| 摘要 |
The objective of the present invention is to provide: a cationic polymerization initiator which enables an epoxy resin composition to achieve a good balance between excellent curability and storage stability; and an epoxy resin composition which contains this cationic polymerization initiator. A cationic polymerization initiator according to the present invention is characterized by being represented by general formula (1). (In general formula (1), R1 represents a hydroxyl group, an R5O group, an R5COO group, an R5NHCOO group or an R5OCOO group; each of R2, R3 and R4 independently represents a hydrogen atom or an alkyl group having 1-6 carbon atoms; and R5 represents an optionally substituted aromatic hydrocarbon group or aliphatic hydrocarbon group.) |
