Definitions
- the invention relates to a document of value, comprising a document of value substrate having a perforation area with a front side and a rear side, the front side of the document of value substrate being provided with a film security element at least in the area of the perforation of the document of value substrate;
- the value-document substrate perforation area can be seen when viewing the back of the value-document substrate in incident light and is formed in the form of a first motif consisting of a first partial area and a second partial area;
- the foil security element has a transparent area, which is formed in the first partial area of the value document substrate perforation area, and has a non-transparent area, which is arranged overlapping the second partial area of the value document substrate perforation area;
- the transparent area of the film security element formed in the first partial area of the value-document substrate perforation area can be seen in incident light in the form of a second motif when the front side of the value-document substrate is viewed;
- the non-transparent area of the film security element arranged to
- a value document according to the invention can be, for example, banknotes or identification documents, but also stocks, certificates, stamps, checks, tickets, tickets, airline tickets, ID cards, visa stickers or the like, as well as labels, seals, packaging or other elements.
- the simplified designation "document of value” therefore always includes documents of the type mentioned.
- the term document of value also includes security paper for the production of banknotes.
- documents of value are generally equipped with security elements which allow the authenticity of the document of value to be checked and which at the same time serve as protection against unauthorized reproduction of the document of value.
- Foil security elements for example, come into consideration as security elements, which have a foil substrate or plastic substrate and are applied to the value document substrate by means of an adhesive layer.
- the WO 95/10420 A1 describes a document of value in which the carrier is provided with a window-like opening which is closed with a covering film which is transparent at least in some areas, the covering film being able to be provided with additional security features, for example diffraction structures, particularly in the region of the window-like opening.
- the WO 2005/025891 A2 describes a data carrier with a foil security element, both the foil security element and the data carrier having a perforation area; the perforation areas preferably overlap at least partially and particularly preferably they are congruent.
- the perforation area in the data carrier is covered with a further film on the side facing away from the data carrier side carrying the film security element.
- the WO 2010/000432 A1 describes a document of value with an opening which is closed on one side with a translucent film.
- a translucent coating which is preferably implemented over the entire surface.
- the coatings are each independently extruded or laminated.
- the WO 2011/015622 A1 describes a document of value with an opening which is closed on one side with an at least partially translucent or transparent film, there being a coating on the side of the document of value opposite the film in the area of the opening and essentially in the area of the film surface, with the coating inside the Opening does not exist or essentially does not exist.
- the WO 2014/108329 A1 describes a method for producing an endless paper web for the production of security and valuable documents.
- the paper web is first provided with a continuous opening.
- a film with security features to be applied to the paper web is then applied in register.
- the WO 2016/091381 A1 describes a bank note with a transparent window area which is provided with a security element.
- the security element includes a carrier and one on the carrier arranged layer structure, comprising a reflective layer, which is arranged on the carrier by means of an embossed lacquer layer with an embossed relief structure, a colored thin-layer element and a transparent adhesive layer, the reflective layer being obtainable by printing and based on platelet-shaped metal pigments which are constituted in such a way that they are three-dimensional Align along the relief structure of the embossing lacquer layer.
- the embossing lacquer layer with an embossed relief structure is provided with the reflection layer in a first partial area and with the colored thin-film element in a second partial area, with the two partial areas each forming a pattern, character or a code and in particular being arranged at least partially in register with one another .
- the WO 2011/082761 A1 describes a thin-film element with a multi-layer structure for security papers, documents of value and the like, which appears gold-colored when viewed in reflected light and which has at least two semi-transparent mirror layers and at least one dielectric spacer layer arranged between the at least two mirror layers, so that when measuring the transmission of unpolarized light in the blue Wavelength range from 420 to 490 nm shows a resonance with a full width at half maximum of 70 to 150 nm.
- a data carrier for example a bank note, is described therein with such a thin-film element, in which the thin-film element is arranged in or above a transparent window area or a continuous opening of the data carrier.
- the invention is based on the object of providing a document of value with a document of value substrate having a perforation area, the document of value with regard to the verifiability is improved with regard to its authenticity and with regard to the protection against unauthorized reproduction of the document of value.
- observation in incident light is illumination of the document of value from one side and observation of the document of value from the same side.
- Observation in reflected light is therefore present, for example, when the front side of the document of value is illuminated and also viewed.
- viewing in transmitted light is illuminating a value document from one side and viewing the value document from another side, in particular the opposite side.
- An observation in transmitted light is therefore present, for example, when the back of the document of value is illuminated and the front of the document of value is viewed. The light thus shines through the document of value.
- the document of value mentioned in the present description can be, for example, a banknote, in particular a paper banknote, a polymer banknote or a foil composite banknote, a share, a bond, a document, a voucher, a check, a high-quality entrance ticket, but also an authorization card, an ID card or a passport personalization page.
- a banknote in particular a paper banknote, a polymer banknote or a foil composite banknote, a share, a bond, a document, a voucher, a check, a high-quality entrance ticket, but also an authorization card, an ID card or a passport personalization page.
