ABSTRACT:
A high density information record of the electrostatic capacitance type comprising a record substrate on which signal information is recorded as geometric variations. The record substrate is made of a conductive resin composition comprising a vinyl chloride resin and a conductive powder. The vinyl chloride resin is obtained by suspension polymerization of starting vinyl chloride monomer in an aqueous solution of a water-soluble polymer suspension stabilizer from which insoluble organic matters with sizes over 10 .mu.m have been removed.
