| titleOfInvention | Polyimide resin |
| abstract | The present invention provides a polyimide-based resin capable of forming an optical film with high fracture strain and low thermal expansion coefficient. The polyimide resin of the present invention contains the structural unit represented by formula (1): As Y in formula (1), it includes the structure represented by formula (3) and the structure represented by formula (5): [In formula (3), R 2 to R 5 independently represent a hydrogen atom or a monovalent hydrocarbon group that may have a halogen atom, and n represents an integer of 1 to 4, where at least one benzene having R 2 to R 5 In the ring, at least 3 of R 2 to R 5 are monovalent hydrocarbon groups that may have halogen atoms] In the structural unit represented by the formula (1), the ratio of the structural unit represented by the formula (5) to Y exceeds 30 mol%. |
