Document Type and Number:
WIPO Patent Application WO/2021/117396
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a cationically curable composition that exhibits an excellent adhesiveness with aluminum die castings, PPS, and the like, while retaining photocurability and low-temperature curability. The present invention is a cationically curable composition that contains components (A) to (E) and contains 12-100 parts by mass of component (E) per a total of 100 parts by mass of component (A) and component (B). Component (A) is an aromatic epoxy resin, component (B) is at least one among a hydrogenated epoxy resin (B1) and an alicyclic epoxy resin (B2), component (C) is a photo-cationic polymerization initiator, component (D) is a thermal cationic polymerization initiator, and component (E) is a polycaprolactone polyol that has at least three hydroxyl groups and a molecular weight of not more than 1,700.
