PROBLEM TO BE SOLVED: To provide a compound having excellent antifouling and water repellent properties, moreover, stable against water. SOLUTION: A composition comprising a copolymer and water is provided. In the composition, the copolymer includes a reactive silyl group-containing (meth)acrylate ester (A), (meth)acrylic acid or an ester thereof (B), a siloxane-containing (meth)acrylate ester (C), and an amine-containing (meth)acrylate ester (D) as constituent monomers, wherein the content of the monomer (A) is≥0.1 mass% to <25.0 mass%, and is produced by solution polymerization, and the copolymer concentration in the composition is equal to or less than a specific amount.
