Zusammenfassung:	To provide an aqueous composition that can form a coating film that has its appearance not impaired even with a deep color base material, shows excellent crack prevention and water-holding capacity, and can maintain its appearance, stain resistance, sealing stain resistance and bio-stain resistance at high levels for long time.SOLUTION: An aqueous composition has: inorganic oxide B having no photocatalytic activity; and inorganic oxide C having photocatalytic activity. The inorganic oxide B having no photocatalytic activity has a number average particle size of more than 30 nm to 160 nm or less.SELECTED DRAWING: None 【課題】濃色基材でも外観を損なわず、塗膜のクラック及び塗膜の保水性が良好で、長期に亘って、外観、耐汚染性、シーリング汚染性及び耐生物汚染性を高いレベルで維持できる塗膜が形成可能な水系組成物を提供する。【解決手段】光触媒活性を有しない無機酸化物Ｂと、光触媒活性を有する無機酸化物Ｃと、を含有し、前記光触媒活性を有しない無機酸化物Ｂの数平均粒子径が３０ｎｍ超１６０ｎｍ以下である、水系組成物。【選択図】なし
