Definitions

  • the present invention relates to a security element particularly for banknotes, security cards and the like, which has a high anti-counterfeiting capability.
  • a thread is also known, for example, in which, in order to increase the security characteristics, at least one full-surface layer is added which therefore covers both the regions without metal and the metallic regions with ink which has fluorescent properties.
  • Patent applications WO2004/014665 and WO2004/098900 relate to so-called partially demetallized threads.
  • EP 516 790 discloses a thread in which detectable magnetic regions are inserted between the letters formed by performing a total demetallization, so that the thread can therefore be detected both as conductive (due to the presence of metal deposited in continuous form) and by means of magnetic sensors (by virtue of the magnetic elements arranged above or below the layer of metal, but never inside the letters).
  • EP 516 790 discloses a security device in which the characters or letters are completely demetallized.
  • a rotary press with a plurality of printing sections as described above also in EP 516 790 , printing on a transparent material (generally polyester) printed elements with removable inks, performing vacuum metalization on the full surface so as to cover the removable inks, removing the inks and consequently also the metal that covers them, then leaving printed elements which are identical to the ones printed with removable inks, and then printing with magnetic inks continuous or discontinuous areas in the regions which have not been demetallized and are therefore adjacent to the demetallized regions.
  • the presence of magnetic elements is not visible with ordinary viewing instruments (naked eye, optical magnifiers, et cetera), since they are always covered by metal.
  • the magnetic elements are visible exclusively with suitable devices dedicated to detection of magnetism.
  • GB 2 319 215 discloses a security thread with magnetic patches and visually-readable characters in parallel.
  • US 6 343 745 discloses a security element for a security document such as a bank note, ID card or the like consisting of a translucent plastic layer having an opaque layer with gaps in the form of characters, patterns or the like recognizable in transmitted light.
  • US 5 614 824 discloses a harmonic-based verifier device for a magnetic security thread having linear and non-linear ferromagnetic characteristics.
  • US 5 516 153 discloses a security element for use in a security document such as a bank note, identity card or the like that includes at least a partial metallic coating on a substrate and wherein the metallic coating includes recesses in the forms of characters or patterns that are visually recognizable at least in transmitted light and a magnetic coating of soft-magnetic pigments disposed in overlying relationship with the metallic coating
  • US 5 631 039 discloses a method of manufacture of a security thread suitable for use in security articles including security paper such as that used for banknotes.
  • the aim of the present invention is to provide a security element, particularly for banknotes, security cards and the like, which has magnetic elements at least in the regions without metal, said magnetic elements being visible by means of a normal magnifying lens.
  • an object of the present invention is to provide a security element, particularly for banknotes, security cards and the like, in which said magnetic elements are visible in the regions without metal at least in transmitted light, by using a normal magnifying lens.
  • Another object of the present invention is to provide a security element in which the magnetic elements can be detected even by devices for detecting magnetic properties.
  • Still another object of the present invention is to provide a security element for which counterfeiting is even more difficult than for known types of security elements.
  • a security element particularly for banknotes, security cards and the like, as defined in claim 1.
  • the security element according to the present invention is as follows.
  • security element is used to reference a security thread, stripe or patch, to be applied or inserted at least partially in paper for banknotes or security documents, such as passports, or in plastics such as PVC, PET, et cetera, for credit cards.
  • the security element according to the invention is generally designated by the reference numeral 1.
  • identical reference numerals designate identical elements.
  • a substrate made of plastics, such as polyester, which is not shown explicitly in the figures, since such figures show the security thread in plan view; at least one opaque layer, conveniently for example a layer of metal such as aluminum, nickel, silver, et cetera, is deposited on such substrate, for example by vacuum deposition on the full surface.
  • a so-called "resist" ink based on nitrocellulose is printed on this layer of metal, which is designated by the reference numeral 2, and allows to preserve the metal deposited in vacuum against subsequent etching, performed for example with acid, for example 52% phosphoric acid at 50°C for a speed of 40 m/min with an immersion path which is 23 m long, or with 0.8-1% soda with a temperature and a speed which are similar to the acid.
