Abstract:
One inventive aspect relates to an optical information recording medium which has a high gloss and ensures, even after printing, a gloss substantially equal to that before the printing, and which can increase quality of a printed image. The optical information recording medium has an ink absorbing layer made of a porous film, which is formed on an outermost layer on a surface thereof on the side opposed to a recording/reproducing surface of the optical information recording medium. The optical information recording medium has a surface gloss of the ink absorbing layer is about 25 or more in terms of 60° specular gloss before printing and has a level after the printing which is equal to or higher than a level before the printing.
