<P>PROBLEM TO BE SOLVED: To provide a curable composition used for a light transmission layer of an optical recording medium having good resistance to high temperature and indentation, good low warping properties and good resistance to high temperature and high humidity; and an optical recording medium. <P>SOLUTION: The curable composition comprises a radical polymerizable compound and a photoinitiator. By forming a light transmission layer composed of a cured material layer of an active energy ray curable resin composition comprising, as a radical polymerizable compound, 20 to 100 mass% of a polyfunctional (meth)acrylate compound modified with 7 to 22 propylene oxides in 1 molecule relative to the total amount of a radical polymerizable compound, an optical recording medium can be obtained which is excellent in resistance to high temperature and indentation, low warping properties and resistance to high temperature and high humidity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
