Abstract

PURPOSE: A powder coating composition self-curable by air drying that contains a specific polyester blocked at least one terminal of the main chain with a monofunctional unsaturated cyclic compound, thus having good coating operability.
CONSTITUTION: The terminals of a polyester prepared from (a) at least one of polycarboxylic acid components containing more than 10 mol% of aromatic polycarboxylic acid such as terephthalic or isophthalic acid and (b) at least one of polyhydric alcohol components are blocked with a monofunctional unsaturated alicyclic compound such as an adduct of ethylene or propylene glycol to dicyclopendiene to form a polyester melting at 30W150°C, which is used as the powder coating. The molar ratio of the monofunctional unsaturated alicyclic compound to the aromatic polycarboxylic acid is preferably 1W85.
