Abstract
Sandwich-type capacitive electronic discs having thin conductive layers are prepared by adding a thermally processed conductive molding composition comprising a thermoplastic resin, conductive carbon black particles and suitable additives to a suitable solvent to form a dispersion of the conductive carbon black in a solution of the remaining ingredients. The dispersion is filtered to remove impurities larger than a predetermined particle size and coated onto a core disc. The coating is dried to form a conductive layer which is embossed with the desired information.
