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.

- 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.

- 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.

Another disadvantage of these methods is that the methods are very long, so that the expense of producing the documents is considerable.

- a further outer polymer layer may be formed as scratch-resistant layer and for this purpose of polyethylene terephthalate or polycarbonate or other suitable polymer, such as an acrylate polymer formed.
- This further outer polymer layer is more preferably the one which is arranged on the (main) side (back), which is opposite to the (main) side of the document (front side) on which the security element is arranged.
- An inner polymer layer in the security or security document may be provided with an individualizing or non-individualizing security printing, for example with a guilloche print and / or with logos and / or with a card number and / or with general information about the body issuing the card ,
- the carrier layer of the security element in the layer stack rests against the at least one polymer layer to which the security element is connected.
- the protective layer of the security element is located on one of the outsides of the security or value document.
- the carrier layer is printed to form the second security feature, the imprint is placed inside the document. This protects the print against tampering.
- the carrier layer is arranged on the outside of the document, ie that the protective layer bears against the at least one polymer layer, in particular if the protective layer is formed from polycarbonate. If in this case the carrier layer is printed to form the second security feature, this printing is exposed on the surface of the document.
- the protective layer in this arrangement is arranged inside the document, it can additionally be printed to form the second security feature in order to arrange the printing on the inside. Since the protective layer is usually very thin, a diffraction-optical element in the functional layer can be impaired at least at the locations where printed surface areas are located, ie the printing influences the diffraction-optical element in this case, so that the printing is the diffractive optical element Element overlaid. Because solvent of the ink, for example, the formed diffraction grating can be widened, so that the diffraction conditions change locally. This reduces the sharpness of the reconstructed image. In addition, this change can influence the colors of the diffraction image.

- these document components can be stacked on one another at a document stack location in a device suitable for this purpose and then fixed together.
- the individual constituents are preferably stacked on registration marks contained therein, so that they come to lie one above the other in register.
- the components can either be fixed to one another in a detachable or inseparable manner: either the components can be connected to one another by spot welding, or mechanical means, such as clamps, are used to firmly join the components together in a layer stack before finally joining them become.
- the security element and the at least one polymer layer or the raw document body are joined together (joined) by lamination.
- a conventional hot / cold lamination method is used, in which the fixed stack of the security element and the at least one polymer layer (or an already past raw document body) is first pressed under elevated pressure and elevated temperature for a first predetermined period of time and then under Increasing the pressure is cooled and maintained in this state for a second predetermined period of time under any further increased pressure.
- the pressure in the hot pressing phase is preferably at least 20 N / cm 2 , preferably in the range from 20 N / cm 2 to 100 N / cm 2 .
- the temperature during the hot pressing phase is preferably in the range of 150 ° C to 200 ° C, and more preferably in the range of 160 ° C to 195 ° C.
- Protective film are coated on which the security element is located. This film serves the further protection of the security element. It is possible to use a protective lacquer, for example based on an acrylate lacquer.
- a value or security document produced according to the invention can have, in addition to the described security features, further security features which are either individualizing or non-individualizing.
- Other security features include, for example, mottled fibers, guilloches, watermarks, embossing prints, security threads, microwriting, tilt images, transmitted light register and the like.

- the volume hologram may include a (not individualizing) logo (not shown) next to the face image.
- a photosensitive film 200 is provided. This is formed by a support layer 210, for example 50 ⁇ m thick, a photosensitive functional layer 220 lying flat against it, which for example can have a thickness of 15 ⁇ m, and a protective layer 230, which may have a thickness of 10 ⁇ m to 20 ⁇ m, for example.
