Abstract:
1. A composition for flexible substrate, comprising: a polymer (A) selected from the group consisting of polyamic acid resin, polyimide resin and any combination thereof, wherein an imidization ratio of the polyimide resin is 50% to 93%, the polymer (A) is obtained by reacting a mixture that includes a tetracarboxylic dianhydride component and a diamine component, the tetracarboxylic dianhydride component at least includes bicyclic alicyclic tetracarboxylic dianhydride compound, and the bicyclic alicyclic tetracarboxylic dianhydride compound has a tetravalent bridged hydrocarbon group with 7 to 9 of the total carbon atom number; an inorganic oxide particle (B); a silane compound containing an amino group (C); a solvent (D); and a compound (E) of Formula (I): wherein the R wherein based on a usage amount of the polymer (A) as 100 parts by weight, a usage amount of the compound (E) is 0.1 parts by weight to 3 parts by weight.
