摘要：
A combination of powder coatings usable in a powder coating method for forming a coating film having visually homogeneous hue by mixing two or more powder coatings of which each color is different. In the combination of powder coatings, each of differences in triboelectric charges of two or more powder coatings is 5.0 μC/g or less. The coating method usable herein includes the step of applying onto a substrate to be coated two or more powder coatings of which each color is different, in which the triboelectric charges are controlled in the above given ranges.
