| titleOfInvention | Optical Film and Flexible Display |
| abstract | Provided is an optical film excellent in appearance quality that does not damage the appearance quality of the optical film even when it comes into contact with alcohol. The structural unit represented by Formula (a) derived from a tetracarboxylic acid compound, the structural unit represented by Formula (b) derived from a dicarboxylic acid compound, and the structural unit represented by Formula (c) derived from a diamine compound : [In formula (a), Y represents a tetravalent organic group, in formula (b), Z represents a divalent organic group, in formula (c), X represents a divalent organic group, and R c is independent of each other An optical film comprising a polyamideimide-based resin having at least a hydrogen atom or a bond, and * denotes a bond; wherein the polyamideimide-based resin is a structural unit derived from the tetracarboxylic acid compound. Y in formula (a) as Formula (1): [in formula (1), R a is each independently a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, or an alkoxy group having 6 to 12 carbon atoms represents an aryl group of , the hydrogen atoms contained in R a may, independently of each other, be substituted with a halogen atom, n represents an integer of 0 to 2, * represents a bond, R * represents a When represented by formula (1), a bond is represented, and when Z is represented by formula (1), R a is represented] as a structural unit (a1) and a structural unit derived from the dicarboxylic acid compound. Z in Formula (b) contains at least 1 structural unit selected from the group which consists of structural unit (b1) represented by Formula (1), L * a * b * in reflected light measurement of the said optical film in the color difference measurement of L 1 * and surface brightness based on the color coordinate system, the absolute value of the difference between the brightness L 2 * based on L * a * b * color system of such the optical film after the ethanol and 40 minutes in contact ΔL * is 0.5 or less, an optical film. |
