Abstract
A polyester obtained from dibasic acids mixture containing 10 to 50 mole-% of endomethylene-tetrahydrophthalic acid and glycols is used in a resin composition for powder coatings. This composition has a good storage stability and when heated in the air at 150.degree. to 220.degree.C exhibits favorable fluidity to form an even coating which quickly hardens to a film with excellent characteristics.
