Definitions

  • the invention relates to an embossing film, in particular Hot stamping foil, consisting of a carrier film and a from this removable transfer situation, which - starting from the carrier film - at least a transparent one Protective lacquer layer, one of at least one layer educated, decorative or securing elements comprehensive decorative layer structure and one for fixing serving the transfer layer on a substrate Has adhesive layer.
  • stamping foils in particular hot stamping foils
  • the adhesive layer which is generally a hot glue or radiation curable Kleber acts
  • the transfer situation should not be transferred over the entire surface to the substrate but only certain areas of the transfer situation, for example, decorative elements in the Transfer situation in a manner known per se Printing processes etc. are generated.
  • securing elements for example on Securities such as banknotes, credit cards, ID cards etc. or other objects to be secured are also in large amount of hot stamping foils used. It is it is important that only the respective securing element or the the area corresponding to the securing element Transfer layer detached from the carrier film and on the substrate is set.
  • the invention is therefore based on the object Stamping foil, especially hot stamping foil, such to train that without special measures precise registration of individual areas of the Transfer layer in the form of decorative or Securing elements on a substrate is possible, but not particularly for transfer to the substrate shaped stamps are required but for example Rolls or rollers can be used. Furthermore it should also in a procedure according to the invention be possible, the transfer situation much more stable and to train mechanically more resistant.
  • an embossing foil in particular Hot stamping foil of the type mentioned above train that at least the adhesive layer only in some areas and with register that only locally trained decoration or Securing elements of the transmission position is provided, and the protective lacquer layer over the entire surface of the carrier film covers.
  • EP 0 461 475 describes an embossing film for transferring a Decor on a substrate known, one on a separate Carrier film provided adhesive layer is provided. Since the Transfer layer and the adhesive layer on two different Carrier films are arranged is the exact transfer of individual Elements from the transfer situation are only possible to a limited extent, since that Transfer must be done in two steps, first the transfer the adhesive layer and secondly the transfer of the Transfer situation.
  • a transfer film is also known from EP 0 413 819, at which in particular has a shiny metallic pattern on a substrate is transmitted, the shape of this pattern being determined by the shape of the Adhesive layer is determined because of the transfer layer and therefore also only transfer the metal layer to the substrate at the points on which an adhesive layer is provided. It is an embodiment of one Transfer film reveals the adhesive layer and above Metal layer correspond to each other. This is done in an elaborate process Procedure allows first on a corresponding Underlay a metal layer is applied over the entire surface subsequently in a predetermined pattern with an adhesive layer is provided. In a further step, the will not be through the adhesive layer covered metal layer with an acid or alkaline caustic solution removed.
  • embossing foil according to the invention is also preferred in it see that a perfect match of Adhesive layer in some areas with the transferring areas of the transfer situation without Difficulties can be achieved because of the usual both the various layers of the transfer situation as well the adhesive layer is applied in a printing process become. It is well known that when printing, the perfect one Alignment of different, superimposed layers no difficulties.
  • embossing foils according to the Invention also for substrates with a very rough surface, for example paper, with excellent adhesion and physico-chemical resistance can.
  • embossing film according to the invention offers thus both considerable compared to the usual Advantages in terms of being transferred to the substrate usable tools, and especially with regard to Accuracy in the delineation of the substrate areas of the transfer layer to be applied.
  • Farther allows the stamping foil according to the invention with the only Adhesive layer provided in certain areas in a variety of cases the use of mechanically essential more stable layers for the transfer layer. Even if in such a case during the transmission of the Limiting the area of the Transfer situation is not clean, can very easily in a further operation possibly over the adhesive layer protruding transfer layer material are removed, because in the area of the adhesive layer, the transfer layer very much adheres firmly to the substrate.
  • a release layer be provided, it being particularly advantageous if according to the invention, the release layer only in some areas and is provided in register with the adhesive layer.
  • Such Formation of the stamping foil causes the Transfer situation in the areas where there is no peel layer is present, these areas with the areas match where no adhesive layer is provided, adheres comparatively firmly to the carrier film, as a result of which Tear off or the separation of the transfer layer along the edge of the area to be transferred is supported.
  • the spatial Structured side of the protective lacquer layer Have coating whose optical properties differ differ from those of the protective lacquer layer, the Coating in particular from a reflective Material, preferably metal, is formed.
  • the spatial structures according to the invention in are generally in register with the adhesive layer, it is particularly beneficial if the coating takes place over the whole area, and that because Coatings over the entire surface much lighter and in front all without additional measures or work steps have it attached. Nevertheless, the full surface is annoying Coating usually not because of the layer thickness such coatings are so small that they Transfer to the substrate easily along the Edge of the areas bearing the adhesive layer.
  • the coating also partially and in register spatial structure can be attached to make a special to achieve clean delimitation of the transferred layers.
  • the Peel off the areas the adhesive layer and / or the decorative or Safety elements protrude on all sides by at least 0.2 mm.
  • Surviving the protective lacquer layer and possibly the Removal layer over the decorative or securing elements and at the same time over the adhesive layer offers the advantage that the protective lacquer layer along during the transfer process its edge is applied closely to the substrate, being in general also the protruding area of the Protective lacquer layer adheres perfectly to the substrate because the Adhesive layer due to its thickness, even if only small still compressed during the transfer process and with it outwards towards the edge of the Protective lacquer layer is pressed.
  • Figures 1 and 2 show sections, each in section from the corresponding hot stamping foils. In this context it should be noted that the Thickness of the different layers not to scale is shown.
  • the hot stamping foils each comprise a carrier film 1, for example one Polyester film with a thickness of approx. 20 ⁇ m.