  • Etching with acid allows to remove the metal in the areas in which the resist INK is not printed.
  • the resist is not printed normally in the areas that correspond to characters or markings 3 defined on the security element.
  • the metal layer 2 can be removed completely from the areas in which the characters 3 are defined, so as to have the inside of the characters fully transparent, or can be removed only partially, obtaining therefore a reduction in the thickness of the layer of metal 2, as shown for example in Figures 6 to 10 .
  • the printed elements i.e., characters, lettering and the like, can be either negative or positive.
  • the metal can be deposited in vacuum by means of vaporization machines or can be transferred either hot or cold, or, skipping the metalization and demetallization steps, printed with inks and pigments which are metallic or have a metallic effect.
  • the peculiarity of the invention consists in that it provides, on a security element provided as described above, according to the background art, for the presence of at least one magnetic element which is arranged at least within the printed elements which are totally or partially without metal.
  • Figures 1 to 5 illustrate a situation in which the characters, designated by the reference numeral 3, are fully demetallized, and magnetic elements, designated by the reference numerals 4 and 6, are provided inside them, while Figures 6 to 10 illustrate the situation in which the characters are demetallized only partially and are obtained by reducing the thickness of the metal, and are designated in this case by the reference numeral 8.
  • Figures 1 to 5 are repeated mirror-symmetrically in the embodiments of Figures 6 to 10 , with the only difference that in the first five figures the characters that are present on the security thread are totally demetallized, whereas in the second five figures the characters are demetallized only partially.
  • Figures 1 to 5 apply also to embodiments in which the characters are obtained from negative prints of metallic or metallic-effect inks.
  • the resist ink described above with resins which are sensitive to bases, i.e. resins which protect the metal against acid etchings such as phosphoric acid, which can then be removed for example by means of a bath in sodium carbonate with 1% dilution (pH 12) at 50°C at a rate of 40 m/min with a path of immersion of the security element of approximately 23 meters.
  • resins which are sensitive to bases i.e. resins which protect the metal against acid etchings such as phosphoric acid, which can then be removed for example by means of a bath in sodium carbonate with 1% dilution (pH 12) at 50°C at a rate of 40 m/min with a path of immersion of the security element of approximately 23 meters.
  • inks described above it is possible to provide a security element or thread by using therefore, as mentioned above, a backing made of plastics, such as polyester for example, on which, by vacuum deposition, the layer of metal such as aluminum, nickel, silver, et cetera is then deposited on the full surface.
  • a backing made of plastics such as polyester for example, on which, by vacuum deposition, the layer of metal such as aluminum, nickel, silver, et cetera is then deposited on the full surface.
  • a protective resist is then printed onto the layer of material thus provided, as described earlier, and allows to protect the metal against acid etchings and to leave free the unprotected regions, so that the metal can be removed totally or partially in order to provide characters which are totally or partially demetallized.
  • magnetic inks provided for example with suitably treated iron oxides, as regards both particle size distribution, which must be the finest possible (generally a magnetic ink contains particles with a size of around 4-5 ⁇ m, while in the present invention it is useful for said size to be for example less than 2 ⁇ m), and for the resin, which must have a great capacity to grip the polyester and the metal and/or the resist which is printed to define the printed elements.
  • the magnetic dots which can also be bands, lines or the like, designated by the reference numerals 4 and 6, as described earlier, can be provided both within the regions that define the characters and outside them, as described in detail hereinafter.
  • the security element can thus be finished by coupling it to another layer of polyester and with the addition of a hot-melt external adhesive for anchoring to the fibers of the paper within which the security element will have to be positioned.
  • a second method which can be used to provide the security element according to the invention entails printing the magnetic dots or in any case the magnetic elements both on the resist with nitrocellulose resin, used in the demetallization step, and inside the printed elements with partial or total absence of metal.
  • inks which contain iron oxide particles for example wrapped by resins which protect the oxide and at the same time do not allow a corrosive action thereof on the metal onto which these inks must be deposited, and at the same time allow optimum anchoring in the regions where the metal is not present.
