Japanese Patent JP2017039904

A

PROBLEM TO BE SOLVED: To provide a fluorine-containing copolymer aqueous fluid dispersion which provides a coated film excellent in water resistance and which is excellent in storage stability, a fluorine-containing coating composition containing the fluorine-containing copolymer aqueous fluid dispersion and a coating article containing a coated film formed by the fluorine-containing coating composition.SOLUTION: There is provided the fluorine-containing copolymer aqueous fluid dispersion containing a fluorine-containing copolymer (A) having a constitutional unit X based on fluoroolefin and a constitutional unit Y based on a monomer having no fluorine atom, aliphatic acid hydrocarbon with 12 or more carbon atoms (B) and water. In the fluorine-containing copolymer aqueous fluid dispersion, a molar ratio of the constitutional unit X and the constitutional unit Y (constitutional unit X/constitutional unit Y) is 20/80 to 70/30 and content of the aliphatic hydrocarbon (B) to the fluorine-containing copolymer (A) is 0.0001 to 1 mass%.SELECTED DRAWING: None
