Definitions
- Bank note with anti-viral protective coating method of manufacturing bank note with anti-viral protective coating and use of bank note with anti-viral protective coating as anti-viral article
- the invention relates to a bank note with a carrier substrate, at least two security elements and a protective lacquer. At least one of the two security elements is designed as a print.
- the printing is formed between the carrier substrate and the protective lacquer. Furthermore, the outer surface of the banknote is formed by the protective lacquer.
- the carrier substrate is at least partially surrounded by the protective lacquer. Furthermore, the protective lacquer or the protective lacquer layer is designed to protect the printing and the carrier substrate.
- the invention also relates to a corresponding method and use.
- a banknote is a document that serves as a means of payment in a specific country or currency area, is issued by an authorized institution and is usually denominated in a round denomination of a currency unit.
- Banknotes are a popular means of payment and usually change hands regularly.
- a banknote is usually touched by a payer with his bare hand and passed to a payee.
- the payee usually also accepts the banknote with his bare hand.
- germs can be found on the bank note - as on any other object of everyday life, for example a door handle or a keyboard of a credit card terminal for entering a PIN for a credit card.
- These germs can be in the form of algae, bacteria, parasites, fungi, prions, protists, viruses or viroids, for example. Viruses have turned out to be a particularly relevant germ.
- the object is to provide a banknote which has an antiviral effect and to create a method for producing a corresponding banknote.
- a banknote according to the invention has a carrier substrate, at least two security elements and a protective lacquer. At least one of the two security elements is designed as a print. The printing is formed between the carrier substrate and the protective lacquer. The outer surface of the bank note is formed by the protective lacquer. Furthermore, the carrier substrate is at least partially surrounded by the protective lacquer, and the protective lacquer is designed to protect the printing and the carrier substrate.
- the protective lacquer is designed as an antiviral protective lacquer and has an antiviral roughness on the outer surface.
- the invention is based on the finding that the roughness gives the protective coating a stronger antiviral effect. It has surprisingly been found that viruses, particularly enveloped viruses, particularly Coronaviridae, survive for a shorter time on a rougher surface than on a smooth surface. The persistence (lifespan) of the virus therefore depends on the degree of roughness of the surface. There is therefore a passive effect in which viral colonization is prevented by the surface structure. This can also be described, for example, with the buzzword “safe by design”, analogous to the well-known lotus effect or hydrophobic treatment. A possible reason for the virucidal effect of roughness is that the viruses dry out faster on a rough surface than on a smooth surface and then no longer persist or are at least less or no longer infectious.
- a virus is usually transmitted as an aerosol, by breath/coughing or contact. According to findings, a virus is usually only able to survive in an aqueous environment.
- the antiviral protective coating increases the stretched surface and accelerates the evaporation of liquid, especially water.
- micropores or capillaries can also be produced as an absorber.
- the absorber can be special fillers with a hydrophilic, microporous surface, for example in an ink-accepting layer of the bank note.
- a watery component of the protective coating then breaks through the ink acceptance layer (physical drying). Or the aerosol droplets spread more on the enlarged surface, the layer thickness decreases and the evaporation time is reduced.
- a porous surface can contribute to active antiviral components in the paint or/and in or on the carrier substrate in contact with the virus due to faster diffusion of organic antiviral substances or, in the case of silver, singlet oxygen kills virus faster.
- the antiviral roughness is irregular.
- the bank note is in the form of a freshly printed bank note or an unused bank note which was not yet in cash circulation.
- the antiviral protective lacquer has a large number of elevations and/or depressions, ie a texture. This texture can effectively counteract viruses.
- the protective lacquer has a protective function against mechanical influences on the bank note.
- the protective lacquer with the antiviral roughness to have an extended surface area of at least 80%, preferably at least 100%, in particular at least 120%, more particularly at least 150%.
- the antiviral roughness with the stretched surface increases the virucidal effect of the protective coating.
- the protective lacquer with the antiviral roughness preferably has a stretched surface of at most 500%.
- An increased susceptibility to dirt can be observed on surfaces that have been roughened too much.
- the stretched surface of at most 500% can effectively limit the soiling of the banknote.
- the stretched surface describes the relationship between an ideally flat surface and a real measuring surface and is therefore a measure of the roughness of the surface.
- the real area is significantly larger than the ideally flat or smooth area.
- the extended surface area is also known by the term actual surface area or actual surface area ratio or developed interface ratio and is used described, for example, by the series of standards DIN EN ISO 25178, which relates to areal roughness measurement.
