Patent ID: 10066058

Abstract:
A polyimide resin contains repeating structural units represented by formulas (1) and (2), wherein the content of the repeating structural unit represented by formula (2) relative to the total of the repeating structural unit represented by formula (1) and the repeating structural unit represented by formula (2) falls within a specific range and the content of the divalent group represented by the following structural formula (B1) falls within a specific range: X1 represents a tetravalent group containing an alicyclic hydrocarbon structure and having a carbon number of from 4 to 22. X2 represents a tetravalent group containing an aromatic ring and having a carbon number of from 6 to 22. R1 and R2 each independently represent a divalent organic group, and the content of the divalent group represented by the following structural formula (B1) relative to the total of R1 and R2 is from 80 to 100 mol %:
