ABSTRACT:
A conductive polyester-based alloy sheet having three layers laminated together by co-extrusion, which comprises one substrate layer and two surface layers, wherein the surface layers are conductive and comprise polyester, acrylonitrile-butadiene-styrene (abbreviated as ABS) and/or polystyrene (abbreviated as PS), a compatibilizer, and a toughening agent, wherein the surface layers have a surface conductivity of not more than 10.sup.8 ohms. The melt flow index of the material for the conductive layers during the extrusion step is not less than 5.0 g/min (loading, 10 Kg; temperature, 250.degree. C.). The substrate layer is made from acrylonitrile-butadiene-styrene and/or polystyrene.
