    摘要： An optical information recording medium achieving stable recording and reading characteristics and having good storage stability including light resistance and heat resistance by preventing colorants contained in a recording layer therein from being decomposed, and also an optical information recording medium that can be individually differentiated from others by outward appearance. The optical information recording medium includes a substrate having successively disposed thereon at least a light-reflective layer, a recording layer on which information is recorded by laser light of a wavelength no longer than 500 nm, and a cover layer containing a UV absorbent that blocks out light of a wavelength no longer than 400 nm and/or a dye that blocks out light of a wavelength no shorter than 500 nm. A second substrate may be disposed opposite to a side of the optical information recording medium that is irradiated with light and may be colored.
