Abstract
A ultraviolet-curable coating composition is disclosed, which comprises a specific ultraviolet-curable polyfunctional (meth)acrylate, a specific urethane-curing polymer, and a specific polyisocyanate compound in a specific compounding ratio and having incorporated therein a photo stabilizer and a photopolymerization initiator. The composition provides a coating film of large thickness in one operation and is sufficiently cured even with non-uniform ultraviolet radiation and the coating film obtained from such a composition fully satisfies various requirements, such as appearance, adhesion, and weathering resistance.
