UV-CURABLE COATING COMPOSITION USEFUL AS PRIMARY COATING FOR METALLIC OR PLASTIC SUBSTRATE AND MOLDED ARTICLE COMPRISNG A CURED COATING LAYER FORMED FROM THE SAME

摘要

The present invention relates to a molded article comprising an ultraviolet curable coating composition useful as a coat for a metal or plastic substrate and a cured coating layer formed therefrom, and more particularly, a polyfunctional aliphatic urethane acrylate oligomer having at least six functional groups, a polybutadiene-modified aliphatic urethane acrylic It includes a late oligomer, an acid functional group-containing acrylate oligomer, a monofunctional acrylate monomer, and a photopolymerization initiator, and has excellent adhesion to a metal or plastic substrate, and also includes water resistance, moisture resistance, heat resistance, chemical resistance, and heat and cold resistance. The present invention relates to a molded article comprising an ultraviolet curable coating composition having excellent physical properties and useful as a coat for metal or plastic substrates, in particular for automotive headlamp molded articles.
