Versuchsvorschrift
To a reactor, 53.3 parts by mass of bisphenol-A/ethyleneoxide 2 mole-adduct, 34.0 parts by mass of xylylene diisocyanate, and 93.5 parts by mass of phenoxyethyl acrylate were added and reacted at 80° C. for 5 hours; then, 6.2 parts by mass of 2-hydroxyethyl acrylate and 0.03 parts by mass of urethanizing catalyst were added and reacted at 80° C. for 5 hours, to obtain a urethane acrylate-based oligomer (i.e. a light curable oligomer).