  • the method used in the invention provides, as a solution, spreading onto the polyester substrate, before metalization, a primer which is based only on nitrocellulose in infinitesimal amounts, so that once the metal has been removed in the demetallization process, the regions that remain without metal have an optimum predisposition for anchoring with the magnetic ink which is deposited subsequently.
  • the magnetic elements or magnetic areas that are printed in the regions which lack metal completely or partially can have any shape, such as for example a thin line, or a series of thin lines, or a series of dots, all these elements with mutually identical or different widths and spacings.
  • a further process for providing the invention entails providing a film made of plastics such as polyester onto which a layer of aluminum is applied on the full surface by vaporisation in vacuum, and printing thereon the resist with the printed elements in which the metal is to be removed totally or partially by chemical removal as mentioned earlier.
  • a plastic film which has printed elements which are legible in transmitted light and inside which there may be a complete absence of metal or there may be such an amount as to allow in any case its legibility in transmitted light.
  • the metal inside the printed elements can have remained there by partial reduction of the original thickness or by total removal in a first chemical pass to then return to deposit a minimal amount thereof with a second pass in a metalization machine.
  • a second film is prepared starting again from a backing made of plastics such as polyester, on which metallic or metallic-effect inks can be printed for preparation to receive magnetic inks; in this case, instead of the metallic inks it is possible to use previously demetallized regions.
  • the dots with magnetic ink are printed and, if necessary, so are other magnetic regions as well, which can form various types of codes, as explained in greater detail hereinafter. Both the dots and the magnetic regions must be printed so that with a further pass it is possible to couple the two films, one of which is metalized and demetallized and the other one is printed with magnetic inks on metallic inks and/or on metal.
  • the aim of the invention is to obtain areas with magnetic properties which are suitable both to be detected simply with a magnifying lens and to be detected by dedicated devices with manual, semiautomatic and automatic transport.
  • the amount of magnetic oxide introduced in the magnetic ink must be such as to have, for example, at least a residual magnetism of 100 nWm and a coercivity of more than 100 oe.
  • the areas with magnetic properties described above, which are present at least in the regions without metal, i.e., at the regions of the characters, or at the regions of the characters and outside them, may be provided with a plurality of types of magnetic inks, i.e., inks with different coercivities and identical residual magnetism, or with different coercivities and a different residual magnetism, or with identical coercivities and different residual magnetism, or with identical coercivities and identical residual magnetism, which can be printed or deposited alternately or side-by-side between the regions without metal and the regions with metal, and be printed or deposited alternately or side-by-side over each other.
  • the different coercivity of the inks can be achieved both by means of different oxides and by means of mixtures among them.
  • the different residual magnetism can be obtained by varying the percentage of different oxide within the ink and by using identical areas, identical inks but different thicknesses.
  • the magnetic areas described above can be provided so as to obtain magnetic elements in the regions without metal, with different magnetic and colorimetric intensity depending on whether the dots are in the regions without metal or in the adjacent regions, i.e., regions below or above the metal.
  • the different magnetic intensity can be noticed by observing the magnetic dots superimposed on the demarcation line between the regions with metal and the regions without metal.
  • the magnetic dots are printed over the nitrocellulose-based resist, which is used to preserve the metal from the regions in which the metal must be removed.
  • the ink used to print the dots can be provided conveniently for example by means of nitrocellulose resins in an amount of approximately 50% of the dry product, the remaining 50% being necessarily composed of magnetic material.
  • An ink of the type described above allows, during treatment in acid, to be etched chemically more where the areas are extremely small (for example dots) and arranged directly on metal and not on the resist, thus creating the conditions for a decrease in quantity and therefore greater transparency and a different magnetic signal.
  • the magnetic elements can be provided so as to obtain a reduction in the area of the dots arranged in the regions without metal, so that with a normal magnifying lens it is possible to notice the difference in area between the dots located in the regions without metal and the dots located in the regions with metal, i.e., adjacent to the characters.
  • the magnetic elements 4 are provided exclusively within the areas of the characters 3 which are fully demetallized.
