It is an object of the present invention to provide an optical recording medium wherein hardness of the surface on the incident-light side is high and warping of the optical recording medium is suppressed. n The optical recording medium according to the present invention comprises a substrate 11 , a recording layer 14 provided upon the substrate 11 , a light transmission layer 16 made of ultraviolet curable resin provided upon the functional layer 16 , and a hard-coat layer 17 provided upon the light transmission layer 16 , wherein the thickness of the light transmission layer 16 is 50 μm or greater and its pencil hardness is HB or less. Thereby, warping of the optical recording medium arising due to cure shrinkage of the ultraviolet curable resin making up the light transmission layer 16 can be effectively suppressed. Moreover, the hard-coat layer 17 is provided upon this light transmission layer 16 , so the occurrence of scratches on the surface of the optical recording medium can be effectively prevented. |
