PROBLEM TO BE SOLVED: To provide a layer separation type powder coating composition with low cost/step-saving and high weather resistance having sufficient weather resistance, also cost effectiveness and capable of forming a coating film with two layers by one coat coating.SOLUTION: The powder coating is obtained by melting/kneading a mixture containing (A) 10-50 pts.mass of a fluorine resin, (B) 10-90 pts.mass of a polyester resin and (C) 10-50 pts.mass of a pigment, and pulverizing it after cooling. In the layer separation type powder coating composition, the (A) fluorine resin and the (B) polyester resin are not made compatible and are not layer-separated by melting-curing the powder coating. |
