  • the card body is specifically a card body of a card-shaped data carrier.
  • the card body can essentially provide a credit card to itself.
  • electrical or electronic components are typically introduced into the card body. This can be done in such a way that the method step of providing at least one film is carried out iteratively, such that a film stack arises in which the electronic components are inserted. After a hot lamination of the plurality of films, the multilayer card body thus arises.
  • the metal oxide itself or its quantity and granularity can be used, and the laser can be adjusted accordingly.
  • the metal oxide per se is generally suitable for altering the underlying carrier of the film layer so that it is precisely this film that is more or less susceptible to laser engraving. This means that depending on the quantity and granularity or the selection of the metal oxide, the laser intensity can be tuned to this. If the material underlying the film is highly absorbent, then the laser beam can also be set to be weaker. On the other hand, if the underlying carrier material is designed to be only slightly absorbent by means of the additive, then a stronger laser beam may be necessary.
  • the personalization of the provided film can be done at a stage where the film has not yet been laminated together with other films, but can also be done using the finished card body.
  • a laser engraving is generally the introduction of a point high energy such that at least one material of the film carbonized. This can be done in such a way that the additive per se carbonizes by means of heat and turns black, or else that the additive absorbs heat and carbonizes a material surrounding the additive by means of heat radiation. This results in a black or at least grayish color. Both the resulting image and the process of lasing are referred to as laser engraving.
  • the optimized personalization is caused in such a way that by means of the metal oxide used, the film or the card body can be personalized in the desired manner.

  • a further security element is realized in a particularly advantageous manner.
  • metal oxides are particularly suitable as a laser additive, and in particular that they are to be selected such that they do not scatter but absorb laser light. It may thus be possible for the person skilled in the art generally to provide metal oxides, but not to arrange or select them in such an advantageous manner that they improve laser engraving.
  • metal oxides are known in the provision of further components within a chip card, these other components, such as an antenna, are not provided by means of a laser engraving. In this case, therefore, the at least one metal oxide is selected such that it cooperates particularly advantageously with personalization.
  • personalization, in particular lasering is thus optimized by means of the introduced metal oxide.
  • An optimization does not necessarily have to be the provision of a particularly fine laser engraving, but rather any quality of the laser engraving can be brought about by means of the metal oxides, wherein it is merely necessary to ensure that the desired quality is actually verifiable in the end product.
  • a security feature is provided, which in addition can be designed aesthetically particularly appealing.
  • the metal oxide is substantially nanoscale. This has the advantage that the metal oxide can be provided in such a fine granular form that it brings about the desired technical effect, namely that a high-contrast coloring sets in the finished end product. In this case, it has been found according to the invention that such a granularity enables a particularly advantageous engraving. According to the prior art, it is only known to use metal oxides, for example in conductive pastes in coarser granularity.
  • the metal oxide is present in a size range between 1 and 100 nm.
  • This has the advantage that a particularly advantageous size range is provided, and that, for example, different particle sizes can also be used.
  • a first metal oxide for example, in a particle size of 10 nm and to provide a particle size of 90 nm according to a second metal oxide.
  • such an order of magnitude has a particularly advantageous effect, particularly in the area of the card bodies or credit cards. This is the case because individual layers in the micrometer range are thick and thus the proposed size range causes a particularly attractive laser engraving even in such a thin layer.
  • the metal oxide is provided as a laser additive for optimized personalization.
  • This has the advantage that the personalization can be carried out depending on the laser additive, and in particular that the laser engraving can be adjusted so that the properties of the metal oxide used can be taken into account.
  • overall properties of the laser can take into account the choice of metal oxide, the amount and / or the granularity.
  • a particularly optimized personalization process is achieved without further work steps would have to be changed in this case.
  • the metal oxide is TiN, tungsten oxide compound, molybdenum oxide compound, copper oxide compound, copper phosphate oxide or copper oxide compound in front.

The chains can be arranged differently depending on the polymer, for example These may form an amorphous or partially crystalline structure. In this case, a so-called semi-crystalline polymer can arise.
  • the plastic matrix is introduced in such a way that the film is stabilized.
  • transparent outer layers are attached to the card body. This has the advantage that the resulting pattern or the resulting laser engraving is visible from outside and is still protected.

Furthermore, it is also possible to provide a transparent laser-doped outer layer itself. Furthermore, a transparent laser-doped overlay foil can be arranged above it.
  • the card body is made of a plurality of provided films by lamination.
  • This has the advantage that several layers can be provided, which are then laminated to a card body.
  • it is possible to match the lamination process as a function of the introduced metal oxides, since individual layers comprising the metal oxides behave differently under the influence of temperature than untreated layers.
  • the heat exposure during lamination can be regulated depending on the introduced metal oxides.
  • At least one opaque film is provided.
  • This has the advantage that such an opaque film can be extruded, for example, and can be made from PLA, and furthermore can have a thin, transparent, laser-doped outer layer. This is very efficient with respect to laser engraving, especially in combination with a transparent laser-doped overlay film.
  • At least one layer provided is laser doped. This has the advantage that even several layers can be laser doped, and so a laser engraving is possible through several layers away. In this case, it is possible to introduce the laser engraving into the individual foils per se, without these being already laminated to form a foil stack.

  • Plastics do not absorb laser radiation in the range of near ultraviolet to near infrared light. An implementation of the laser energy in (melting) heat is therefore only possible if the polymer was "laser-sensitized" by the addition of an additive. Without a laser additive, plastics can therefore only be processed in far-ultraviolet light, eg with excimer lasers and in far-infrared light, eg with CO 2 lasers.
  • Cards made from renewable raw materials, in particular PLA cards are currently produced from semi-crystalline or combinations of amorphous and semi-crystalline materials. This is necessary in order to be able to meet the temperature stability requirements (crystalline) and at the same time be able to process the films (laminating, printing, etc.).

Temperature and material throughput are relevant for the process, so that the material or the film according to the invention does not thermally degrade. By thermally degrading the term, it is meant that if a molten material remains in the extruder for too long, then the molecular chains are shortened, thus degrading the material properties.
  • the film according to the invention should have a residual moisture of less than 20 ppm.
  • the roll temperatures of the chill-roll and calender roll mill affect the crystallinity of the film. This means that the higher the respective roll temperature, the higher the crystallinity of the film.

  • the laser becomes poorer and the film becomes cloudier.
  • the dispersibility in this case depends on the melt mass flow rate of the PC and the ratio of PC to PLA in the masterbatch. Nevertheless, an excessive addition of the masterbatch can lead to a clouding of the transparency.
