STYRENE-BASED RESIN COMPOSITE MATERIAL AND USE THEREOF

摘要

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 an ink ribbon in which an ink layer is provided on one side of a film of the above polymer or a composition thereof and a heat resistant lubricating layer composed mainly of the curable phosphazene compound provided on the side opposite thereto, 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, a 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.
