relevant therewith disclosure at this.
If use when in room temperature or environment temperature, being in basic status color as the thermochromism of black as superposed visible layer, then advantageously add the effect look of a polarization of chromatography, illustrating among DE 10243650A1 or the WO 2004028824A2, adopted its relevant therewith disclosure as it here.Differentiate black surface aesthetically on the one hand thus, polarization of reflected lightization is a kind of additional measures on the other hand.
Under appropriate structurized situation, also can after printing, carry out independent processing or change again to image, symbol, pattern etc.Thus can be with by feature of the present invention and another single sign, for example numeral combines.As an example, write a numeral, on it, apply a thermochromic layer all sidedly with the form of 7 common segment pointers.When basic status, all sections contacting also is connected with circuit, so present numeral 8 when the input electric energy.Disconnect indivedual sections by selectivity now, also can explain all other numerals of from 0 to 9.This for example can be the check number by traditional reference numbers of book and periodical printing method or toppan printing or ink jet printing method or laser instrument.The disconnection of each segmentation advantageously by laser instrument, realizes by the otch that ablation (Ablation) on the node of the 7 segment pointer printed conductors that relate to is little.
When the RFID label also was applied on the independent packing of retail trade more and more in the near future, the present invention produced outstanding advantage.Thus, as now bar code scanning machine or be used to discern the UV-lamp of banknote authenticity, corresponding RFID reading machine will be general at checkout terminal equally.Can realize a kind of new Inspection Method that has by the authenticity of the value document of security element of the present invention that is used to differentiate now by described RFID reading machine.When the RFID in future reading machine also is integrated in the mobile phone, this feature will win additional attractive force.
For machine readable,, and follow the change color of assessing the thermochromism of every banknote by machine by all banknotes of (Anlagestapel) in radio frequency radiation excitation wad or the equipment wad of bills by security element of the present invention.
