Abstract
A conductive polyester sheet having three layers, comprising one substrate layer and two surface layers, laminated together by co-extrusion is provided. All the three layers are made from polyester and/or copolyester, and the surface layers further contain carbon black and thus are useful as conductive layers. The sheet has a surface conductivity of not more than 10.sup.8 ohms and the flow index of the material for the conductive layers during the extrusion step is not lower than 60 g/min (loading, 2160 g; temperature, 275.degree. C.).
