PROBLEM TO BE SOLVED: To provide a fluororesin-containing aqueous coating composition for polycarbonate capable of forming a coating film which is excellent in adhesiveness to a polycarbonate substrate and maintains excellent adhesiveness even after being held under high-temperature and high-humidity conditions and to provide a method for producing a coated polycarbonate product.SOLUTION: There is provided a fluororesin-containing aqueous coating composition for polycarbonate which comprises: a fluorine-containing copolymer (A) having a hydroxyl group; an isocyanate-based curing agent (B); an oxazoline group-containing polymer (C); and water, wherein the oxazoline group-containing polymer is blended preferably in an amount of 12 to 40 pts.mass based on the total 100 pts.mass of the fluorine-containing copolymer (A) and the isocyanate-based curing agent (B). By using the composition, there may be produced a coated polycarbonate product in which a polycarbonate substrate and a coating film are favorably adhered tightly to each other even under high-temperature and high-humidity conditions. |
