- the coloring depends on the observation angle and is characteristic.
- the first layer can be irradiated by means of a device for generating electromagnetic waves, preferably by means of a LASER, fluorescent lamp, light-emitting diode or xenon lamp.
- the marking can be identified using a device for determining the optical properties of the electromagnetic waves reflected by the first layer. It can be set up with Determination of the optical properties of the absorption, preferably at different observation angles. Such a determination of the optical properties enables a high level of security against forgery.
- the layers are / are at least partially produced using thin-film technology.

- At least one of the layers is made of a material with an anisotropic refractive index.
- the second layer is preferably made of a material with an anisotropic refractive index.
- the material can e.g. are liquid crystal polymers which operate both at different viewing angles, i.e. Angles with respect to the z axis, as well as at different angles of rotation, i.e. Angles in the x-y plane, showing a characteristic color.
- At least one of the layers can be produced from a material whose optical properties can be changed in a targeted manner after the layer has been applied.
- the material can e.g. are a photosensitive polymer whose refractive index can be changed by irradiation with a suitable wavelength.
- a forgery-proof marking for objects such as check cards, banknotes and the like is also provided, an inert second layer having a predetermined thickness permeable to electromagnetic waves being applied to a first layer connected to the object and reflecting electromagnetic waves, and wherein a third layer formed of metallic clusters on the second layer is applied.
- Such a marking is permanently visible; it is very forgery-proof.
- a tamper-proof marking for objects such as check cards, bank notes and the like
- an inert second layer having a predetermined thickness permeable to electromagnetic waves and being permeable to electromagnetic waves connected to the object connected to the object is upset.
- Such a marking is invisible.
- the first layer can be formed by the object itself.
- a third layer formed from metallic clusters can be applied to a substrate in such a way that it can be arranged at a predetermined distance from the first layer in order to make the marking visible.
- FIG. 1 is a schematic cross-sectional view of a first permanently visible marking
- FIG. 2 shows a schematic cross-sectional view of a second permanently visible marking
- 3 shows a schematic cross-sectional view of a first marking, which is not always visible, and of a substrate suitable for visualization
- FIG. 4 shows a schematic cross-sectional view of a second marking, which is not always visible, and of a substrate suitable for visualization
- FIG. 5 Absorption spectra of a marking according to FIG. 1 under different observation angles
- FIG. 6 shows a quantitative evaluation of the spectra according to FIG. 5 at different wavelengths.
- a first layer which reflects electromagnetic waves is designated by 1. It can be a metal foil, e.g. an aluminum foil, act. However, the first layer 1 can also be a layer formed from clusters, which is applied to a carrier 2. The carrier 2 can be the object to be marked. The clusters are expediently made of gold. Likewise, the first layer 1 shown in FIGS. 1 and 3 can also be the object, provided that its surface is formed from a material reflecting electromagnetic waves.
- a chemically inert second layer 3 is applied to the first layer 1.
- the second layer 3 has a structure.
- the structure here is in the form of a relief, which is designed, for example, in the manner of a bar code.
- the thickness of the second layer is preferably between 20 and 1000 nm. It is applied by means of thin-layer technology. Vacuum coating processes are suitable for this.
- a third layer 4 made of metallic clusters is applied to the second layer 3.
- the third layer 4 is in turn overlaid by a fourth layer 5.
- the fourth layer 5 protects the layers below from damage.
- the fourth layer 5, like the second layer 3, can be made of a chemically inert and optically transparent material, for example a metal oxide, nitrite, carbide or polymer.
- the markings shown in FIGS. 3 and 4 are only visible when they are brought into contact with a substrate 6, on the surface of which the third layer 4 formed from metallic clusters is applied.
- the third layer 4 can be overlaid with a fifth layer 7 formed from first molecules.
- the fifth layer 7 is expediently formed from molecules which are affine to the material from which the second layer 3 is made. When the fifth layer 7 comes into contact with the second layer 3, specific adherence thus occurs. It may also be the case that the second layer 3 is covered by a further fifth layer 7.
- the fifth layers 7 are each formed from molecules which have an affinity for one another. These can be biopolymers that are complementary to one another.
- the fifth layer 7 can, however, also be made from other polymers, silanes and / or structurally related compounds.
- the substrate 6 is made of a transparent material, e.g. out
- the function of the marking is as follows: When light from a light source, such as a LASER, a fluorescent tube or a xenon lamp, is irradiated onto a marking shown in FIGS. 1 and 2, this light is reflected at the first layer 1. An interaction of the reflected light with the third layer 4 formed from the metallic clusters absorbs part of the incident light. The reflected light has a characteristic spectrum. The marking appears in color. The color, which depends on the angle of radiation or observation, serves as proof against forgery of the authenticity of the marking.
- a light source such as a LASER, a fluorescent tube or a xenon lamp
- the second layer 3 can consist of chemically inert materials, such as silicon oxide, carbide, nitrite, tin oxide or nitrite, or aluminum oxide or nitrite. The marking is initially not visible.
- the optically transparent substrate 6 provided with the third layer 4 When the optically transparent substrate 6 provided with the third layer 4 is applied, there may be an interaction between the light reflected on the first layer 1 and the third layer. In turn, a color effect arises which can be observed through the substrate 6, which is preferably made of glass.
- the third layer 4 In order to ensure that the predetermined distance between the first 1 and the third layer 4 required for producing the color effect is established, the third
- Layer 4 be covered with a fifth layer 7.
- the substrate 6 adheres to the marking.
- a predetermined distance is established between the third layer 4 and the first layer 1.
- the spectra of a marking according to FIG. 1 shown in FIG. 5 were measured by means of a Perkin Elmer Lambda 25 UV / VIS spectrometer using a reflection insert. It can be seen from FIG. 5 that the longer-wave peak shifts towards shorter wavelengths with increasing observation angle. A fixed peak can also be observed, which is due to the silver clusters.
- FIG. 6 shows a quantitative evaluation of the spectra according to FIG. 5 in each case at two different wavelengths. At the wavelengths under consideration, a changed absorption is observed depending on the observation angle. The absorption pattern is characteristic of the authenticity of the label.
