<p>The purpose of the present invention is to provide a radical-curable resin composition that has low odor and excellent curing characteristics at normal temperature, and in which tensile elongation is enhanced while tensile strength is maintained. The present invention provides a radical-curable resin composition characterized in comprising: a urethane (meth)acrylate resin (1) obtained by reacting a polyester polyol (A) having a number-average molecular weight of 2,500 to 7,000, and a polyisocyanate (B) to obtain an isocyanate-terminated urethane pre-polymer (C), then reacting with a hydroxyl-containing (meth)acryloyl compound (D); and a radical-curable unsaturated monomer (2) having a molecular weight of 200 to 500.</p> |
