Based on our previous work, we propose here four new hydrogen donors to replace aromatic amines currently used in the camphorquinone/amine photoinitiating system. These new proposed coinitiators are used in three component initiating systems for the polymerization of methacrylates under blue light irradiation (LED@477 nm). These compounds act both as coinitiators and copolymerizable monomers. Therefore, they are much less subject to migration. Bleaching properties are also studied, and good results are obtained after polymerization.
