Abstract: Electroconductive paper structure with cellulosic fibrous materials and electroconductive fibers, wherein the electroconductive paper structure has embedded therein a continuous, electroconductive thread for contacting the electroconductive paper structure from one end to the opposite end of the paper structure.

Abstract: A micro-optical inspection arrangement comprises micro-focusing elements which are composite bodies consisting of a main part and an additional part and which have a reference focal length. The main parts are provided as micro-focusing element preforms, and the additional parts are formed from one or more functional coatings. The invention also relates to a method for producing such a micro-optical inspection arrangement and to a micro-optical displaying arrangement comprising the micro-optical inspection arrangement according to the invention and a microstructure arrangement, in particular a moiré magnification arrangement and a modulo magnification arrangement. The invention also relates to security elements and data carriers that have the micro-optical inspection arrangement according to the invention.

Abstract: A method for manufacturing a security paper includes an endless microlens thread having a top and an opposing bottom with the top provided at least in fractional regions with microlenses. A paper web having a predetermined ridge pattern is produced and defines ridge regions in which the microlens is embedded in the interior of the paper, and that exhibits, lying between the ridge regions, window regions in which the microlens thread emerges at the surface of the paper web. The microlens thread is introduced into the paper web and, at the same time, is joined on its bottom and, in the ridge regions, also on its top with the paper web. The paper web with the microlens thread forms the security paper.
