An optical information medium having an ink-accepting layer that may secure a
high-gloss printed surface similar to print image quality of print image on photographic
paper is provided. The optical disk 1 is constituted by sequentially laminating
concavo-convex information pits 3, a recording layer 4, a reflective
layer 5, a protective layer 6, a second printing layer 7,
and an ink-accepting layer 8 on a transparent substrate 2 made of
synthetic resin such as polycarbonate. In the formation of the ink-accepting layer
8, the following proportions of the following constituents in percent by
weight are milled to prepare an ink for printing: 5 to 15% urethane acrylate; 70
to 80% water-soluble monomer; 5 to 15% water-soluble monomer soluble resin; 5 to
15% photopolymerization initiator; 5 to 15% dyestuff fixing agent; and 5% silica.
