URETHANE (METH)ACRYLATE, METHOD FOR MANUFACTURING URETHANE (METH)ACRYLATE, CURABLE COMPOSITION, CURED ARTICLE, AND METHOD FOR MANUFACTURING CURED ARTICLE

摘要

Provided is a urethane (meth)acrylate capable of achieving high strength and high elongation, as well as a method for manufacturing a urethane (meth)acrylate, a curable composition, a cured article, and a method for manufacturing a cured article. The urethane (meth)acrylate contains a structural unit derived from polycarbonate diol, a structural unit derived from polyisocyanate, and a hydroxy group-containing (meth)acrylate-derived group, the polycarbonate diol containing one or more types of structural unit represented by formula (1) wherein each of R¹, R², R³ and R⁴ independently represents an aliphatic hydrocarbon group having 1 to 6 carbon atoms.;
