Definitions

  • the invention relates to a method for producing a multilayer security element which has at least one effect layer which requires a special substrate.
  • Valuables such as branded goods or documents of value are often provided with 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.
  • optically variable elements are used as security elements, which give the viewer a different image impression, for example a different color impression, at different viewing angles.
  • holograms holographic grating images and other hologram-like diffraction structures are used for authenticity assurance, which offer the viewer a viewing angle-dependent diffraction pattern.
  • Security elements with hologram-like diffraction structures are transferred, inter alia, in the transfer process to the target substrate, for example a banknote.
  • the detachment of the security element from the carrier film takes place either via so-called release layers, which are usually thermally activated, or by the low adhesion of the security element on the carrier film.
  • the security element is coated with a suitable adhesive system.
  • Other security features such as luster pigments or other optically variable effect colors, are usually printed directly onto a paper substrate. The brilliance and the visual impression of the respective security element depend strongly on the ground.
  • the publication US 2003/189684 A1 relates to an anisotropic polymer film with improved alignment on a substrate having a structured surface.
  • the object of the invention is to provide a method which avoids the disadvantages of the prior art.
  • liquid-crystalline materials can be aligned in a simple manner and then transferred to any other layer sequence, which in itself has no corresponding properties.
  • the invention offers the advantage that the alignment layer does not have to be provided in the layer composite of the security element. Because the orientation of the liquid-crystalline material takes place on a separate carrier film and then only the liquid-crystalline material is transferred to the layer structure of the security element.
  • effect layers that require a special substrate.
  • Deposited, optically variable layers such as e.g. Diffraction structures, interference layer pigments, liquid crystal pigments or metallic effect pigments, for example, require a very smooth substrate in order to achieve a brilliant color impression or a reflecting surface.
  • the background layer in the desired layer sequence of the security element is not sufficiently smooth, as e.g. in the case of magnetic layers, such layers can be prepared on an optimally prepared substrate of a plastic carrier film and then inserted at the desired location in the layer structure of the security element, e.g. on a rough magnetic layer.
  • an adhesive layer is used, which also compensates for the rough ground.
  • the security element can be provided with further functional layers, such as electrically conductive, luminescent, magnetic layers, or any imprints. Other layers produced by the process according to the invention can also be incorporated.
  • the invention contains a method for producing a first composite layer according to claim 1.
  • the removability of the carrier film is ensured by a release layer, which under the appropriate transmission conditions supports the separation of the carrier film from the effect layer and the transfer assist layer.
  • a heat-sealable thermally activatable release layer is used.
  • the effect layer advantageously forms an optically effective effect layer or a mirror-effect effect layer.
  • a lacquer layer of oriented liquid-crystalline material or a layer with optically variable or metallic pigments, which are preferably printed, is suitable as the effect layer.
  • the effect layer is preferably applied partially, in particular in the form of patterns, characters or codes.
  • liquid-crystalline effect layers representative of any other effect layers.
  • Such liquid crystalline effect layers show, as explained in detail below, certain polarization or color effects.
  • the liquid-crystalline material is preferably applied directly to the plastic carrier film without further alignment layers, preferably printed. Preferably, the liquid crystalline material is partially applied.
  • transfer assist layer also makes it possible to transfer security elements made of liquid-crystalline material which are not present over the entire area, for example printed as a motif, onto a target substrate. If desired or necessary, the carrier film for the liquid-crystalline layer and the transfer assist layer may be at or after the application of the transfer material to the target substrate are removed.
  • liquid-crystalline material may be applied partially, in particular in the form of patterns, characters or codes, between the liquid-crystalline layer and the transfer assist layer. These may advantageously overlap at least partially with the first applied liquid-crystalline layer.
  • the liquid-crystalline layers are advantageously applied as a lacquer layer of smectic, nematic or cholesteric liquid-crystalline material, preferably printed.
  • Gravure printing, screen printing, flexographic printing, knife or curtain coating are particularly suitable as printing techniques for the liquid-crystalline layers and / or the transfer assist layer.
  • this can also be formed by a reflective thin-film element.
  • a reflective thin-film element is preferably formed with a reflection layer, an absorber layer and a dielectric spacer layer arranged between the reflection layer and the absorber layer.
  • a transfer material of the kind described with the adhesive layer is placed on the target substrate and bonded to the target substrate by heat and / or pressure.
  • the transfer material is advantageously connected to the target substrate by pressure and radiation.
  • the plastic carrier film of the possibly partially present effect layer is expediently removed during or shortly after application to the target substrate.
  • Valuables within the meaning of the present invention are in particular banknotes, stocks, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other counterfeit-endangered papers, such as passports and other identification documents, as well as product security elements, such as labels, seals, packaging and the like.
  • object of value in the following includes all such objects, documents and product protection means.
  • security paper is understood to mean the precursor that can not yet be processed to a value document, which besides the security element can have further authenticity features, such as, for example, luminescent substances provided in the volume. security paper is usually in quasi endless form and will be further processed at a later date.
  • the detachability of the carrier film 42 during the transfer is ensured by a release layer 44 that can be thermally activated under heat-sealing conditions.
  • a desired embossed structure 64 for example a diffraction structure, is impressed into the embossing lacquer layer 62 and a reflective layer 66, in particular a metal layer, is applied, into which recesses 68, in the example in the form of a negative writing, are introduced by partial demetallization.
  • the embossing structure 64 may also be provided with a high refractive index layer. Examples of high-index materials are CaS, CrO 2 , ZnSi, TiO 2 or SiO x .
  • an adhesive layer 38 is applied to the composite layer for transfer to the target substrate.
  • the embossing lacquer layer 102 on the transfer assist layer 36 is advantageously subjected to a corona treatment beforehand or it is provided with a suitable adhesion promoter.
  • An adhesive layer 38 is applied to the entire layer composite for transfer to the target substrate.
  • the carrier film 32 can be removed after the application of the transfer material 100 or left on the structure.
  • a second layer composite 114 is produced by applying to a second carrier film 120 a screened aluminum layer 122 with recesses in the form of negative writing, and onto the aluminum layer a magnetic layer 124, in the example in the form of a coding, is applied.
  • This second layer composite 114 is in Fig. 10 (b) shown.
  • the aluminum layer 122 may also be provided as a full-surface layer with recesses, for example in the form of negative writing, to which in turn the magnetic layer 124 is applied.
  • a dark, in particular black layer with recesses and regions a magnetic layer for example in the form of magnetic bits.
  • not all black areas need to be magnetic at the same time. In this way, a magnetic coding in the black layer can be optically hidden.
  • the security element 70 is placed on the target substrate 200 with the heat-sealable adhesive layer 38 and pressed in areas.
  • the pressing can be done for example with a not shown heated transfer punch or a transfer roller.
  • the adhesive layer 38 connects in the desired regions 202 with the target substrate 200, so that a transfer element, if appropriate with a predetermined outline shape, arises.
  • the carrier film 32 of the liquid crystal layers 34, 36 can be removed during the application process or shortly thereafter.
  • the detachability of the carrier film from the effect layer can also be ensured by a release layer assisting the separation under the appropriate transfer conditions.
  • the carrier film can then additionally comprise, for example, a release layer thermally activatable under heat-sealing conditions, as in the exemplary embodiment of US Pat Fig. 4 is illustrated on which then the effect layer is applied.
  • an adhesive layer is further applied to the effect layer.
  • the adhesive layer can also be provided on the second layer composite. If desired or required, the carrier film can be removed by separation winding last.
