Abstract

Provided is a cationically polymerizable resin which is rapidly cured upon irradiation with light and forms a cured product excellent in flexibility and thermal stability. The cationically polymerizable resin is obtained through radical polymerization of an oxetane-ring-containing (meth)acryloyl compound represented by following Formula (1) alone or in combination with another radically polymerizable compound. In the formula, R¹ represents hydrogen atom or methyl group; R² represents hydrogen atom or an alkyl group; and “A” represents a linear or branched chain alkylene group having 2 to 20 carbon atoms.

Claims
