Definitions
- the invention relates generally to a security element with an excitation-dependent optical effect in the non-visible wavelength range, wherein the
- Excitation is not irradiation of light, as well as a method for verifying such a security element.
- the proposed security element comprises a recording material in which at least one volume hologram is stored, and at least two separately formed electrodes, to which a voltage can be applied and / or which can be charged, wherein the at least two electrodes and the recording material are formed and mutually are arranged, that when applying the voltage and / or an application of charges at least one local mechanical change, in particular deformation of the
- Recording material occurs, so that a reconstruction of the volume hologram is at least locally changed, wherein at least one elastic element between the recording material and one of the at least two electrodes is arranged.
- the document thus shows an electrically stimulable volume hologram.
- An electrical voltage can influence an optical effect.
- an occurrence of a disturbance of the reconstruction of the hologram is checked depending on the applied voltage.
- Printing inks are known from EP 2 463 11 1, the color impression of which is brought about via microparticles contained in one color, which are aligned with one another and arranged in a crystal structure.
- Wavelength can propagate only along certain directions or not at all in the crystal structure and is reflected accordingly. This causes a color impression due to the wavelength-selectively reflected light.
- a body color can be spoken of a structural color, since a geometric arrangement of the colloidal particles is responsible for the expression of the color. It is known to use such structural colors for the manufacture of objects whose color impression is easily changeable to a human observer.
- the invention is achieved by a security element having the features of patent claim 1 and a verification method having the features of patent claim 4.
- the invention is based on the idea of further developing the structural colors known from the prior art, which have an optical effect similar to that of a photonic crystal, and to provide security elements therewith, in particular for value or security documents.
- the properties of the colloidal particles are adjusted so that the optical interaction in the
- Wavelength range occurs.
- a size of the colloidal nanoparticles is adjusted, so that when forming a suitable electrical or
- the security element is machine-readable and not visually recognizable. Counterfeiters easily “overlook” such "hidden” security elements that are not immediately visible, so that counterfeiting is due to the absence of the corresponding security elements
- Entities having at least one security feature are called
- any physically trained object that includes at least one security feature is a security element.
- Security documents include i.a. Badges, driving licenses, identity cards, but also banknotes, postage stamps, visas and fake labels and cigarettes, tickets or the like.
- Value documents are security documents to which a value is assigned, e.g.
- Pigments which show emission of light as a result of excitation are referred to as luminescent pigments.
- the emission caused by the excitation is referred to as luminescence, the excitation as luminescence excitation.
- a preparation that can be used to print information is also referred to as ink or ink.
- a preparation whose color impression produced in the printed condition is caused by pigments absorbing certain wavelengths of light independently of environmental conditions and / or excitation and / or
- body colors remit / reflect are called body colors.
- a color of light is determined by a wavelength of light.
- a color is also called spectral color, as this is in the decomposition of a radiation which has light of a continuous wavelength spectrum in wavelength-selective
- the visible wavelength range only covers the wavelength of about 380 nm to 780 nm, ie only wavelengths from this range cause a color impression in a human observer, it is assumed here that also light in the UV wavelength range with wavelengths less than 380 nm or in the IR Wavelength range with wavelengths greater than 780 nm has a color that corresponds to the respective wavelength.
- the non-visible wavelength range includes UV light with wavelengths below 380 nm and IR light with wavelengths greater than 780 nm.
- the decisive factor is that light from these wavelengths is optically imperceptible to humans.
- Particularly preferred wavelength ranges of the invisible wavelength range include the wavelengths 190 nm to 380 nm and 780 nm to 1100 nm.
- the light of these preferred ranges can be easily detected with silicon-based semiconductor detectors.
- CMOS and CCD sensors can be used for the detection of non-visible light in the preferred wavelength ranges between 190 nm and 380 nm or 780 nm and 1100 nm.
- white light is here considered an electromagnetic broadband radiation with a continuous wavelength spectrum, which includes the infrared
- Wavelength range and the UV wavelength range includes.
- printing preparations which are structural inks.
- printing preparations comprising a plurality of nano- or microparticles having electrical or magnetic properties which are arranged in an electric or magnetic field relative to each other in a crystal-like regular structure.
- the crystal-like structures can be photonic crystals.
- a photonic crystal is a regular periodic structure that promotes or suppresses light propagation for single or multiple wavelengths due to quantum mechanical effects. This creates a color impression of the corresponding photonic crystal.
- Structural inks which have a changed color impression upon excitation are likewise described in EP 2 463 11 1 A2. These may be designed such that the printing preparation comprises microcapsules which are a substrate or medium
- the colloidal particles may be, for example, charged particles comprising, for example, aluminum, copper, silver, tin, titanium, tungsten, zirconium, zinc, silicon, iron, nickel, goblin or the like.
- the particles may further comprise a substance having a
- Polymer material includes, for example, polystyrene (PS), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), etc.
- PS polystyrene
- PE polyethylene
- PP polypropylene
- PVC polyvinyl chloride
- PET polyethylene terephthalate
- Embodiments may charge uncharged particles with a charged material.
- particles may be coated with metal inorganic oxides such as silicon oxide SiO x , titanium oxide TiO x , etc. But also with polymer materials
- Coated particles coated with ion exchange resins and many more can be used.
- EP 2 463 1 1 1 A2 a variety of exemplary
- magnetic field are present.
- this is understood to mean the absence of an externally specifically set electric or magnetic field.
