Summary:The present invention relates to a crosslinked polyimide film using a polyhydric amine and a method for manufacturing the same. More specifically, the present invention relates to: a method for manufacturing a crosslinked polyimide film which dissolves an amine monomer in a solvent, adds a hydrid monomer to the solution and placing the same for a period of time to manufacture a polyamic acid, and slowly puts a polyhydric amine monomer to the polyamic acid to mix well together, followed by cross-linking the same to manufacture a polyhydric polyamic acid and imidizing the solution; and the crosslinked polyimide film having improved stability which is manufactured by the manufacturing method. 본 발명은 다가아민을 이용한 가교 폴리이미드 필름 및 이의 제조방법에 관한 것으로서, 보다 상세하게는 아민 단량체를 용매에 녹인 후, 그 용액에 하이드라이드 단량체를 넣고 일정 시간 두어 폴리아믹산을 제조한 다음, 폴리아믹산에 다가아민 단량체를 잘 섞이도록 천천히 넣고 가교하여 다가아민 폴리아믹산을 제조한 후, 이 용액을 이미드화하는 공정을 포함하는 가교 폴리이미드 필름의 제조방법, 및 상기 제조방법으로 제조된 안정성이 향상된 가교 폴리이미드 필름에 관한 것이다.
