Definitions
- the invention relates to transfer films for applying a decorative layer arrangement formed by at least one lacquer layer and a heat-activatable adhesive layer to a substrate.
- security elements are very often used, which are formed by a decorative layer arrangement which comprises, for example, diffraction-optical or holographically effective structures.
- certain graphic designs can also be provided as security elements.
- the security elements are very often attached by means of a transfer film, for example a hot stamping film, the decorative layer arrangement forming the security element usually comprising at least one lacquer layer and one layer of a heat-activatable adhesive which connects the actual one
- Lacquer layer representing security element or arrangement of lacquer layers with the substrate for example a bank note, a check, an identification paper or a credit card.
- the security element is automatically transferred to the document.
- transfer foils mostly so-called hot stamping foils
- the decorative layer arrangements of hot stamping foils have only a very small thickness. They essentially consist of only a few layers of paint. This small thickness of the security elements has the advantage that if the security elements are only arranged in a certain area of the document, there are still no fundamental differences in thickness in the document. Such differences in thickness could make stacking problematic.
- Another advantage of using decorative layer arrangements consisting of several layers of lacquer as security elements is that such layer arrangements are not mechanically very stable. Therefore, if an attempt is made to remove a security element from the document, it can be assumed with almost certainty that the security element from the various layers of lacquer will be destroyed, so that the forgery or the attempt to forge it can be easily identified.
- hot stamping foils for attaching security elements to documents has the disadvantage that a corresponding mechanical effort must always be carried out because the application of hot stamping foil decorative layers as security elements on substrates is practically impossible by hand because of the very small thickness of the Decorative layer arrangement of a hot stamping foil.
- a security element could be individualized before being applied to a document. This option is particularly worthwhile for personal documents.
- a security element could then be used which, prior to being applied to the document, was personalized with personal data of the holder of the document, for example a photo, name or birthday etc.
- this possibility is ruled out if security elements are transferred to a document by means of a known hot stamping foil, and above all because the individual printing of security elements on the Hot stamping foils are always present in very large numbers, due to the effort involved, is then eliminated when only a few, appropriately individualized security elements are required. For example, only very few security elements with personal data are required for identity cards, passports, etc. Such an element is often sufficient, which then becomes part of the identity card or passport.
- the invention is based on the object of creating a transfer film, by means of which a security or decorative element can be transferred, the structure of which basically corresponds to the decorative layer arrangement of a hot stamping foil known per se, the application of the decorative layer arrangement to the substrate, for example a document , should also be possible without extensive mechanical equipment.
- a transfer film of the type mentioned which comprises a base film which is connected by means of a permanent adhesive to one surface of a carrier film, on the other surface of which the decorative layer arrangement is arranged, which can be detached from the carrier film under the action of heat and has on its side facing away from the carrier film the heat-activatable adhesive layer serving for connection to the substrate.
- the transfer film according to the invention thus differs from known hot stamping films in that, in addition to the carrier film which is provided in known hot stamping films to stabilize the decorative layer arrangement, there is an additional base film which is connected to the carrier film by means of a permanent adhesive.
- the carrier film and base film are usually connected after the actual hot stamping film has been completed.
- a transfer film is thus obtained which has a relatively high stability, because instead of the relatively thin carrier film which has hitherto been customary in hot stamping films, a combination of base film and carrier film is present which has the necessary stability to the transfer film as well without being able to handle complex machines properly. In use, the user places such a transfer film on the substrate with the side on which the decorative layer arrangement with the adhesive is provided.
- the decorative layer arrangement is then connected to the substrate by appropriate action of pressure and heat, and then the carrier film is pulled off together with the base film from the decorative layer arrangement, which remains on the substrate.
- a transfer film according to the invention there is thus the possibility of transferring to the substrate, for example a document, a very thin decorative layer arrangement which until now could only be applied using the hot stamping film technique.
- the handling of the transfer film is greatly simplified because of the stability of the combination of the base film and the carrier film.
- the decorative layer arrangement can be designed in the manner known from hot stamping films. In particular, it is not necessary to ensure a corresponding stability of the decorative layer arrangement in itself, because this decorative layer arrangement is sufficiently stabilized during manufacture due to the presence of the carrier film.
- a transfer film which has a significantly wider field of application than known hot stamping foils, in particular can also be processed safely and reliably using very simple apparatus.
- the transfer film according to the invention with regard to the decorative layer arrangement, there are all the design options known hitherto from hot stamping foils.
