Definitions

  • the invention relates to a strip-shaped endless film with a plurality of security elements, each of which is designed as removable from the endless foil transfer element for application to a security paper, a valuable item or the like.
  • the invention further relates to the use of the strip-shaped endless foil for securing a security paper or a valuable item.
  • Valuables such as branded goods or documents of value
  • security elements for the purpose of security, which allow verification of the authenticity of the object of value and at the same time serve as protection against unauthorized reproduction.
  • Valuables for the purposes of this invention are in particular banknotes, shares, identity cards, credit cards, health cards, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other papers that are subject to counterfeiting, such as passports and other identity documents, as well as product security elements such as labels, seals, packaging, Branded articles and the like.
  • the term valuable item includes hereinafter all such items, documents and product protection means.
  • security paper is understood as the precursor to a value document which can not yet be processed.
  • security paper also includes paper-like substrates, e.g. Plastic substrates or multi-layer substrates, such as a plastic / paper / plastic substrate or a paper / plastic / paper substrate, a.
  • a security element is usually provided with a function layer having a security feature, for example a hologram or an optically variable coating. It is particularly useful if the security element by means of an adhesive, for example by means of a heat sealing lacquer, is glued to the valuables or the security paper.
  • a security element is eg a patch, in particular a hologram patch.
  • the security element is usually provided together with other security elements on a serving as a carrier, strip-shaped continuous foil and transferred from there to the surface of a security paper or a valuable item. Since the carrier film is removed in the application of the security element on the security paper or on the object of value from the surface of the security element, hereinafter the term (endless) transfer film or (endless) transfer belt and instead of the term security element of the term Term transfer element used.
  • a strip-shaped continuous film is provided as a roll product, i. as an endless belt wound on a roll, so to speak, wherein the endless film is of course not endless and thus infinitely long, but in particular has a length in the range of kilometers.
  • Machines for applying security elements to the surface of a security paper or a valuable item are commercially available, eg OptiNota H® from König & Bauer AG.
  • Such a device allows the exact fit or register accurate application of security elements in the form of film strips on paper sheets.
  • the film strip is applied by bringing a certain portion of the strip-shaped endless foil (hereinafter referred to as "foil strip section") into contact with a heatable roll and thus heating it. The heating results in softening of the heat sealing lacquer present on the surface of the foil strip section. Of the Film strip section is then bonded to the paper sheet by means of the molten heat seal lacquer.
  • the foil strip section described in the preceding paragraph simultaneously defines the two breaklines at which the security element structure ruptures. All layers above the carrier film in the security element structure, in particular an embossing lacquer layer, tear during detachment or removal of the carrier film at the point at which the endless film did not come into contact with the heated roller.
  • thermoplastic embossing-based films In practice, it has been found that the hot roll application of thermoplastic embossing-based films is not a problem.
  • thermoplastic embossing varnish films due to the brittleness of the UV varnish, tearing occurred in the course of the rupture described in the preceding paragraph.
  • tinsel formation refers to the detachment of dust, crumbs and chip-shaped parts from the cut surface.
  • the baubles are formed when the UV varnish breaks and have a disruptive effect on the subsequent processing steps during (value-document) printing. In particular, when depositing flakes on printing rollers within printing presses, disturbances in the printed image may occur.
  • the UV varnish within a foil strip applied to a paper sheet must be broken after application at the beginning and at the end of the paper sheet.
  • a clean, smooth breaking of the UV lacquer by means of laser cutting is not possible in the case of a transfer film, because in addition the carrier foil has to be removed.
  • the object of the present invention is to provide a strip-shaped endless foil which is improved over the prior art and its use for securing a security paper or a valuable article.
  • This object is achieved by the feature combinations defined in the independent claims.
  • the feature combinations defined in the dependent claims represent preferred embodiments.
  • FIGS. 2b, 2c, 2d . 2e . 3 and 4 The invention will be described below on the basis of exemplary embodiments ( FIGS. 2b, 2c, 2d . 2e . 3 and 4 ).

