A coating composition forming a abrasion resistant coating comprising (A) an ultraviolet-curable silicone prepared by chemically modifying particulate colloidal silica with a specific silane compound, (B) a monomer mixture comprising a (meth)acrylate having a specific isocyanate skeleton and a urethane poly(meth)acrylate having an alicyclic skeleton, and (C) a photo-polymerization initiator. By using a urethane poly(meth)acrylate having an alicyclic skeleton as part of the component (B) and the component (A) having an enhanced reactivity of chemical modification, the compatibility of the component (A) with the component (B) is improved to give a cured coating with excellent wear resistance, weather resistance and durability.
