Front Cover: Nowaday, pyrylium salts could be considerate to be effective initiators for both photochemical and thermal cationic polymerization of epoxy resin. Triphenylpyrylium salt derivatives are the most efficient structures to photopolymerize the resin. Beside, these compounds also exhibit some thermal reactivity at room temperature in the absence of light, a fact opening the way to the development of new dual cure photochemical/thermal initiating system. Further details can be found in the article by David Maréchal, Xavier Allonas,* Maxime Lecompère, Adrien Criqui page 1169. [ABSTRACT FROM AUTHOR]
