Urethane (meth) acrylate, method for producing urethane (meth) acrylate, curable composition, cured product, and method for producing cured product

摘要

Provided are a urethane (meth) acrylate capable of achieving high strength and high elongation, a method for producing urethane (meth) acrylate, a curable composition, a cured product, and a method for producing a cured product. A structural unit derived from a polycarbonate diol, a structural unit derived from a polyisocyanate, and a group derived from a (meth) acrylate having a hydroxyl group, Urethane (meth) acrylate in which the polycarbonate diol contains one or more structural units represented by the following formula (1); In the formula, R ¹ , R ² , R ³ and R ⁴ each independently represent an aliphatic hydrocarbon group having 1 to 6 carbon atoms.
