Provided is a cationically polymerizable resin composition which has a low viscosity, is easy to work, and is extremely rapidly cured upon irradiation with light to give a cured product excellent in optical transparency, flexibility, thermal stability, and post-heating bendability.
The cationically polymerizable resin composition includes an oxetane-ring-containing vinyl ether compound (A) and/or an alicyclic-epoxy-group-containing vinyl ether compound (B); an oligomer or polymer (C) containing, in the molecule, at least one selected from oxetane group, epoxy group, hydroxyl group, vinyl ether group, and an aliphatic or alicyclic unsaturated hydrocarbon group and having a molecular weight of 500 or more; and an oxetane compound (D) containing no vinyl ether group and having 6 or more carbon atoms.
提供了一种阳离子聚合树脂组合物,具有低粘度、易于操作,并在光照辐射下极快地固化,形成的固化产物具有优异的光学透明度、柔韧性、热稳定性和后热弯曲性。该阳离子聚合树脂组合物包括含氧杂环环氧基乙烯醚化合物(A)和/或含脂环氧基团的乙烯醚化合物(B);分子中含有至少一种氧杂环基、环氧基、羟基、乙烯基醚基和脂肪或脂环烯烃基且分子量为500或更高的低聚物或聚合物(C);以及不含乙烯基醚基且碳原子数为6或更多的氧杂环化合物(D)。
