PROBLEM TO BE SOLVED: To provide a coating film which develops an iris color pattern even when tin or indium is used as a material for metal vapor-deposited film on the coating film, and an ultraviolet-curable coating composition which forms the coating film.SOLUTION: An ultraviolet-curable resin composition contains: an acrylate oligomer (A); one or both of an acrylate oligomer (B) different from the acrylate oligomer (A) and a thermosetting acrylic resin (F); and a photopolymerization initiator (C). A coating film after coating and curing of the composition has a sea-island structure formed at least on the coating surface, in which 50 or more islands are present within a square region of 1,000 μm×1,000 μm. |
