1. A method for treating a paper to provide at least a part of the paper with anisotropic electric conductivity, comprising
applying to the paper a dispersion comprising a non-aqueous, liquid dispersing agent and electrically conductive particles,
applying an electric field over at least part of the paper, so that a number of the conductive particles are aligned with
the field, thus creating electrically conductive pathways;
wholly or partially eliminating the dispersing agent and allowing the paper to dry thereby stabilizing and preserving the
electrically conductive pathways in the paper.
