Abstract

Provided is a powder coating composition, whereby a cured film excellent in water resistance, chemical resistance and weather resistance, can be formed by single coating operation, wherein a fluorinated resin layer and a polyester layer are layer-separated in the process of melting and curing the powder coating composition. A powder coating composition comprising a fluorinated resin (A), a polyester polymer (B), a curing agent (C) and an ultraviolet absorber (D), wherein the polyester polymer (B) is a polyester polymer comprising units derived from a Caromatic polybasic carboxylic acid compound and units derived from a Ca polyhydric alcohol compound.
