Abstract

Abstract An electrically conductive composition of the invention comprises 100 parts by weight of a (meth)acrylate compound possessing at least two (meth)acryloyl groups, 1 to 100 parts by weight of an anilinic electrically conductive polymer, and 0.1 to 20 parts by weight of a photopolymerization initiator sensitized by active rays. This electrically conductive composition may also comprise an unsaturated compound possessing any one group selected from the group consisting of a phosphoric acid group, a sulfonic acid group and a carboxyl group. Between the surface of a form to be coated and the coating layer made of the electrically conductive composition formed thereon, an inorganic electrically conductive layer composed of the tin oxide powder containing antimony with mean particle size of 0.01 to 0.4 mu m, or the barium sulfate powder coated with tin oxide containing antimony with mean particle size of 0.01 to 2 mu m, and a synthetic resin may be provided.