- a field caused by magnetic particles or electrically charged particles intrinsically present in an article is left unattended.
- the magnetic field strength caused by the earth's magnetic field is considered to be insignificant, so that a space is field-free despite the existing geomagnetic field, if no additional magnetic field is present in the room.
- this field is not considered intrinsic.
- the space is considered to be field-free when no electric field is present, even if, for example, a magnetic field is applied to affect a magnetorheological fluid in the room in terms of its viscosity.
- the space is field-free if there is no "external" magnetic field with a field strength in the space that is greater than the field strength of the earth's magnetic field.
- Structure excitation in the structure color causes an influence of light having the wavelength ⁇ .
- press ⁇ indicates that the structure excitation causes the structure color to influence light in the UV range.
- Printing inks or inks which, in the case of a luminescence excitation, in particular an irradiation of UV light, emit an emission of light, i. a
- Luminescence show, are referred to as luminescent.
- a security structure formed on the substrate layer which is formed with a structure color comprising microcapsules in which colloidal particles are arranged, which can be arranged in a crystal-like structure by means of a structure excitation, which comprises forming an electric and / or magnetic field, or / and umordenbar, wherein the crystal-like structure on the structure excitation influenceable and / or adjustable reflection and / or transmission properties has for light, the microcapsules in the non-structure excited state for at least one wavelength in the non-visible wavelength range increased transmittance and reduced reflectivity and the microcapsules in the structure-excited state, in which an electrical and / or a magnetic field generated via the structure excitation exist in the region of the microcapsules, in comparison to the non-structurally excited state a reduced one
- Structure color comprises microcapsules in which colloidal particles are contained, which by means of a structure excitation, which forming an electrical or / and magnetic field comprises, can be arranged to each other in a crystal-like structure and / or can be reorganized, wherein the crystal-like structure on the structure excitation influenceable and / or adjustable reflection and / or transmission properties for light, comprising the steps:
- Wavelength range lies on the security element while the
- Security element is in the structure-stimulated state
- Security element is in the structure-stimulated state
- Verification can be easily performed with a suitable light source emitting light in the non-visible wavelength region and a detection device which can detect light of the corresponding wavelength, and a detection device
- a small proportion of the irradiated light intensity can be selected, since reflection of light in the non-visible wavelength range on a physically formed security element or security document generally does not take place. For example, a value of 10% of the irradiated intensity can be assumed for the expected reflection. However, a value of 30%, 50% or even 80% can be set. This depends inter alia on the layer thickness of the security structure, i. the printed structure color amount per area and the concentration of the microcapsules in the structure color.
- a transmission value of 70% or 50% or even 30% can be set.
- a much more reliable verification makes possible an embodiment in which additionally the non-structure-excited state of the security element is brought about, and while the security element is in the nonstructured state, light with the one wavelength is irradiated on the security element and while the security element in the not -structured state, the intensity of the light reflected at the security element of the one wavelength is detected and / or the intensity of the light transmitted through the security element of the one wavelength is detected,
- the reflected intensity detected in the non-pattern excited state is used as the expected reflection intensity and / or the transmitted intensity detected in the non-pattern excited state is used as the expected transmission intensity, and the security element is verified as genuine only when the reflected intensity detected in the structure-excited state is greater than the expected reflection intensity and / or the transmitted intensity detected in the structure-excited state is smaller than the expected transmission intensity.
- the effect of the pattern excitation on the interaction with the invisible light is clearly demonstrated.
- Room area in which the security element is located This can be done for example by interrupting a current flow through a coil or other inductance, which generates a magnetic field in the region of the security feature as a structure excitation. Otherwise, alternatively or additionally, a voltage may be set to zero to "remove" an electric field caused by one or two electrodes.
- Embodiment generating a magnetic and / or electric field in the space area in which the security element is located. Electrodes may be disposed adjacent to the space such that upon application of a voltage, an electric field is generated in the security element and in the microcapsules. In some embodiments, the electrodes are already disposed and integrated in a security document adjacent to the security element. By applying a voltage to contacts connected to the electrodes, an electric field can then be generated reliably.
- a magnetic field can be generated via a coil structure. For example, spiral-shaped conductor structures can be formed in a security document surrounding the security element. A current can then be fed into the helical conductive structure via contacts guided on a surface of the security document, which generates a magnetic field.
- the electrical and / or magnetic field can also be generated via external structures not coupled to the security element.
- the magnetic field for example, by means of an approximation of a permanent magnet to the
- Security element can be increased. By removing the permanent magnet, field freedom can be generated in the security element. Particularly preferred are magnets in mobile phones, as they generate strong magnetic fields for the comparatively compact design and are available everywhere and available.
- a wavelength in the UV wavelength range is selected as the one wavelength and irradiated upon irradiation of light of one wavelength UV light.
- the security element the structure color in the non-structure-excited state, the increased transmissivity and reduced reflectivity for at least one wavelength in the UV wavelength range and exists in the structure-excited state, the reduced transmissivity and the increased reflectivity for this at least one wavelength in the UV wavelength range.

