摘要 |
<p>Disclosed is a low-cost polyimide film having excellent heat resistance, colorless transparency, formability and optical characteristics. The film contains a polyamic acid and/or a polyimide which is obtained by reacting (A) at least one acyl compound selected from the group consisting of 2,3,5-tricarboxycyclopentylacetic acid, 2,3,5-tricarboxycyclopentylacetic acid dianhydride and reactive derivatives of those, and (B) a specific aromatic imino-forming compound in such a manner that the molar ratio between (A) the acyl compound and (B) the aromatic imino-forming compound is within the range from 1.000:0.960 to 1.000:0.995.</p> |
