High density information record medium.

摘要

@ An information signal record medium of an electrostatic capacitance type on which signal information is recorded as geometric variations, such as a video or audio disc, consists essentially of a conductive resin composition which comprises a vinyl chloride resin and 5 to 30 parts by weight of conductive particles per 100 parts by weight of the vinyl chloride resin. The vinyl chloride resin is obtained by polymerizing vinyl chloride monomer in the presence of 0.2 to 1 parts by weight of a lubricant per 100 parts by weight of the vinyl chloride resin.
