COATING COMPOSITION FORMING WEAR-RESISTANT COAT AND ARTICLE COVERED WITH THE COAT

摘要

A coating composition forming a wear-resistant coat which comprises (A) an ultraviolet-curing silicone prepared by chemically modifying particulate colloidal silica with a specific silane compound, (B) a monomer mixture comprising a (meth)acrylate having a specific isocyanurate skeleton and a urethane poly(meth)acrylate having an alicyclic skeleton, and (C) a photo-polymerization initiator. By virtue of the use of a urethane poly(meth)acrylate having an alicyclic skeleton as part of the component (B) and the use of the component (A) having an enhanced degree of chemical modification, the compatibility of the component (A) with the component (B) is so improved as to give a hardened coat excellent in wear resistance, weathering resistance and endurance.
