Provided is an anti-fouling coating composition capable of producing an anti-fouling film to which dirt and oily components do not readily adhere. The anti-fouling coating composition contains solids comprising components that form the anti-fouling film. The solids contain a resin component (A) comprising at least one of: a fluorine-containing copolymer (a1) having a fluorine-containing segment and a fluorine- and silicon-free acrylic-based segment; and a silicon-containing copolymer (a2) having a silicon-containing segment and a fluorine- and silicon-free acrylic-based segment. The solids furthermore contain a filler (B) having a mean particle diameter of 10-200 nm. L'invention concerne une composition de revêtement antisalissure capable de produire un film antisalissure auquel les salissures et les composants huileux n'adhèrent pas facilement. La composition de revêtement antisalissure contient des solides comprenant des composants qui forment le film antisalissure. Les solides contiennent un composant de résine (A) comprenant : un copolymère contenant du fluor (a1) ayant un segment contenant du fluor et un segment à base d'acrylique exempt de fluor et de silicium; et/ou un copolymère contenant du silicium (a2) ayant un segment contenant du silicium et un segment à base d'acrylique exempt de fluor et de silicium. Les solides contiennent en outre une charge (B) ayant un diamètre moyen de particule de 10 à 200 nm. 本開示は、埃及び油性成分の付着しにくい防汚性皮膜を作製できる防汚性コーティング組成物を提供する。防汚性コーティング組成物は、防汚性皮膜を構成する成分である固形分を含有する。固形分は、フッ素含有セグメントとフッ素及びケイ素を含有しないアクリル系セグメントとを有するフッ素含有共重合体（ａ１）と、ケイ素含有セグメントとフッ素及びケイ素を含有しないアクリル系セグメントとを有するケイ素含有共重合体（ａ２）とのうち、少なくとも一方からなる樹脂成分（Ａ）を含有する。固形分は、平均粒径１０ｎｍ以上２００ｎｍ以下のフィラー（Ｂ）を更に含有する。
