| 摘要 |
A cationic polymerization type composition includes (A) component: a monofunctional oxetane compound containing one oxetanyl group in the molecule thereof, (B) component: a compound containing two or more cationic ring-opening polymerizable cycle ether residues in the molecule thereof, (C) component: a cationic polymerization initiator having latency, and (D) component: a metal oxide fine particle having a particle size of from 1 to 1,000 nm. The cationic polymerization type composition exhibits good curing properties upon irradiation with active energy rays in air to form a coating film low in residual stress in a cured film and excellent in adhesion, and can impart characteristics such as high surface hardness, abrasion resistance, ultraviolet light shielding properties, heat ray shielding properties, electrical conductivity, and antifungal properties by stably dispersing the component (D).
