PURPOSE:To obtain an optical recording medium enhanced in the reflectivity of a non-recorded part and suitable for a write-once optical disk. CONSTITUTION:A recording layer containing an org. dye, an optical interference layer having a low extinction coefficient and a reflecting layer are successively laminated on a substrate. At this time, a naphthalocyanine compd. is used as the org. dye. The obtained recording medium is enhanced in the reflectivity of a non-recorded part and also excellent in the light fastness of the recording layer. |
