Description
The present invention relates to a kind of safety element, it comprises the chromatograph of at least one thermochromism.A first information covers by the chromatograph of this thermochromism, thus this first information can not be recognized.Time only in heat to add thermochromism chromatograph by first kind of way, just can see the described first information.
By the known safety element by type of the present invention of EP 1,320 836 A2, wherein, within value document and secure file or on the electronic chip being at least LCR oscillation circuit form is set.At this, LCR oscillation circuit by an inductance be the coil of L, electric capacity is the electric oscillation loop that the capacitor of C and an Ohmage R form.Electromagnetic radiation source, such as RFID (radio-frequency (RF) identification) reading machine or simple transmitter, the LCR oscillation circuit described in excitation, at this, produces heat by special loss power, and directly or by the reaction of special indicant knows.Described special indicant reaction is such as realized by the colour switching of the chromatograph of the thermochromism on value document and security file internal and/or surface.
But this safety element is not suitable as machine-readable mark.The colour switching of the chromatograph of thermochromism is carried out so slow, so that it can not reach in the bank note processing machine of 40 banknotes p.s. in current conventional processing speed and uses.
More serious shortcoming is, cannot distinguish is cause heating or color conversion owing to absorbing by the electromagnetic radiation of RFID reader antenna, or the heating undertaken by other approach.The heating of other approach can be such as the heat transfer by hand, the radiation of absorption modulation, or the environment temperature raised.If even if be such as+45 DEG C due to such as color conversion temperature and the environment temperature being imported into heat and rising by hand can be foreclosed, but owing to such as passing through safety element capacity effect that is contaminated and that the mode that safety element " is held in the hand (In-der-Hand-Haltens) " caused, and the electricresistance effect to be caused by fold (Verknitterung), and can not determine LCR oscillation circuit resonance frequency accurately, and thus can not determine its energy absorbed.Therefore heating and associated authenticity prove insecure.
Therefore technical matters to be solved by this invention is, so further improvement is by the safety element of described type, so that the shortcoming overcoming prior art also improves anti-counterfeiting performance further.
This technical matters is solved 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 second information except the covering first information.This second information also can not be recognized in certain temperature range, such as, under common environment temperature or when room temperature.Only when heat adds in the chromatograph of thermochromism by preferred the second type of heating different from the first type of heating, just can see described second information.
Therefore by the present invention, when by first kind of way heating, color conversion distributes with the geometry different from when heating by the second way or different geometric schemes carries out.
Therefore, when by first kind of way heating, only have the certain area of the chromatograph inside of thermochromism to change, wherein, described region is particularly preferably designed to the geometric configuration of pattern, alphanumeric symbol or image.The profile of described certain area forms the described first information.
Such as, otherwise when by second way heating, time by finger or lamp heating, the surface of the chromatograph of whole thermochromism of being heated changes.At this, the second information or the appearance profile by the surface of turn colors are formed, or additionally being formed by the dimensional printed chart below the chromatograph that is in thermochromism from coloured to during the color conversion of colourless or transparent thermochromism.Described dimensional printed chart is the form of pattern, alphanumeric symbol or image in the finger of heating or the indoor design of light cone profile, such as, be designed to symbol
structure.
Described first and second information preferably have the different information contents, and wherein the first and second information can directly be arranged on the stacked or ground that offsets each other.Therefore such as the first information can embody word or numeral, and the second information presents the coloured surface of cartouche shape.The information contents different within the scope of the invention also comprises, although the first and second information state identical word, identical numeral, identical pattern etc., element has different sizes or different colors or rotates each other or arrange with being staggered separately.
Alternatively, the first and second information also can have the identical information content.The first and second information but must by positions different on safety element for the first and second information placement, or only allow to partly overlap in this case, because otherwise will have the identical information content.Such as the first and second information show that size is identical, the identical numeral identical with color " 50 " of font respectively, but they rotate each other more or less or arrange with being staggered, thus make them incomplete same or directly not arrange stackedly.
Except the first and second information, the chromatograph of described thermochromism additionally can cover at least another information, and it can not be recognized equally.Just can see when another information described is only in the chromatograph that heat adds thermochromism alternatively, described another kind of type of heating is different with the second type of heating from the first.The advantage obtaining thus giving prominence to is, " can hide " three or more information in described safety element, itself or in different location, there is the identical information content, or there is the different information contents, improve anti-counterfeiting performance further thus.
The present invention not only relates to the substrate with safety element, and relates to and have the data carrier that comprises the substrate of safety element.At this, data carrier is value document especially, such as banknote, security, credit card or certificate, passport, proof document and so on, label, packaging or other element for product safety.
By a kind of optional form of implementation, at least one information is located at the side of substrate, and the chromatograph of at least one thermochromism is located on the opposite side of substrate.In this case, heat through substrate or safety element.The advantage done like this is, the relation between the chromatograph of the information on potential fake producer's None-identified substrate side and the thermochromism on substrate opposite side, thus improves anti-counterfeiting performance further.If the chromatograph of especially information and thermochromism is all integrated in the design of safety element or data carrier or in another safety element, can further improve anti-counterfeiting performance.
Especially, described safety element has at least one circuit, and at this, described circuit has the Ohmage that at least one 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 inputting electric energy in circuit, being arranged in above Ohmage or being close to the area transformation color of Ohmage of the chromatograph of only thermochromism.Realize thus at least can seeing the partial pattern of Ohmage, alphanumeric symbol or image in the chromatograph inside of thermochromism.
