Abstract:
Triarylsulfonium salts of formula I or II are useful as initiators for cationic photopolymerizations: wherein Ar1 and Ar2 are independently polycyclic aryl, substituted aryl, heteroaryl, substituted heteroaryl, or aryl or heteroaryl, pendant from a polymer chain; and MtXn− is a complex anion selected from PF6−, SbF6−, AsF6−, GaF6−, BF4−, (C6F5)4B− and CF3SO3− , C9F19SO3− and (CF3SO2)3C−.
