Polyamic acid, polyimide film comprising the same, method for producing the same, and flexible circuit board |
| abstract |
PROBLEM TO BE SOLVED: To provide a polyimide film having high peel strength when it is pressure-bonded to a metal foil through an adhesive, a method for easily producing the film, and a circuit board using the film. SOLUTION: A polyamic acid synthesized from an aromatic diamine containing carboxy-4,4'-diaminobiphenyl in a proportion of 1 to 100 mol% and an aromatic tetracarboxylic dianhydride or a derivative thereof, and A polyimide film obtained by thermally and / or chemically imidizing a polymer. [Selection figure] None |
