Abstract

본 발명은 도료용 폴리에스테르 수지에 있어서, 2관능성 카르복실산 그의 에스테르 형성성 유도체 및 탄소수 2∼10의 알킬렌글리콜을 합성한 공중합 폴리에스테르를 지방족 알킬디이소시아네이트로 변성시키므로써, 특히 자동차 도료의 제조에 유용하도록 내한 충격성을 개선시킨 폴리에스테르 수지 조성물에 관한 것이다.In the polyester resin for coatings, in particular, automotive coatings are obtained by modifying a copolyester obtained by synthesizing a difunctional carboxylic acid ester-forming derivative thereof and an alkylene glycol having 2 to 10 carbon atoms with an aliphatic alkyl diisocyanate. It is related with the polyester resin composition which improved the cold-resistant impact so that it may be useful in manufacture.