- a filter is between the security element and the
- Photoluminescence caused by UV or IR radiation can then be distinguished from the reflection of UV or IR radiation.
- the luminescent light is blocked by the filter and so can not falsify the transmission or reflection measurement.
- such a selection is advantageous in order to distinguish the carried out UV or IR reflection of a triggered luminescence.
- an electrical and / or magnetic field strength is changed in the spatial area in which the security element is located while the excited state is brought about, and the intensity of the light of the one wavelength reflected and / or detected at the security element is detected the intensity of the light transmitted through the security element of the one wavelength is repeatedly performed and a dependence of the detected intensities of the reflected light of a wavelength of the electric and / or magnetic field strength with an expected reflection intensity dependence and / or a dependence of the detected Intensities of the transmitted light of a wavelength of the electric and / or magnetic field strength in each case with an expected
- an angle in the range between 10 ° and 40 °, measured against a surface normal of the substrate of the security element, is preferably selected.

- FIG. 8 is a schematic flow diagram of a verification method.
- Microcapsules 10 included. The same technical features are provided in the figures with the same reference numerals.
- a structural ink contains a large number of such microcapsules, which are responsible for the color impression or the color of the structure color.
- Each of the microcapsules 10 has a shell 11 containing a transparent substance 12 containing colloidal particles, e.g. Nanoparticles 13, includes.
- the sheath 1 1 is formed of a transparent material.
- the substance 12 is also transparent and represents a fluid in which the nanoparticles 13 in the
- Embodiments of Fig. 1 a to 1 c, 2a to 2c can move.
- the nanoparticles are, for example, clusters of iron oxide with a charged layer or else
- Embodiments may also be paramagnetic particles.
- the substances contained therein and the nanoparticles reference is made in particular to EP 2 463 11 1 A2.
- structural inks containing such microcapsules and resulting in visible wavelength range dyeing are also available from Nanobrick, Gyeonggi-do, Korea.
- the colloidal nanoparticles in the field-free space which is shown in Fig. 1 a, arranged irregularly.
- the microcapsules 10 of the colloidal nanoparticles have no special optical property, so that they do not significantly influence the color impression of the structure color in which they are contained. This can thus be regarded, for example, as almost transparent in the printed state. If an electric field with a field strength E1 is applied, the charged nanoparticles align themselves to form a lattice-like crystal structure 15. This is shown in FIGS. 1 b and 1 c. Since the nanoparticles themselves carry a charge, this leads to a repulsion between them.
- a ratio of the electric field strength E1 or E2 to the own repulsion due to the charge determines a lattice spacing of the nanoparticles. Another factor is the Particle size. If an interaction with light of a wavelength in the UV wavelength range is to be brought about, the particle size must be selected to be correspondingly small.
- the crystal structure thus formed has characteristics of a photonic crystal. In this, for some wavelengths, propagation is only along certain
- FIGS. 2a to 2c another embodiment of microcapsules 10 is shown schematically. These differ in that the colloidal particles already in the field-free space in the microcapsule 10 have a crystal structure 15, so that from the white light of a black body beam, for example, a color component of the far infrared (FIR) is reflected. As the field strength increases, the distance between the particles in the crystal lattice decreases, so that a near infrared (NIR) color component is now reflected. If the field strength is further increased (FIG. 2c), the grid spacing becomes even smaller, so that again a color component of the near infrared (NIR) is reflected again.

