Ultraviolet-curable composition and method for patterning the cured product therefrom |
摘要 |
This invention pertains to a curable composition comprising a N-substituted 4-(o-nitrophenyl)dihydropyridine (a compound that generates base under the action of ultraviolet radiation) and a silanol-containing polymer that condenses under the action of the base generated to form a siloxane bond. The compositions of the instant invention cure by exposure to ultraviolet radiation. Cured patterns may be formed from the curable composition by interposing a mask between a film of the said composition and the radiation source during UV exposure, then dissolving and removing the uncured composition to form a pattern, and thereafter heating the residual material. The compositions can be cured by low-strength ultraviolet radiation and produce a highly heat-resistant cured product.
