Abstract:
A film and a flexible metal-clad laminate obtained with the film. The laminate is improved in post-moisture absorption solderability. The film comprises a heat-resistant polyimide film and, disposed on at least one side thereof, an adhesive layer containing a thermoplastic polyimide. It is characterized in that the thermoplastic polyimide contained in the adhesive layer has crystallinity and that the film, when analyzed with a differential scanning calorimeter, has an endothermic peak attributable to the melting of the crystalline thermoplastic polyimide, the absolute value of the area of the peak being 4.0 mJ/mg or larger. The flexible metal-clad laminate is characterized by comprising the film and a metal layer disposed thereon.

Claim (Index 5):
The film according to  claim 1 , wherein the crystalline thermoplastic polyimide is produced by a process comprising imidizing a polyamic acid obtained by reacting a diamine component and a dianhydride component,\n wherein the diamine component comprises at least one selected from the group consisting of 1,4-bis(4-aminophenoxy)benzene, 1,3-bis(4-aminophenoxy)benzene, 4,4\u2032-bis(3-aminophenoxy)biphenyl, 4,4\u2032-bis(4-aminophenoxy)biphenyl, 1,4-diaminobenzene, and 3,4\u2032-diaminodiphenyl ether, and the dianhydride component comprises at least one selected from the group consisting of pyromellitic dianhydride, 3,3\u2032,4,4\u2032-biphenyl tetra carboxylic dianhydride, and 3,3\u2032,4,4\u2032-benzophenone tetra carboxylic dianhydride.
