ABSTRACT:
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:
