Definitions

  • Security labels for marking goods are well known and are used in a wide variety of areas of technology. For example, components supplied to the automotive industry are provided with such security labels.
  • Black aluminum oxide is particularly suitable for such a layer, which has a black metallic color due to a substoichiometric oxygen content of the aluminum oxide.
  • laser-writable layer is to be understood as such a black aluminum oxide layer (sometimes also referred to as "black metallization"), unless otherwise stated.
  • a particularly efficient production of films having such a black aluminum oxide layer is known from EP 1522606 B1 known.
  • Corresponding layers can be "written" by means of laser action, whereby the energy input makes the aluminum oxide layer transparent along the path of the laser beam.
  • the processes responsible for this, which take place due to the energy input, can include evaporation, oxidation, ablation and the like, as can be seen from the US 5766827 A is known.
  • an opaque, optically contrasting layer can be arranged below the aluminum oxide layer.
  • a generally desirable property of security labels is the so-called document authenticity, which in particular includes the property that manipulation or even removal of the security label is not possible without leaving traces.
  • so-called "void labels” are known from the state of the art, which are used to indicate attempts to tamper with objects and packaging, cf. for example the EP 2603910 B1 or the EP 2603911 B1 .
  • void labels With these void labels, a layer structure with at least one release lacquer layer ensures that a previously invisible or invisible security feature appears on the label surface as soon as the void label is removed from the respective substrate.
  • the security feature are usually lettering, images, patterns or the like.
  • a laser-writable film structure which, in order to ensure security against tampering, has layers with continuous punching lines which cause the said layers to be destroyed in the event of tampering.
  • a label is known in which a second layer of varnish is applied to a thicker (first) layer of varnish underneath, with this thicker layer of varnish being applied as a carrier layer on an adhesive layer.
  • Discrete inclusions made of a polymer are printed on the adhesive layer, whereby the inclusions contain detectable additives.
  • the inclusions are imprinted on the layers above, so that the surface of the label has optically visible and tactile impressions of the inclusions.
  • the label is removed by force, the inclusions, together with the detectable additives, remain partially in the adhesive, which is why an expert must determine the missing inclusions or the missing detectable additives can be used to determine whether such a label has already been removed and thus re-glued.
  • a label is known whose structure includes an upper visible side and an interrupted separating layer that is printed on the underside of the visible side, as well as an adhesive layer that ensures that there is a strong adhesive force between the visible side and an underlying contrast layer.
  • the label also has a pressure-sensitive adhesive layer on its underside, with which the label is stuck to a substrate.
  • the upper visible side detaches from the separating layer in the area of the separating layer, so that indirect contact between the visible side and the contrasting layer is lost in the area of the separating layer.
  • the adhesive layer is glued to the underside of the visible side without an intervening separating layer, the indirect connection between the visible side and the contrasting layer is maintained by means of the adhesive layer. In this way, when the label is removed from a substrate, tamper-proof symbols, figures and the like can be created.
  • one or more further layers, in particular protective layers are arranged above or, as seen in the first direction, in front of the at least one transparent protective layer.
  • the at least one transparent protective layer does not have to be arranged directly in front of the laser-writable layer, i.e. one or more further layers can be arranged between the at least one transparent protective layer and the laser-writable layer.
  • the laser-writable layer appears dark, in particular black.
  • the contrast layer serves to generate an optical contrast of the, in particular transparent, inscription in the laser-writable layer.
  • the contrast layer can be white.
  • the contrast layer does not have to be arranged directly behind the laser-writable layer, i.e. one or more further layers can be arranged between the laser-writable layer and the contrast layer, for example a laminating adhesive layer.
  • the at least one fracture layer can be formed by the laser-writable layer and/or by the at least one transparent protective layer and/or by the contrast layer and/or by at least one further layer. If the laser-writable layer forms the fracture layer, the aluminum oxide of the laser-writable layer can be applied to a plastic film of the laser-writable layer, which plastic film is brittle or has the desired brittle properties.
  • the said destruction of the at least one fracture layer and the laser-writable layer, and optionally one or more intermediate layers, comprises breaking or tearing.
  • the fracture layer Due to its brittleness, the fracture layer is reliably destroyed if the security label is manipulated or removed. According to the above, the laser-writable layer, including any intervening layers, is also destroyed if the fracture layer is destroyed. Document authenticity is therefore ensured.
  • a characteristic value for the brittleness of a material is its elongation at break.
  • the latter is typically in the range of 10 ⁇ m to 100 ⁇ m for plastic films with thicknesses of 10 ⁇ m to 100 ⁇ m, in particular 12 ⁇ m to 100 ⁇ m, as is commonly used for security labels. of approximately 100% or even significantly more than 100%.
  • a 50 ⁇ m thick film made of polyethylene terephthalate (PET) has an elongation at break of 190% in the machine direction and 120% across it. If the elongation at break of the plastic film is more than 60%, in particular more than 80%, there is in any case insufficient brittleness.
