Description

The invention relates to a method for producing polymer security papers or polymer security papers with a security feature and a polymer security paper or polymer security paper produced according to this process.

The invention also relates to a security element, in particular for use in a method according to one of claims 1 to 12 and/or for producing the polymer security according to claim 13, comprising a transfer film, which transfer film has at least one security feature and a detachable carrier film.

Polymer securities or polymer security papers of the type mentioned at the outset are usually used in order to increase the counterfeit security of securities or security papers, such as banknotes, identity cards, credit cards, ATM cards, tickets, etc.

According to the prior art, it is not technically possible in the case of polymer securities or polymer security papers to apply a security feature in the form of a security thread. In particular, it is not possible with polymer securities or polymer security papers to introduce a customary or conventional security thread directly into the polymer, as is currently the case with securities or security papers made of paper or fibers.

In order to remedy this disadvantage, security threads in polymer security papers or polymer security papers are only imitated by means of printing technology. However, security threads printed in this way are of unsatisfactory quality in comparison to the security threads known from securities or security papers made of paper or fibers and therefore cannot guarantee a user a sufficiently high protection against forgery.

The object of the present invention was to overcome the disadvantages of the prior art and to provide a device and a method by means of which a user is able to purchase polymer securities or polymer security papers with one or more highly counterfeit-proof security features manufacture.

This object is achieved by a device and a method according to the claims.

The invention relates to a method for producing polymer securities or polymer security papers with at least one security feature, comprising a polymer substrate made of at least one polymer.

• Bereitstellen eines Polymersubstrats aus zumindest einem Polymer mit einer ersten Substratseite und einer zweiten Substratseite,
• Bereitstellen eines Sicherheitselements, umfassend eine Transferfolie, welche Transferfolie zumindest ein Sicherheitsmerkmal und eine lösbare Trägerfolie umfasst,
• zumindest abschnittsweises Auftragen der Transferfolie auf die erste Substratseite und/oder auf die zweite Substratseite,
• Verbinden des zumindest einen Sicherheitsmerkmals mit der ersten Substratseite und/oder der zweiten Substratseite,
• Entfernen der lösbaren Trägerfolie.

The following procedural steps are planned:

• Providing a polymer substrate made of at least one polymer with a first substrate side and a second substrate side,
• Providing a security element, comprising a transfer film, which transfer film comprises at least one security feature and a detachable carrier film,
• at least partially applying the transfer film to the first substrate side and/or to the second substrate side,
• Connecting the at least one security feature to the first substrate side and/or the second substrate side,
• Removing the detachable backing film.

This process creates the possibility of producing polymer securities or polymer security papers with one or more highly forgery-proof security features. The security element according to the invention, which comprises a transfer film, has the advantage that the entire portfolio of security features known from the prior art, which is also used in conventional security threads, can be used here. By applying the transfer film at least in sections, security features can be applied to the polymer substrate in the required number and size. The connection of the security feature or security features to the polymer substrate leads to their permanent transfer to the polymer substrate. After bonding, the detachable carrier film can be easily and effortlessly removed or peeled off, leaving the security feature or features permanently on the polymer substrate.

Polymer securities or polymer security papers are currently used particularly frequently for low denominations. On these banknotes - among other things for cost reasons - usually no expensive security features, such as in the form of Hologram stripes, applied. The method according to the invention enables a user to apply the security element or the transfer film directly during production of the polymer substrate, which also has a positive effect on the production costs, among other things. With this innovative process, polymer securities or polymer security papers can now also be provided with one or more high-quality and highly forgery-proof security features. The small thickness of the polymer banknote that can be achieved with this method is a major advantage. This proves to be particularly advantageous when stacking, but also when printing.

Furthermore, it can be expedient if the detachable carrier film is made of plastic, in particular made of a translucent plastic, the detachable carrier film preferably being at least one of the materials from the group polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene ( MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyetherketone (PEK), polyethyleneimide (PEI), polysulfone (PSU), polyaryletherketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC ) ethylene tetrafluoroethylene (ETFE), polytetrafluoroethylene (PTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF) and ethylene tetrafluoroethylene hexafluoropropylene fluoroterpolymer (E FEP) and/or mixtures and/or copolymers of these materials or is made from at least one of these materials.

Furthermore, it can be provided that thermal energy and/or pressure is used to connect the security feature to the polymer substrate. Application or connection technologies with the effect of pressure and/or the effect of thermal energy can enable a permanent connection between individual layers of a film or with a polymer substrate.

