Abstract
A multilayer body with a carrier and a layer arranged thereon which comprises electrically conductive material in such an arrangement comprises an information area and a background area () which are galvanically separated from each other. In each information area a first zone () with electrically conductive material is provided, over the entirety of which electrically conductive material is conductively connected to it. In each background area a plurality of second zones with electrically conductive material is provided, which are galvanically separated from each other. Each first zone () preferably occupies a surface area that is at least five times larger than each of the second zones. The electrically conductive material is preferably provided with an average surface coverage which varies over all information areas and background areas () by less than 25%. A homogeneous appearance of the multilayer body is thereby ensured, and an item of information provided in the information area, provided by the shape, size and/or alignment of the first zone, is not visible without aids, and therefore cannot be copied.
