Embodiment
[0209] Next, the present invention will be described in detail with reference to examples, but the present invention is not limited by these examples.
Synthetic example 1
[0210] [Synthesis example 1: Synthesis 1 of (A) urethane (meth)acrylate]
[0211] 190.51 g of 2,4-toluene diisocyanate, 268.4 g of isobornyl acrylate, 0.167 g of 2,6-di-tert-butyl-p-cresol, 0.558 g of dibutyltin dilaurate and phen Thiazine (0.056 g) was ice-cooled to a liquid temperature of 10° C. or lower while stirring these substances. 280.14 g of ring-opened polymers of propylene oxide having a number average molecular weight of 2,000 were added, and the mixture was stirred for 2 hours while controlling the liquid temperature to 35° C. or lower to perform a reaction. Next, 47.78 g of hydroxypropyl alkylate was slowly added dropwise, and after stirring for 1 hour while controlling the temperature of the liquid so that the temperature of the liquid did not reach 40° C. or higher, 178.39 g of hydroxyethyl acrylate was dropped so that the temperature did not reach 40° C. or higher. , After completion of the dropping, stirring was continued at a liquid temperature of 70 to 75°...
Synthetic example 2
[0213] [Synthesis Example 2: Synthesis of Urethane (Meth)acrylate]
[0214] 0.240 g of 2,6-di-t-butyl-p-cresol, 428.10 g of 2,4-toluene diisocyanate, and 0.799 g of dibutyltin dilaurate were added to a reaction container equipped with a stirrer, and cooled to 15° C. while stirring. After dropping 570.86 g of hydroxyethyl acrylate while controlling the liquid temperature to 20° C. or lower, it was stirred in a 40° C. water bath for 1 hour. Then, after confirming that a temperature rise was not observed, it stirred at 65 degreeC for 3 hours, and when the residual isocyanate was 0.1 mass % or less, it was regarded as completion|finish of reaction. The obtained urethane (meth)acrylate was designated as UA-2.
[0215] UA-2 has a structure in which 2-hydroxyethyl acrylate is bonded to both ends of 2,4-toluene diisocyanate.
