文摘
Acridinediones (AD) are attractive dyes exhibiting a strong absorption at about 400 nm. When used in the presence of a silane and an iodonium salt, they efficiently initiate the free radical promoted cationic photopolymerization of an epoxide under air and upon a xenon lamp, a laser diode or sunlight exposure. The mechanism analyzed by ESR and laser flash photolysis is discussed and opens a new way for the design of such three-component systems.
