A composite film comprising a polymeric substrate and a transparent conductive layer, said conductive layer being derived from a coating composition containing: (i) electrically conductive particles selected from the group consisting of metal oxides and doped metal oxides; (ii) poly(vinyl alcohol); and (iii) an aqueous solvent, wherein the sheet resistance of the conductive layer is no more than 1,000 ohms per square, and wherein the ratio by weight of said electrically conductive particles to said poly( vinyl alcohol) is defined as W M : W P , and W M :W P is in the range of from about 2.0:1 to about 4.0:1. |
