摘要： A polyimide film formed by using a symmetrical aromatic meta-substituted primary diamine and a symmetrical aromatic para-substituted primary diamine as raw materials in a specific proportion has excellent heat resistance, electrical properties, flexibility and the like. Such a polyimide film can be bonded to a metal foil not by using any adhesive, but by coating the metal foil with a polyamic acid constituting a precursor of the polyimide and further reacting the polyamic acid to convert it to the polyimide. In this manner, there can be obtained a flexible laminate for printed-circuit board comprising a polyimide film bonded to a metal foil with good adhesion and exhibiting excellent properties as described above.
