Magnetic recording medium and magnetic composite particles for magnetic recording medium

摘要

A magnetic recording medium comprising: a non-magnetic base film; and a magnetic recording layer comprising a binder resin and magnetic composite particles which have an average particle diameter of from 0.02 to 0.70 mu m and which comprise: (a) magnetic core particles, (b) a coating provided on the surface of said magnetic core particles, comprising at least one organosilicon compound selected from: (1) organosilane compounds obtainable from alkoxysilane compounds, and (2) polysiloxanes or modified polysiloxanes, and (c) a phthalocyanine-based pigment coat which is provided on said coating (b) in an amount of 1 to 100 parts by weight per 100 parts by weight of said magnetic core particles (a).
