Disclosed are a styrene-based resin composite material in which a layer composed mainly of a curable phosphazene compound is formed on the surface of a molding material of a styrene-based polymer having a mainly syndiotactic configuration or a composition thereof, and also a magnetic recording medium characterized in that a magnetic layer containing the curable phosphazene compound as a binder on a support composed of the above polymer or a composition thereof, an over coated layer of a magnetic recording medium which contains the curable phosphazene compound and a lubricating layer of a magnetic recording medium which contains the curable phosphazene compound.
A magnetic recording medium which comprises a support of a styrene-based polymer having a syndiotactic configuration or a composition thereof, a magnetic layer containing a curable phosphazene compound as a binder formed on the support and a lubricating layer containing a curable phosphazene compound formed on the support at the opposite side of the magnetic layer.