- Stretched surface area is the percentage of additional area added to the developed area (surface area of the measured shape) due to texture compared to the area of the measured shape in direct plan view.
- An ideally flat surface has an actual surface area, or stretched surface area, of 0%.
- a stretched surface of 80% is therefore 1.8 times larger than an ideally flat surface.
- a stretched surface of 120% is therefore 2.2 times larger than an ideally flat surface.
- the antiviral roughness is formed by open pores and the respective opening of the pores is formed with a semimajor axis or a diameter of at least 1 ⁇ m and at most 20 ⁇ m in the plane of the outer surface of the bank note. Due to the open pores, the desired drying out of the viruses can take place even faster.
- the antiviral protective lacquer is formed with a matting agent, with a ratio of matting agent to an antiviral active substance of the protective lacquer being greater than 10:1, in particular percentage by weight. That means there is one part antiviral agent to at least ten parts matting agent.
- the matting agent is designed in particular as a filler, silicate, silicic acid, quartz sand, micronized wax comprising zinc and/or PTFE (polytetrafluoroethylene) and/or organic filler.
- the matting agent not only reduces the gloss, but also leads to greater porosity and/or greater roughness.
- the proportion of matting agent is above 10 percent by weight.
- the ratio of matting agent to antiviral active ingredient is between 10:1 and 20:1, in particular weight percent.
- the antiviral protective lacquer is produced with hydrophilic, pre-swollen microparticles.
- the protective lacquer is mixed with hydrophilic, swellable microparticles that are preswollen in water. In the swollen state, the microparticles have in particular a diameter of 2 ⁇ m to 30 ⁇ m. Due to the temperature development, for example from infrared radiation from mercury radiators During UV drying, the bound water evaporates, so that there are small holes or microcracks in the protective coating at these points, depending on the particle size of the swollen polymer particles and the bound water content.
- a mixture of water and alcohol can be used to accelerate drying of the polymers, or a mixture of water and glycerine to slow down physical drying. This is advantageous because the specific surface area is increased further. Furthermore, this also reduces the barrier effect with respect to migrating active substances present below or within the protective lacquer layer.
- the antiviral protective lacquer is produced with light-unstable polymer particles.
- the light-unstable polymer particles can be, for example, a shell-core particle.
- the core can, for example, be designed as a UV light absorber such as nanoscale titanium dioxide.
- the shell can be formed, for example, as a light-unstable polymer.
- the protective lacquer in particular a UV lacquer, is cured or crosslinked with a very high dose of UV radiation of 250 nm to 400 nm. If polymer particles that are unstable to UV radiation are used, they decompose and thus become porous. In this case, too, there is an advantageous enlargement of the stretched surface or actual surface of the protective lacquer. The antiviral effect is increased.
- titanium dioxide particles of the anatase modification are added to the paint, preferably on a nanoscale, in order to maintain the transparency of the paint.
- the polymers in the vicinity of the titanium dioxide particles i.e. crosslinked monomers and prepolymers, in the immediate vicinity of the titanium dioxide particles, which in turn leads to structuring on the surface of the protective coating and the virucidal effect of the protective coating continues elevated.
- particles with a high specific weight in g/cm 3 are used, which is at least twice as high as that of the binder of the protective lacquer.
- the binder of the protective lacquer has in particular a specific weight of 0.85 g/cm 3 to 1.0 g/cm 3 .
- these particles sink to the bottom, ie in the direction of the side of the protective lacquer facing the carrier substrate, and thus form craters on the surface of the protective lacquer.
- the prerequisite is in particular that the size of the particles is smaller than the thickness of the applied protective lacquer layer or the protective coating is.
- the paint film hardens during or after crater formation.
- An advantageous material is barium sulfate (4.5 g/cm 3 ), since it is also transparent.
- particles with a diameter greater than the layer thickness of the protective lacquer are used.
- the particles have a diameter of 2 ⁇ m to 50 ⁇ m.
- the layer thickness of the protective lacquer is in particular between 1 ⁇ m and 4 ⁇ m. After application, these particles sink to the bottom, ie in the direction of the side of the protective lacquer facing the carrier substrate, and thus form craters on the surface of the protective lacquer.
- a particular requirement is that the size of the particles is smaller than the thickness of the applied protective lacquer layer or protective lacquer.
- An advantageous material is barium sulfate because it is also transparent.
- the antiviral protective lacquer is produced by emulsifying an alcohol-water mixture.
- water, alcohol and/or a water-alcohol mixture is emulsified as small droplets using a dissolver.
