(57) [Abstract] [PROBLEMS] To provide a powder coating method capable of easily forming a coating film that simultaneously exhibits the following functions (1) to (3) without using a solvent or a large-scale apparatus. Functions that exhibit excellent functions (film thickness uniformity, transparency, smoothness, gloss, durability, etc.) when used. A function that exhibits biodegradability at the time of disposal and alkali decomposability at the time of coating film removal processing. A function that makes it easy to remove the coating when the coating is no longer needed. A coating film of aliphatic polyester is formed by coating an aliphatic polyester powder on the surface of a base material by a powder coating method (for example, an electrostatic coating method or a fluid immersion coating method). And powder coating method. |
