Definitions

  • the invention relates to security paper, in particular banknote paper.
  • Papers are already known which include strips or threads consisting of a transparent film provided with a continuous metallic layer, for example aluminum deposited under vacuum on polyester. Such threads, when introduced into paper which is then printed, are barely seen by the public in reflected light and become much more apparent in transmitted light.
  • the purpose of these wires is to prevent a counterfeiter, from a common paper, from imitating an authentic document, by printing on this paper a dark line on the surface. In this case of counterfeiting, there is no difference between the visibility of the line in reflection and in transparency.
  • EP-A-279 880 describes a transparent wire comprising metallic micro-prints obtained for example by demetallizing areas not protected by varnish. The prints are barely visible by reflection and more visible by transparency using a magnifying device.
  • the invention aims to provide a support comprising a security element betraying falsification.
  • Another object of the invention is therefore to provide a support comprising a security element which also retains certain detectable security indices after an attempt to whiten the surface of the support.
  • the invention therefore relates to a printable security support comprising security elements betraying falsification. These security elements are such that they include at least hidden means for recognizing falsification.
  • the security element consists of an element at least partially coated with a layer sensitive to falsifying agents and provided at least partially with an agent resistant to falsifying agents, said resistant agent possibly forming a design, a model.
  • the layer sensitive to falsifying agents is a layer sensitive to agents chosen from the group of strong bases or polar solvents.
  • the sensitive layer is, for example, a metal layer sensitive to alkalis such as aluminum.
  • the resistant agent is, for example, a colorless or colored impression. This impression can be obtained from an ink which may contain a pigment chosen from the group of mineral, organic and metallic pigments. This impression can also be obtained by chemical deposition of a metal which is inert towards the forging agents.
  • the flexible element is made of a synthetic material, for example polyester.
  • the security element consists of a polyester strip comprising on one side a metallic coating provided with prints resistant to falsifying agents.
  • the security element may consist of a polyester strip having on one side a metallic coating and on the other side of impressions resistant to falsifying agents.
  • the security element may consist of a polyester strip having on one side an imprint not sensitive to polar solvents and on the opposite face or the same face an imprint sensitive to polar solvents.
  • the support is for example a sheet of paper obtained by the wet method and made up of cellulosic fibers, optionally synthetic fibers, binders, fillers. It can be made of a sheet of synthetic material, possibly coated with a layer to improve printing.
  • the invention further relates to a method of manufacturing a support according to which: a flexible sheet is covered with a metallic layer, for example aluminum, - the flexible sheet is printed on one of the faces using an ink resistant to falsification agents, - the flexible sheet thus coated and printed is cut, to make fibers, continuous threads or boards, - Introducing the fibers, son or boards thus obtained at least partially inside a printable medium.
  • a metallic layer for example aluminum
  • the invention relates to a method of manufacturing a support according to which: a flexible sheet is covered with a metallic layer, for example aluminum, an impression is made by chemical deposition of a metal, for example nickel on one of the faces of the flexible sheet, - the flexible sheet thus coated and printed is cut, to make fibers, continuous threads or boards, - Introducing the fibers, son or boards thus obtained at least partially inside a printable medium.
  • a metallic layer for example aluminum
  • the security support 1 is planar and printable. It comprises a security element 2 which is arranged at least partially between the upper and lower faces of the support 1.
  • FIG 1 there is shown a security element 2 which is completely disposed inside the support 1.
  • this security element 2 is visible to the naked eye in transparency, that is to say in transmitted light. On the other hand, in reflected light, it is much less visible.
  • this security element 2 seems identical to a security element of the prior art, namely a polyester thread covered with a continuous metallic layer.
  • this security element 2 includes hidden means of recognition 3 for falsification, these means being reactive to falsification agents.
  • the support 1 having on the surface impressions 3 which indicate for example the value 4 of the cut.
  • the security element 2 is an element, for example a wire or a fiber, or a confetti, or a board coated with a layer sensitive to falsification agents and provided with at least partially of a protective agent for the sensitive layer, this agent being resistant to falsifying agents.
  • a person skilled in the art is capable, by knowing the falsifying agents, of choosing a layer sensitive to these agents and a protective agent resistant to the same agents.
  • the falsifying agents are bases
  • the person skilled in the art may choose to coat the element (wire, fiber, confetti) with a metal dissolving at the bases and to provide the element with a partial layer or total of a base resistant varnish.
  • An exemplary embodiment is to coat a polyester thread 5 (FIG. 1) with a layer 6 of aluminum and to print using a colorless varnish 7 above the aluminum layer, this varnish being resistant to bases, a dark wire 8 is obtained such as in FIG. 4A.
  • the wire is introduced into a paper or any other support. This wire is visible in transmitted light and much less visible in reflected light.
  • the paper is then printed on the surface to form, for example, a bank note.
  • the counterfeiter uses a basic solution, possibly with detergent solutions, the aluminum layer will be dissolved and as the varnish is resistant to bases, an impression 9 will appear, which will be visible in transparency, while the paper will become without impression in area. The wire will therefore not be visible to the counterfeiter ( Figure 3), in reflection.
  • Another embodiment is to coat a polyester sheet totally of aluminum, on one side, and totally of varnish on another side, this varnish being resistant to bases and being colored.
  • This sheet is cut into confetti or boards which are introduced into a paper, which is then printed on the surface.
  • these boards appear greyish, and if a counterfeiter tries to whiten the paper to remove the impression the aluminum will be dissolved, while the colored varnish will remain.
  • the boards will therefore appear colored, after an attempt at falsification.
  • the varnish can comprise, according to another example, fluorescent dyes, resistant to bases.
  • fluorescent dyes resistant to bases.
  • the security elements according to the invention are distinguished from the elements of the prior art. Indeed, the latter never use the layer layer sensitive to falsifying agents / agent resistant to falsifying agents.
  • Application EP-A-319 157 describes a wire which may include metallic inks in the form of printing or a wire which has been demetallized for example by means of a laser beam. This wire, once introduced into the paper, if it is subjected to a base, loses its metallic impression, but in no case does it appear after falsification a means of recognizing the falsification, this means being invisible before falsification.
  • Another embodiment of the invention is the deposition of aluminum on one side of the polyester 11 (FIG. 5) and the chemical deposition (to form a pattern) of a metal resistant to the bases, for example nickel.
  • a metal resistant to the bases for example nickel.
  • the security element may be introduced into a support which may be paper containing more or less synthetic or mineral fibers, or else the support may be a sheet of printable synthetic material, such as the POLYART® sold by the applicant.
  • a safety thread according to the invention is produced as follows: a polyester support 23 microns thick is metallized on one side. This metallization is obtained by spraying aluminum under vacuum. The thickness of aluminum deposited will depend on the desired opacity of the security wire; 700 angstroms for example. On the aluminized face of the wire are printed characters with an ink of the following composition: - Synolite 595 resin 100 games - Terbutylperoxybenzoate 1 part
  • the printed characters are dried at 130 ° C. These characters are transparent. A uniform safety wire of uniform color is thus obtained. This wire is introduced into the paper by known techniques.
  • a security thread is produced as in Example 2 but using an ink made up of a mixture of two inks: a white ink and a black ink. These inks have the distinction of resisting chemical attack well. Any other mineral pigment can be added to these inks to give them a special shade. The color of the ink depends on the tint of the characters that one wishes so that they become indistinguishable on the security thread after introduction into the paper. The attempted falsification, as in the previous examples, will reveal the printed text as in Example 2.
  • a safety thread according to the invention is obtained as follows: on one side of a 23 micron polyester support, printing by chemical deposition of nickel is carried out by the methods known from the prior art (Bayprint method from the company Bayer for example ). On the other side, an aluminum layer is deposited (aluminization under vacuum). This thread introduced into the paper seems quite common and does not reveal any clues. This thread reacts, as in the previous examples, to attempts at falsification.
