Coating composition.

摘要

Disclosed is a coating composition comprising (A) 10 to 70 parts by weight of a poly(meth)acrylate of mono- or polypentaerythritol, (B) 5 to 50 parts by weight of a urethane poly(meth)acrylate having at least two unsaturated double bonds in the molecule, (C) 5 to 50 parts by weight of a poly[(meth)acryloyloxyalkyl] (iso)cyanurate, (D) 2 to 30 parts by weight of an ultraviolet absorber, (E) 0.1 to 10 parts by weight of a photopolymerization initiator, and (F) 0.1 to 5 parts by weight of a hindered amine type light stabilizer, provided that the combined amount of components (A) to (F) is 100 parts by weight. This coating composition can form a crosslinked and cured film having excellent abrasion resistance, surface smoothness, thermal resistance, chemical resistance, durability, weather resistance and adhesion to the substrate.
