Abstract: The invention concerns a process for producing a film element having mutually registered metallic layers (11, 16) and a film element which can be produced by such a process. A first metallic layer (11) provided on a first surface of a flexible single-layer or multi-layer carrier film (10) and a masking layer (13) provided on the second surface of the carrier film (10), opposite to the first surface, are structured in accurate register relationship with each other by means of mutually synchronized structuring procedures. After structuring of the first metallic layer (11) and the masking layer (13) one or more further layers are applied to the first metallic layer (11). Applied to the one or more further layers (15) is a second metallic layer (16) to which a first photoactivatable layer (17) is applied.

Abstract: Disclosed is a plastic film and to a touch module produced therefrom. The module is constructed from two conductive layers with an insulation layer in between, as are used in capacitive touch pads and/or touch screens, for example. The problem of connecting the respective x or y sensors across two planes in a cost-effective manner employs foldable sensor planes in the plastic film suitable for mass production. The connections and conductor tracks are concentrated on one plane on a sensor side wherein the sensor planes are arranged on flexible materials. The registering of the two planes relative to each other is simplified via a secure mechanical connection of the two planes via a fold in the film.

Abstract: There is described a structure (14) that is disposed on an electrically non-conductive, electrostatically chargeable strip-type carrier film (12) and that has electrically conductive and/or semiconducting structural elements, which structure has at least one structural region (14s) protected against electrostatic voltage flashover. The at least one structural region (14s) protected against electrostatic voltage flashover is connected to a protective conductor track (19) and/or surrounded by a protective conductor track (19, 19?), which is realized such that it discharges an electrostatic charge and/or shields the protected structural region (14s).

Abstract: The invention provides a large number of possibilities for how, in the case of a multi-layer body with electrically conductive elements which are not visible to the naked eye, the electrically conductive elements can be prevented from excessively reflecting light back. Here, a suitable surface roughness for the electrically conductive elements can be selected, or at least one additional layer (54) can be provided on the electrically conductive elements (51l).

Abstract: The invention concerns a film, in particular a stamping film, laminating film or sticker film, which has at least one anisotropic polymer layer of an at least partially oriented liquid crystal material. The anisotropic polymer layer has one or more first regions which form a first security feature and in which the anisotropic polymer layer has properties which linearly polarise or which rotate the direction of rotation, and one or more second regions which form a second security element and in which the anisotropic polymer layer has circularly polarising properties. The first security feature is visualised when viewed through a first polariser and the second security feature is visualised when viewed through a second polariser responsive to a different polarisation state from that of the first polariser.

Abstract: The invention concerns a process for the production of a personalised, optically variable element having polarising properties, and a film system for carrying out the process. To produce the optically variable element a film body which comprises two or more layers and which has an LCP layer comprising a liquid crystal material is applied to a substrate body which has an orientation layer for the orientation of liquid crystals. The orientation layer of the substrate body is personalised prior to application of the film body to the substrate body. The film body is then applied to the personalised orientation layer of the substrate body in such a way that the LCP layer of the film body lies on the personalised orientation layer of the substrate body for then orientation of liquid crystals of the LCP layer of the film body.
