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.

Electrically conductive paper structure, method for manufacturing same and use

A method for producing pigments comprises the steps of creating a first layer on a substrate, structuring the first layer and detaching the pigments from the substrate. In the present case, the first layer is a crack-forming layer, so that the first layer is structured by the arising of cracks. Prior to detaching the pigments, a pigment layer is applied onto the first layer structured by the cracks.

Method for producing pigment fragments with a predefined internal and/or external contour using a crack-forming layer, and pigment fragments

A method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.
