Abstract
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.