- Covering layer 180 arranged, which for both light in the non-visible
- Wavelength range is transparent.
- the substrate layers 160 may be transparent or opaque or, for example, only in the region in which the surface 165 is printed with the structure color 210, a transparent window for the light from the non-visible wavelength range.
- FIG. 4a shows on the left a schematic sectional drawing of a security document 100 with a security feature 110.
- the security element 110 includes a security structure 15, which is printed with a structure color 210 on a surface 165 of a substrate layer 160.

If, for example, the security element in the structurally excited state is to reflect light with a wavelength in the UV wavelength range, for example at 254 nm, then it is advantageous if at least the materials of the security document 100 except for the structure color 210 for light of the non-visible Wavelength, for example, for 254 nm, are transparent. In the non-structure excited state, the structure color 210 and thus the entire security element 1 10 is transparent to UV light with the wavelength 254 nm. In the illustrated embodiment, the entire Security document for the non-visible wavelength, here for example 254 nm, transparent.
- the security document 100 and the security element 1 10 are in the situation shown in Fig. 4a in the non-structural state excited.

- the detection means may further alternatively or additionally comprise a conversion layer which converts incident light 121 of one non-visible wavelength into light 331 of another wavelength, preferably in the visible wavelength range.
- the conversion layer may comprise a luminescent color with luminescent pigments. If, as in the example described, UV light of wavelength 254 nm is to be detected, then the reflected UV light 121 can be converted into light 331 in the visible wavelength range. This can be detected and evaluated by the human eye or a camera, for example a CCD-based camera.

- structure-inspired state of the structure color 210 of the security structure 1 15 is detected.
- the shape "A" of the security structure 15 can be recognized as negative, ie, the lateral shape of the structure color 210 printed on the surface 165 of the substrate layer 160 can be recognized as a dark area against a light background of the transmitted UV light 122
- the structure color 210 prevents in
- the security element can be designed to interact with IR light.

- FIGS. 5a to 5e show the situation of FIGS. 4a and 4b for a sequence in which the intensity of the structure excitation is increased, for example the electric field strength. Measurements in reflection and in transmission are carried out for different excitation intensities. The respective detected intensities of the reflected non-visible light and the transmitted non-visible light are respectively shown in a spatially resolved representation.

- FIG. 5b From an excitation intensity, which is shown in FIG. 5b, for example, 30% of the incident light is reflected with the non-visible wavelength. The transmission decreases to 70%. If the excitation intensity is further increased, as shown in FIG. 5 c, the reflection increases to approximately 90% and the transmission decreases to approximately 10%.
- FIG. 5d illustrates the situation in which the maximum reflection of the incident light with the non-visible wavelength takes place, for example ideally a reflection of 100%. The transmission then drops to 0%.
- the reflection intensity and the transmission intensity are for a place of
- Structure excitation intensity and a dependence of the transmission intensity on the structure excitation intensity can likewise be used to verify the security element. Only if the structure color is identical in its properties to a structure color with which authentic security elements are manufactured, the same dependence of the reflection or transmission results for the light of a selected wavelength length in the non-visible wavelength range, as expected becomes.

- Security element must be exceeded. The same applies to the transmission, wherein the transmitted intensity detected in the structure-excited state must fall below a transmission intensity derived from the detected intensity of the non-structure-excited state in order to be able to verify the security element as genuine.

It can also be applied to measurements in the non-structural state at all simple embodiments are dispensed with and a value can be specified as reflection intensity, which must be exceeded in the structure-stimulated state. The same applies to the transmission intensity to be undercut.
