Abstract
An optical information recording medium is ccccosed of a transparent substrate, a recording dye layer on which information is recordable by irradiation with a laser beam, a light-reflecting layer, a protective layer, and a water-absorbing layer overlaid in order, in which the water-absorbing layer is made of water-absorbing particles and a UV curing resin and has a surface having no wave whose period and height are less than 500 μm and more than 25 μm, respectively, and having a contact angle of less than 90°.