- the size of the droplets is preferably dependent on the shear rate and/or the interfacial tension of the protective lacquer.
- leveling agents are preferably dispensed with in the paint in order to keep the droplets in the paint stable after the shear forces have been applied.
- the antiviral protective lacquer is produced by dispersing a gas.
- gases such as air
- the polymeric paint layer or the protective paint becomes thinner locally and due to enclosed pm air bubbles or air bubbles that have burst open on the surface, a crater in the pm range occurs and/or there are defects in the paint layer in the pm area.
- Heavy gas such as sulfur hexafluoride is preferably used instead of air, as this can be processed more easily in the printing machine, in particular the coating storage tank or the chamber doctor blade in a flexographic printing machine. This prevents air bubbles from floating up.
- polyethylene glycol in particular polyethylene glycol 400 or higher molecular weight, as microparticles, in particular 1 pm to 30 pm, to the UV-drying protective lacquer Particle size, to be added in concentrations of 5% to 15%, since the water content of the virus aerosols is absorbed by the polyethylene glycol particles.
- the antiviral protective lacquer is produced by micro-perforation.
- the microperforation is produced in particular by material removal and/or material displacement.
- the microperforation is produced in particular with a needle corona.
- banknotes coated with the protective lacquer and UV-dried, preferably still in sheet form, and also before the individual banknotes are cut, can be processed by means of the needle corona in order to reliably produce the roughness.
- the antiviral protective lacquer is formed with transparent polyurethane particles or polymethyl methacrylate particles (PMMA).
- PMMA polymethyl methacrylate particles
- the antiviral protective lacquer is formed with a photosensitizer, which releases singlet oxygen on irradiation and/or is formed with nano-titanium dioxide in the anatase modification, which releases singlet oxygen on irradiation.
- the irradiation takes place in particular in the UV and/or in the short-wave VIS range.
- the singlet oxygen is generated, in particular by photocatalysis.
- the singlet oxygen has virucidal properties.
- the ink acceptance layer of the polymer substrate or hybrid substrate can also have particles or elements which lead to an increase in roughness.
- a standard coating can then be used for the final coating, i.e. after printing.
- the particles will also protrude after a final coating, since the protective coating is only applied in a smaller layer thickness, for example from 0.5 ⁇ m to 3 ⁇ m.
- the ink acceptance layer can also be applied in a structured manner between the carrier substrate and the protective lacquer in order to produce the roughness or the desired structure with an enlarged surface.
- This can also be applied in combination with one or more non-structured ink acceptance layers.
- the desired structures are, for example, by screen printing, eg 64 screen with 10% area coverage or by an autotypical gravure printing with cell depth variation or by means of inkjet printing.
- the roughness of the protective lacquer results from a partially different layer thickness of the ink-receptive layer and/or particles additionally contained in the ink-receptive layer, which are preferably thicker than the thickness of the protective lacquer applied.
- the antiviral roughness is carried out using the intaglio printing process as so-called blind embossing, i.e. printing without coloring the printing plate in these areas, or as intaglio printing with transparent white.
- the intaglio printing plate in particular outside the visually visible intaglio printing motifs, is preferably greater than or equal to 1 mm, in particular greater than or equal to 3 mm, spaced from these visually visible motifs with a uniform or irregular engraving with deeper-lying points, preferably in a range from 2 pm to 30 pm , in particular from 5 pm to 25 pm.
- Registered inking of the printing plate using a stencil roller or plate can ensure that, in the case of blind embossing, the printing plate is only inked for the visually visible intaglio motifs.
- these areas can be inked with the transparent, visually invisible intaglio printing ink using an additional stencil cylinder or a stencil plate.
- the spacing of at least 1 mm, preferably 3 mm, between the visually visible intaglio motifs and the visually invisible microstructuring of the substrate enables a clean transition between the visually visible motif and the visually invisible microstructuring of the substrate, which is caused by the wiping process after the coloring of the Printing plate is difficult to remove the excess ink from the printing plate.
- the area of the carrier substrate that has the microstructuring produced by intaglio printing leads to a raised, visually invisible structure on the printed side and to a depression on the opposite side and thus also to the desired enlargement of the stretched Surface.
- the microstructuring of the polymer substrate is preferably carried out using transparent intaglio printing ink that is not visually visible.
- the paint can also have matting agents in order to create open pores.
- the matting agent can also be applied in a structured manner.
- the antiviral protective lacquer is formed with nanosilver, silver salt and/or silver phosphate glass.
- Silver salt and/or silver phosphate glass has an antiviral and antibacterial effect. In combination with a rough surface or the antiviral roughness of the protective coating, viruses are combated even more effectively.
