摘要： Proposed is a novel electroconductive composite plastic resin sheet consisting of an insulating base sheet of a plastic resin and an electroconductive coating layer formed on at least one of the surfaces of the base sheet, which is suitable as a material of a carrier tape used in transportation, storage and mounting works of chip-formed electronic devices such as ICs. The electroconductive composite plastic resin sheet of the invention characteristically consists of: (A) a base sheet having a thickness in the range from 100 to 1000 .mu.m formed from an electrically insulating polystyrene-based plastic resin; and (B) a coating layer having a thickness in the range from 0.1 to 30 .mu.m formed on at least one surface of the base sheet from an electroconductive coating composition comprising: (a) 100 parts by weight of an acrylic urethane-based resin as the vehicle of the coating composition to form the matrix phase of the coating layer; and (b) from 15 to 35 parts by weight of electroconductive particles having an average particle diameter in the range from 0.05 to 1.0 .mu.m uniformly dispersed in the vehicle resin, the surface of the coating layer having a surface resistivity in the range from 10.sup.4 to 10.sup.8 ohm at 23.degree.
