Polyamic acid and polyimide |
| abstract |
[PROBLEMS] To provide a resin composition for a display substrate capable of forming a useful polyimide film having a high heat resistance, an appropriate linear expansion coefficient, and a suitable flexibility. [MEANS FOR SOLVING PROBLEMS] A polyamic acid comprising a structural unit represented by the following formula (1) and a structural unit represented by the formula (3) or a structural unit represented by the following formula (2) and a structural unit represented by the formula (4) And a polyimide resin. [Wherein X 1 represents a tetravalent organic group having an aromatic group and two carbonyl groups, Y 1 represents a divalent aromatic group or an aliphatic group, and Y 2 represents a divalent group having a fluorene skeleton An aromatic group, and n and m represent a natural number. |
