MEHRSCHICHTKÖRPER UND VERFAHREN ZUM HERSTELLEN EINES MEHRSCHICHTKÖRPERS
摘要:
The invention relates to a multilayer body comprising a support and a layer which is arranged on the support and comprises an electrically conductive material in a specific arrangement. The multilayer body comprises an information region and a background region (18) which are galvanically separated from each other. Each information region is equipped with a first zone (10) which comprises an electrically conductive material, and the electrically conductive material of the first zones is connected in a conductive manner over the totality of the first zones. Each background region is equipped with a plurality of second zones which comprise an electrically conductive material and which are galvanically separated from one another. Each of the first zones (10) preferably takes up a surface area which is larger than each of the second zones by a factor of at least five. The electrically conductive material is preferably provided with an average surface coverage which varies by less than 25% over all the information regions and the background regions (18). In this manner, a homogenous appearance of the multilayer body is provided, and information provided in the information region by means of the shape, size, and/or alignment of the first zone is not visible without an aid and therefore cannot be copied.
