<p>Resin compositions comprising polyimides composed of repeating units represented by general formula (1), (wherein Ar0 is a C¿6?-C15 aromatic hydrocarbon group; and R?1¿ is at least one member selected from the group consisting of divalent residues obtained by removing two amino groups from a C¿2?-C30 aliphatic diamine and those obtained by removing two amino groups from a C4-C30 alicyclic diamine), and polyarylates or polyester carbonates. The compositions are excellent in heat resistance, dimensional stability and transparency, among which ones exhibiting particularly excellent transparency are suitable for bases of flexible printed boards or other moldings.</p> |
