Definitions

  • the invention relates to a strip-like continuous film with a multiplicity of security elements, each of which is designed as a transfer element that can be detached from the continuous film for application to security paper, a valuable object or the like.
  • the invention further relates to the use of the strip-like continuous film for securing security paper or an object of value.
  • Valuables such as branded articles or documents of value
  • security elements for security purposes, which allow the authenticity of the object of value to be checked and which also serve as protection against unauthorized reproduction.
  • Valuable objects in the sense of this invention are, in particular, banknotes, shares, ID cards, credit cards, health cards, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other papers that are susceptible to counterfeiting, such as passports and other identification documents, as well as product security elements such as labels, seals, packaging, Branded goods and the like.
  • the term “valuable object” includes all such objects, documents and product securing means.
  • security paper is understood to mean the preliminary stage to a value document that is not yet fit for circulation.
  • security paper also includes paper-like substrates below, e.g. Plastic substrates or multilayer substrates such as a plastic / paper / plastic substrate or a paper / plastic / paper substrate.
  • a security element is usually provided with a functional layer having a security feature, e.g. a hologram or an optically variable coating. It is particularly expedient if the security element by means of an adhesive, e.g. by means of a heat seal lacquer, onto the object of value or the security paper.
  • a security element is e.g. a patch, especially a hologram patch.
  • the security element is usually provided together with further security elements on a strip-shaped continuous film serving as a carrier and is transferred from there to the surface of a security paper or valuable object. Since the carrier film is removed from the surface of the security element when the security element is applied to the security paper or to the object of value, the term (endless) transfer film or (endless) transfer ribbon and instead of the term security element is replaced by the term Term used transfer element.
  • a strip-like continuous film is provided as a roll, i.e. as an endless belt, so to speak, wound on a roll, the continuous film of course not being endless and thus infinitely long, but in particular having a length in the range of kilometers.
  • Machines for applying security elements to the surface of security paper or a valuable item are commercially available, e.g. OptiNota H® from König & Bauer AG.
  • Such a device enables the precise or register-accurate application of security elements in the form of film strips on sheets of paper.
  • the film strip is applied in that a specific section of the strip-shaped continuous film (hereinafter referred to as "film strip section”) comes into contact with a heated roller and is heated in this way. The heating leads to a softening of the heat seal lacquer present on the surface of the film strip section.
  • the film strip section is then glued to the paper sheet by means of the melted heat-sealing lacquer.
  • thermoplastic embossing lacquer In practice it has been shown that the hot roller application of foils based on thermoplastic embossing lacquer is not a problem. In films with embossing varnish based on UV varnish, however, the brittleness of the UV varnish led to the formation of tinsel in the course of the tearing described in the previous paragraph.
  • tinsel formation means the removal of dust, crumb and chip-shaped parts from the cut surface. The flakes arise when the UV varnish is broken and have a disruptive effect on the subsequent processing steps in (value document) printing. In particular, malfunctions in the printed image can occur when placing tinsel on printing rollers within printing machines.
  • the UV varnish within a strip of film applied to a sheet of paper must be broken after application at the beginning and end of the sheet of paper. A clean, smooth breaking of the UV varnish by means of laser cutting is not possible in the case of a transfer film because the carrier film also has to be removed.
  • EP 0 675 006 A1 shows a strip-shaped continuous film with a front and a back, wherein the front has a plurality of security elements, which are arranged spaced apart in the longitudinal direction of the strip-shaped continuous film and are each designed as a transfer element that can be detached from the continuous film for application to security paper or a valuable object, and
  • Each security element starting from the front of the continuous film, has a functional layer with a length F and a layer of heat-seal adhesive with a length H arranged above the functional layer, the lengths F and H being related to the longitudinal direction of the strip-shaped continuous film and fulfill the relationship F ⁇ H and the functional layer having a security feature and the layer of heat-sealing adhesive are such that the functional layer is U-shaped from the layer of heat-sealing adhesive is surrounded.
  • the functional layer comprises an embossing lacquer layer with a diffraction structure.
  • the present invention is based on the object of providing a strip-shaped continuous film which is improved compared to the prior art and the use thereof for securing a security paper or an object of value.
  • This object is achieved by the combinations of features defined in the independent claims.
  • the combinations of features defined in the dependent claims represent preferred embodiments.
  • Figure 1 and Figure 2a refer to a comparative example. For the sake of clarity, the figures are not drawn to scale and proportion.
  • Figure 1 shows a schematic representation of a paper sheet 1, on which four transfer film strips 2 have been applied according to the prior art.
  • the paper sheet 1 shown in the figure can be printed in subsequent steps, for example by means of screen, flexographic and intaglio printing processes, and finally cut into a large number of documents of value, in particular bank notes.
  • the applied transfer film strips 2 come from a strip-like continuous film.
