摘要:
A non-thermoplastic polyimide film exhibits high adherability without expensive surface treatment and is made from a precursor solution having high storage stability. The non-thermoplastic polyimide film comprises a non-thermoplastic polyimide resin having a block component derived from a thermoplastic polyimide. Preferably, the block component of the thermoplastic polyimide is present in an amount of 20 to 60 mol % of the entire polyimide so that the precursor solution thereof exhibits high storage stability and that the film can exhibit high adherability, in particular, high adherability to polyimide adhesives.
