Definitions
- the invention relates to feature substances for authenticity assurance of value documents, methods for their production, security elements and value documents which contain the feature substance according to the invention, as well as methods for the authenticity assurance of security elements and value documents using the feature substance according to the invention.
- the feature substances according to the invention contain both at least one luminescent substance and at least one further substance, which is preferably magnetically or electrically conductive.
- Security elements in the sense of the present invention are elements with authenticity features which are applied to a value document for authenticity assurance or introduced into a value document.
- Documents of value within the scope of the invention are items such as banknotes, checks, stocks, tokens, identity cards, passports, credit cards, documents and other documents, labels, seals, and items to be protected, such as CDs, packaging and the like.
- the preferred application is banknotes.
- the authenticity assurance of value documents by means of luminescent substances has long been known. Preference is given to using rare earth-doped host lattices, wherein the absorption and emission ranges can be varied within a wide range by suitable tuning of rare earth metal and host lattice.
- the use of magnetic and electrically conductive materials for authenticity assurance is known per se. Magnetism, electrical conductivity and luminescence emission are mechanically detectable by commercially available measuring devices, and luminescence is also visual in sufficient intensity when emitted in the visible range. Practically as old as the authenticity assurance of value documents is the problem of forgery of the authenticity features of the value documents.
- the security against counterfeiting can be increased, for example, by using not only one feature substance but several feature substances in combination, for example a luminescent substance and a magnetic substance, or a luminescent substance and a substance influencing the luminescence properties.
- feature substances are provided in the form of a specific pattern, for example form a luminescent coding
- the feature substance combination should preferably also be able to be provided by methods other than printing in the form of a pattern on or in a value document or security element.
- the object of the present invention is, moreover, a
- the feature substance combination according to the invention has at least one luminescent substance which can be excited by radiation in the infrared and / or visible and / or ultraviolet region for luminescence emission, preferably fluorescence emission.
- the combination of feature substances according to the invention has nanoparticles which are bound by adhesive forces to the surfaces of the luminescent substance particles. The adhesion is sufficiently strong that during storage and processing no separation of luminescent substance and nanoparticles occurs, at least not in a disturbing for the production of security features extent. Even when stored as a dispersion no segregation is to be feared.
- the combination of feature substances according to the invention is a "composite feature substance", which, although composed of at least two different substances, behaves like a single feature substance.
- the properties of the composite feature substance represent a combination of the properties of the luminescent substance and the nanoparticles
- a “combination” can be a purely additive combination and / or an influence on the properties.
- the invention utilizes a phenomenon which is used in a similar way for the stabilization of emulsions and in the suspension polymerization.
- the first prerequisite for the principle of action as a Pickering emulsifier is that the emulsifier is insoluble in the liquid phase and is substantially smaller than the suspension particle to be stabilized Ine suitable interaction force, ie adhesion between the zu stabilizing suspension particles and the Pickering emulsifier, but at the same time also a sufficiently good wettability of the Pickering emulsifier with the surrounding liquid.
- luminescent substance particles are coated with nanoparticles, whereby a nanoparticle monolayer, in which the nanoparticles form a dense packing, typically arises. But even a partial, preferably extensive, envelope may be sufficient.
- the luminescent substance particles have an average particle size of about 1 to 100 ⁇ m.
- the volumes of the nanoparticles are at least one order of magnitude, preferably by 2 to 3 orders of magnitude, less than the volumes of the luminescent substance particles.
- the feature substance according to the invention is therefore actually a system of feature substances whose properties result from the combination of the properties of the individual components.
- Luminescent substances are not limited in any way. In principle, all substances, in particular luminescent substances, which can be excited by irradiation with light in the infrared and / or visible and / or ultraviolet range for emission, in particular luminescence emission, are suitable. The emission or luminescence emission takes place preferably also in the infrared and / or visible and / or ultraviolet region. The luminescent substances are preferably fluorescent substances.
- suitable luminescent rare earth-doped host lattice for example, with ytterbium, praseodymium, neodymium, etc. doped garnets or perovskites may be mentioned, and mineral phosphors such as sulfides, oxides, selenides with traces of heavy metals such. As silver, copper, manganese or europium are suitable. However, these examples are intended as a guide only and should not be construed as limiting. Furthermore, organic luminescent substances can also be used, for example rhodamines, perylenes, isoindolinones, quinophthalones and oxazinones.
- Luminescent substances are also commercially available, for example Paliosecure Yellow from BASF, and Cartax from Clariant.
- Substances which modify the luminescence properties of the luminescent substance are, for example, those which absorb in certain wavelength ranges in which the luminescent substance emits and thus change the luminescence spectrum.
- An example of such a combination is Example 9 from the above-mentioned WO 81/03508 A1 as luminescent substance and nanoscale Fe 3 ⁇ 4 as nanoparticle substance.
