Definitions

  • the invention relates to a security element for increasing the counterfeit protection of security documents, such as banknotes, securities, identity cards, credit cards, debit cards or the like, the security element consisting of a substrate on which an imageable layer is arranged, the imageable layer having a volume hologram .
  • Security documents are equipped with optically variable security elements to protect against imitation, in particular with color copiers or other reproduction methods. Protection against counterfeiting is based on the fact that the optically variable effect that is visually, easily and clearly recognizable is not reproduced, or only insufficiently reproduced, by the above-mentioned reproduction devices.
  • Holograms and hologram-like lattice images as optically variable security elements in bank notes, in particular also in window bank notes, are known from the prior art. These holograms and hologram-like grating images can be present as light/dark transmission holograms or light/dark transmission gratings, surface structure holograms or surface structure gratings or volume holograms or Bragg gratings.
  • a volume hologram or Bragg grating is produced by exposing an exposable layer and is, for example, EP 2362275 A1 known.
  • the layer that can be exposed is several times as thick as the light wavelength.
  • a sequence of layer areas with different refractive indices is created in the exposable layer as a result of exposure and fixing, so that information in the volume hologram is in the form of a pattern, an alphanumeric character or a graphic image is stored.
  • the invention is based on the object of further developing a generic security element in such a way that protection against forgery is further increased.
  • an embossed layer is arranged on the substrate adjacent to the layer that can be exposed, and an embossed structure in the form of a refractive optical element is introduced into the surface of which that faces away from the substrate.
  • a coating is at least partially applied to the surface of the imageable layer that faces away from the substrate and to the embossing structure, the coating overlapping the imageable layer and the embossing structure and optically recognizable information in the form of a pattern, an alphanumeric character or a graphic Figure has.
  • the coating has at least one recess above the layer that can be exposed, so that the volume hologram is visible through the at least one recess and is not visible outside of the recess.
  • the coating can also have at least one recess above the embossed layer.
  • adjacent means that the imageable layer and the embossing layer are arranged next to one another on the same side of the substrate and are at least partially touching or are arranged so close together that an observer can observe them at a normal viewing distance of about 20 cm without optical aids, such as a magnifying glass, cannot see a distance between the imageable layer and the embossing layer. It is also possible for the exposure layer and the embossing layer to overlap in the area in which the exposure layer and the embossing layer adjoin one another. It only has to be ensured that there are areas in which the imageable layer and the embossing layer do not overlap and are arranged next to one another.
  • a particular advantage of the invention is that a security element is produced which is very difficult to forge and at the same time is very attractive because of the pronounced, bright and dynamic effects.
  • the high level of protection against counterfeiting results in particular from the fact that two areas of the security element that were produced using different technologies (volume hologram and embossed structures) are arranged next to one another. These are particularly preferably recognized by an observer together with the coating as a useful additional design element.
  • the layer that can be exposed to light consists of a photopolymer and/or the embossing layer consists of an embossing lacquer that is printed onto the substrate.
  • the coating consists of a single-layer or multi-layer structure.
  • the respective layers are arranged one above the other, viewed perpendicularly to the surface of the substrate.
  • a single-layer structure consists of a layer with a high refractive index, preferably a thin layer of zinc sulfide (ZnS). Also a layer of metal, a layer of thin metallic or metal-colored pigments that the Structure following the embossing structure, or a printing ink with effect pigments is possible.
  • the coating is preferably vapour-deposited or printed on.
  • a single-layer structure consists of a colored layer which contains platelet-shaped metallic particles whose longest edge length is 15 nm to 1000 nm and whose thickness is 2 nm to 100 nm, so that the colored layer has a metallic hue in incident light and a metallic hue in transmitted light colorful hue shows.
  • the platelet-shaped metallic particles preferably have a longest edge length of 15 nm to 600 nm and particularly preferably 20 nm to 500 nm and a thickness of 2 nm to 40 nm and particularly preferably 4 nm to 30 nm.