Therefore Ohmage bears the task of heating element.They are arranged by matrix structure or with any contour shape, such as, be the shape of numeral " 50 ", and cover also thus hidden with the chromatograph of thermochromism.When electric excitation, the chromatograph of thermochromism heats by Ohmage, thus presents another kind of color in the chromatograph inside of thermochromism or become transparent numeral " 50 ", and it is consistent with the numeral " 50 " formed by Ohmage in its shape with area.
When circuit design is the circuit of non-closed, described electric excitation realizes by contacting with the Direct Current of power supply.Such as described galvanic contact is realized by the contact between battery and circuit.
For the closed circuit being oscillation circuit or LCR oscillation circuit in form, electric excitation is preferably realized by electromagnetic radiation coupling and the magnetic induction coupling particularly preferably passed through in radio-frequency band (RF) internal field non-contiguously.The resonance frequency of LCR oscillation circuit or the frequency of operation of respective transmit antenna are preferably in 1MHz to 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 is preferably within the scope of 100 Ω to 1K Ω, and particularly preferably in the scope of 150 Ω to 500 Ω, wherein major part, preferably more than 70% and particularly preferably more than 90% is shared by Ohmage.
Each component of described circuit, as printed conductor (Leiterbahn), coil, capacitor and Ohmage, makes preferably by printing technology, that is is stamped on substrate.Such as can manufacture the Ohmage of printing as follows and determine its size:
A (), by carbon/graphite-based pigment of conduction, wherein, implements by the live width of Ohmage printed conductor, line density, thickness or length the adjustment expecting resistance,
(b) by conduction polymkeric substance, such as PEDOT (H.C.Starck's
or AGFA
), wherein, implement by the live width of Ohmage printed conductor, line density or thickness the adjustment expecting resistance,
C (), by also forming the identical low ohm material of described other parts of circuit, such as silver, manufactures tiny printed conductor,
(d) or when (a) and (b), replace the structure being made up of gapping element printed conductor section, the structure formed with the element printed by planar.Now implement by the thickness of impression the adjustment expecting resistance.
As the replacement be applied directly to by printing technology on substrate, also can be the film patch (Folienapplikation) of safety label (Sicherheitsetikett), so-called paster (Patch) or safe band (Sicherheitsstreifen) form by circuit design, and then be transplanted on substrate.
Each Ohmage is preferably in parallel.Particularly preferably supplement Ohmage in parallel by the Ohmage of other series connection, thus the resistance of by these preferred different sizes and thus different capacity grade, first can realize the response sensitivity of relative broad range and make it visual.At this, when size design obtains appropriate, the colour switching of not only differentiating position also resolving time can be reached.Thus, such as, when series connection Ohmage resistance value reduced gradually from Ohmage to Ohmage is arranged in " ladder-type ", the one obtaining thermochromism chromatograph follows Ohmage " travelling " colour switching.First the first Ohmage heating, then next, by that analogy.
The triggering speed of heating element depends on the difference of its area or thermal capacitance and Ohmage and its trigger temperatures and environment temperature.Therefore slow for the element that the conversion of larger its color of element is smaller; When area is identical, if these elements are series connection, then more promptly trigger compared with having the element of larger Ohmage and having the element of less Ohmage.When parallel connection, situation is contrary.Therefore by designing rightly, a kind of movement effects can be caused.
Except illustrated by excitation and time sequencing except the conversion of geometrically distinct color, also can distinguish by temperature or heating when appropriate Rotating fields.At this, such as, on circuit, print the chromatograph that two have the thermochromism of identical or different pattern stackedly, be wherein in the transition temperature such as with+50 DEG C of bottom, and be in the transition temperature such as with+25 DEG C on top.Therefore, when be in bottom thermochromism chromatograph supposition from green to the chromatograph supposition of thermochromism that is blue and that be in top from black to colourless during turn colors, when by pointing thermal excitation, obtaining a kind of colour switching from black to green, and then causing the colour switching from black to indigo plant when adding the electric excitation compared with macro-energy.When the blend of colors of thermochromism, continuous print color conversion on time/temp also can be reached in this way.
If replace aforementioned from black to colourless conversion, and adopt a kind of color having the liquid crystal pigment of thermochromism in a simple black background, so present colour according to temperature at that time.Therefore by changing area and resistance and it on purpose being arranged, the image/pattern changing color in time can be produced.In DE 102006016048, provide other designs of this respect, adopt its disclosure related to this at this.
Be that the color of the thermochromism of black is as superposed visible layer if be used in room temperature or environment temperature when being in basic status, the then effect look of an advantageously additional chromatography polarization, as it illustrates in DE 10243650A1 or WO 2004028824A2, adopt the disclosure that it is related to this here.Differentiate black surface aesthetically on the one hand thus, the polarization of reflected light is a kind of additional safety measures on the other hand.
In appropriate structurized situation, also can carry out independent process or change again to image, symbol, pattern etc. after printing.Thus can by by feature of the present invention and another single mark, such as numeral combines.As an example, write a numeral with the form of 7 common segment pointers, on it, apply a thermochromic layer all sidedly.When basic status, all sections of contactings are also connected with circuit, so present numeral 8 when inputting electric energy.Disconnect indivedual section by selectivity now, also can state other numerals all from 0 to 9.This can be such as the check number of the traditional reference numbers by 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, the otch little by ablation (Ablation) on the node of the 7 segment pointer printed conductors related to realizes.
When RFID label tag in the near future be also applied to more and more retail trade pack upper separately time, the present invention produces outstanding advantage.Thus, as bar code scanning machine now or for identify banknote authenticity UV-lamp, corresponding RFID reading machine will be same general at checkout terminal.A kind of new Inspection Method of the authenticity for differentiating the value document had by safety element of the present invention can be realized now by described RFID reading machine.When future RFID reading machine also integrated in the mobile phone time, this feature will win additional attractive force.
