POLYIMIDE RESIN

摘要

a polyimide resin which is soluble in an organic solvent and has a low water-absorption coefficient, excellent thermoplasticity, high heat resistance and excellent adhesion properties; a process for producing the polyimide resin; an adhesive agent comprising the polyimide resin; and a metal-clad laminate comprising a film and an adhesive layer comprising the polyimide resin. The polyimide resin has a repeating unit represented by the formula (1) and a repeating unit represented by the formula (2) and contains a group represented by the formula (3) in an amount of 50 mol% or more relative to the total amount of a group X.