In addition, it can be provided that the detachable carrier film has a thickness of between 6 and 100 μm, preferably 8 and 50 μm, particularly preferably 10 and 36 μm, in particular 12 and 23 μm. These layer thicknesses can have an advantageous effect on the stability of the transfer film and thus make it easier to handle. Furthermore, they simplify Layer thicknesses the removability of the carrier film from the polymer substrate. A simple and effortless detachability of the detachable carrier film can have a positive effect on the efficiency of the process.

Also advantageous is an embodiment according to which provision can be made for a separating layer to be arranged between the detachable carrier film and the security feature, which separating layer is designed to facilitate the removal of the detachable carrier film. In this way it can be ensured that the carrier film can be detached completely and in one piece. A simple and effortless detachability of the detachable carrier film can have a positive effect on the efficiency of the process.

According to one development, it is possible for the separating layer to be formed by a separating lacquer.

Furthermore, it can be expedient if the transfer film is delimited on its outside by the detachable carrier film and if the transfer film is delimited on its inside by a connecting layer, which connecting layer is arranged in such a way that the connection of the security feature to the polymer substrate is facilitated. This further development can bring about an improved connection between the individual layers of the transfer film and in particular the connection of the security feature to the polymer substrate can be facilitated or improved.

In addition, it can be provided that the connecting layer is formed by a heat-sealing lacquer or an adhesive.

Furthermore, it can be provided that an adhesion promoter layer is formed between the security feature and the connection layer, which adhesion promoter layer is arranged to facilitate the connection of the security feature to the connection layer. This further development can bring about an improved connection between the individual layers of the transfer film and in particular the connection of the security feature to the polymer substrate can be facilitated or improved. In particular, this measure can have a positive effect on the life of the polymer security paper or the polymer security paper.

According to one particular embodiment, it is possible for the security feature to have an embossed layer, a partially metallized layer, a fluorescent layer, a printed layer, a magnetic coding and/or an optically variable feature, in particular a hologram and/or a color-shifting coating , For example, a coating having at least one color-shifting thin-film element is formed. This form has the advantage that a user can choose from a large portfolio and a large number of possible combinations of security features. As a result, a high level of security against counterfeiting can be achieved.

According to an advantageous development, it can be provided that the polymer substrate is cut after the transfer film has been applied at least in sections. This process engineering measure can have a positive effect on the efficiency of the process.

In particular, it can be advantageous if the transfer film is applied to the polymer substrate with a width of 0.5-30 mm, preferably 0.8-20 mm, particularly preferably 1-15 mm, in particular 1.5-10 mm. Advantageously, the transfer film has a narrow width compared to the polymer substrate, since this allows the shape of a security thread to be implemented.

Furthermore, a polymer security paper or polymer security paper with at least one security feature, comprising a polymer substrate made of at least one polymer, can be provided. The polymer security paper or the polymer security paper is produced in a method according to one of Claims 1 to 12.

With the polymer security paper or polymer security paper according to the invention, a user is provided with polymer security papers or polymer security papers with a highly forgery-proof security feature. With the security element according to the invention, which includes a transfer film, the entire known portfolio of security features that is used with conventional security threads can be used. With the transfer film applied at least in sections, security features can be used in the required number and size. The security feature or features are advantageously permanently connected to the polymer substrate. After connecting, the detachable backing film can be easily and effortlessly be removed or peeled off so that the security feature or security features remain on the polymer substrate.

Polymer securities or polymer security papers are frequently used for low denominations in particular. Expensive security features, for example in the form of hologram strips, are not usually applied to these banknotes, for cost reasons among other things. With the polymer security paper or polymer security paper according to the invention, a user is provided with a security paper or security paper which is provided with one or more high-quality and highly counterfeit-proof security features. The small thickness of the polymer security paper or polymer security paper according to the invention, in particular the polymer bank note, brings a great advantage. This proves to be particularly advantageous when stacking, but also when printing.

The above-mentioned object can also be achieved according to the invention with a security element of the type mentioned at the outset in that the transfer film is delimited on its outside by the detachable carrier film and that the transfer film is bounded on its inside by a connecting layer, in particular in the form of a heat-sealing lacquer, for connection to a polymer substrate.

For a better understanding of the invention, it is explained in more detail with reference to the following figures.

