PROBLEM TO BE SOLVED: To provide an ultraviolet-curable composition that can be suitably used for forming a pattern (printed part) excellent in glossiness and abrasion resistance, and to provide a recorded matter having a pattern excellent in glossiness and abrasion resistance.SOLUTION: The ultraviolet-curable composition of the present invention comprises a polymerizable compound, a metal powder, and a fluorine-containing powder, in which the content percentage of the fluorine-containing powder is 0.010 mass% or more and 5.0 mass% or less. Particles constituting the fluorine-containing powder preferably comprise at least either particles constituted by a fluorine-based polymer or inorganic fine particles treated with a fluorine-based surface treatment agent. The metal powder preferably comprises particles surface-treated with a fluorine-based surface treatment agent as constituent particles.SELECTED DRAWING: None 【課題】光沢感および耐擦性に優れたパターン（印刷部）の形成に好適に用いることのできる紫外線硬化型組成物を提供すること、また、光沢感および耐擦性に優れたパターンを有する記録物を提供すること。【解決手段】本発明の紫外線硬化型組成物は、重合性化合物と、金属粉末と、フッ素含有粉末とを含み、前記フッ素含有粉末の含有率が０．０１０質量％以上５．０質量％以下であることを特徴とする。前記フッ素含有粉末の構成粒子は、フッ素系高分子で構成された粒子、フッ素系表面処理剤で処理された無機微粒子のうち少なくとも一方を含むものであることが好ましい。前記金属粉末は、構成粒子としてフッ素系表面処理剤で表面処理されたものを含むものであることが好ましい。【選択図】なし
