In a cured product having a thickness of 60 μm obtained from an actinic energy ray-curable composition of the present invention, when a scratch mark is made at a vertical load of 235 mN using a diamond indenter with a tip diameter of 15 μm, the scratch mark is repaired by a self-repairing ability under an atmosphere at 25° C. and at a relative humidity of 50%. Therefore, the actinic energy ray-curable composition is useful as coating agents or paints for products where scratch resistance is required.
在从本发明的光致固化组合物获得的厚度为60μm的固化产品中,当使用尖端直径为15μm的
金刚石压头以垂直负载235mN制作划痕时,在25℃和相对湿度为50%的环境下,划痕会通过自修复能力得到修复。因此,该光致固化组合物可用作需要耐刮擦性的涂料或涂料的产品。