- the film security element mentioned in the present description can be, for example, a patch or a label, an (endless) strip or an (endless) thread.
- the value document substrate is in particular a paper substrate or a paper-like substrate.
- the perforation area of the value-document substrate is formed by means of a recess which breaks through the value-document substrate and which forms a perforation-area motif.
- the break-through recess forming the break-through area motif is produced in the value-document substrate by the action of laser radiation on the value-document substrate, in particular by means of laser cutting. Laser cutting can be used to create smooth edges.
- very filigree breakdown area motifs can be created using laser radiation.
- the break-through area motif can furthermore be formed by a plurality of cut-outs breaking through the value-document substrate, which together produce a motif.
- a document of value substrate is provided with a window-like opening which is then closed with an at least partially transparent covering film, wherein the covering film can be provided with additional security features, for example diffraction structures, particularly in the region of the window-like opening.
- the der is based
- the idea on which the present invention is based is based on the finding that by means of the perforation area and a foil security element covering the perforation area, which has a transparent area and a non-transparent area that develops an optically variable effect and is based on a reflective embossed structure, when changing between a front-side and a rear view of the document of value, surprising, superordinate motifs can be generated.
- the value document substrate perforation area forms a first motif having a transparent window area and a metallization, which can be seen when viewing the value document in reflected light from the back, but cannot be guessed by the viewer when viewing the value document from the front in reflected light.
- the viewer sees a second motif in the form of the transparent window area and a third motif adjoining it in the form of a reflective embossed structure that develops an optically variable effect.
- the first motif which can be recognized by the viewer when changing from the front view to the rear view of the value document in incident light, is surprising for the viewer because it is a superordinate motif made up of two components, the first component being the second motif, which can also be recognized when viewed from the front incident light is in the form of the transparent window area and the second component is a part or a section of the non-transparent area of the film security element covering the perforation area that is recognizable when viewed from the front with incident light and develops an optically variable effect and is based on a reflective embossed structure.
- the embossed structure that can be used according to the invention is embossed in particular in an embossing varnish.
- the expression “optically variable effect” includes not only holograms but also hologram-like diffraction structures, ie, for example, structures that do not produce a defined image but instead create a blurred, colored impression. Diffraction patterns, structures with a color shift effect, kinoforms, structures with a microlens effect, structures with isotropic or anisotropic scattering effects or with other interference effects, sub-wavelength structures, moth-eye structures, microlens structures and microstructures for moiré magnifiers or modulo mappers are also subsumed under the term "optically variable effect". , micromirror structures and microprismatic structures.
- the multilayer structure capable of interference that is recognizable when viewing the front side in incident light and a second appearance of the multilayer structure capable of interference that is recognizable when viewing the front side in transmitted light, e.g. by gaps in the reflective layer and/or the semi-transparent layer.
- a film security element with different reflected light / transmitted light appearance is from WO 2009/149831 A2 known.
- the semi-transparent layer can have a large number of gaps arranged in a grid-like manner, which in their entirety result in a character, an image or a pattern. The pattern created in this way is visible in reflected light and disappears in transmitted light.
- a different reflected light/transmitted light appearance of the multilayer structure can be achieved by combining the structure with a relief structure, in particular a diffractive relief structure, a microoptical relief structure or a sublambda structure.
- Other preferred reflective embossed structures include, for example, a liquid crystal layer that exhibits a different color when viewed in reflected light than when viewed in transmitted light.
- a different incident light/transmitted light appearance can be brought about by combining the liquid crystal layer with a relief structure, in particular a diffractive relief structure, a micro-optical relief structure or a sublambda structure.
- Further preferred reflective embossed structures contain, for example, a print layer with an effect pigment composition which shows a different color when viewed in reflected light than when viewed in transmitted light, in particular a gold/blue color change, a gold/violet color change, a green-gold /magenta color change, a violet/green color change or a silver/opaque color change.
- a print layer with an effect pigment composition which shows a different color when viewed in reflected light than when viewed in transmitted light, in particular a gold/blue color change, a gold/violet color change, a green-gold /magenta color change, a violet/green color change or a silver/opaque color change.
- Such inks are, for example, in the WO 2011/064162 A2 described.
- a different incident light/transmitted light appearance can be achieved by combining the printed layer with a relief structure, in particular a diffractive relief structure, a micro-optical relief structure or a subl
- the relief structure forming a diffractive structure is in particular a hologram structure.
- the dimensions of the structural elements of the diffractive structure are preferably in the order of Light wavelength, more preferably in a range that is greater than 100 nm and less than 1 ⁇ m, with a range greater than 300 nm and less than 1 ⁇ m being particularly preferred.
- the relief structure forming a micromirror arrangement is also referred to herein as a micro-optical relief structure.
- the production of a micro-optical relief structure is known in the prior art (see, for example, WO 2014/060089 A2 ).
