Definitions

  • the present invention relates to a method for producing a security element with two security features.
  • the invention is based on a method which comprises the following method steps: (a) provision of a photosensitive film which has at least one carrier layer and a photosensitive functional layer applied flatly thereon and optionally a protective layer on the side of the photosensitive functional layer opposite the carrier layer; (b) exposing the photosensitive film to a pattern; and (b ') optionally fixing the exposed photosensitive film to form a security element having a security feature.
  • the present invention also relates to the use of the method for producing a value or security document.
  • security features may be formed by special colors, for example luminescent or optically variable colors, optical elements, such as holograms, tilt images, kinegraphic objects, lens or prism arrays, also guilloches, mottling fibers, security threads and others.
  • optical security features in the form of security elements can be manufactured separately and then glued as patches, layers, security threads, security strips or the like on an external surface on the security document or on an internal surface in the security document the latter case will be integrated into the document.
  • Such security elements may be optically variable elements, so that visually perceptible phenomena produced therewith may either be recognizable or not recognizable and / or take different forms, depending on the angle at which the security or security document is viewed.
  • value or security documents can be provided with a security feature produced on holographic, in particular volume holographic, paths.
  • DE 10 2009 007 552 A1 discloses a method for producing multilayer security products which consist of at least one card and at least one polymer film applied to at least one side of the card, wherein the polymer film is provided as a roll product and provided with at least one security feature is.
  • a roller path of the polymer film and at least one strip with an n-fold number of uses are fed to a laminating station and laminated.
  • a control line which is assigned to the at least one security feature to be applied to the respective benefit or a control line and / or the reference mark associated with the use or the strip are interrogated on the polymer film.
  • a feed speed and / or a feed direction are adapted by the roller track of the polymer film and the strip for exact alignment with one another.
  • the roller track of the polymer film can be individualized and contain, for example, holograms.
  • the optical diffraction elements are therefore initially provided in the form of rolls, a roll containing a plurality of optical diffraction elements. After completion of all optical diffraction elements of a roll, they are connected to the blanks of the identity documents assigned to them. Since this plurality of optical diffraction elements, which are located on such a roll and define a production lot, can only be processed further when all optical diffraction elements of this roll are completed, the result is a significant delay in the process, at least for those optical diffraction elements on the roll, which were first produced. Therefore, there is a problem that the time required for the production of a value or security document is also significantly determined by the period of time required to produce all the security elements on the web material of a roll of security elements.
  • DE 10 2015 210 522 A1 proposes a method for producing a multi-layer value or security document which is formed at least by a polymeric base layer and a security element laminated thereon.
  • This process comprises the following process steps: (a) use of polymeric base material in the form of polymeric base layer-benefit polymeric base material single or multiple use; (b) providing web material in roll format to provide a plurality of security features; (c) generating the security elements on and / or in the web material; (d) merging and stacking each of a polymeric base material single or multiple benefit and security elements benefit each other so that each of a polymeric base layer benefit and a security element benefit is accurately aligned; and (e) laminating the respective polymeric base ply benefits and security patches together, wherein security ma- terials single or multiple scores having one or more security benefits are singulated from the roll stocked web material, and; then the safety material single or multiple uses in the process steps (d) and (e) are processed.
  • DE 10 2015 226 604 A1 specifies a method for integrating a hologram in a security document body, which comprises a lamination body.
  • the method comprises the steps of: providing a hologram film having a carrier substrate layer and a photo layer; Providing further substrate layers and performing lamination to form the lamination body.
  • the hologram film is gathered together with the further substrate layers to form a substrate layer stack and combined with the further substrate layers in a lamination process to form the lamination body.
  • DE 10 2015 226 604 A1 states for this that the further substrate layers used to produce the document can have printing. It is likewise mentioned in DE 10 2015 210 522 A1 that the card formats used for the production of the documents can already be individualized by means of a facial image which can be produced with the aid of a printing method. Another disadvantage of these methods is that the methods are very long, so that the expense of producing the documents is considerable.
  • hologram must be applied to the card raw body in oversize and individual benefits are then produced via a punch, whereupon it is only then possible to dispose of erroneous benefits from the production process.
  • value or security document includes, for example, a passport, identity card, driver's license, an access control card or another ID card, a vehicle registration document, vehicle registration document, visa, check, means of payment , in particular a banknote, a check, bank, credit or cash card, customer card, health card, chip card, a company card, proof of eligibility, membership card, gift or purchase voucher, bill of lading or other proof of entitlement, tax stamps, postage stamps , Ticket, token or other document to understand.

  • the value or security document may be in ID 1, ID 2, ID 3, or any other normalized or non-normalized format, such as in a booklet form, such as a passport-like item, or, for example, in card form.
  • a value or security document is generally a laminate of a plurality of document layers, which are connected in register under the action of heat and under increased pressure.
  • Value or security documents should comply with the standardized requirements, for example in accordance with ISO 10373, ISO / IEC 7810, ISO 14443 in the version version valid at the filing date of this application.

  • a photograph or a motif of an original produced in another way may also be produced in the photosensitive functional layer.
