Abstract

Adamantane derivatives in which two (meth)acryloyloxyalkyl groups are bonded with an adamantane ring through ester groups, adamantane derivatives in which two adamantane rings are bonded through an alkylene group and two urethane bonds, which two adamantane rings each have a (meth)acryloyloxy group bonded thereto directly or through a coupling group, and adamantane derivatives each having a structure in which a group containing an adamantane ring hangs on the alkylene group of an alkylene glycol di(meth)acrylate. The compounds are useful as dental materials intermediates therefor, and as intermediates for optical materials such as lenses.
