POLYIMIDE RESIN COMPOSITION AND LAMINATE INCLUDING SAME

摘要

The present invention addresses the problem of providing a resin composition including a polyimide that is soluble in a solvent and from which a resulting film will be highly viscoelastic and flexible at high temperatures. In order to resolve this problem, a polyimide resin composition includes a polyimide including polycondensate units of tetracarboxylic dianhydride and diamine, wherein either the tetracarboxylic dianhydride includes a dianhydride (a1) represented by general formula (1) or the diamine includes an aromatic diamine (ß1) represented by general formula (2) and the diamine includes an aliphatic diamine (ß2) represented by general formula (3) or (4), the sum amount of the dianhydride (a1) and aromatic diamine (ß1) contained therein being 5-49 mol% with respect to the sum of the tetracarboxylic dianhydride and the diamine, and the amine equivalent thereof being 4,000-20,000.
