Retadation film and preparing method for retadation film |
| abstract |
The present invention relates to a base film comprising a negative retardation material; A primer layer formed on at least one surface of the base film; And a coating layer comprising a polyimide copolymer formed on the primer layer and comprising a repeating unit represented by the following formula (1), and a method for producing the same. [Chemical Formula 1] Wherein X 1 is a divalent organic group derived from an alicyclic or aromatic acid dianhydride containing an ester group or an ether group; X 2 is a divalent organic group derived from an acid dianhydride different from X 1 ; Q 1 and Q 2 are each independently a divalent organic group derived from a diamine; Wherein a, b, c and d represent the molar ratio of the respective repeating units, a + b + c + d = 1, 0.1? A + b? 1 and 0? C + d? 0.9. |
