Abstract

Abstract: The photo-initiation activity of two kinds of cationic initiators, sulphonium salts and aryl cyclopentadienylferrocenium salts, and their composites with free radical initiators has been studied in the present paper. The enhanced initiation efficiency of aryl cyclopentadi-enylferrocenium salts by the strong oxidant cumene hydroperoxide and the enhanced crosslinking of cationic curing systems by the addition of suitable amount of polyfunctional alcohols are also discussed.

Key words: cationic initiator, free radical initiator, dual photocuring, coating, adhesive
