<P>PROBLEM TO BE SOLVED: To provide an optical information medium including a light-transmitting layer superior in water repellency and oil repellency. <P>SOLUTION: The optical information medium includes the light-transmitting layer on an information recording surface of a support substrate with the information recording surface formed on the surface thereof and used so that at least one of recording light and reproducing light is incident thereon through the light-transmitting layer. The light-transmitting layer is made by curing a curable composition containing a (meth) acrylate (A), polydimethylsiloxane (B) including at least two (meth)acryloyl groups at molecule chain ends, and a photopolymerization initiator (C). <P>COPYRIGHT: (C)2009,JPO&INPIT |
