<P>PROBLEM TO BE SOLVED: To provide a cationically polymerizable resin composition which is quickly cured by irradiation with light to form a cured product excellent in heat resistance, flexibility, transparency, and dimensional stability. <P>SOLUTION: The cationically polymerizable resin composition comprises a cationically polymerizable resin obtained by the radical polymerization of an oxetane ring-containing (meth)acryloyl compound represented by formula (1) (wherein R<SP POS="POST">1</SP>is hydrogen or a methyl group; R<SP POS="POST">2</SP>is hydrogen or an alkyl group; and A is a 2-20C straight chain or branched chain alkylene group) alone or with another compound having radical polymerizability and an inorganic filler. <P>COPYRIGHT: (C)2013,JPO&INPIT |