- the base film is formed by a paper web which is siliconized on its surface facing away from the carrier film and which has its siliconized surface releasably adhering to a carrier film, for example a carrier paper.
- a carrier film for example a carrier paper.
- several small security elements can be arranged on a common sheet, namely the carrier film.
- a security element consisting of base film, carrier film and decorative layer arrangement is then detached from the carrier film and transferred accordingly to the substrate provided.
- This transfer of individual elements can advantageously be facilitated in that the base film with the carrier film and the decorative layer arrangement is subdivided into a plurality of label-like individual elements, with several such individual elements being arranged on a carrier film web such that they can be pulled off.
- the subdivision is expediently such that the individual elements are formed by punching or perforating the base film, carrier film and decorative layer arrangement along their intended peripheral edges, the carrier film not being divided.
- a particularly advantageous embodiment of the transfer film according to the invention is designed such that the decorative layer arrangement is transparent and the adhesive layer used to fix the decorative layer arrangement on the substrate can be printed by means of a printer, for example a laser or thermal printer.
- a printer for example a laser or thermal printer.
- a corresponding individualization can take place by printing on the adhesive layer. It is e.g. conceivable, the personal data containing page of a passport using a transmission foi acc. secure the invention, the basic information already in the factory production of the transfer film in a corresponding
- Printing process for example between individual layers of the decorative layer arrangement provided over the entire surface, while the personal data, for example last name, first name, address, date of birth and picture of the passport holder, are then printed on the adhesive layer by means of a suitable printer before the transfer film is used.
- the transfer film with the printed adhesive layer is then placed on the substrate and attached to the substrate by heat and possibly pressure.
- This embodiment has the advantage that the individualizing information is covered by the decorative layer arrangement of the transfer film, ie a change is not possible without damaging the decorative layer arrangement at the same time. If one tries to pull the decorative layer arrangement away from the substrate in order to change the individualizing data, the decorative layer arrangement is expected to be destroyed become.
- the individualizing data can also be found on the substrate, because under the usual processing conditions of the transfer film according to the invention, at least a certain proportion of the printing ink present on the adhesive layer also binds directly to the substrate.
- the decorative layer arrangement has at least one repeating lacquer layer provided on one surface with a diffraction-optical and / or holographically effective structure.
- diffraction-optical or holographically effective structures are generally known per se from security elements formed by hot stamping foil decorative layer arrangements and therefore do not need to be explained in more detail.
- the diffraction-optical or holographically effective structure is covered by means of a reflective layer, generally a vapor-deposited metal layer, and is therefore more visible in incident light.
- the diffraction-optical and / or holographically effective structure carries a transparent layer of a material whose refractive index is significantly higher than that of the transparent repeating lacquer layer. With such a design, sufficient visibility of the optically effective structure is obtained.
- the decorative layer arrangement remains transparent, so that the substrate and any markings provided between the substrate and the decorative layer arrangement, e.g. a print on the adhesive layer of the
- Decorative layer arrangement can recognize.
- the material layer which increases the visibility of the optically active structure is expediently produced by, for example, vapor-depositing a layer of ZnS, TiO 2 , SiO or a material which is similar in terms of refraction.
- the heat-activatable adhesive layer which is used to fix it to the substrate, is formed by two adhesive layers, between which a marking produced in a printing process is arranged is
- the marking can advantageously be formed by printing inks that are only recognizable when illuminated with light of predetermined wavelength ranges. If one speaks of two "adhesive layers", it is not absolutely necessary that the two adhesive layers are composed and constructed in the same way. Rather, it is thought in particular of the case where the first layer of adhesive - as seen from the carrier film - is an adhesion promoter layer which ensures that the adhesion to the vapor-deposited layer which improves the visibility of the diffractive structure is particularly good. It would also be conceivable for only one layer of adhesive to be present, in which case the marking produced in the printing process would then have to be present directly on the layer which improves the visibility of the structure.
- the layer sequence of the decorative layer arrangement will be varied in accordance with the requirements of the user, a hot stamping foil with corresponding layers usually being produced first and this hot stamping foil then being laminated together with the base foil.
- an adhesive must be used to connect the base film of the hot stamping foil to the base foil, which does not reduce its adhesive strength at the temperatures used for the application of the decorative layer arrangement and ensures that the base foil and base film are securely held together.
