Abstract: A photoinitiator of Formula I includes a benzophenone moiety, a nitrogen-containing moiety (NCM) covalently bonded to the benzophenone moiety, and an unsaturated polymerizable moiety (PM) covalently bonded to the nitrogen-containing moiety. The unsaturated polymerizable moiety includes an acrylate group or a methacrylate group.