- luminescent substances can also be used as nanoparticles, ie in principle the same substances which are also suitable for forming the core of the feature substance according to the invention.
- a combination of different luminescent substances results in a heterodyne luminescence spectrum.
- nanoparticle sheath it is preferred to use substances which have a machine-detectable property which differs from the detectable property of the core material, for example magnetic or magnetizable substances, electrically conductive substances and semiconductors. These substances must be stable in the application medium; For example, nanoscale iron is unstable in water, but after wetting with water, it transforms into an indefinable magnetic oxide (nanoscale metals are usually pyrophoric). When choosing the materials, it should be noted that they are not in areas that are important for the identification of the material
- Luminescence are essential, strong absorption.
- the luminescence spectrum must not be affected by the nanoparticles to a disturbing extent. How strong a change may be so as not to be perceived as a disturbing impairment, depends essentially on the intended application. In some cases, a change or weakening of the luminescence spectrum and / or absorption spectrum may well be desirable to make identification more difficult.
- CNTs carbon nanotubes
- CNTs are microscopic tubular carbon structures. In the walls of the tubes, the carbon is sp 2 -hybridized and forms honeycombs as in the planes of graphite.
- the diameter of the tubes is usually in the range of 1 to 50 nm, but smaller tubes can be made.
- the lengths of each tube can be up to be several millimeters.
- SWCNTs single-walled carbon nanotubes
- MWCNT multi-walled carbon nanotubes
- the electrical conductivity within a tube may be metallic or semiconducting.
- CNTs are commercially available (eg from MER Corporation or NanoLab Inc.) and can be sized to size by conventional crushing techniques such as milling.
- nanoparticle materials which can be combined with luminescent substances to feature substances according to the invention are nano- ⁇ -iron, nano-Fe 3 O 4 and nano-NiFe 2 O 4.
- the feature substances with nano- ⁇ -iron, nano-Fe3 ⁇ 4 and nano-NiFe 2 ⁇ 4 are luminescent and magnetic.
- Example 9 above cited WO 81/03508 A1 as a luminescent substance, with
- MWCNT particle size 20-50 nm
- MWCNT particle size 20-30 nm
- MWCNT particle size 40-70 nm
- nano- ⁇ -iron APS 25 nm
- nano-Fe 3 O 4 APS 20-30 nm
- nano-NiFe 2 O 4 APS 20-30 nm
- APS refers to the diameter of the carbon tubes.
- the materials are available, for example, from MER Corporation.
- the average particle sizes of the nanopowders can range from about 1 to 1000 nm, the optimum particle sizes also depending on the size of the Depend on luminescent substance particles.
- the luminescent substance particles typically have mean particle sizes in the range from about 1 to 100 ⁇ m, and the nanoparticles are smaller by at least 1, preferably 2 to 3, orders of magnitude.
- Preferred average particle sizes for the nanopowders are in the range from 1 to 500 nm, more preferably 10 to 100 nm.
- the weight ratios of luminescent substance and nanoparticle material depend on the type and particle size of the materials. In addition, they depend on the exact nature of the desired feature substance, i. That is, whether a feature substance is desired whose luminescent substance particles are optimally surrounded by a nanoparticle coating, whether a partial coating is also considered sufficient, or whether, if appropriate, free (uncoated) luminescent substance particles or free nanoparticles should also be present. If a feature substance is desired that is composed of luminescent substance particles enveloped as completely as possible by nanoparticles, but contains no free luminescent substance particles and no free nanoparticles, the weight ratio of luminescent substance to nanopowder is typically approximately in the range of 1: 1.
- the weight ratios can also vary within a substantially broader range, for example from 100: 1 to 1: 100, preferably from about 5: 1 to 1: 3, in particular when the feature substance according to the invention contains additional free luminescent substances and / or nanoparticles. For such additives, it must be tested by previous tests whether the system obtained is stable against segregation.
- the feature substance according to the invention is not limited to combinations of one type of luminescent substance with one type of nanoparticle. Rather, 2 or more different luminescent substances and / or 2 or more different nanoparticles can be combined with one another. In this way, one obtains a luminescent substance which is also magnetically and electrically conductive.
- Luminescence properties, magnetic properties and electrical conductivity properties of the individual feature substances are detected.
- the required spectrometers, luminescence or magnetism controllers, and conductivity meters are commercially available.
- the preparation of a feature substance according to the invention is carried out in a very simple manner by adding the luminescent substance or substances and a material in the form of a nanopowder, or optionally several different nanopowder materials, to a dispersion medium and stirring them together until a dispersion is obtained.
- the dispersion may be used as such, but preferably the feature substance is separated from the dispersion, usually by filtration, and dried.
- the dispersant used is preferably water.
