Abstract Two new hydrogen-donors synthesized from natural products (curcumin and 4-methylumbelliferone) are proposed here as new classes of high performance bio-sourced coinitiators (BHD) for the polymerization of methacrylates under blue light irradiation. In presence of these naturally derived compounds good polymerization performances are reached and good bleaching properties are obtained compared to traditionally used camphorquinone (CQ)-based systems.
