(57) 【Abstract】 PROBLEM TO BE SOLVED: To prevent the base or the already-painted surface made of a petroleum solvent-soluble resin from being damaged, a wide range of painted surfaces can be overcoated, but the chemical resistance and water resistance of the coating film Provided is a coating composition having physical properties inherent to a fluororesin such as weather resistance. SOLUTION: Fluoroolefin 30 to 55 mol%, Monomer consisting of 8 to 25 mol% of a hydroxy group-containing polymerizable compound, 0.1 to 20 mol% of a linear unsaturated fatty acid having 10 or more carbon atoms, and 15 to 50 mol% of another copolymerizable vinyl compound Resin OH value obtained by polymerizing A fluorine-based copolymer soluble in a petroleum-based solvent of 0 to 120 mgKOH / g, wherein the polymerization is carried out in a petroleum-based solvent containing 40% by weight or more of an aromatic hydrocarbon having 9 or more carbon atoms. And a fluororesin coating composition prepared from the fluorocopolymer. |
