PROBLEM TO BE SOLVED: To execute sufficient printing always stably with a thermal transfer printer and to obtain sufficient resolution by incorporating a compd. which has a solubility parameter in a specific range, does not contribute to UV curing and does not react with the other components in an ink compsn. into a UV curing compsn. to be used for a printing layer. SOLUTION: A recording layer, a metallic reflection layer, a protective layer and the printing layer are laminated on a transparent substrate. The printing layer cures the ink compsn. consisting essentially of a UV curing resin. The compd. which has a solubility parameter within a range of 7 to 10, does not contribute to UV curing and does not react with the other components in the ink compsn. is incorporated into the ink compsn. of such optical recording medium. The compd. is preferably at least one kind among paraffin, acrylate oligomer and oil and fat. |