  • the second embodiment shown in Figure 2 , provides for the deposition of magnetic elements also in the regions where the metal is present, i.e., the regions adjacent to the characters 3, which in this case also are completely demetallized.
  • Such additional magnetic elements arranged above or below said at least one metalized layer, are arranged on the two edges of the security element continuously or alternately.
  • Figure 3 is a view of the third embodiment, in which the magnetic elements, designated by the reference numeral 5, have a smaller area than the magnetic elements 4 arranged outside the characters.
  • the characters 3 are fully demetallized and the magnetic elements 5 contained therein have a smaller area than the magnetic elements 4 that lie outside the characters and therefore on the metalized surface.
  • the magnetic elements designated by the reference numeral 6 have a different thickness with respect to the magnetic elements 4 that are provided outside the characters. Therefore, in the fourth embodiment the magnetic elements 6 that are present within the characters, which are fully demetallized, have a different thickness with respect to the magnetic elements 4 that are present in the regions adjacent to the characters, i.e., above the metal layer.
  • the fifth embodiment has as a difference the presence of magnetic regions outside the areas that define the characters, where such regions are designated by the reference numeral 7, and are therefore arranged above the metalization layer 2.
  • Figures 6 to 10 are absolutely similar to Figures 1 to 5 , with the difference that the characters, now designated by the reference numeral 8, are demetallized only partially, and therefore the embodiments of Figures 1 to 5 correspond respectively to Figures 6 to 10 , except indeed for the fact that the characters are partially and not totally demetallized.
  • the presence of the magnetic elements defined above can be combined with other characteristics of security elements, such as for example holography, which can be provided on the metallic or nonmetallic regions or on both or by using polyester films on which, by means of vaporization systems, materials are deposited such as chromium, magnesium fluoride, silicon or aluminum oxide, used commonly to provide films with color-shifting characteristics depending on the angle of incidence with which they are struck by the light and viewed.
  • security elements such as for example holography
  • the change of color of the metallic layer can be determined by two different metals such as aluminum, copper, or again copper, gold, et cetera. Going back to the concept of color variation, reference is made to the so-called "color shift" effect, which is obtained by depositing in vacuum materials such as magnesium fluorides, chromium, aluminum oxides, silicon, et cetera, the color result of which changes depending on the inclination with which they are struck by the light and by the angle of reflection. Two of the most widely used colors are magenta, when viewing the film by aligning it axially with the viewpoint of the observer, becoming green when the film is inclined at 60°.
  • fluorescent inks which can be provided in the metallic regions and in the regions without metal or also on both.
  • the security element according to the invention fully achieves the intended aim and objects, since it allows to have magnetic regions at the characters which are totally or partially metalized and also optionally outside said characters, which therefore constitute an additional element of difficulty for any counterfeiting of the security element.
  • the magnetic elements thus defined have the advantage of being detectable directly by means of a simple magnifying lens, thus facilitating verification of the authenticity of the documents in which the security element according to the invention is inserted even by non-expert people.
  • the difference in coercivity should be for example at least 15%, while the difference in residual magnetism should be for example at least 10%.
  • the metallic parts of the security element can be, as mentioned, fluorescent and therefore visible when excited by ultraviolet rays, or also the nonmetallic parts can be covered entirely by inks or pigments with fluorescent characteristics, or the metallic parts can have dichroic characteristics.
  • the invention also relates to a system for reading a security element as defined above, comprising means which are adapted to identify the placement of magnetic elements arranged above or below the at least one metalized layer, when the magnetic elements are deposited on the edges of the security element.
  • the system comprises means adapted to identify the presence of magnetic inks with a different coercivity of the magnetic elements arranged above or below the metalized layer, when the magnetic elements are deposited on the edges of the security element by using the different residual magnetism obtained by rotating the magnetic orientation of the magnetic elements that are printed with a lower coercivity than magnetic elements with a higher coercivity (for example 300 oe for the low-coercivity elements and 3500 oe for the high-coercivity elements).
  • the materials used may be any according to requirements and to the state of the art.
