摘要： The present invention is an electrically conductive coating composition comprising, as indispensable components, a quaternary ammonium polymer and a polyvalent metal salt. As the quaternary ammonium polymer there can be preferably used a polymer containing at least 30 weight % of quaternary ammonium monomer unit such as 2-methacryloyloxyethyltrimethylammonium chloride or 2-methacryloyloxyethyltrimethylammonium methylsulfate. As the polyvalent metal salt there can be used sulfate, hydrochloride, nitrate or the like of at least one polyvalent metal selected from the group consisting of iron, copper, cobalt, calcium, zinc, lead, nickel, manganese, aluminum, magnesium, titanium, cadmium, chromium, barium and tin. The electrically conductive coating composition of the present invention is extremely excellent in water retention characteristics and therefore has sufficient electric conductivity under circumstances of low humidity even at low coating weight. Thus, according to the present electrically conductive coating composition there can be obtained an electrostatic recording paper which can be used under circumstances of low humidity without thickening the conductive layer.