- the antiviral protective lacquer is formed with antiviral metal ions.
- Metal ions such as single positively charged copper ions (Cu(I) ions), exhibit antiviral properties. Together with the antiviral roughness of the protective coating, viruses are combated even more effectively.
- the antiviral protective lacquer is formed with 3-iodo-2-propynyl-butyl carbamate.
- the advantage here is that these compounds can also effectively kill fungi, for example.
- the banknote can thus be provided even more securely.
- the antiviral protective lacquer is produced as a UV-curing structured lacquer or sand lacquer in screen printing. As a result, the surface of the protective coating can be made even rougher. This increases the antiviral effect.
- the antiviral protective lacquer is made hydrophobic, in particular by water-repellent wax crystals.
- the protective coating can thus be protected from microbial infestation (lotus effect).
- the advantage here is that the surface is hydrophobic and the adhesion between deposits and the surface is reduced.
- the bank note has a smooth front side and a rough back side after a printing process in which at least one of the two security elements is applied and before the application of the protective lacquer smooth face is formed after application of the antiviral protective varnish with the antiviral roughness.
- the rough reverse side is formed in particular by an impression roller or a counter-pressure element during the printing of the banknote, in particular by gravure printing.

- virucidal metal ions such as copper, cobalt and/or zinc can also be added.
- a catalytic antiviral agent ie a substance that continuously produces the agent catalytically without being consumed in the process. Due to the resulting longer effectiveness of the antiviral property, the bank note 1 can remain in circulation longer before it is taken out of circulation, for example by a central bank, and replaced by a new bank note.
- the protective lacquer 5 provision is also made for the protective lacquer 5 to have an increased refractive index of at least 1.4.
- micro-optical elements such as, for example, micro-lenses can be easily recognized despite being coated with the protective lacquer 5 .
- the protective lacquer 5 is applied in particular as a UV-curing structured lacquer or sand lacquer using the screen printing process.
- the protective lacquer 5 is formed on all sides of the carrier substrate 2 .
- the carrier substrate is therefore completely surrounded by the protective lacquer 5 and is therefore also completely protected.

- the protective lacquer 5 with the antiviral roughness 8 has an actual surface area or a stretched surface area of at least 80%, preferably at least 100%, in particular at least 120%, more particularly at least 150%.
- the stretched surface can also depend on the type of carrier substrate 2 .
- the stretched surface area can be at least 50%, preferably at least 80%, in particular at least 100%.
- the polymer substrate is made entirely of polymer.
- the stretched surface area can be at least 80%, preferably at least 100%, in particular at least 120%.

- a high contact pressure is exerted on the carrier substrate 2 on the side to be printed for ink transfer.
- a counter-pressure is required on the side opposite the side to be printed, which counter-pressure is exerted, for example, by an impression roller.
- the back side ie the back side of the carrier substrate 2 after the intaglio printing process
- the back side is rougher than the front side.

- the protective lacquer 5 or the protective lacquer layer has open pores 13 and closed pores 14 .
- the open pores 13 can also be described as craters.
- the open pores 13 and/or the closed pores 14 are created by gas-filled bubbles and/or by small faulty coatings of the bank note 1 due to escaping gas.
- the antivirally effective roughness and defects in the interior of the protective lacquer are evident, which lead to the porosity, ie the open pores 13 and/or the closed pores 14 .
- the closed pores offer the advantage that when the protective lacquer 5 or the protective lacquer layer or the binder of the protective lacquer layer later wears down, they come to the outer surface 7 and thus contribute to the roughness. Furthermore, the barrier against diffusible active ingredients is lower at this point.
- the bank note 1 makes it possible for viruses to shorten the temporal effectiveness of viruses, since they dry out more quickly due to the antiviral roughness 8 than with known, smooth bank notes without antiviral roughness.

- Fillers 10 or particles are added to the protective lacquer 5, which produce or reinforce the roughness 8 with an antiviral effect.
- the fillers 10 are in particular spherical and only for simplified representation in Q erection of the figure compressed. Furthermore, no separation is shown between the protective lacquer 5 and the carrier substrate 2 . It is also not shown in more detail that the fillers 10 are coated with the protective lacquer 5 in the exemplary embodiment.

- the Abbott curve 15 has a histogram 16 which describes the distribution of the elevations of the protective lacquer 5.
- FIG. Furthermore, the Abbott curve 15 shows a cumulative sum histogram 17 in which the number of individual bins is summed up.