  • the transfer film strips 2 were applied in that defined sections of the strip-shaped continuous film came into contact with a heated roller and were heated in this way. The heating led to a softening of the heat seal lacquer present on the surface of the defined film strip sections.
  • the film strip sections were then glued to the paper sheet 1 by means of the melted heat-sealing lacquer.
  • the transfer film strip 2 shown contains, among other things, a continuous or continuous UV embossing lacquer layer in its layer structure. Due to its brittleness, the UV varnish tends to form tinsel. As can be seen from the enlargement of the section "A" shown to the left of the paper sheet 1, there are unclean breaking edges and broken pieces or tinsel 3. The tinsel 3 arise when the UV lacquer is broken 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 continuous film 4 according to the prior art, which in the in the Figure 1 Comparative example shown was used.
  • the endless film 4 contains a carrier film 5, in the present case a PET film.
  • a UV embossing lacquer layer 6 Above the carrier film 5 there are a UV embossing lacquer layer 6, a primer layer 7 and a heat seal lacquer layer 8 in sequence. It is characteristic of the layer structure of the strip-like continuous film 4 according to the prior art that each of the UV lacquer layer, primer layer and heat seal lacquer layer is in shape there is a continuous or continuous layer.
  • the adhesive 8 does not bond to the paper, so that the layers 6, 7 and 8 remain on the carrier film 5 within this section.
  • the adhesive 8 is connected to the paper, so that the layers 6, 7 and 8 are applied to the paper within these sections and later from the carrier film 5 serving as a transfer film be replaced.
  • the two in the Figures 2a to 2e The vertical straight lines 14 shown illustrate the predetermined breaking edges within the security element layer structure present on the carrier film 5.
  • the UV lacquer 6 has to be broken at the points of the breaking edges, which is what in the Figure 1 shown bauble 3 results.
  • FIG. 2b shows a schematic representation of the layer structure of a strip-shaped continuous film 9 according to a first embodiment of the invention.
  • the UV embossing lacquer layer 6, the primer layer 7 and the heat-sealing lacquer layer 8 are each recessed in the continuous film 9. By cutting out the UV lacquer 6, the UV lacquer is prevented from breaking and thus the formation of tinsel.
  • the continuous film 9 is produced by providing the carrier film 5 (for example a PET film) and printing the carrier film 5 with a UV lacquer layer 6 which has cutouts. Subsequently, a primer layer 7 and a heat seal lacquer layer 8 are printed successively, each of which has recesses.
  • the primer layer 7 has larger dimensions than the UV varnish 6.
  • the heat seal lacquer layer 8 in turn has larger dimensions than the primer layer 7.
  • Figure 2c shows a schematic representation of the layer structure of a strip-shaped continuous film 10 according to a second embodiment of the invention.
  • the endless film 10 has a continuous or continuous separating layer or release layer 11 which facilitates the detachment of the security element layer structure comprising the layers 6, 7 and 8 from the carrier film 5.
  • the continuous film 10 is produced by providing the carrier film 5 and printing the entire area of the carrier film 5 with a release layer 11. This is followed by printing the release layer 11 with a UV lacquer layer 6 which has cutouts. Subsequently, a primer layer 7 and a heat seal lacquer layer 8 are printed successively, each of which has recesses.
  • the primer layer 7 has larger dimensions than the UV varnish 6.
  • the heat-sealing lacquer layer 8 in turn has larger dimensions than the primer layer 7.
  • the release layer 11 prevents the primer layer 7 and the heat-sealing lacquer layer 8 from being connected to the carrier film 5 Sticking to the paper, ie after the heat sealing process, does not cause the paper to tear because the primer 7 has no direct contact with the film 5.
  • the primer 7 and the heat seal lacquer 8 each have larger dimensions.
  • This "lengthwise protrusion" of the primer 7 or the heat sealing lacquer 8 compared to the UV lacquer 6 is expediently in an area in which, due to the machine, there is still a sticking to the paper, that is to say a heat sealing.
  • Figure 2d shows a schematic representation of the layer structure of a strip-shaped continuous film 12 according to a third embodiment of the invention.
  • the exemplary embodiment shown is not formed continuously or continuously, but rather discontinuously, the separating layer or release layer 13.

  • 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 running perpendicular to the longitudinal direction of the strip-shaped continuous film.
  • the separating layer arranged between two adjacent security elements has no recess, that is to say the separating layer arranged between two adjacent security elements is formed continuously.
  • the larger dimension of the separating layer compared to the third exemplary embodiment is advantageous because the separating layer is easier to produce by printing on the film.
  • Figure 2f shows a schematic representation of the layer structure of a strip-shaped continuous film 12 according to a fifth embodiment of the invention.
  • the fifth embodiment is a modification of the third embodiment ( Fig. 2d ).
