Abstract: An optical recording medium 10 comprises a disc body 11, a white ink layer 12 provided on the label side 11b of the disc body 11, and an ink receiving layer 13 provided on the surface 12a of the white ink layer 12. The mean roughness (Ra) of the surface 12a of the white ink layer 12 is set not greater than 0.2 μm. A step radially extended is left on the surface 13a of the ink receiving layer 13 and set not greater than 1.0 μm. As the mean roughness (Ra) of the surface 12a of the white ink layer 12 is not greater than 0.2 μm or as the step on the ink receiving layer 13 is not greater than 1.0 μm, high printing quality can be secured when printing is done with an ink-jet printer.

Abstract: 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.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.

Abstract: The invention provides an optical recording medium having excellent weatherability and a process for producing the same. The optical recording medium is provided with an organic dye layer, a reflecting layer and a protective layer in this order on a light-transmittable substrate. The organic dye layer contains an organic solvent in an amount of 2% to 15% by weight based on the organic dye. A solution, prepared by dissolving an organic dye in an organic solvent, is applied onto the light-transmittable substrate by a spin coating method to form an organic dye layer. A reflecting layer is formed on the organic dye layer without performing a drying treatment of the organic solvent in the organic dye layer, followed by forming the protective layer on the reflecting layer. The result is an optical recording medium containing an organic solvent in an organic dye layer in an amount of 2% to 15% by weight based on an organic dye.
