Abstract
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.
