摘要： A novel polyester type powder coating composition which includes a specific self-hardening polyester of air-hardening type comprising as main ester-constituting monomer units, (1) at least one polycarboxylic acid component containing at least 10 mole %, based on the polycarboxylic acid component, of at least one aromatic polycarboxylic acid component (A) and (2) at least one polyhydric alcohol component, having in its main chain at least one terminal blocked with a monofunctional unsaturated alicyclic compound component (B) and having a softening point of 30.degree. to 150.degree. C. This composition is excellent in storage stability and adaptability to either thin coating or thick coating, and when it is applied onto an article to be coated and baked at a temperature of 170.degree. to 230.degree. C. for 5 to 30 minutes, a coating excellent in appearance, mechanical strength, gloss and reflection sharpness can be formed advantageously without generating undesired gases at the baking.
摘要翻译：一种新型聚酯型粉末涂料组合物，其包含包含作为主要酯构成单体单元的空气硬化型的特定自硬化聚酯，（1）至少一种含有至少10摩尔％的多元羧酸组分，基于多元羧酸组分，至少一种芳族多元羧酸组分（A）和（2）至少一种多元醇组分，其主链中至少有一个末端用单官能不饱和脂环族化合物组分（B）封端并具有软化点 30℃至150℃。该组合物的储存稳定性和薄涂层或厚涂层的适应性优异，并且当其施加到待涂覆的制品上并在170℃至230℃的温度下烘烤5次至30分钟，可以有利地形成外观优异，机械强度，光泽度和反射锐度的涂层，而不会在烘烤时产生不期望的气体。

摘要： 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.
摘要翻译：在粉末涂料用树脂组合物中使用由含有10〜50摩尔％的内亚甲基 - 四氢邻苯二甲酸和二醇的二元酸混合得到的聚酯。该组合物具有良好的储存稳定性，并且在空气中在150〜220℃下加热时，表现出良好的流动性，形成均匀的涂层，其能够快速地硬化到具有优异特性的膜。
