The present invention relates to a security element () for securing valuable articles, having a first layer (), composed of cholesteric liquid crystal material, that is present at least in some areas, a second layer (), composed of liquid crystal material, that is present at least in some areas, and a further layer (), having a machine-readable feature, that is present at least in some areas and that is covered at least in some areas by the first and second layer composed of liquid crystal material.

Security element and method for producing the same

The invention relates to sheet material having an electrical circuit and to apparatuses and methods for processing said sheet material. The present invention describes sheet material having an electrical circuit as well as apparatuses and methods for processing same, which reduce the effort required for processing the sheet material and/or facilitate processing and/or improve it and/or make it more reliable. For this purpose, the sheet material has at least one electrical circuit, with energy and/or data being transmitted from the apparatus to the electrical circuit and/or from the electrical circuit to the apparatus and at least part of the transmitted data being used for processing.

Devices and method for the production of sheet material

The present invention relates to a foil material for transfer to a target substrate, and methods for manufacturing such a foil material. In a method according to the present invention, a plastic substrate foil () is provided that is suitable for aligning liquid crystal material. To the substrate foil () is discontiguously applied a layer () comprising a liquid crystal material that is aligned.