  • the security label according to the invention is designed, as mentioned, for the brittle plastic film of at least one breaking layer to have an elongation at break of less than 20%, preferably less than 15%, particularly preferably less than 10%.
  • elongation at break values apply to the plastic film as such, i.e. considered on its own - without the entire structure of the security label with the other layers.
  • the brittle plastic film of the at least one fracture layer is an acrylate film or a polyvinyl chloride film (PVC film) or a polyurethane film (PU film). Said films are sufficiently brittle per se. Additional embrittlement, for example through targeted UV irradiation, is not necessary. Furthermore, no significant additional embrittlement of the plastic films used usually occurs during the manufacturing process.
  • the contrast layer on the security label is designed as a fracture layer. This allows extremely compact structures to be created with a minimal number of layers, whereby the contrast layer can be arranged directly or not directly behind the laser-writable layer when viewed in the first direction.
  • the security label according to the invention is provided with at least one further layer between the laser-writable layer and the contrast layer, wherein the at least one further layer comprises at least one partial release lacquer layer.
  • the at least one further layer can comprise further layers in addition to the partial release lacquer layer, e.g. a layer of laminating adhesive.
  • the partial release lacquer layer is not completely continuous, so that certain symbols or characters can be seen when the security label is removed. to further increase the authenticity of the document.
  • the partial release coating provides a different level of adhesion between the layers arranged in front of and behind the release coating compared to the adhesion of these layers without an intermediate release coating, in order to cause certain shaped areas to detach when the security label is removed or manipulated and to make the symbols mentioned visible.
  • a particularly preferred embodiment of the security label according to the invention provides that at least one further layer is arranged between the protective layer and the laser-writable layer, wherein the at least one further layer comprises at least a partial release lacquer layer.
  • the at least one further layer can also comprise further layers in addition to the partial release lacquer layer, e.g. a layer of laminating adhesive.
  • the partial release lacquer layer is not completely continuous, so that certain symbols or characters are created when the security label is removed in order to (even) further increase the authenticity of the document.
  • the at least one partial release lacquer layer has the shape of one or more letters, one or more characters, one or more symbols, one or more lines, one or more guilloches, one or more numbers or one or more lettering.
  • the corresponding shape(s) will be formed when the security label is removed due to the local different detachment of the layers adjacent to the partial release coating layer.
  • the at least one protective layer comprises a layer of a UV transfer varnish. This represents a particularly favorable solution in terms of process technology for producing the at least one protective layer.
  • a particularly transparent layer made of plastic, in particular PET, or a plastic film, in particular PET film can initially be provided, which, viewed in the first direction, is arranged immediately in front of the layer of UV transfer varnish and is subsequently removed again (by peeling off) - typically already before the security label is applied.
  • the at least one protective layer comprises a layer of a plastic film, in particular polyethylene terephthalate film (PET film).
  • PET film polyethylene terephthalate film
  • the at least one protective layer consists of at least one layer of plastic film, in particular PET film, or is completely formed by it.
  • a protective lacquer layer is applied as the "top" or first layer, which can be arranged above the said at least one transparent protective layer.
  • This protective lacquer layer protects the surface of the Security labels against abrasion and can in particular be slightly matt. The latter reduces the reflection of the surface and can therefore prove advantageous if, for example, a barcode written into the laser-writable layer is to be read by a scanner.
  • the at least one protective layer comprises a layer of a protective varnish or printing varnish.
  • a layer of a printable adhesion promoter can be provided above the at least one transparent protective layer - and below the protective lacquer layer mentioned. This proves to be advantageous, for example, if the security label is initially delivered to a customer with the layer of adhesion promoter as the top layer, who can then print a logo, for example, on the adhesion promoter layer and then apply the protective lacquer layer mentioned, in particular a matt one.
  • the at least one protective layer comprises at least one fracture layer.
  • the fracture layer is preferably arranged directly in front of the laser-writable layer when viewed in the first direction, so that the direct adhesion of the fracture layer to the laser-writable layer results in the highest possible security against the destruction of the laser-writable layer if the fracture layer is destroyed.
  • the contrast layer does not have to be located directly behind the laser-writable layer when viewed in the first direction.
  • a preferred embodiment of the security label according to the invention provides that the contrast layer is arranged directly behind the laser-writable layer when viewed in the first direction. This guarantees optimal readability of what is written in the laser-writable layer in terms of contrast.
  • FIGS. 1 to 5 show, in schematic sectional views, embodiments of a security label 1 with several layers, which is a "laser-writable security label", ie a security label 1 comprising a laser-writable layer 2 with black aluminum oxide.
  • the laser-writable layer 2 has a top side 4 and a bottom side 5, which are arranged opposite one another and point away from one another. Viewed in a first direction 6, the top side 4 is arranged in front of the bottom side, or the first direction 6 points from the top side 4 to the bottom side 5.
