Abstract

본 발명은 도장강팡용 도료에 유용한 공중합 폴리에스테르 수지에 관한 것으로서, 더욱 상세하게는 산 성분과 다가 알콜 성분이 함유된 공종합 폴리에스테르 수지에 산(acid)성분으로서 3관능성 산과 지방족 또는 지환족 디카르복실산을, 그리고 다가 알콜 성분으로서 비스페놀 A의 알킬렌 옥사이드기 부가물을 새로이 함유시킴으로써 프레스 가공성, 내식성, 저온 경화성 및 내화학성이 우수한 도장간판이나 선박용 증방식 도료 또는 바인더 수지등에 매우 유용한 공중합 폴리에스테르 수지에 관한 것이다.The present invention relates to a copolyester resin useful for coating steel coatings, more particularly trifunctional acid and aliphatic or cycloaliphatic as an acid component in a co-polyester resin containing an acid component and a polyhydric alcohol component. A new copolymer containing dicarboxylic acid and an alkylene oxide group adduct of bisphenol A as a polyhydric alcohol component, which is very useful for coating signboards, marine thickening paints or binder resins, which are excellent in press workability, corrosion resistance, low temperature curing and chemical resistance. It relates to a polyester resin.
