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 a high peel strength when it is pressure-bonded to a metal foil via 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 0.1 to 100 mol% of carboxy-4,4'-diaminodiphenylmethane and an aromatic tetracarboxylic dianhydride or a derivative thereof. A polyimide film obtained by thermally and / or chemically imidizing this. This polyimide film has high peel strength when it is pressure-bonded to a metal foil via an adhesive. [Selection figure] None |
