Abstract: A polyimide-based polycondensate which may be used as an insulation film by coating a copper foil with the polycondensate and by heating the coated copper foil, which insulation film does not warp the foil, as well as a production process thereof, is disclosed. The polycondensate according to the invention is a solvent-soluble polycondensate containing a benzoxazole component having a carboxylic group and an imide component having a phenolic hydroxyl group, which is obtained by dehydration-condensing one or more tetracarboxylic dianhydrides with one or more aromatic diamines having an amino group and a phenolic hydroxyl group, the amino group and the phenolic hydroxyl group being located at ortho positions with respect to each other, by heating the one or more tetracarboxylic dianhydrides and the one or more aromatic diamines at 150 DEG C to 220 DEG C in the presence of an acid catalyst.

Abstract: A composition for electro-depositing polyimide membranes which can be patterned by photolithography, which are excellent in heat resistance, insulation performance and in chemical resistance. The composition for electrodeposition of polyimides according to the present invention comprises a composition for electrodeposition of polyimides comprising a photoacid generator, a positive-type photosensitive polyimide having oxycarbonyl groups in side chains, a polar solvent which dissolves said polyimide, water, a dispersing agent, and an alkaline neutralizer.
