CATION-POLYMERIZABLE COMPOSITION

摘要

A cation-polymerizable composition according to the present invention comprises (1) a cation-polymerizable organic substance mixture and (2) an energy ray-sensitive cation polymerization initiator, wherein the cation-polymerizable organic substance mixture (1) contains an aliphatic epoxy compound (1A) and/or an alicyclic epoxy compound (1B) as a cation-polymerizable organic substance. In the cation-polymerizable composition, at least one monofunctional epoxy compound is contained as the aliphatic epoxy compound (1A) or the alicyclic epoxy compound (1B). Alternatively, the cation-polymerizable composition additionally contains an aromatic epoxy compound (1C), wherein at least one monofunctional epoxy compound is contained as the aliphatic epoxy compound (1A), the alicyclic epoxy compound (1B) or the aromatic epoxy compound (1C).
