Abstract : This paper is devoted to study two acridone derivatives (A-2DPA and A-2PTz). These acridone compounds are synthesized and proposed as high performance visible light photoinitiators, in the presence of an iodonium salt or/and an amine (NPG or EDB), for both the free radical polymerization of (meth)acrylates and the cationic polymerization of epoxides upon irradiation with LED@405 nm. Excellent polymerization initiating abilities are found, and high final monomer conversions are obtained. A full picture of the involved photochemical mechanisms is provided. This paper is also concerned with the use of these acridone-based systems in new 3D printing resins. Finally, the usage of the new acridone derivatives for photopolyrners with low migration properties is particularly outlined.
