  • Patent number: 5962148
    Abstract: The present invention is an electrically conductive paint composition comprising 100 parts by weight of a (meth)acrylate compound having at least two (meth)acryloyl groups in one molecule, 0.1 to 30 parts by weight of a particulate anilinic electrically conductive polymer, 1 to 100 parts by weight of an alkyl (meth)acrylate resin, 0.01 to 10 parts by weight of a photopolymerization initiator and 0 to 2000 parts by weight of an organic solvent. The compositions can be easily cured by active rays of light. The resulting electrically conductive film is excellent in surface hardness, transparency, resistance to chemicals, and abrasion resistance, and the paint compositions being excellent in storability. Thus, the electrically conductive paint compositions are suitable for antistatic materials in semiconductor-preparating processes.
