摘要：Capacitive electronic discs having thin conductive layers are prepared by coatinga core disc with a finely particulate conductive composition comprising a thermoplasticresin, conductive carbon black particles and suitable additives. The powder coating iscompressed under heat and pressure to fuse the powder to the surface of the core disc.An information pattern is embossed therein, preferably simultaneously.
