Procedure
Into a flask similar to the flask in Synthesis Example 1 were charged 62.6 parts of toluene and 7.3 parts of a polyoxyethylene cetyl ether (“NONION P-205”, a trade name of NOF Corporation), followed by heating of the mixture to 40° C. After the confirmation of thorough dissolution of the polyoxyethylene cetyl ether, 50 parts of hexamethylene diisocyanate subjected to isocyanurate modification (TAKENATE D-170N) were charged and the mixture was heated to 70° C. After 30 minutes of the reaction at the same temperature, 0.02 parts of dibutyltin laurate were charged. After the mixture was maintained at the same temperature for 3 hours, 88.8 parts of polycaprolactone-modified hydroxyethyl acrylate (PLACCEL FA2D), 0.02 parts of dibutyltin laurate, and 0.02 parts of hydroquinone monomethyl ether were charged. The mixture was maintained at 70° C. for 3 hours to complete the reaction, and 83.5 parts of toluene were added to obtain a urethane acrylate containing 50% by weight of solid.
