Abstract
Abstract A shaped article formed from a polyarylether is coated on at least part of one surface thereof with a polyester resin containing free sulphonate groups. The polyarylether can be a polyarylether-sulphone or a polyaryletherketone such as polyaryletheretherketone. The shaped article can be a sheet or a film. The coated article may have further coatings applied, for example the coated article may be metallized.
