Magnetic recording medium

摘要

A magnetic recording medium comprising: (a) a non-magnetic base film; and (b) a magnetic recording layer comprising a binder resin, magnetic particles and, as a filler, black composite hematite particles which have an average diameter of from 0.08 to 1.0 mu m and which comprise: hematite particles as core particles; a coating layer provided on the hematite particles, comprising at least one organosilicon compound selected from: (1) an organosilane compound obtainable from an alkoxysilane compound; (2) a polysiloxane or modified polysiloxane; and (3) a fluoroalkyl organosilane compound obtainable from fluoroalkylsilane compound; and a carbon black coat provided on said coating layer, in an amount from 1 to 30 parts by weight based on 100 parts by weight of said hematite particles.
