Abstract
In the thermosetting powder coating composition prepared by a combination use of a fluorine-containing polymer and a polyester polymer and containing a curing agent, the fluorine-containing polymer (A) comprising a fluoroolefin unit and a vinyl ester unit and having a crosslinkable reactive group is used as the fluorine-containing polymer or the polyester polymer (I) containing isophthalic acid and/or 1,4-cyclohexane dicarboxylic acid as essential components and having a crosslinkable reactive group is used as the polyester polymer. By the use of this composition, weather resistance and an appearance of a coating film, for example, gloss and smoothness which are conflicting properties in the thermosetting powder coating composition can be enhanced and well balanced.