  • Such a color layer is, for example, from WO 2011/064162 A2 known and is also referred to as the gold-blue color.
  • a two-layer structure consists of two thin layers of different metals applied one on top of the other.
  • a three-layer structure consists of a first metallic layer and a second metallic layer, between which a dielectric layer is arranged.
  • such a three-layer structure consists of a reflection layer, a dielectric layer and a partially transparent layer, with the dielectric layer being arranged between the reflection layer and the partially transparent layer.
  • This Structure forms an interference-capable, multi-layer structure, as for example from the WO 2005/108110 A1 or the WO 2005/038136 A1 is known.
  • the viewer perceives a specific color that changes as the viewing angle changes. The viewer perceives a color shift effect when changing the viewing angle.
  • a multi-layer structure has at least two semi-transparent mirror layers and at least one dielectric layer arranged between the at least two mirror layers, as is the case, for example, from DE 10 2009 058 243 A1 is known.
  • the at least two semi-transparent mirror layers of the reflection layer are preferably formed from aluminum or an aluminum alloy, the dielectric spacer layer having a thickness h and a refractive index v fulfilling the relationship 120 nm ⁇ hv ⁇ 190 nm or from silver or a silver alloy, where the dielectric spacer layer with a thickness h and a refractive index v the relation 120 nm ⁇ hv ⁇ 170 nm or 340 nm ⁇ hv ⁇ 400 also referred to as gold-blue coating.
  • the embossed structure according to the invention is not a diffractive structure, such as a hologram.
  • the lateral dimensions of the respective individual embossed elements that form the embossed structure are therefore smaller or larger than the wavelength of visible light, in particular smaller than 300 nm or larger than 1 ⁇ m.
  • the embossed structure consists of a plurality of achromatic microstructure elements which have a lateral dimension of less than 1 mm, preferably between 3 ⁇ m and 100 ⁇ m.
  • the embossed structure consists of a combination of the structures mentioned above, it being possible for the structure types to be arranged next to one another, bordering, gridded, nested or also superimposed (substructures).
  • the structure types can be arranged next to one another, bordering, gridded, nested or also superimposed (substructures).
  • sinusoidal gratings can be present on a micromirror—or—moth-eye structures can be combined with diffractive structures.
  • the volume hologram is designed as a reflection hologram, which requires a dark/black absorber in the background, or as a transmission hologram in a transparent window area without any dark absorbers.
  • the volume hologram is designed to be single-colored or multi-colored or true-colored.
  • the volume hologram can have a color shift effect and could usefully supplement/combine an existing color shift effect of the multilayer coating.
  • the volume hologram can have a two-dimensional effect without a depth effect and/or a three-dimensional effect with a pronounced depth effect and/or dynamics when tilting.
  • the volume hologram can be designed as a transmission hologram, with information being able to be seen/read out using coherent light (laser).
  • the volume hologram can be designed as a white light reflection hologram.
  • An embossed structure can also serve as exposure master for the volume hologram, in a preferred embodiment the same embossed structure that is also used in the embossed layer, so that the same effects (color, dynamics, shape) can be seen in both areas.
  • a dark, preferably black absorber is required for better perception, which can be produced with a black body color, but also with a microstructure color, e.g. moth eye structures.
  • a reflecting reflector e.g. aluminium
  • the volume hologram can then be seen preferably outside the specular angle, i.e. when viewed from a very oblique angle.
  • the security element is applied as a film element in the form of strips or patches on a substrate (paper, polymer) or in a film/paper composite substrate or for embedding as a security thread in a substrate.
  • the film element can also be applied to or introduced into a polymer substrate with (“L element”) or without (“T element”) a carrier film.
  • the security element according to the invention can be combined with further machine-readable security elements.
  • one of the layers can contain one of the following elements or combinations thereof in some areas or over the entire surface: magnet, IR, UV, phosphor, THz.
  • the security element according to the invention can be combined with other printing and/or effect colors, such as super silver, gold color printing, Iriodin, colored ink.
