摘要： A polyamic acid resin composition includes (a) a polyamic acid having structures represented by general formula (1) in an amount of at least 80% of all the repeating units and (b) a solvent. In formula (1), A is a polyamic acid block represented by general formula (2); B is a polyamic acid block represented by general formula (3); and k is a positive integer. In formula (2), Ws are divalent organic groups having two or more carbon atoms, mainly composed of divalent organic groups represented by general formula (4); Xs are tetravalent organic groups having two or more carbon atoms. In formula (3), Ys are divalent organic groups having two or more carbon atoms, exclusive of the groups represented by formula (4); Zs are tetravalent organic groups each having two or more carbon atoms, and are mainly composed of tetravalent organic groups represented by general formula (5) or (6).
