Optical disc composed of a plurality of recording layers for recording data and a resin layer between the recording layers

The present invention provides an optical disc whose recording layer can be reliably recognized. An optical disc is composed of a plurality of recording layers for recording data and a resin layer between the recording layers, the resin layer containing fluorine and being cured by ultraviolet rays using a polymerization initiator. The polymerization initiator is a radical polymerizable acetophenone type and contains a carbonyl group. The carbon at the [alpha] position of the carbonyl group is bonded to one oxygen or nitrogen atom, and two alkyl groups that are not cycloalkanes, and the phenyl group containing carbon at the other [alpha] position is unsubstituted or bonded to a -NC4H8O functional group.
