<P>PROBLEM TO BE SOLVED: To provide a hard coating film whose curling property is remarkably reduced and which obtains high pencil hardness, and is excellent in scratch resistance, adhesiveness between the hard layer and a transparent substrate, and abrasion resistance. <P>SOLUTION: The hard coating film which has the hard coating layer on the transparent substrate is characterized in that the hard coating layer is obtained by curing an ionizing radiation-curable composition comprising a vinyl polymer (A) having three or more radical polymerization double bonds and a weight-average molecular weight of 5,000-100,000, a compound (B) having at least three (meth)acryloyl groups in the molecule, colloidal silica (C), and hydrolysate of (meth)acrylate (D) having a silicon atom of a general formula (1). <P>COPYRIGHT: (C)2008,JPO&INPIT |
