Reaction Steps
25 parts of toluene, 25 parts of hexamethylene diisocyanate subjected to isocyanurate modification (“TAKENATE D-170N”), 32 parts of 2-hydroxyethyl acrylate (“LIGHT ESTER HOA”, trade name, produced by KYOEISHA CHEMICAL Co., LTD), 0.02 parts of dibutyltin laurate, and 0.02 parts of hydroquinone monomethyl ether were mixed and the mixture was maintained at 70° C. for 5 hours. Thereafter, 32 parts of toluene was added to obtain a urethane acrylate having a solid content of 50% by weight. The number of repetitions of a caprolactone unit per one residue of the acrylate monomer in the obtained urethane acrylate is 0.
