Photocurable blends of 2-Methoxytetrahydropyran and cycloaliphatic epoxides.

摘要

Radiation-curable compositions comprising combinations of cycloaliphatic epoxides and cyclic ethers such as cycloaliphatic ethers cure rapidly when initiated by photoinitiators which form cationic catalysts when irradiated with e.g., ultraviolet light. The compositions can also contain other ingredients including poly(active hydrogen) compounds, vinyl ethers (linear and cyclic), glycidyl ethers, poly(vinyl halides), and polylactones. Radiation-cured coatings can be prepared from the compositions, using reduced quantities of the photoinitiator.
