A resin powder containing an aromatic polyetherketone resin (e.g., a polyetheretherketone) is deformed into a plate-like form, and the resulting powder is used as a resin powder for a coating material. The plate-like resin powder may have an average thickness of, for example, not more than 2 μm. The coating material may contain a dispersing agent or may be dispersed in a dispersion medium, such as water. The coating material may particularly be used as a coating material for covering a metal substrate. The plate-like resin powder, which comprise an aromatic polyetherketone resin, allows formation of a coating layer which has a high adhesion to a substrate and in which the generation of pinholes is efficiently prevented or reduced.
A plate-shaped resin powder comprising an aromatic polyetherketone resin and having an average thickness of not more than 2 μm, an average diameter of 7 to 20 μm determined from an electron micrograph, a ratio of the average thickness and an average major axis of 1/3 to 1/50 in the former/the latter determined from an electron micrograph, and a mode diameter of 15 to 30 μm determined by a light-scattering method, wherein a proportion of the resin powder having the mode diameter is 1 to 20% determined by a light-scattering method based on a total amount of the resin powder.
The plate-shaped resin powder according to claim wherein the aromatic polyetherketone comprises a polyetheretherketone.
