This paper describes recent progress in the designing of photoinitiator system for cationic or radical photopolymerization. In this regard, this paper focuses in particular on onium compounds such as iodonium and sulfonium. These compounds generate both acids and radicals upon the irradiation of light. Photoinitiator systems consisting of both onium compounds and several sensitizers are discussed.