  • the security element according to the invention can be designed as a window element with a different visual impression on two sides, particularly suitable as a window element, e.g. for polymer notes in a transparent area or for paper/foil composite banknotes in a window area.
  • the security element according to the invention can have hidden information ("varifeye effect").
  • the volume hologram is a reflection hologram and has no absorber in some areas in a transparent window.
  • the hidden message of the volume hologram can only be recognized when the volume hologram is placed on a dark/black background.
  • the volume hologram and the embossed layer are arranged in a window area so that they overlap at least in certain areas, so that a viewer from the front and back sees clearly different information or complementary motifs.
  • See-through occurs when the substrate is illuminated from one side and viewed from the other side.
  • Top view is when the illumination and viewing is from the same side of the substrate.
  • An optically variable element within the meaning of this invention is an element whose visual appearance changes when the element is tilted or rotated. For example, when the optically variable element is tilted or rotated, its color changes, a bar appears to move from one side of the element to another side, different characters are displayed when tilted or rotated, or there is a so-called pump effect in the form of an increasing or decreasing Outline of a subject.
  • the substrate of the security element according to the invention particularly preferably consists of a plastic film or of paper made of cotton fibers, such as is used for banknotes, or of other natural fibers or of synthetic fibers or a mixture of natural and synthetic fibers.
  • the substrate preferably consists of a combination of at least two different substrates arranged one above the other and connected to one another, a so-called hybrid.
  • the substrate consists, for example, of a combination of plastic film-paper-plastic film, i.e. a substrate made of paper is covered by a plastic film on each of its two sides, or of a combination of paper-plastic film-paper, i.e. a substrate made of a plastic film is covered on each of its covered with paper on both sides.
  • Documents of value for which a security element according to the invention can be used are, in particular, banknotes, stocks, bonds, certificates, vouchers, checks, high-quality entry tickets, but also other papers at risk of forgery, such as passports and other identification documents, and cards, such as credit or debit cards, whose card body has at least one layer of security paper, and also product security elements such as labels, seals, packaging, folding boxes, package inserts and the like.
  • the simplified term document of value includes all of the above materials, documents and product security means.
  • the coating which overlaps the imageable layer and the embossing structure, has optically recognizable information in the form of a pattern, an alphanumeric character or a graphic image.
  • Information within the meaning of this invention is a pattern-shaped and visually perceptible representation. This can, for example, form an alphanumeric string of digits and/or letters, a graphic image, an image, text or other characters.
  • the information particularly preferably consists of positive and/or negative motifs.
  • a motif element itself is applied to the exposeable layer and the embossed structure, whereas in the case of a negative motif the area surrounding the motif element is applied to the exposeable layer and the embossed structure.
  • a positive motif is, for example, a letter printed in dark color on the light-colored substrate.
  • a negative motif is, for example, a dark-colored area applied to the light-colored substrate, which has an unprinted area in the form of a letter within the area.
  • FIG. 1 shows a schematic of a security element according to the invention with a substrate 1, which consists for example of a transparent polymer film.
  • An imageable layer 2 with a volume hologram and an embossing layer 3 adjoining it are arranged on the substrate 1 .
  • the embossed layer 3 On its surface facing away from the substrate 1, the embossed layer 3 has a non-diffractive embossed structure, which in this example consists of a triangular structure with sloping flanks.
  • a coating 4 is applied to the embossed structure of the embossed layer 3, which has a gap 5 above the layer 2 that can be exposed to light.
  • An observer from the front or top side of the security element sees the volume hologram in the imageable layer 2 through the gap 5.
  • the coating 4 has optically recognizable information in the form of a pattern, an alphanumeric character or a graphic image, which is not shown in the figure.
  • the outline of the coating 4 or the recess 5 can form the information.
  • the coating 4 consists of a three-layer structure with the thin layers 4.1, 4.2 and 4.3.
  • layer 4.1 consists of a reflective material
  • layer 4.2 consists of a transparent dielectric
