PURPOSE: A urethane (meth)acrylate and a curable resin composition is provided to obtain sufficient strength, scratch resistance, and cured material with resilience. CONSTITUTION: A urethane (meth)acrylate is obtained by the reaction of polyol including two or more hydroxyl groups per one molecule, a polyisocyanate, and a (meth)acrylate component including a hydroxy group. The functional group number of polyurethane obtained by the reaction of the polyol and the polyisocyanate is 3.0-6.0. A curable resin composition contains the urethane (meth)acrylate and has a cured material the glass transition temperature of which measured by a dynamic viscoelasticity analysis is 0-30 °C. |
