Definitions
- the invention relates to a method for counterfeit-proof Marking of objects, such as bank cards, banknotes, Packaging and the like. It also relates to a tamper-proof Mark.
- an optochemical sensor is known. It is a chemically reactive on a metal layer Applied to a layer to be detected in contact with a Substance-containing solution changes its volume. On the chemically reactive layer is one of metallic clusters applied layer formed. By binding the to be proved Stoffs changes the distance between the from the Metallic clusters formed layer and the metal layer. At the same time, the absorption of on changes the light emitted by the sensor. The presence of the detected Stoffs causes a color change of the sensor.
- the known sensor is not suitable for forgery-proof Marking of objects. A color change only occurs an application of the liquid phase to the sensor on. In contact with moisture or liquids it can also come to a reaction which triggers a color signal or changed.
- the object of the invention is a method for marking of objects as well as to provide a marking which in a simple and cost effective way a high security against counterfeiting Offer.
- the further procedural solution allows for easy and cost-effective way of marking an invisible one Object.
- the marking is particularly forgery-proof. It can be obtained by contacting it with the coating coated according to the invention Substrate be made visible.
- the second layer is expediently in both methods structured applied.
- structuring it can a structure in the surface in the manner of a pattern or a drawing. It can also be about act a relief-like structure. In this case appears the mark in different colors.
- the fourth layer serves primarily the protection of the covered layers.

These materials are chemical essentially inert. They are insensitive to moisture.
- the function of the second layer is essentially in it, a predetermined distance to the third layer and / or permanently provide a predetermined structure.
- a dye forming the mark visible becomes.
- the coloring depends on the viewing angle and characteristic.
- the first layer by means of a Device for generating electromagnetic waves, preferably by means of LASER, fluorescent lamp, LED or xenon lamp, to be irradiated.
- the marker can with a device for determining the optical properties the electromagnetic reflected from the first layer Waves are identified. It can with the device for Determination of the optical properties of the absorption, preferably measured at different observation angles become. Such a determination of the optical properties allows a high security against counterfeiting.
- the layers at least partially by means of thin-film technology is / are made.
- vacuum coating technologies are used and the like. Into consideration.
- At least one of the layers of anisotropic material Refractive index is made.
- the second layer of an anisotropic refractive index material produced may be e.g. to act liquid crystal polymers, which under both Observation angles, i. Angles to the z-axis, as well as at different angles of rotation, i. angles in the x-y plane, show a characteristic coloring.
- At least one the layers are made of a material whose optical Properties targeted after applying the layer can be changed.
- the material may be e.g. to be a photosensitive polymer whose refractive index is changeable by irradiation with a suitable wavelength.
- a forgery-proof marking is provided for items such as check cards, banknotes and the like, provided, being on an electromagnetic associated with the object Waves reflective first layer one for Electromagnetic waves permeable, inert second layer is applied with a predetermined thickness, and wherein a third layer formed by metallic clusters on the second layer is applied.
- Such a mark is permanently visible; she is very tamper-proof.
- a tamper-proof Marking for items such as check cards, banknotes and the like.
- electromagnetic waves reflective first Layer a permeable to electromagnetic waves, inert second layer applied with a predetermined thickness is. - Such a mark is invisible.
- a third layer formed of metallic clusters is applied on a substrate so that they Visualization of the marking at a predetermined distance can be arranged to the first layer.
- the first layer can be be formed by the object itself.
- the second layer 3 has a structure on.
- the structure is here in the form of a relief, which e.g. designed in the manner of a bar code.
- the Dikke the second layer is preferably between 20 and 1000 nm. It is applied by means of thin-film technology. For this purpose, e.g. Vacuum coating process.
- the fourth Layer 5 protects the underlying layers from damage.
- the fourth layer 5 may as well as the second Layer 3 of a chemically inert and optically transparent Material, e.g. a metal oxide, nitrite, carbide or Be prepared polymer.
- the markings shown in Figs. 3 and 4 are only then visible when brought into contact with a substrate 6 on whose surface those from metallic clusters formed third layer 4 is applied.
- the third Layer 4 may be formed with one of first molecules be superimposed fifth layer 7.
- the fifth layer is 7 expediently formed from molecules which are added to the material are affine from which the second layer 3 made is. In a contact of the fifth layer 7 with the second Layer 3 thus comes to a specific adhesion. It can also be that the second layer 3 with another Fifth layer 7 is covered.
- the Fifth layers 7 are each formed of molecules that are related to each other have an affinity. It can be biopolymers act, which are complementary to each other.
- the fifth layer 7 can also be made of other polymers, silanes and / or structurally related compounds be.
- the substrate 6 is made of a transparent material, e.g. out Glass or plastic, made.
- a mark shown in Figs. 1 and 2 becomes this light the first layer 1 reflected.
- a light source such as a LASER
- a fluorescent tube or a xenon lamp a mark shown in Figs. 1 and 2 becomes this light the first layer 1 reflected.
- the reflected light has a characteristic spectrum.
- the mark appears coloured.
- the dependent on the irradiation or observation angle Coloring serves as a forgery proof for the Authenticity of the mark.
- the mark shown in Figs. 3 and 4 is merely the optically transparent formed second layer 3 on the electromagnetically reflective first layer 1 applied.
- the second layer 3 can be made of chemically inert materials, such as silicon oxide, carbide, nitrite, tin oxide or nitrite or of aluminum oxide or nitrite. The mark is not visible at first.
- optically transparent substrate 6 When applying the provided with the third layer 4 optically transparent substrate 6 may interact between the light reflected at the first layer 1 and the third layer. In turn, it creates one Color effect by, preferably made of glass Substrate 6, is observable.
- the third Layer 4 to be covered with a fifth layer 7.
- the substrate 6 At the Contact of the fifth layer 7 with the second layer 3 adheres the substrate 6 at the mark. It turns a given Distance between the third layer 4 and the first Layer 1 on.
- FIG. 5 of a marking according to FIG. 1 were measured by means of a UV / VIS spectrometer Lambda 25 of Perkin Elmer measured using a reflective insert. From Fig. 5 it can be seen that the longer wavelength peak with increasing viewing angle to shorter wavelengths shifts. Furthermore, a fixed peak is observed which is due to the silver clusters.
- Fig. 6 is a quantitative evaluation of the spectra according to Fig. 5 each shown at two different wavelengths. At the considered wavelengths is dependent on the Observation angle observed a change in absorption. The Absorption pattern is characteristic of the authenticity of the Mark.
