The present invention provides a polyamic acid aqueous solution composition capable of polymerizing polyamic acid in water rather than in an organic solvent, as well as achieving a high imidization rate during low-temperature curing. La présente invention concerne une composition de solution aqueuse d'acide polyamique permettant de polymériser de l'acide polyamique dans de l'eau plutôt que dans un solvant organique et d'obtenir un taux d'imidation élevé pendant le durcissement à basse température. 본 출원은 유기 용매가 아닌 물에서 폴리아믹산 중합 가능할 뿐 아니라, 저온 경화 시 높은 이미드화율을 구현하는 폴리아믹산 수용액 조성물을 제공한다.