  • the paper sheet 1 shown in the figure can be printed in subsequent steps, for example by means of screen, flexo and intaglio printing methods, and finally cut into a multiplicity of value documents, in particular banknotes.
  • the applied transfer film strips 2 originate from a strip-shaped endless foil.
  • the application of the transfer film strips 2 was carried out by having defined sections the strip-shaped endless film with a heated roller in contact and were heated in this way. The heating resulted in softening of the heat sealing lacquer present on the surface of the defined film strip sections.
  • the film strip sections were then bonded to the paper sheet 1 by means of the molten heat-sealing lacquer.
  • the Indian FIG. 1 shown transfer film strip 2 contains in its layer structure, inter alia, a continuous or continuous UV embossing lacquer layer. Due to its brittleness, the UV varnish tends to form baubles. As can be seen from the enlargement of the detail "A" shown to the left of the paper sheet 1, unclean break edges and breakouts or flakes 3 occur. The baubles 3 are formed when the UV coating breaks and impair the printability of the paper sheet 1 in the subsequent printing process.
  • FIG. 2a shows a schematic representation of the layer structure of a strip-shaped endless foil 4 according to the prior art, which in the in the FIG. 1 Comparative example shown was used.
  • the endless foil 4 contains a carrier foil 5, in the present case a PET foil.

  • the primer layer 7 has larger dimensions than the UV lacquer 6.
  • the heat sealing lacquer layer 8 in turn has larger dimensions than the primer layer 7.
  • the release layer 11 prevents a connection of the primer layer 7 and the heat sealing lacquer layer 8 with the carrier foil 5. This occurs after the gluing with the paper , ie, after the heat-sealing operation, not to a tearing of the paper, because the primer 7 has no direct contact with the film 5. Compared with the dimensions of the UV varnish 6, the primer 7 and the heat sealing varnish 8 each have larger dimensions. This "lengthwise protruding" of the primer 7 or of the heat-sealing lacquer 8 with respect to the UV lacquer 6 is expediently in a region in which, due to the machine, gluing to the paper, ie to heat-sealing, occurs.
  • Figure 2d shows a schematic representation of the layer structure of a strip-shaped endless foil 12 according to a third embodiment of the invention.
  • the release layer or release layer 13 is not continuous or continuous, but formed discontinuously.
  • a good initial peel ie, a good "initial release”
  • the UV lacquer 6, primer 7, and heat sealing lacquer 8 having the security element layer build-up from the carrier foil 5 and gluing of the primer 7 to the carrier foil must be ensured 5 are prevented.

  • the release layer or release layer 13 is not continuous or continuous, but formed discontinuously.
  • the separate separating layer regions 13 are arranged such that each security element has exactly one separating layer region at each of its two ends extending perpendicular to the longitudinal direction of the strip-shaped endless foil.
  • the separating layer arranged between two adjacent security elements has no recess, ie the separating layer arranged between two adjacent security elements is formed continuously.
  • the dimension of the separating layer which is increased in comparison to the third exemplary embodiment, is advantageous because the separating layer can be produced more easily by printing on the film by printing technology.
  • FIG. 2f shows a schematic representation of the layer structure of a strip-shaped endless film 12 according to a fifth embodiment of the invention.
  • the fifth embodiment is a modification of the third embodiment ( Fig. 2d ).

  • the endless film 12 is produced by providing the carrier film 5 and applying, for example, printing on the carrier film 5 with a discontinuous separating layer or release layer 17. This is followed by the application of a UV coating layer 6 which has recesses. The beginning of each recess of the UV lacquer layer 6 is in the region of the release layer 17. Subsequently, a further UV lacquer layer 6a applied, which also has recesses. The recess of the further UV lacquer layer 6a are larger than the recesses of the UV lacquer layer 6, so that the (further) UV lacquer layer 6a does not envelop the UV lacquer layer 6.
