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.

Magnetic recording medium comprising a syndiotactic styrene-based

A curable resin composition is a blend of a curable phosphazene compound with a pentaerythritol acrylate compound and/or a bis(4-acryloxydialkoxyphenyl)alkane compound in a ratio of the former to the latter ranging from 90 to 10 to 5 to 95. The curable resin composition is provided with excellent properties such as a surface hardness, transparency and so on, and it can be cured at an improved curing rate.

Curable resin compositions

A laminated film contains a base film having a conductive layer on one side thereof and a layer obtained by curing a curable phosphazene composition coated on the other side thereof. The laminated film is suitable for use in a touch panel having a switching function when pressing an operating section of the touch panel, the operating section being made from the cured layer of the phosphazene composition. The laminated film has a remarkably balanced combination of the properties, i.e., adhesion, surface hardness and appearance on the coat surface (shrinkage upon curing).

Laminated films for use in a touch panel

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 of 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.

Styrene-based resin composite material

Protective film for photo masks and lith films

Provided herein is a coated resin molded-article which comprises a polyester resin substrate and a cured coating formed thereon which contains a curable phosphazene compound. The molded article will find use as film, sheet, and container which have improved abrasion resistance, weather resistance, heat resistance, heat shock resistance, hot water resistance, moisture resistance, alkali resistance, impact resistance, cloud resistance, transparency, oil resistance, surface gloss, and air barrier properties, while keeping the good properties of the resin.
