ABSTRACT:
A high density information record of the electrostatic capacitance type which comprises a record substrate on which signal information is recorded as geometric variations. The substrate is made of a conductive resin composition comprising a thermoplastic resin, a conductive material, and a defined amount of a specific type of dimethylpolysiloxane lubricant having a degree of inhomogeneity of 1.0 to 1.3 and a degree of polymerization of 12 to 60.