- a particularly useful embodiment of a transfer film acc. The invention is characterized in that it comprises the following constituent parts or layers:
- Carrier film has successive layers on its free surface - a release layer - only available if necessary -
- a transparent repeating lacquer layer on its surface facing away from the carrier film, which has the diffraction-optical and / or holographically effective structure, a layer of a material that is highly refractive in comparison to the replication lacquer layer, at least partially covering the structure,
- the layer of highly refractive material and the heat-activated adhesive layer (s) are transparent and the adhesive layer forming the surface of the transfer film facing away from the carrier film is formed by a printable material by means of a printer.
- the transfer film of the training explained above fulfills the requirements set out above in an excellent manner. It offers the possibility of attaching a comparatively thin decorative layer arrangement, previously only transferable by means of hot stamping foil, to a substrate without great mechanical expenditure. At the same time, the transfer film according to the invention is easy to handle and it is easily possible to individually print various security elements formed by means of a transfer film according to the invention.
- Fig. 1 shows a portion of an arc with several of one
- FIG. 2 is a single, according to the arrangement.
- Fig. 3 shows a security element acc. Figure 2 after application to a substrate and after detachment of the decorative layer arrangement from the remaining layers.
- the transfer film according to FIG. 1 comprises - in the drawing from top to bottom - a carrier film 1 to which a base film 3 is relatively easily detachably fastened by means of a suitable adhesive 2.
- the base film 3 is using a
- the hot stamping film 6 consists on the one hand of the carrier film 5, and on the other hand of the decorative layer arrangement designated overall by 7, which can be detached from the carrier film 5 in the manner which is customary per se from the processing of hot stamping films and can be transferred to a substrate 8 shown in FIG. 3 is.
- the following layers are arranged on the side of the carrier film remote from the base film 3
- a release layer 9 a protective lacquer layer 10
- a repeating lacquer layer 11 which, as indicated schematically in the drawing, is to be provided with a structure 12 having an optical diffraction or holographic effect
- the different layers of the transfer film are subdivided by punchings or perforations 16, in order in this way to form, for example, label-like individual elements 17.
- the punchings or perforations 16 do not, however, grasp the carrier film 1.
- markings are present in the area of the interface 18 between the adhesion promoter or first adhesive layer 14 and the second adhesive layer 15.
- These markings are preferably applied in a printing process and expediently consist of a lacquer or a printing ink which can only be used when illuminated with light of a special wavelength, e.g. is visible when illuminated with UV light.
- a prerequisite for the visibility of the markings 19 is, of course, that the different layers 10, 11, 13, 14 and 15 of the decorative layer arrangement 7 are correspondingly transparent.
- FIG. 1 shows a transfer film, such as can be commercially available and which the respective consumer uses to apply the individual label-like elements 17 to a substrate
- FIG. 2 only shows a label-like individual element 17, in which - in addition to 1 of the embodiment of FIG. 1, the second adhesive layer 15 is provided with individualizing information, for example with information about the person of an identity card holder, including images.
- the adhesive layer 15, as indicated at 20, is printed accordingly. The print can be done with usual
- Printing devices for example by means of thermal transfer printing, laser printing, etc. It can be assumed that, despite the partial printing at 20, the adhesive layer 15 adheres sufficiently firmly to the substrate, provided that only the thickness of the Adhesive layer 15 is large enough and there is sufficient area in which non-printed adhesive directly adjoins the surface 21 of the substrate 8, for example an identification card or the like. If 20 small particles are used to generate the print, an almost full-surface printing can even take place, since the adhesive of the layer 15 can then pass between the individual particles accordingly.
- Adhesive layer 15 attached. This can easily be done, for example, by using a paper web in standard format as the carrier film, which can then be inserted into commercially available printers which produce the desired print (20) on the free surface of the adhesive layer 15.
- At least one label-like individual element 17 is then removed from the carrier film 1, e.g. a backing paper.
- the carrier film e.g. a backing paper.
- silicone paper is used as the base film, which is siliconized on the surface 22 facing the adhesive layer 2, while the other surface connected to the carrier film 5 has no coating and therefore adheres well.
- the correspondingly printed individual element 17 detached from the carrier film 1 is then placed on a substrate and, preferably at a correspondingly elevated temperature of approximately 130 ° C., pressed against the surface 21 of the substrate.
- the adhesive layer 15 and, as a result, the entire decorative layer arrangement 7 firmly connects to the surface 21 of the substrate 8.
- the release layer 9 softens, so that it is easily possible to remove the carrier film 5 and the base film 3 firmly connected to it by means of the permanent adhesive layer 4 subtract the decorative layer arrangement.
