Abstract
A substrate material, preferably polycarbonate, suitable for producing transparent injection-molded coated disks is disclosed. The material is characterized in that a substrate molded therefrom has an electrical field (measured within 5 minutes of its molding and at a distance of 100 mm from the surface) of −30 to 0 kV/m.
