The photoinitiating systems ( PIS ) usable in free radical photopolymerization are briefly reviewed. Apart conventional Type I and Type II photoinitiators, three‐component PIS exhibiting a photocyclic behavior are discussed. The mechanisms of photoreaction are presented, highlighting the role of a redox additive which reacts with the photoinitiator photoproduct. Recent applications in holography recording are described showing that the selection of a PIS plays a crucial role in this application.
