Abstract: The invention concerns a process for producing a high-resolution surface pattern on a substrate and a multi-layer body produced by means of that process and an apparatus for carrying out the process. A printing substance is applied in pattern form to the substrate by means of a printing process. For fine structuring of the surface pattern, prior to application of the printing substance, a microscopic surface structure with a plurality of grooves is replicated into the surface of the substrate. The fine structuring of the surface pattern is determined by the respective locally applied application amount of printing substance and the respective local relief parameters of the microscopic surface structure in particular orientation direction and profile shape.

Abstract: The invention concerns a film having at least one electrical component and a process for the production of such a film. An adhesive layer comprising a radiation-cross-linkable adhesive is applied to a base film. The adhesive layer is applied to the base film in a form of being structured in pattern form and/or is irradiated in pattern form in such a way that the adhesive layer hardens with structuring in pattern form. A transfer film which comprises a carrier film and an electrical functional layer is applied to the adhesive layer. The carrier film is pulled off the film body comprising the base film, the adhesive layer and the electrical functional layer, wherein in a first region structured in pattern form the electrical functional layer remains on the base film and in a second region structured in pattern form the electrical functional layer remains on the carrier film and is pulled off the base film with the carrier film.

At least one component produced using organic semiconductor technology, in particular one or more organic field effect transistors, is integrated into a film (1).

Abstract: The invention concerns a process and an apparatus for the production of a partially metallised film element and a partially metallised film element produced by means of the process. A digital data set (332) which defines the graphical shape of the partial metallisation is produced. A tool path and control data for actuation of a tool (38) are calculated from the digital data set (332). The tool (38) and a single-layer or multi-layer film body (30) are moved relative to each other in accordance with the tool path. The tool (38), controlled by the control data, produces partial digital demetallisation of a metal layer (31), in particular by applying an etching agent or an etching resist or by erosion of the metal layer (31).

The optically variable element has a thin film layer (54, 55, 58) for producing color change by means of interference and a further layer (51, 52, 53, 59). The thin film is in the form of a partial thin film element which covers the surface region of the further layer only in region-wise and pattern-shaped manner.

Abstract: The invention relates to an optically variable element, in particular an optically variable safeguard element for safeguarding banknotes, credit cards and the like. The invention also relates to a security product and a foil, in particular an embossing foil or a laminating foil, having such an optically variable element. The optically variable element has a thin film for producing color shifts by means of an interference and/or a reflective layer. The optically variable element further has a transparent window. The interference film and/or the reflective layer include a partial element, namely a partial thin film element or a partial reflective element, respectively. The partial element or elements surround the surface region of the transparent window.

Abstract: The invention concerns an optically variable element and a security product having such an optically variable element, a foil, in particular an embossing foil or a laminating foil having such an optically variable element, and a process for producing such an optically variable element. The optically variable element has a thin film layer succession with at least one spacer layer for producing color shifts by means of interference. In a first region of the thin film layer succession the spacer layer is of a different layer thickness from in a second region of the thin film layer succession. In that case the layer thicknesses of the spacer layer in the first and second regions are so selected that in the first region of the thin film layer succession a first color shift is produced by means of interference and in the second region of the thin film layer succession a second color shift which is different from the first color shift is produced.

Abstract: Described is a process for the region-wise transfer of a decorative layer of a transfer foil, which includes an activatable adhesive layer from a carrier film onto a substrate, wherein the adhesive layer of the transfer foil is partially activated before the actual stamping operation, more specifically in such a way that the adhesive layer experiences activation only in the surface regions in which the decorative layer is to be transferred onto the substrate. A transfer foil which is particularly suitable for that process has an absorption layer in the surface regions of the decorative layer, which are to be transferred onto the substrate, which absorption layer absorbs the radiation energy causing activation of the adhesive layer and activates the adhesive layer under the action of the absorbed radiation energy.

In addition at least two kinds of scanning elements may respectively involve different, optically effective structures. A thermotransfer foil for the production of such a scanning image is also described.

Abstract: An embossing foil such as a hot embossing foil is of a laminate structure comprising in succession a backing foil, a separating layer, a transparent cover lacquer, a decorative layer means and a foundation layer of an at least translucent material. The decorative layer means successively comprises a first decorative layer adjacent to the cover lacquer layer, an opaque intermediate layer and a second decorative layer adjacent to the foundation layer. The opaque intermediate layer can be covered at least on one side with a single-colored layer over a large area thereof.
