Antistatic plastic films

Abstract

An antistatic plastic film is described. This comprised of a plastic film and at least one coating layer provided on the surface of the plastic film. The coating layer is prepared by dispersing electrically conductive fine particles in a compound containing an unsaturated bond capable of undergoing polymerization on irradiation with radiation or a binder containing the polymerizable compound. The electrically conductive fine particle comprising crystalline metal oxide of Zn, Ti, Sn, In, Si, Mo or W and/or composite oxide thereof. The resulting dispersion is coated on the plastic film, polymerized and cured by irradiation of the layer with radiation. The film can be easily, quickly and economically produced and is substantially transparent while providing improved antistatic properties good mechanical strength.
