Polyimide resin and polyimide film |
| abstract |
Disclosed are a polyimide resin containing a structural unit represented by the following formula (1-1), and a polyimide film containing a structural unit represented by the following formula (1-2) and having a thickness of 10 to 50 μm. R 1 and R 2 in the formula (1-1) each independently represent any group of the following formulae (i) to (iv), R 1 and R 2 in the formula (1-2) each independently represent a group of the following formula (i) or formula (ii), and in these formulae, * bonds to the carbon with * in the formula (1-1) and the formula (1-2) and ** bonds to the carbon with ** in the formula (1-1) and the formula (1-2). A polyimide resin capable of forming a polyimide film excellent in transparency and having a low coefficient of linear thermal expansion, and a polyimide film having a lower coefficient of linear thermal expansion are provided. |
