| titleOfInvention | Tetracarboxylic dianhydride, polyamic acid and polyimide |
| abstract | An object of the present invention is to provide a polyimide which is excellent in solvent solubility and exhibits a high refractive index. n n The present inventor found that the above problem can be solved by a polyimide which is produced from a tetracarboxylic acid dianhydride having a fluorene skeleton, an ether group and an ester group represented by the following formula (1), which is not only excellent in solvent solubility and having a high refractive index, but also has excellent toughness in spite of having a rigid structure like a fluorene skeleton. |
