摘要：
The present invention relates to an active energy ray curable composition for coating optical disc, comprising a urethane (meth)acrylate compound having at least one amide group in the molecule, an ethylenically unsaturated compound other than the urethane (meth)acrylate compound and a photopolymerization initiator; and an optical disc having a cured coating layer obtained by curing the composition.
