| description | The present invention relates to a tetracarboxylic acid dianhydride, a polyamic acid composition, and a polyimide film. When the tetracarboxylic acid dianhydride is used, a transparent polyimide resin having a low retardation can be provided, and thus a polyimide film useful for a transparent plastic substrate for a display and the like having a low birefringence and a coefficient of thermal expansion can be provided.
본 발명은 테트라카르복실산 이무수물, 폴리아믹산 조성물 및 폴리이미드 필름에 관한 것이다. 상기 테트라카르복실산 이무수물을 사용하면, 저위상차의 투명한 폴리이미드 수지를 제공할 수 있으며, 이에 따라 낮은 복굴절률 및 열팽창 계수를 가져 디스플레이용 투명 플라스틱 기판 등에 유용한 폴리이미드 필름을 제공할 수 있다. |
