    description
    SAFETY THERMAL CARRIER
    The subject of the utility model application relates to a Sicherheitssthermodruck-carrier with a base layer, arranged on this base layer release layer and a heat-sensitive layer or thermo-layer, which is attached to the release layer.
    In all areas of the economy, including transport, direct thermal printers are most suitable for individual presentation of information content that can be used in such operated in counters as by passengers ticket machines. The basis for protection against counterfeiting of the tickets thus created is the protection of the paper material used as a basis for the tickets. Counterfeiters obtain the base paper that is used most for counterfeit purposes, such that they chemically acquire the original content from an already depreciated or low value unused ticket, and then impart the wrong content to the surface by a different method (laser printing) of the base paper. The counterfeits produced with such a method are of very good quality and can usually only be explored by means of a targeted examination with the use of instruments. The economic damage caused to the service providers can be significant, so the ticket paper manufacturers have developed various protective measures. In previous security solutions, chemical protection in the heat-sensitive layer or in the base layer, e.g. B. formed in the base paper. There are such fluffy fibers that fluoresce in different colors when illuminated with UV light, or so-called "planchets", which are usually paper discs with a diameter of 2 to 3 mm containing any reagent for chemical protection. The color content of the substances used for the purpose of chemical protection can be removed without residue by means of prolonged and abundant soaking from the paper material. A protection of this kind serves exclusively the defense against partial change of the data contents. W001 / 05603 provides protection against counterfeiting of a data carrier, e.g. As a ticket is a method in the course of which a control mark on the paper is visible as a result of a further external influence. The control mark contains at least one thermal opaque coating comprising a polymer matrix composition containing melamine formaldehydes and acrylic resins, a coldset ink type thermosensitive substance containing 1-hexa-decanol and 4-ethylphenol, butanol, amine resin and ethyl acetate. The external effect can be a thermal action or UV irradiation, for. B. be a thermal print. It is disadvantageous in this solution, that although the originality of the base paper confirmed, but no protection against the chemical invisible of the elements produced in the thermal coating by thermal printing and against the subsequent generation of a superficial color printing is offered.
    It is therefore intended with this utility model to produce a Sicherheitsthermodruck-carrier, which is capable of eliminating the disadvantages of belonging to the prior art solutions, d. H. a falsification of the data content of the print carrier should be clearly perceptible to the naked eye, whereby invisibilization of the elements produced in the thermal layer by means of thermal printing by chemical means and a subsequent discharge of a superficial color print becomes pointless.
    The object has been achieved by the production of a security thermo-print carrier comprising a base layer, a release layer disposed on this base layer, and a heat-sensitive layer or thermal layer attached to the release layer, wherein a security color layer is applied along an opposite surface of the thermal layer to the release layer is that contains iridescent pigment plates.
    Between the thermal layer and the iridescent pigment plates containing security color layer a protective layer is suitably arranged, which is connected to the security color layer by means of permanent chemical bond.
    The thickness of the pigment plates is at most 3 pm.
    The thickness of the security color layer containing the pigment plates is at most 5 pm.
    At the opposite surface of the release layer of the base layer, a protective layer is attached.
    The subject of the utility model application is shown below with reference to an expedient embodiment with reference to the accompanying drawings. FIG. 1 shows a section of an embodiment of a security thermoprinting support according to the utility model in cross-section, and [0011] FIG. 2 shows the position of a thermal printing subsequently carried out on the
    Security thermal print carrier imprinted.
    Figure 1 shows the structure of an embodiment of a Sicherheitsthermodruckträgers according to the utility model in cross section. A base layer 1 of the print carrier consists in the illustrated embodiment of a paper layer, but the base layer 1 can also be made of other materials, eg. B. made of plastic. On the base layer 1 is provided a release layer 2 comprising the base layer 1 and a heat-sensitive layer, i. Thermo layer 3 of the print carrier separates from each other, at the same time connects to each other. In FIG. 1, a discoloration 6 has been drawn in the thermal layer 3, which forms a part of the data content arising in the thermo layer 3 of the print carrier after the thermal modifier. In the preferred embodiment shown in FIG. 1, there is a protective layer 4 on the thermal layer 3, which protects the latter against environmental influences. The protective layer 4 can be suitably used in such applications where the resistance and the protection of the thermal layer 3 of the print substrate against environmental influences to be strengthened. The security thermal print carrier according to the utility model can therefore also be produced without the use of the protective layer 4. A similar situation also exists in a protective layer 5 used in the embodiment shown in the figure.
    It is clearly visible in Figure 1 that on the surface of the protective layer 4 facing the thermal layer 3 is applied a security ink layer 7 which is heat-resistant and iridescent, i. E. suitable for color change, allophanie, color scintillators and from a after printing the printing of their color changing printing ink " FLEXO " (persoprotect flexo ink) is made. As already mentioned, in such a case where the protective layer 4 is omitted, the security color layer 7 can be applied directly to the thermo layer 3, but the security color layer 7 is in all circumstances disposed on that surface of the thermo layer 3 facing the release layer 2 is and is preferably applied by means of a printing process on the print carrier.
    The security color layer 7 generates on the surface of the protective layer 4 by oxidative polymerization, or due to cohesive forces a strong and insoluble bond. The security ink layer 7 is made from acrinate-based heat-resistant coating containing a 25% aqueous acrylate emulsion mixture, foam inhibiting additives, flowability adjusters, pH adjusters, bactericides, fungicides, isopropyl alcohol in an appropriate ratio of 5.5% total, water 68.5-64.5%, further iridescent metallized pigment plates z. B. on rutile basis of 1-5%, the structure reflect incident light in different colors. This mixture can be prepared with a paddle stirrer at a stirring speed of 500 rpm in 20 minutes. While the white, z. For example, if the base layer 1 securing the paper backing reflects all colors and these add up to the colors of wavelengths reflected by the pigment plates, the background color will be modified due to discoloration that occurs during the thermal printing process under the security color layer 7 in the thermal layer 3. This resulting black discoloration 6 swallows the incoming colors so that only the colors reflected by the pigment plates become visible. A common feature of the iridescent pigment plates is a different metallic and pearlescent gloss and a mixture of mica schist and titanium dioxide produced in special processing. The thickness of the plates of the pigment pills having a plate structure in the security color layer 7 is at most 3 pm, their other maximum dimensions may also reach 200 pm. It is therefore advisable to apply the security color layer 7 in a thickness of 3 to 5 pm to the protective layer 4. Since acrylates have poor thermal conductivity, a layer thickness of more than the aforementioned 5 pm is not advisable. Unfortunately, the poor thermal conductivity is not even improved by the iridescent pigment plates mixed in the paint. The applied security ink layer 7 forms a closed, water- and solvent-resistant ink layer 7. It is not appropriate to apply the ink layer 7 on the entire surface of the print carrier, because the iridescent effect comes into its own when the ink layer 7 creates a drawing.
    The ink layer 7 can be suitably applied in an area to be provided with data content of the print carrier to be protected, since any data content can be read out under the protective layer 4. The color layer 7 has been identified as a security print because of its highly visible discoloring effect, and the data content printed by a thermal printer is easy to read. The color layer 7 located above the black thermal ink 6 formed as a result of the thermal printing (eg printing of ticket data on the print substrate) under the ink layer 7 reflects purple or green colors instead of the original gray-green color from the incident light. By removing the discoloration (i.e., imprint) produced by the thermal printer from the thermal layer 3, which also makes the thermal layer 3 unprintable, it can subsequently be printed only on the surface of the color-changing ink layer 7 with a printing method different from the thermal printing, e.g. As laser printing, but not under the layer, as it is the figure 2 can be removed printed. Since the subsequently applied printed image is applied to the previously printed ink layer 7, the color play of the color layer 7 shown above is omitted and the color-changing security ink layer 7 is clearly concealed by the subsequently imprinted impression. The difference is clear and provides reliable protection against the counterfeiting method mentioned above.
    It is also advantageous if in the color layer 7 such a security element is embedded, which serves to protect the authenticity of transport tickets. It is useful if this element neither with the naked eye nor with simpler means, for. As a magnifying glass, UV lamp, etc. can be perceived. It is also advantageous if this security element is also suitable for automatic testing within the ticket vending machine. This security element can, for. Example, be an active in the infrared region material that emits in response to excitation radiation, an infrared radiation having a characteristic spectral distribution in the range of 800 to 1200 nm. This emission can be detected with a hand-held detector developed for this purpose. The detector gives clear sound and light signals by detecting the presence of the material or security element.
    Since this infrared radiation means intense emission and on the spectral level is clearly separated from the emissions of the material of the ticket and their prints, is particularly well suited for automated controls.
    The emitting in the infrared range ink layer 7, which contains pigments of appropriately activated with erbium or ytterbium activated rare earth metals and iridescent, metallized pigment plates rutile-based, is therefore also for the protection of completing the ticket and the authenticity of the ticket suitable.
    The Sicherheitssthermodruckträger according to the utility model is in contrast to the prior art solutions suitable to make the falsification of his data content clearly and with the naked eye, whereby the chemical elimination of the formed by means of thermal printing in a thermocouple elements and a subsequent Production of a surface print 10 is futile.