As an introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numbers or the same component designations, it being possible for the disclosures contained throughout the description to be applied to the same parts with the same reference numbers or the same component designations. The position information selected in the description, such as top, bottom, side, etc., is related to the figure directly described and shown and these position information are to be transferred to the new position in the event of a change of position.

the figure 1 shows a first embodiment of a polymer security paper 1 or a polymer security paper 2 with a security feature 3 in an exploded view. In the figure 1 several steps of the manufacturing process are shown simultaneously. The polymer security paper 1 or the polymer security paper 2 comprises a polymer substrate 4 . This polymer substrate has a first substrate side 5 and a second substrate side 6 . In the manufacturing process of this polymer security paper 1 or polymer security paper 2, the security feature 3 is initially on or in a security element 7. This security element 7 comprises a transfer film 8, the transfer film 8 also comprising a detachable carrier film 9 in addition to the security feature 3. The security element 7 and the transfer film 8 are in the figure 1 shown twice to clarify the manufacturing process. On the one hand, the security element 7 or the transfer film 8 is shown separately from the polymer substrate 4 . In addition, the security element 7 or the transfer film 8 connected to the polymer substrate 4 are sketched.

In the exemplary embodiment shown, the transfer film 8 has a narrow strip shape—compared to the polymer security paper 1 or the polymer security paper 2 . However, the transfer film 8 can of course also have other shapes or sizes and can also be used in other numbers. The transfer film 8 is in the course of the manufacturing process of the polymer security paper 1 or the polymer security paper 2 at least applied in sections to the first substrate side 5. However, it is also conceivable and sensible if the transfer film 8 is applied to the second substrate side 6 or is also applied to both substrate sides 5, 6. As shown, the security feature 3 is subsequently connected to the first substrate side 5 and the detachable carrier film 9 is removed. In this way, the security feature 3—represented by dashed lines—remains permanently on the polymer security paper 1 or on the polymer security paper 2.

It is possible for the detachable carrier film 9 to be made from plastic, in particular from a translucent plastic, with the detachable carrier film 9 preferably being at least one of the materials from the group consisting of polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene ( MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyetherketone (PEK), polyethyleneimide (PEI), polysulfone (PSU), polyaryletherketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC ) ethylene tetrafluoroethylene (ETFE), polytetrafluoroethylene (PTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF) and ethylene tetrafluoroethylene hexafluoropropylene fluoroterpolymer (EFEP) and/or r mixtures and / or copolymers of these materials comprises or is made of at least one of these materials.

Advantageously, thermal energy and/or pressure can be used to connect the security feature 3 to the polymer substrate 4 . In the process for producing the polymer security paper 1 or the polymer security paper 2, it can be advantageous if the detachable carrier film 9 has a thickness of between 6 and 100 µm, preferably 8 and 50 µm, particularly preferably 10 and 36 µm, in particular 12 and 23 µm. The security feature 3 can be an embossed layer, a partially metallized layer, a fluorescent layer, a printed layer, a magnetic coding and/or an optically variable feature, in particular a hologram and/or a color-shifting coating, for example at least one color-shifting thin-film element having coating, are formed. It can also be expedient if the polymer substrate 4 is cut after the transfer film 8 has been applied. The transfer film 8 can with applied to the polymer substrate 4 with a width of 0.5-30 mm, preferably 0.8-20 mm, particularly preferably 1-15 mm, in particular 1.5-10 mm.

In the Figures 2 to 5 two further and possibly independent embodiments of the polymer security paper 1 and the polymer security paper 2 are shown, with the same reference numbers or component designations as in the previous one being used for the same parts figure 1 be used. In order to avoid unnecessary repetition, therefore, reference is made to the detailed description in the foregoing figure 1 pointed out or referred to.

the figure 2 shows a second embodiment of a polymer security paper 1 or a polymer security paper 2 in cross section with a detachable carrier film 9.

The polymer security paper 1 or the polymer security paper 2 comprises a polymer substrate 4 . This polymer substrate has a first substrate side 5 and a second substrate side 6 . In the manufacturing process of this polymer security paper 1 or polymer security paper 2, the security feature 3 is initially on or in a security element 7. This security element 7 comprises a transfer film 8, the transfer film 8 also comprising a detachable carrier film 9 in addition to the security feature 3. The transfer film 8 is applied at least in sections to the first substrate side 5 in the course of the manufacturing process of the polymer security paper 1 or the polymer security paper 2 . However, it is also conceivable and sensible if the transfer film 8 is applied to the second substrate side 6 or is also applied to both substrate sides 5, 6. The transfer film 8 is delimited on its outside, i.e. on its side facing away from the polymer substrate 4, by the detachable carrier film 9 and on its inside, i.e. on its side facing the polymer substrate 4, by the security feature 3. The security feature 3 is subsequently connected to the first substrate side 5 and the detachable carrier film 9 is also removed. The security feature 3 thus remains permanently on the polymer security paper 1 or on the polymer security paper 2.

