ACTIVE ENERGY RAY-CURABLE COATING COMPOSITION, AND MOLDED ARTICLE HAVING CURED FILM OF THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a coating composition forming a cured film that exhibits excellent weather resistance, abrasion resistance and adhesion to a substrate.

SOLUTION: The active energy ray-curable coating composition comprises the following components (A)-(D), preferably the components (A)-(F): (A) 10-70 mass% of a poly(meth)acrylate of a caprolactone-modified mono- or polypentaerythritol; (B) 5-50 mass% of a polyether-based urethane di(meth)acrylate compound bearing two (meth)acryloyloxy groups; (C) 5-70 mass% of a poly[(meth)acryloyloxyalkyl] (iso)cyanurate; (D) 0.1-10 mass% of a photopolymerization initiator; (E) 1-30 mass% of an ultraviolet absorber; and (F) 0.1-5 mass% of a hindered amine light-stabilizer.
