titleOfInvention |
Polyimide precursor solution and a laminate of polyimide film using same |
abstract |
The present invention provides a polyimide precursor composition having excellent storage stability of a solution at room temperature by providing a polyimide precursor solution containing an additive having a structure of Formula 1 with less reactivity with a polyamic acid structure that is a polyimide precursor. do. In addition, the polyimide film prepared from the polyimide precursor composition has excellent adhesion to the inorganic film layer, and thus provides a polyimide film layered product in which excitation does not occur at the interface between the inorganic film layer and the polyimide film in a subsequent process. |
