| 摘要 |
The present invention relates to a cationically polymerizable adhesive including a polyol (A) containing a polyether polyol (a) that has one or more moieties selected from the group consisting of a polyoxyethylene moiety and a polyoxypropylene moiety and has a number-average molecular weight of 300 to 5000; an oxetanyl-group-containing compound (B) containing an oxetanyl-group-containing compound (b) having a molecular weight of 100 to 800; a glycidyl ether (C) containing an aromatic glycidyl ether (c); and a cationic polymerization initiator (D), wherein a content of the polyether polyol (a) is 0.05 to 3 parts by mass with respect to 100 parts by mass of the polyol (A), the oxetanyl-group-containing compound (B), and the glycidyl ether (C) in total. |
