Procedure

A 2-liter 3-necked flask provided with a stirrer and thermometer were metered in 365.4 parts of 2-hydroxyethyl acrylate, 0.45 parts of di-n-butyltin dilaurate, and 0.4 parts of hydroquinone monomethylether, followed by stirring at 55° C. and adding dropwise in 3 hours, 543.1 parts of a triisocyanate (tradename: Duranate TPA-100, manufactured by Asahi Kasei Kogyo Co., Ltd.), a trimer of hexamethylene diisocyanate and having an isocyanurate skeleton. After the end of the dropwise addition, the reaction was further continued for 8 hours at 70° C. when the viscosity increased so that n-butyl acetate was used to dilute to give a urethane triacrylate (UPA-3) having a final solids concentration of 90% by weight.
