(57) [Abstract] [Purpose] To provide an aqueous fluororesin composition which is excellent in warm water resistance and solvent resistance of the resulting coating film while maintaining the weather resistance which is an excellent property of the aqueous fluororesin composition. provide. The aqueous fluororesin composition contains a fluoropolymer and an acrylic polymer, and the acrylic polymer is An aqueous dispersion of composite polymer particles in which 0.1 to 20 parts by weight of a carbonyl group-containing monomer is copolymerized with 100 parts by weight of the acrylic polymer, and 1 mol of the carbonyl group of the acrylic polymer. On the other hand, it contains a hydrazine derivative having at least two hydrazino groups, which is blended in a ratio of 0.02 to 1 mol. |
