Aryl ketone - containing iodonium salts, process for their preparation and iodonium salts of organic resin compositions containing such photopolymerizable

摘要

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.
