ORIENTED-FILM-FORMING COMPOSITION |
摘要 |
Provided is an oriented-film-forming composition that can give a laminated body which has a substrate, an oriented film and an optically anisotropic film and which is excellent in heat resistance and light resistance. The oriented-film-forming composition is a composition including an oriented-film-forming material and an antioxidant. The antioxidant is preferably a phenolic antioxidant. The oriented-film-forming material preferably contains at least one selected from the group consisting of polyimides, polyamides and polyamic acids. The composition preferably satisfies Mw(A)/Mw(B)>0.85 wherein Mw(B) represents the weight-average molecular weight of the oriented-film-forming material after the composition is heated at 100° C. for 1 hour, and Mw(A) represents that of the same material before the heating. |