In the figure 3 1 is the second embodiment of a polymer security paper 1 or a polymer security paper 2, also in cross section, but after removing the detachable Carrier film 9 is shown, with the security feature 3 remaining on the polymer substrate 4 .

the figure 4 shows a third embodiment of a polymer security paper 1 or a polymer security paper 2 in cross section with a detachable carrier film 9.

The polymer security paper 1 or the polymer security paper 2 comprises a polymer substrate 4 . This polymer substrate has a first substrate side 5 and a second substrate side 6 . In the manufacturing process of this polymer security paper 1 or polymer security paper 2, the security feature 3 is initially on or in a security element 7. This security element 7 comprises a transfer film 8, the transfer film 8 also comprising a detachable 9 in addition to the security feature 3. The transfer film 8 is applied at least in sections to the first substrate side 5 in the course of the manufacturing process of the polymer security paper 1 or the polymer security paper 2 . However, it is also conceivable and sensible if the transfer film 8 is applied to the second substrate side 6 or is also applied to both substrate sides 5, 6. The transfer film 8 is delimited on its outside, i.e. on its side facing away from the polymer substrate 4, by the detachable carrier film 9 and on its inside, i.e. on its side facing the polymer substrate 4, by an optional connecting layer 11. The security feature 3 is subsequently connected to the first substrate side 5 and the detachable carrier film 9 is also removed. The security feature 3 thus remains permanently on the polymer security paper 1 or on the polymer security paper 2.

In addition to those in the figure 1 In the method steps described, it can be expedient here if a separating layer 10 is arranged between the detachable carrier film 9 and the security feature 3, which is designed to facilitate the removal of the detachable carrier film 9. The separating layer 10 can be formed by a separating lacquer. Furthermore, the transfer film 8 can be delimited on its outside by the detachable carrier film 9 and on its inside by the optional bonding layer 11 which is arranged to facilitate the bonding of the security feature 3 to the polymer substrate 4 . This connecting layer 11 can be formed, for example, by a heat-sealing lacquer or an adhesive. Like in the figure 4 shown it can also be advantageous if between the security feature 3 and the connection layer 11 an adhesion promoter layer 12 is formed, which is arranged in such a way that the connection of the security feature 3 to the connection layer 11 is facilitated.

In the figure 5 the third embodiment of a polymer security paper 1 or a polymer security paper 2 is also shown in cross section, but after the detachable carrier film 9 has been removed, with the security feature 3 remaining on the polymer substrate 4 . In addition, according to this third embodiment, the separating layer 10, the connecting layer 11 and the adhesion promoter layer 12 also remain on the polymer substrate 4.

Release layer 10, tie layer 11 and adhesion promoter layer 12, as in the third embodiment or den Figures 4 and 5 shown together are also independently conceivable in further embodiments. These layers are therefore not necessarily tied to the formation in a common embodiment. In particular, these layers can also be formed individually on a polymer security paper 1 or a polymer security paper 2 .

The exemplary embodiments show possible variants, whereby it should be noted at this point that the invention is not limited to the specifically illustrated variants of the same, but rather that various combinations of the individual variants with one another are also possible and this possibility of variation is based on the teaching on technical action through the present invention in skills of the specialist working in this technical field.

The scope of protection is determined by the claims. However, the description and drawings should be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The task on which the independent inventive solutions are based can be found in the description.

All information on value ranges in the present description is to be understood in such a way that it includes any and all sub-ranges, for example the information 1 to 10 is to be understood in such a way that all sub-ranges, starting from the lower limit 1 and the upper limit 10 are also included, ie all partial ranges start with a lower limit of 1 or greater and end with an upper limit of 10 or less, eg 1 to 1.7, or 3.2 to 8.1, or 5.5 until 10.

Finally, for the sake of clarity, it should be pointed out that some elements are shown not to scale and/or enlarged and/or reduced in size for a better understanding of the structure.
