<P>PROBLEM TO BE SOLVED: To simply and inexpensively provide an optical disk which can fully suppress deformation (warpage) accompanying change of temperature and humidity and is excellent in mechanical strength. <P>SOLUTION: The optical disk is equipped with a protective coat which is made up by polymerizing the ester modified (meta) acrylate resin which is made by carrying out esterification reaction to the (meta) acrylic acid, to a hydroxyl group-containing esterification material comprising photocuring silicone resin containing siloxane skeleton or 2 basic acid having carboxyl group to both ends of the alkylene chain of carbon numbers 1-6, and polyhydric alcohol. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
