PROBLEM TO BE SOLVED: To provide a photo-cationically polymerizable composition, rapidly cationically polymerizing by light irradiation and becoming a cured product exhibiting excellent elongation and adhesive force to the variety of materials. SOLUTION: This photo-cationically polymerizable composition contains the photo-cationically polymerizable compound, a CTBN-modified epoxy-based compound and a photo-cationic polymerization catalyst. In the photo-cationically polymerizable composition, the CTBN-modified epoxy-based compound is a bisphenol A type epoxy resin. In the photo-cationically polymerizable composition, the epoxy equivalent of the CTBN-modified epoxy-based compound is 200-500. The photo-cationically polymerizable composition is exposed to light containing at least 300-800 nm wavelength components. Also, the photo-cationically polymerizable composition is used for joining materials having≤10 % light transmission. COPYRIGHT: (C)2005,JPO&NCIPI
