Abstract:
There is provided an optical information recording medium which can meet opposite requirements of enhancement in ink absorption and fixation properties of an image forming layer and suppression and prevention of solid attachment of a printed portion, which has excellent printability to obtain high image quality and an excellent holding property of the printed portion, and which little makes the solid attachment on the printed surface layer occur. At this time, a thick layer can be formed even by the use of a coating solution for the image forming layer. The optical information recording medium has the image forming layer on various layers stacked on a surface of a light transmitting substrate and optically readable signals are recorded or can be recorded therein by the use of laser beams incident on the other surface of the light transmitting substrate, wherein the image forming layer includes an ink absorbing porous layer made of a resin layer containing vapor inorganic particles. A hydrophobic portion is formed in a portion beside the porous layer on the surface of a layer adjacent to the porous layer. An anchor layer is disposed under the porous layer.
