Abstract
Aryliodonium salts resulting from the condensation of aryliodosotosylates and aryl ketones are provided which are used as photoinitiators to effect deep section UV cures. Deep section photopolymerizable organic materials are also provided which can be used as encapsulating agents to encapsulate a wide variety of electronic components.
Claims6

- (A) 100 parts of a cationically polymerizable organic material and
- (B) an effective amount of an aryl ketone containing iodonium salt of the formula,
- [RR.sup.1 I].sup.+ X.sup.31
- where R is a C.sub.(6-13) monovalent aromatic hydrocarbon radical or halo substituted monovalent aromatic hydrocarbon radical and R.sup.1 is a monovalent aryl ketone group and X.sup.- is a counter ion.
