Definitions
- the invention relates to a value document substrate, in particular a fit document of value such as a banknote, or a not yet fit for circulation, in particular unprinted, security paper for generating a document of value such as a bank note.
- the invention also relates to a method for disinfecting the value document substrate.
- the printing process usually takes place in several printing steps, whereby a variety of successive printing and finishing processes can be used.
- One of the first steps here is usually a single-color or multi-color background printing using the offset and / or letterset process.
- the printing equipment used for this can vary greatly and is dependent on the following parameters:
- paper substrate e.g. substrates based on cotton fibers; substrates based on mixed fibers, mixed fibers being in particular cotton, flax, linen, cellulose and synthetic fibers; substrates based on plastic films; impregnated and precoated substrates);
- substrates to be printed which have an inhomogeneous structure (e.g. paper substrates provided with a film element; partially preprinted substrates; substrates with flat elements partially applied on the basis of screen printing);
- an inhomogeneous structure e.g. paper substrates provided with a film element; partially preprinted substrates; substrates with flat elements partially applied on the basis of screen printing;
- the printing equipment of the subsequent printing steps can be adapted, which is associated with a lot of effort and high costs.
- the drying of a printed substrate can also be accelerated by adding metal-containing drying agents.
- Oxidative drying printing inks i.e. printing inks that do not belong to the UV inks or UV varnishes
- a drying agent or siccative Drying agents are in particular organic salts of certain metals such as cobalt (e.g. cobalt octoate, cobalt naphthenate), manganese, calcium (e.g. calcium octoate), zirconium or cerium.
- Metal-containing drying agents only develop their effect in the presence of oxygen. Provided that storage and transport are largely carried out in the absence of air, a drying agent can be incorporated into the paint at the factory.
- the disadvantage of these drying agents is that the use of (heavy) metal compounds is problematic for reasons of work-related safety and health hazards. A low use concentration would therefore be desirable, but this leads to long drying times.
- the drying of a printed substrate can also be accelerated by adding peroxide-containing substances such as inorganic or organic peroxides. When they disintegrate, these cause radical harm free of substances and thus accelerate the oxidative drying of the paint layer. This also works in places where there is a lack of air or oxygen, consequently also in the case of substrates that do not turn away and in high or large-area stacks of valuable documents.
- peroxide-containing substances can only be added to the ink relatively shortly before printing, because the ink cannot be stored for a longer period of time due to the chemical reaction that begins when the peroxide is added.
- the drying of a printed substrate can also be accelerated by using UV-drying background colors or hybrid UV systems instead of oxidative drying systems.
- Such inks are, however, significantly more expensive, often have sensitizing properties and, under certain circumstances, have poor overprintability. In addition, they only have a limited shelf life as a finished paint.
- innovative hybrid ink formulations that contain both conventional, oxidatively drying ink components and UV-curing ink components.

- Oxygen has two different excited states, both of which have a significantly higher energy than the ground state. In both states, the spins of the electrons are antiparal, contrary to Hund's rule.
- the more stable excited oxygen is also called singlet oxygen OO2) after the quantum mechanical term for this state.
- the two singlet states differ in whether the two electrons are in one (term symbol: a A g ) or both n * orbitals (term symbol: a Z g ).
- the 1 Z g state is energetically less favorable and changes very quickly to the 1 A g state.
- the 1 Z g state is diamagnetic, the energetically more stable one !
- the A g state shows due to the existing orbital moment (the quantum number corresponding to the projection of the orbital angular momentum onto the core-core connecting axis - symbolized by S, P, D etc. - has the value ⁇ 2 in the! A g state)
- Singlet oxygen can be formed in various ways: both photochemically from triplet oxygen and chemically from other oxygen compounds.
- a direct extraction from triplet oxygen by irradiation with electromagnetic radiation (eg light) is, however, excluded for quantum mechanical reasons, in the form of the selection rules for the emission or absorption of electromagnetic radiation.
- electromagnetic radiation eg light
- This form of oxygen is a powerful and selective oxidizing agent and is widely used in organic chemistry. In contrast to normal oxygen, it reacts with 1,3-dienes in a [4 + 2] cycloaddition to form peroxides. Singlet oxygen reacts with alkenes and alkynes in a [2 + 2] cycloaddition.
- the present invention is based on the knowledge that singlet oxygen is able to remove unsaturated double bonds, as they are in conventional len binders for background colors or intaglio printing inks can be used to network via an alpha-H abstraction. If a printing ink suitable for printing a (paper) substrate is mixed with photosensitizer and exposed to UV radiation immediately after printing, the drying of the ink is accelerated.

- an antimicrobial, for example antimycotic and / or antiviral and / or antibacterial, coating of a document of value substrate on the basis of a photo-induced generation of singlet oxygen by a photosensitizer is provided.
- singlet oxygen When exposed to (UV) light, singlet oxygen is released which, due to its reactivity, is able to kill bacteria, viruses and / or fungi in the immediate vicinity. Due to the high diffusibility of oxygen, it is not necessary that the photosensitizer is applied in close proximity to the bacteria, viruses and / or fungi, but the photosensitizer also acts at a distance of approx. 5 mm.
- a large area of a document of value such as a bank note can be given an antimicrobial, in particular antibacterial and / or antiviral and / or antimicotic finish. Furthermore, a subsequent overpainting can optionally take place, because singlet oxygen can also diffuse through a lacquer layer a few micrometers thick.
- the value document substrate according to the invention for example a security paper or a bank note, has a flat substrate which is at least partially provided with an antimicrobial coating containing the photosensitizer for generating singlet oxygen.
- the antimicrobial coating extends the service life of documents of value that are produced with the security paper according to the invention and reduces the risk of illness in people through the transmission of pathogenic microorganisms when they come into contact with documents of value of this type.
- Antimicrobial in the context of the present invention means that there is an activity against microorganisms, the effect ideally being a killing of the microorganisms, but also being able to consist in an inhibition of the growth and multiplication of the microorganisms.

- agents for combating microorganisms i.e. "antimicrobial agents” in the context of the invention therefore include in particular antibacterial, antifungal and antiviral agents, their action being both biocidal (for example bactericidal) and biostatic (for example bacteriostatic).
- the antimicrobial coating containing the photosensitizer for generating singlet oxygen can be single-layer or multilayer.
- the antimicrobial coating can, for example, be formed in two layers, whereby it is primarily the upper layer, ie the outer layer, which contains the photosensitizer for generating singlet oxygen, while the lower layer, ie the layer between the substrate and the upper layer, primarily establishes contact with the substrate.
- the photosensitizer for generating singlet oxygen can furthermore be a component of a (pre) coating or an ink acceptance layer of the document of value substrate.

- the banknote 9 was provided with an intaglio layer 12 by means of intaglio printing.
- the intaglio printing ink is based on a conventional, physically drying intaglio printing ink, which has as a further component a special photosensitizer for the generation of singlet oxygen.
- a 1,7-diaryl-1,6-heptadiene-3,5-dione derivative which is described in WO 2017/032892 A1 (see in particular the structures (40) to (63), (68 ), (69a), (69b) and (70) in claim 14 of WO 2017/032892 A1).
- the banknote 9 obtained showed, in the course of exposure to UV radiation during the drying of the intaglio printing layer 12, as a result of the presence of the photosensitizer for generating singlet oxygen, a greatly accelerated ink drying.
- a simultaneous printing machine suitable for printing with conventionally drying printing inks with a retrofitted UV drying system from IST Metz ("BLK-5", two lamps per side with a lamp power of 180 W / cm each) was used.
