Branched alkoxyphenyl iodonium salt photoinitiators

摘要

Disclosed are C.sub.6 to C.sub.11 branched chain alkoxy monosubstituted diaryl iodonium salts, such as [4-(2-ethylhexyloxy)phenyl] phenyliodonium hexafluoroantimonate. These diaryl iodonium salts are useful as photoinitiators for epoxy containing compounds, especially epoxysilanes.
