  • Publication number: 20090130468
    Abstract: The present invention provides a polyamic acid composition obtained by addition polymerization of an aromatic diamine and an aromatic dianhydride in a solvent, and then the imidazole or derivatives thereof (or triazole or derivatives thereof), and epoxy resin are added thereto. When the polyamic acid composition, which contains imidazole or derivatives thereof (or triazole or derivatives thereof), and epoxy resin, is cast onto a clean metal foil and then heated and imidized to form a polyimide insulating layer, the imidazole or derivatives (or triazole or derivatives thereof) will react with the epoxy resin to form a polymer during imidation.
