METHOD FOR PRODUCING POLYIMIDE FILM AND POLYAMIC ACID SOLUTION COMPOSITION |
| 摘要 |
<p>Disclosed is a polyamic acid solution composition which is obtained by introducing a specific chemical structure into a polyamic acid at a ratio within a specific range. The polyamic acid has a chemical structure composed of a 3,3',4,4'-biphenyltetracarboxylic acid component and/or a pyromellitic acid component, and a paraphenylenediamine component. Also disclosed is a method for producing a polyimide film wherein the polyamic acid solution composition is coated over a base and the thus-formed coating film is subjected to a heat treatment.</p> |