- FIG. 3 a representation was chosen in which the decorative layer arrangement 7 covers only a region of the surface 21 of the substrate 8.
- the size of the label-like individual elements 17 such that they match the size of the substrate, that is to say, for example, the size of one side of a passport or the size of an identity card.
- the individual layers can, for example, be selected or composed as follows:
- Carrier film 1 A carrier paper is preferably used as the carrier film, paper with a weight per unit area of about 35 to 150 g / m 2 advantageously being used.
- the base film 3 is a reinforcement layer which is also known per se from labels.
- a plastic film can be used.
- the permanent adhesive 4 has the task of ensuring that base film 3 and carrier film 5 remain firmly connected to one another even when heat is used to transfer the transfer film to the substrate. These conditions are generally met by common, permanently adhering acrylic dispersion adhesives.
- carrier films used for hot stamping foils are used here, whereby plastic films with a very smooth surface are usefully used have in order not to impair the transparency of the decorative layer arrangement 7 by surface irregularities.
- polyester films with a thickness of around 20 ⁇ m are used as the carrier film, although in the present case thinner carrier films 5 can also be used, since the carrier film 5 is reinforced by the base film 3 during handling.
- the release layer 9 is generally applied over the entire area in a layer thickness of approximately 0.01 to 0.2 ⁇ m.
- it can be composed as follows:
- the protective lacquer layer 10 is also generally applied over the entire surface, specifically in a layer thickness of 0.5 to 5.0 ⁇ m, preferably of 1 to 2 ⁇ m.
- the protective lacquer layer 10 can be composed as follows:
- the repeating lacquer layer 11 can be applied over the entire area, but also only in regions, specifically if, for example, it should be provided that the holographically or diffraction-optically effective structure 12 should only be provided in regions.
- the layer thickness of the repeating lacquer layer 11 is 0.05-1.5 ⁇ m. It can have the following composition: Cyclohexanone 200 g
- Methyl methacrylate (d 1.17 g / m 3 , mp> 130 ° C.) 12 g
- the structure 12 can be a generally known structure which is conventional for so-called OVDs and has an optical diffraction or holographic effect, for example a grating structure, the optical properties of the structure 12 being determined by the corresponding structure parameters, for example grating frequency, grating depth, grating inclination, etc. ,
- the structure 12 is generally introduced into the replication lacquer layer 11 in a replication process during the production of the hot stamping foil 6.
- the task of the highly reflective layer 13 is to improve the visibility of the diffraction-optically or holographically effective structure 12, whereby, as can be seen from a view of FIG. 3, it must be ensured at the same time that the viewer can see through the layer 13 to the markings 19 and the Recognize pressure 20.
- This task can be performed, for example, by a vapor-deposited, high-index layer with a thickness of 10 to 500 nm, with metal oxides, metal sulfides, titanium dioxide, etc. being able to perform this task.
- Adhesive layers 14 and 15 are Adhesive layers 14 and 15
- the two layers 14 and 15 from the same, transparent material.
- the layer 14 merely as an adhesion promoter layer between the adhesive layer 15 and the coating 13 of the structure 12.
- the adhesive layers can be composed as follows:
- Vinyl chloride-vinyl acetate copolymer 120 g
- the markings 19 are preferably elements applied in a printing process after the application of the first adhesive layer, for example special graphic elements, a font - visible only under certain viewing conditions - etc.
- the markings 19 start from one Decorative varnish that responds to UV light is formed, which can be composed as follows:
- the pressure 20 applied to the free surface of the adhesive layer 15 is, as already mentioned, generated by means of common printing processes, for example with the aid of Laser printers, thermal transfer printers, etc. It would theoretically even be conceivable to add further markings instead of a print 20. Laser or thermal transfer printing are preferred, however, because in this case, due to the fact that the transfer film is fixed on the substrate 8 under the influence of heat, it can be assumed that the particles generating the pressure also adhere at least partially directly to the substrate 8. If, in such a case, an attempt is then made to detach the decorative layer arrangement 7 from the substrate 8, it is to be expected that at least remnants of the identification print 20 will also adhere so firmly to the substrate 8 that the decorative layer arrangement 7 will detach without traces cannot be reached.
- the transfer foil is usually produced in such a way that first a hot stamping foil 6 is produced according to the usual methods, i.e. essentially by means of a printing method, and this hot stamping foil 6 is then firmly connected with an adhesive bond consisting of the carrier foil 1 and the base foil 3 by means of the permanent adhesive 4 , for example by a lamination process known per se.