  • a transparent protective layer 3 is arranged directly in front of the laser-writable layer 2 in order to protect the laser-writable layer 2 from external influences.
  • a contrast layer 7, eg white, is arranged behind the laser-writable layer 2 as seen in the first direction 6, whereby the contrast layer 7 does not have to immediately follow the laser-writable layer 2. If, as described at the beginning, the laser-writable layer 2 is written on with a laser, the laser-writable layer 2 becomes transparent along the path of the laser beam, whereby the contrast layer 7 makes the said path particularly clearly visible.
  • the contrast layer 7 can be applied with a self-adhesive layer 15 on a substrate 9, wherein the substrate 9 is formed, for example, by a product whose authenticity is to be guaranteed by means of the security label 1.
  • At least one of the several layers is designed as a fracture layer 8 made of a brittle plastic film in order to cause destruction of the at least one fracture layer 8 and the laser-writable layer 2, and optionally one or more intermediate layers, in the event of manipulation or detachment of the security label 1 stuck to a substrate 9.
  • the brittle plastic film of the at least one fracture layer 8 can have an elongation at break of less than 20%, preferably less than 15%, particularly preferably less than 10%.

  • the self-adhesive layer 15 with which the security label 1 is applied to the substrate 9.
  • the fracture layer 8 breaks and destroys the arranged layers, i.e. those layers which are arranged in front of the fracture layer 8 as seen in the first direction 6, and thus in particular also the laser-writable layer 2.
  • the partial release lacquer layer 10 is not completely continuous, so that certain symbols or characters are also created when the security label 1 is removed in order to further increase the authenticity of the document.
  • the partial release lacquer layer 10 provides a different adhesion between layers arranged in front of and behind the release lacquer layer 10 - i.e. in particular between the laser-writable layer 2 and the white acrylate film 16 or the laminating adhesive layer 11 - compared to the adhesion of these layers without an intermediate release lacquer layer 10, in order to cause a detachment of certain shaped areas when the security label 1 is removed or manipulated and to make the symbols mentioned visible.
  • the partial release lacquer layer 10 can for this purpose in particular have the shape of one or more letters, one or more characters, one or more symbols, one or more lines, one or more guilloches, one or more numbers or one or more lettering.
  • Fig. 2 shows a second embodiment of the security label 1 according to the invention with a particularly compact structure that requires a minimum number of layers.
  • the transparent protective layer 3 is again provided as the first layer, which in this case is formed by a transparent acrylate film 17 and thus also simultaneously forms the fracture layer 8.
  • the laser-writable layer 2 is arranged directly behind the protective layer 3, so that if the fracture layer 8 is destroyed, the laser-writable layer 2 is also reliably destroyed.
  • the laser-writable layer 2 is in turn arranged directly on the contrast layer 7, wherein the contrast layer 7 is formed by a white lacquer layer 18. Behind the contrast layer 7 is arranged the self-adhesive layer 15, with which the security label 1 is applied or glued to the substrate 9.
  • Fig. 3 shows a third embodiment of the security label 1 according to the invention, wherein the fracture layer 8 is again formed by the contrast layer 7, in that the contrast layer 7 is formed as a white acrylate film 16.
  • the transparent protective layer 3 comprises not only the transparent PET film 13, but also a transparent UV transfer lacquer layer 19, which represents a particularly favorable solution in terms of process technology for producing the at least one protective layer 3.
  • the transparent PET film 13 arranged in the first direction 6 immediately in front of the UV transfer lacquer layer 19 is usually removed again before the security label 1 is applied to the substrate 9 (by peeling it off), which can happen in different process steps. Accordingly, in Fig. 3 the security label 1 is also not shown applied to the substrate 9.
  • the following sequence of layers arranged one behind the other results: the transparent PET film 13; the UV transfer varnish layer 19; the laser-writable layer 2; the (transparent) laminating adhesive layer 11; the white acrylate film 16; and the self-adhesive layer 15, with which the security label 1 can be applied to the substrate 9. If the fracture layer 8 is destroyed, all layers arranged above the fracture layer 8 - and thus in particular the laser-writable layer 2 - of the security label 1 applied to the substrate 9 are also reliably destroyed.
  • Fig. 4 shows a fourth embodiment of the security label 1 according to the invention, wherein the fracture layer 8 is again formed by the contrast layer 7 and a particularly compact structure can be achieved with a minimal number of layers.
  • the transparent protective layer 3 is formed in this case by a protective lacquer layer 20, which not only protects the surface of the security label 1 from abrasion, but can in particular be matt in order to prevent reflections and thus facilitate the readability, in particular by machine, of the information (symbols, writing, etc.) encoded in the laser-writable layer 2.
  • Seen in the first direction 6, the laser-writable layer 2 is arranged directly behind the protective lacquer layer 20 and directly behind this is the contrast layer 7 or fracture layer 8 formed by the white acrylate film 16.
