<p><P>PROBLEM TO BE SOLVED: To provide an adamantane copolymer resin giving a cured product with excellent optical characteristics such as transparency and light resistance, durability such as long-term heat resistance, and electrical characteristic such as dielectric constant. <P>SOLUTION: The adamantane copolymer resin is a copolymer comprising a constitutional unit derived from a (meth)acrylic monomer (A) having a cationic polymerizable functional group, and a constitutional unit derived from a (meth)acrylic monomer (B) having an adamantane structure. In this copolymer, a molar ratio of the constitutional unit derived from the monomer (A) to the constitutional unit derived from the monomer (B) is 0.1-20, and weight-average molecular weight is 1,000-10,000. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
