Abstract
An ionic compound comprising a cationic portion having a hydroxyl group and/or a carboxylic acid group and an anionic portion of the formula (1):[BR]  (1)wherein R may be the same or different and represents a phenyl group substituted with F or CF. Preferably, the anionic portion is [B(CF)], [B(CHCF)]or [B(CHF)]. In other aspects, a radiation polymerization initiator and a resin composition comprising the ionic compound are provided. A resin composition prepared by using the radiation polymerization initiator generates a small amount of outgas during reaction and has excellent reactivity and transparency.
