titleOfInvention | Optical film, flexible display device and polyamide-imide resin |
abstract | Provided is an optical film having a high modulus of elasticity and surface hardness. The optical film comprises a polyamide-imide resin containing a structural unit represented by formula (1): (In formula (1), R 1 and R 2 independently represent a C1-12 alkyl group, a C1-12 alkoxy group, a C6-12 aryl group, a C6-12 aryloxy group, a C1-12 carbonyl group, a C1-12 oxycarbonyl group or a halogen group, where the hydrogen atoms contained in R 1 and R 2 are may each be independently substituted with a halogen atom, a C1-4 alkyl group, a C1-4 alkoxy group, a hydroxyl group, or a carboxyl group, and V represents a single bond, -O-, a diphenylmethylene group, a C1-12 linear, branched or alicyclic divalent hydrocarbon group, -SO 2 -, -S-, -CO-, -PO-, PO 2 -, -N(R 30 )- or -Si(R 31 ) 2 -, where the hydrogen atoms contained in said hydrocarbon group may each be independently substituted with a halogen atom, and R 30 and R 31 each independently represent hydrogen atoms or C1-12 alkyl groups which may be substituted with halogen atoms, m represents an integer of 0-2, n represents an integer of 1-4, p represents an integer of 0-4, and q represents an integer of 0-4) and a structural unit represented by formula (2): (in formula (2) X represents a divalent organic group and Y represents a tetravalent organic group). |
