Definitions

  • the invention relates to a transfer film, consisting from a carrier film and at least one by means of heat and / or pressure in some areas removable from the carrier film paint layer transferable to a substrate.
  • Such transfer films are from DE-A 3 401 677 and from known from US-A 3 961 121.
  • This Films comprise a carrier film on which one Decorative layer arrangement is provided by means of heat and / or pressure is removable from the carrier film and on the Substrate can be transferred.
  • the decorative layer arrangement the hot stamping foils usually consist of several, relatively stable layers of paint and is by means of a special adhesive layer on the substrate.
  • the Lacquer layers are applied to the in a printing process Carrier film applied. In this way it is possible to produce appropriate decors, which are then on the Substrate that is decorated with the hot stamping foil, appear.
  • Hot stamping foils For transferring the decorative layer arrangements from Hot stamping foils must with sufficient pressure and sufficient temperature can be worked to ensure a clean Removal of the areas to be transferred To ensure decorative layer arrangement on the substrate because the decorative layer arrangement is relatively large Has stability. This means that it is proportionate stable tools must be used.
  • a Processing of hot stamping foils in the example of Thermal printers known way is not possible because the printheads of thermal printers not those for Transfer of the decorative layer arrangement of hot stamping foils pressures and temperatures required on the substrate to reach.
  • thermal transfer printing too decorate, especially to label.
  • a corresponding one from a carrier film Transfer thermal transfer layer to the substrate e.g., a corresponding one from a carrier film Transfer thermal transfer layer to the substrate.
  • the known thermal transfer layers allow it Working with relatively short temperature pulses and low pressure, which allows using suitable printheads build fine resolution, which also, for example Generation of numbers and letters regarding the Arrangement of the different dots can be varied continuously can.
  • Hot stamping foils have been increasing in recent times Scope for applying security features various substrates used. For example it is known, diffractive optically effective fine structures in the To form a decorative layer arrangement of a hot stamping foil and they are hot stamped onto a substrate, e.g. a Security, a credit card, ID or the like transfer. In these areas of application more often the desire not only with the document of value Security feature, which is for the whole series of value documents is the same.
  • an individualization of the Value document for example by specifying the Name of the holder of an ID card, by attaching a Code number etc., with the individualizing addition (Name, code number etc.) easily from document to document be changed, but after being applied to the document a change in the sense of a forgery largely should be prevented.
  • the invention is based on the object, a Possibility to propose to the machine effort reduce if a document of value on the one hand by means of a Hot stamping foil with a decorative element, for example one Security feature, and on the other hand by means of Thermal transfer printing with an individualizing License plate should be provided.
  • a transfer film of the beginning provide or use the type mentioned, which is thereby distinguishes that on the same side of the carrier film in separated fields on the one hand a Hot stamping foils known decorative layer arrangement and on the other hand, one suitable for thermal transfer printing Thermal transfer layer are provided, and that the Carrier film is a plastic film with a thickness of 3.5 to 19 ⁇ m is.
  • the transfer film according to the invention stands out thus from the fact that for the first time transmission situations are simultaneously provided on a carrier film which for different transmission methods especially suitable are, on the one hand a decorative layer arrangement for the hot stamping process and on the other hand one Thermal transfer layer for thermal transfer printing.
  • the Decorative layer arrangement on the one hand and the Thermal transfer layer, on the other hand, are each in separate fields exist, whereby "separate" is not must mean that the different fields in Are spaced from each other. You should only can be clearly distinguished from each other, however connect directly to each other.
  • Hot stamping decor on the one hand and thermal transfer printing on the other hand based on separate transfer foils on the substrate, e.g. Value document to bring up.
  • thermal transfer printing required printhead are arranged accordingly, for example in Direction of transport of the transfer film side by side.
  • Particularly good protection of the substrate transferred decorative layer arrangement on the one hand and the im Thermal transfer printing generated label on the other hand can be achieved in that according to the invention between the Carrier film and the decorative layer arrangement as well as the Thermal transfer layer a continuous, on the substrate transferable, transparent protective lacquer layer provided is.
