Abstract: To provide a process for producing a coated article, capable of producing a coated article having a coating film excellent in weather resistance, using a powder coating material.
A process for producing a coated article having a substrate, comprising:
applying a curable powder coating material containing a curable polymer containing no fluorine atom, a curing agent and a pigment to a surface of a substrate, to form a first coating layer composed of the curable powder coating material, then
applying a powder coating material containing a fluorinated polymer and containing no pigment to a surface of the first coating layer, to form a second coating layer composed of the powder coating material, and
heating the first coating layer and the second coating layer simultaneously to form a coating film on the surface of the substrate.

Abstract: To provide a powder coating material capable of forming a coating film that is excellent in weather resistance, processability and impact resistance and that improves corrosion resistance of a substrate (in particular, a substrate made of aluminum or of an aluminum alloy).
A powder coating material comprising a powder of a resin composition, wherein the resin composition comprises a fluorinated polymer (A) having a number average molecular weight of from 10,000 to 50,000 and a fluorine content of at least 10 mass%, a resin (B) having a fluorine content of less than 10 mass% or containing no fluorine atom, a curing agent, a plasticizer having a melting point of from 50 to 150°C and core-shell particles, and wherein the absolute value of the difference between the melting point of the plasticizer and the glass transition temperature of a polymer of a shell portion in the core-shell particles is within 30°C and the content of the plasticizer is from 5 to 25 parts by mass based on 100 parts by mass of the fluorinated polymer (A).
