Abstract:
To provide a coating material composition capable of forming a cured film free from flooding or color separation and excellent in weather resistance, as well as a solvent-based coating material, an aqueous coating material, a powder coating material and a coated article, using such a composition. A coating material composition comprising a fluorinated copolymer (A) and a pigment (B), characterized in that the fluorinated copolymer (A) has units represented by the following formula (1) [X and Y are each independently H, F, CF3 or Cl] and units represented by the following formula (2), the number average molecular weight of the fluorinated copolymer (A) is from 10,000 to 100,000, and the content of the pigment (B) is from 20 to 200 parts by mass, per 100 parts by mass of the fluorinated copolymer (A):
