摘要：The present invention provides an optical information medium that is lesssusceptible to warp in the disk surface while offering significantly high scratch resistanceand abrasion resistance, and a method for producing the optical information medium. Anoptical information medium () comprising a supporting substrate () and a film element,the film element disposed on the supporting substrate () and composed of one or morelayers including at least a recording layer () or a reflective layer (), wherein at least one ofthe supporting substrate-side surface and the film element-side surface is formed of ahard coat layer () of a cured product of a composition comprising (A) inorganic fineparticles with an average particle size of 100 nm or less, (B) a reactive silicone, and (C) anactive energy ray-curable compound.
