摘要： An information signal record medium of an electrostatic capacitance type in which a signal information is recorded as geometric variations is described. The medium is made of a conductive resin composition which comprises a vinyl chloride resin and 5 to 30 parts by weight of conductive particles based on 100 parts by weight of the vinyl chloride resin. The vinyl chloride resin is obtained by polymerizing at least one monomer for the vinyl chloride resin in which from 0.2 to 1 parts by weight of a lubricant per 100 parts by weight of the vinyl chloride resin is dissolved.
