摘要： PROBLEM TO BE SOLVED: To provide a transparent and colorless polyimide film that does not cause contour change, such as swelling or dissolving of the film even when immersed in a polar solvent.
SOLUTION: In the polyimide film, the solvent resistance index is within 2%, and the yellowness is 10 or less. The solvent resistance index is defined as a percentage of the difference between the film thickness after the film is immersed in a polar solvent for 10 minutes and the film thickness before the film is immersed in the solvent to the film thickness before the immersion and is represented by the following formula (1). Formula(1) (t
0 -t
1 )/t
0 ×100, wherein t
0 is the film thickness before the film is immersed in the solvent, and t
1 is the film thickness after the film is immersed in a polar solvent for 10 minutes.
