OPTICAL INFORMATION MEDIUM AND PRODUCTION METHOD THEREFOR

摘要

The present invention provides an optical information medium that is less susceptible to warp in the disk surface while offering significantly high scratch resistance and abrasion resistance, and a method for producing the optical information medium. An optical information medium (1) comprising a supporting substrate (2) and a film element, the film element disposed on the supporting substrate (2) and composed of one or more layers including at least a recording layer (5) or a reflective layer (3), wherein at least one of the supporting substrate-side surface and the film element-side surface is formed of a hard coat layer (9) of a cured product of a composition comprising (A) inorganic fine particles with an average particle size of 100nm or less, (B) a reactive silicone, and (C) an active energy ray-curable compound. <IMAGE>
