The present invention provides a polyvinyl acetal powder coating material capable of forming a coating film having a highly smooth surface, being less susceptible to yellowing when exposed to heat, and being suitable for working such as bending of a coated article. The present invention is a polyvinyl acetal powder coating material including: a polyvinyl acetal resin; and 0.02 to 5% by weight of an antioxidant relative to the polyvinyl acetal resin. The antioxidant has a molecular weight of 380 to 1000 and a melting point of 80 to 230° C. It is preferable that the molecular weight of the antioxidant be 400 to 1000. |
