To provide a coating method for obtaining a coating film having a gradation pattern, in which the hue is continuously changed, with ≥2 kinds of powder coating compositions and a producing method of the coating film using the coating method.
In the coating method having a process for coating with ≥2 kinds of powder coating compositions each composed of ≥2 kinds of powder coating materials while the weight ratio of the powder coating materials is changed and for obtaining the coating film having the gradation pattern, the powder coating material has a property that each powder coating material alone is not thermally cured at ≤250°C, but is thermally cured at ≤250°C by being mixed and coated with the other powder coating material contained in the same powder coating material composition and at least one kind of the powder coating material has a property of being thermally cured at ≤250°C by being mixed and coated together with at least one kind of the powder coating material contained in the other powder coating composition.
