Definitions

  • the invention relates to a polymer substrate for the production of polymer securities or polymer security paper, a polymer security paper or polymer security paper, and a method for producing a polymer substrate.
  • 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.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a polymer substrate and a method for producing a polymer substrate by means of which polymer securities or polymer security papers with one or more highly forgery-proof security elements or security elements with Security features are manufacturable.
  • This object is achieved by a polymer substrate, a polymer security paper or polymer security paper and a production method according to the claims.
  • the polymer substrate according to the invention for the production of polymer securities or polymer security papers comprises a polymer carrier layer and at least one security element. It is provided that the security element is applied to and/or in the polymer carrier layer and that a primer is applied at least in sections to a first substrate side and/or a second substrate side of the polymer substrate.
  • the primer is arranged at least in sections between the polymer carrier layer and the security element and/or covers the security element and/or the polymer carrier layer at least in sections, with areas of the security element covered by the primer being less clearly visible than areas not covered by the primer Areas of the security element and/or as areas of the polymer carrier layer not covered by the primer.
  • the polymer substrate according to the invention creates the possibility or basis for producing polymer securities or polymer security papers with one or more highly counterfeit-proof security elements or security elements with one or more security features.
  • a banknote manufacturer is provided with a starting material which, in principle, can be further processed like or similar to paper for paper banknotes.
  • a banknote manufacturer can thus produce both paper banknotes and polymer banknotes, for example using the same machines or process steps, or using minor modifications. This brings advantages in terms of profitability of the entire production chain, while at the same time achieving a high product quality.
  • security element can refer to various types of security elements familiar to a person skilled in the art.
  • security elements can be designed as security threads, security strips and the like, with other advantageous types of security elements known to those skilled in the art also being conceivable.
  • a security element can have one or more similar or different security features or security features.
  • Security features can be optically variable Features, features that are optically recognizable in transmission or reflection, machine-readable features, substances or features that absorb and/or re-emit electromagnetic waves.
  • security features can be formed as holograms, embossed layers, partially metallized layers, fluorescent layers, printed layers, and/or magnetic coding and/or optically variable features, in particular around holograms and/or around color-changing coatings, for example around a color-changing thin-film element having coatings be.
  • Security features can be arranged in or on security elements or be integrated into this, which thus act as a kind of carrier for the security feature or features. If a security element is mentioned in the following description, it can therefore be a security element with an individually configured security feature. Basically, it is of course also conceivable that the security element is designed with only one security feature.
  • the primer can describe a single layer as well as a compound or a layering of several layers. This can involve, for example, several layers or plies of the same type, but also several different layers.
  • the security element(s) formed in or on the polymer substrate ensures an additional level of security against forgery, because the visibility of the security element(s) is reduced as a result of the primer applied. According to the invention, those areas on the first and/or second substrate side on which or in which a security element covered with a primer is formed can be perceived less well or less clearly than those areas of the polymer carrier layer with and/or without an overlying one Primer.
  • the primer which serves to cover the security element or elements, but can also enable a later, individual printing of the polymer substrate by a banknote manufacturer, is applied at least in sections to the security element or elements and/or to the polymer carrier layer, so that at least selected areas are covered and are not or at least less well or less clearly or less strongly contrasted visible.
  • This effect that areas covered by the primer are less clearly visible than areas not covered by the primer, is primarily recognizable or perceptible to an observer when he looks at that substrate side of the polymer substrate to which the primer is applied.
  • the polymer substrate can also be on both Pages have a primer. In these forms, the effect of the less good visibility of covered areas on both sides of the substrate would be recognizable.
  • the security element or elements can be arranged on or in both outer surfaces of the polymer carrier layer.
  • the at least one security element has the advantage that the entire portfolio of security elements known according to the prior art, which is also used with conventional papers for the production of paper banknotes, can be used.
  • it can be the case that an observer only recognizes the security element covered by the primer when he observes the polymer substrate in transmitted light.
  • the polymer carrier layer is made thinner at the points in which the security element or elements is to be applied. It may be that the visibility of the security element is additionally reduced, or that the location at which the security element is arranged is hidden or “concealed” because there are no elevations, or elevations that are barely perceptible. In this case, the primer can also contribute to “concealing” the areas with security elements.
  • the areas of the security element covered by the primer are not visible when viewed from above and are visible when viewed through, or that the areas of the security element covered by the primer are better visible when viewed through than when viewed from above .
  • This advantageous embodiment can make it easier for a user to check the authenticity of a polymer banknote by holding it against the light or looking through it. In this way, a further contribution can be made to counterfeit security in polymer banknotes.
  • the metal layer can—to name just a few examples—contain gaps in the form of characters, letters, patterns, motifs, geometric figures, guilloches and also lines.
  • the security element and/or the polymer carrier layer and/or the primer can be covered at least in sections with a cover layer, with areas of the security element covered by the cover layer being less clearly visible than those not covered by the cover layer Areas of the security element and/or as areas of the polymer carrier layer not covered by the cover layer and/or as areas of the primer not covered by the cover layer.
  • optical effects can be achieved by overprinting selected areas—for example also in the course of bank note printing—and in particular a visibility contrast between areas with a cover layer and areas without a cover layer can be brought about.
  • the primer is applied by means of a printing process.
  • a uniform and level primer or primer layer can be implemented in an economical manner. This can be advantageous in particular in the case of further processing of the polymer substrate in the course of subsequent banknote printing and can contribute to a high product quality.
  • the primer it would of course also be conceivable and possibly advantageous for the primer to be applied by painting, dip coating, spray coating or roller coating. It is also conceivable to apply the primer using vacuum-based coating methods, such as plasma coating or PVD and CVD coating.
  • the primer is designed to be printable. Good printability can be important in further processing of the polymer substrate in the course of banknote printing and can sometimes enable a satisfactory or even high final quality of a polymer security paper or polymer security paper.
  • good printability of the primer or the polymer substrate can have a positive effect on the longevity or resilience of a polymer banknote.
  • good printability can be achieved by an even primer, or also by a structure that takes up a printing ink well, or by the material of the primer.
  • the primer covers the entire surface of the polymer carrier layer and/or the security element. For reasons of protection against forgery of polymer banknotes, it can sometimes be advantageous if the security element or elements are completely covered and are therefore not visible or only visible poorly or indistinctly when viewed from above.
  • the primer it is possible for the primer to partially cover the polymer carrier layer and/or the security element.
  • Such areas of the security element or elements, which are not covered by the primer and are therefore visible when viewed from above, are often referred to in the industry as windows.
  • Security elements designed in this way in the form of a thread are often referred to as window threads.
  • Such windows can be designed both as so-called half windows and as full windows.
  • a half-window is a gap in the primer on just one side of the polymer substrate, or on one side of the primer. If the primer is applied to both sides of the polymer substrate and gaps are provided opposite or at least partially opposite or overlapping in the primer on both sides, then in technical jargon one speaks of a full window.
  • These windows can make it easier for a user to verify the authenticity of a polymer banknote in a simple and quick manner.
  • security against forgery can be improved because an exact positioning of windows makes it considerably more difficult to imitate or forge polymer banknotes.
  • the primer is designed to be diffusely scattering, in particular that the primer produces a white color impression in daylight.
  • This design can have a particularly positive effect on a polymer banknote that can be produced from the polymer substrate, since a white primer layer or surface can enable particularly high-quality subsequent printing or other application of motifs, numbers and the like.
  • Such layers or primers are also known as opacifying layers.
  • the ink used in this case is also referred to as opacity ink.
  • the polymer carrier layer is made of plastic, in particular made of a translucent plastic, with the polymer carrier layer preferably 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),
