HARD COATING MATERIAL COMPOSITION AND OPTICAL INFORMATION MEDIUM USING SAME

WIPO Patent Application WO/2005/033231

A1

Disclosed is a hard coating material composition which is useful for forming a hard coating layer on the surfaces of various articles which hard coating layer is excellent not only in antifouling properties and lubricating properties but also in abrasion resistance and wear resistance. Also disclosed is an optical information medium using such a hard coating material composition. The hard coating material composition contains a fluorine-containing polyether compound (A) having an active energy ray-reactive group, and a curing compound (B) having 2 or more active energy ray-polymerizable groups in a molecule. The optical information medium comprises a film body composed of one or more layers including at least a recording layer (4) or a reflective layer on a supporting base (20). At least one of the supporting base (20) side surface and the film body side surface is composed of a hard coating layer (8) which contains a cured product of the hard coating material composition.