- the dispersed nanoparticles are not retained during filtration by conventional standard filters. Their retention is possible through special filters. So if you want to produce a feature substance that consists of luminescent particles whose surfaces are coated as completely as possible with nanoparticles, but no free nanoparticles should be present, the production can be done in a simple manner by using a significant excess amount of nanopowder, stirred for a sufficient time (about 10 hours) and then filtered. Nanoparticles that are not bound in the form of a coating of luminescent material particles pass through the filter or, depending on the density, float on the dispersion while the feature substance sinks and later remains on the filter.
- the feature substances according to the invention are both in terms of their properties (luminescence, magnetism, electrical conductivity) as well as their appearance, such. B. their color, mixed products from the
- a white or colorless luminescent substance is coated with a black or a brown nanopowder, a homogeneous feature substance powder with a gray or light brown color results.
- the feature substance according to the invention is used for authenticity assurance of value documents or security elements.
- Value documents and security elements each consist of at least one layer of carrier material and optionally further layers. In addition, they have at least one authenticity feature which is formed by one or more feature substances. In contrast to a value document, a security element is not marketed as such but in connection with a value document to which it is applied or incorporated.
- the security elements and value documents according to the invention have at least one authenticity feature which is formed by a feature substance according to the invention.
- the feature substance according to the invention does not differ from conventional luminescent substances. It can be introduced, for example, in the volume or in subregions of the volume of a security element or value document, wherein the carrier material may consist of paper or plastic. Alternatively, the feature substance may be provided in the form of a coating on at least one surface or on portions of at least one surface of a security element or value document.
- the feature substance may be contained in a printing ink which is printed on a security element or document of value.
- the feature substance of the invention is used in each case in concentrations, as are customary in the respective field of application for luminescent substances, ie about 0.05 to 1 wt.%, When the feature substance in the volume of a Paper layer is included, and about 10 to 40 wt.%, When the feature substance is contained in a printing ink.
- Security elements with the feature substance according to the invention are preferably security threads, mottling fibers, planchettes and labels, which are introduced into the volume of a value-document carrier material or glued to a surface of the carrier material or another layer of a value document.
- Feature Substance are rubbed example, in a paint, which is then pulled out to a paint film and cut to a suitable size for a security element.
- a suitable varnish is a polyamide varnish and suitable concentrations are in the range of about 0.1 to 1 wt%.
- a particular advantage of the feature substances according to the invention becomes apparent when a feature substance according to the invention is intended to be provided in a defined distribution, for example when the feature substance is to form a code. In such a code, areas of high concentration of feature substance switch to areas of low concentration
- Feature substance or without any feature substance in a predetermined manner can be read out by machine. So far, such codes could only be produced by printing luminescent substances in a specific pattern. They could not be formed directly in the volume of a value document.
- the feature substances according to the invention have the peculiarity that they not only have luminescence properties, but are preferably also magnetic or magnetizable or electrically conductive.
- the nanoparticles of the envelope of the luminescent substance particles align in the field, and the feature substance has a tendency to migrate in the field.
- the prerequisite for such an orientation and, if appropriate, migration is that the surrounding medium of the feature substance is sufficiently fluid to produce a
- the feature substance according to the invention can be aligned or moved in a desired manner in a carrier material or a printing ink by applying a suitable magnetic or electric field, as long as the carrier material still sufficiently soft or moist, or the ink still sufficiently liquid is.
- a pattern of regions of high concentration of feature substance and regions of low concentration of feature substance in a paper layer can be produced, for example, by introducing a feature substance according to the invention having luminescent and magnetic properties in the paper machine into the moist paper, while an arrangement of Magnet is located in the desired code pattern.
- the magnetic nanoparticles of the feature substance then align themselves in the moist paper pulp, and the feature substance particles migrate to the magnets, reproducing the arrangement pattern of the magnets, ie the code.
- the code can be z. B. be read spectrometrically.
- Example 9 2 g of the above-mentioned Example 9 from WO 81/03508 A1, and 1.5 g of MWCNT nanopowder are weighed into a beaker containing about 50 ml of water and stirred for one day at room temperature. At the beginning of the mixing process, the nanopowder floats and sometimes forms large lumps. After the sparingly dispersible nanopowder is finely dispersed in the resulting dispersion, the material is filtered. There is no filter breakthrough of the nano-material through the filter pores. The filtered material is dried at 110 ° C, for example, overnight.
- the material can be rubbed into a polyamide varnish and the varnish can be drawn off to a varnish film, wherein the concentration of feature substance is also, for example, 0.4% by weight.
- the paint film is suitable for sticking on banknotes.
- the authenticity of the banknote can now be verified both by measuring the infrared luminescence and by measuring the electrical conductivity that is caused by the nanopowder. Of course, the authenticity can also be determined by measuring both properties.
- nanopowders mentioned above in connection with WO 81/03508 A1 can also be used.
- other luminescent substances can be used.
