The present application provides a polyamic acid aqueous solution composition enabling polyamic acid to be polymerized in water rather than in an organic solvent, and allowing high imidization to be implemented during low temperature curing. La présente demande concerne une composition de solution aqueuse d'acide polyamique permettant la polymérisation d'acide polyamique dans de l'eau plutôt que dans un solvant organique, et permettant la mise en œuvre d'une imidisation élevée pendant un 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.
