ABSTRACT:
Triarylsulfonium salts of formula I or II are useful as initiators for cationic photopolymerizations:wherein Ar1and Ar2are 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 CF3SO2)3C−.