  • This protective lacquer layer protects the decorative layer arrangement and thermal transfer layer against mechanical influences. Because the protective lacquer layer is continuous counterfeiting is also more difficult because of certain areas Changes in which the protective lacquer layer is destroyed at least with suitable instruments, e.g. a magnifying glass.
  • a particular problem in the manufacture of Transfer foils acc. the invention represents the choice of suitable carrier film. This may be to a clean To allow thermal transfer printing, not too thick and too be stiff. On the other hand, however, it must be sufficient possess thermal stability and mechanical strength, to be used as a carrier film for a hot stamping foil where, with different temperatures and pressures is worked as in thermal transfer printing. Around According to the invention, it has to meet requirements proven to be advantageous as a carrier film To use polyethylene terephthalate film.
  • the carrier film preferably has a thickness of 5.5 to 12 ⁇ m.
  • the decor layer arrangement used according to the invention by a arrangement known per se from hot stamping foils, the expedient - based on the carrier film - one Protective lacquer layer, at least one decoratively designed Lacquer layer and an adhesive layer comprises.
  • Decorative layer arrangement are gem for the transfer film.
  • the invention a variety of design options created.
  • the decorative layer arrangement by using different colors of the lacquer layer include certain patterns, logos or the like.
  • the decorative layer arrangement can also be optically have effective structure, in which case the Decor layer arrangement metallized at least in some areas should be. Details regarding the training of the Decorative layer arrangement are not described here because they are generally made from hot stamping foils, in particular in the security sector.
  • the transfer film according to the embodiment includes a carrier film 1, which is, for example, a Polyethylene terephthalate film with a thickness of 3.5-19 ⁇ m, preferably a thickness of 5.7-12 ⁇ m.
  • This carrier film is on one side with a Provide sliding layer 2, which is to prevent the Carrier film sticks to the print head or embossing stamp.
  • the Carrier film 1 On the opposite side of the sliding layer is the Carrier film 1 in the embodiment shown with a continuous, transparent protective lacquer layer 3, which, however, can be dispensed with if necessary. It would also be conceivable between protective lacquer layer 3 and Carrier film 1 is known from hot stamping foils Provide release layer, which are, however, dispensed with can, if a material for the protective lacquer layer 3 Lacquer is used, which differs slightly from Carrier film 1 releases.
  • the protective lacquer layer 3 in turn contributes to the shown Embodiment three different elements, namely a decorative layer arrangement designated overall by 4, a thermal transfer layer 5 and registration marks 5.
  • the fields can also do so be arranged so that they abut each other directly.
  • the decorative layer arrangement 4 can be made from hot stamping foils be designed in a variety of ways known.
  • the lacquer layers 7a and 7b only have different colors to make them decorative To achieve effects.
  • Lacquer layers 7a and 7b with different To provide light transmission.
  • the interface 9 between the layers of paint 7a, 7b and the protective lacquer layer 3 with a spatial Structure to provide certain optical To achieve effects, such as light diffraction, etc. to reach.
  • the interface 9 expediently be provided with a metallization in order to to let optical effects appear clearly.
  • thermo transfer layer 5 gives the possibility of individualization.
  • decor images, company logos or other security features in the form of a Decorative layer arrangement on ID cards, labels, Securities etc. are attached, which then each individually using the thermal transfer layer with a individualizing labeling.
  • transfer film acc. of the invention generally one after the other in one Hot stamping unit the decorative layer arrangement 4 and on the other hand in a thermal printer unit individualized labeling using the Thermal transfer layer 5 applied.
  • the decorative layer arrangement 4 in the hot stamping process either overall, but also only in some areas on the Substrate are transferred, expediently such the procedure is that the decorative layer arrangement 4 already is accordingly graphically designed to total to be able to be transferred.
  • the exact orientation of the Decorative layer arrangement 4 on the one hand and the one for generation serving the individualizing marking Thermal transfer layer 5 on the other hand takes place with the help of Registration marks 6, which are usually not on the substrate be transferred with.
  • substrates are used, for example plastic cards made of PVC, PC, PET etc. Also plastic or paper labels or Securities can be decorated accordingly.
