POLYIMIDE RESIN, POLYIMIDE FILM, AND POLYIMIDE LAMINATE

摘要

Disclosed is a polyimide resin composed of a repeating unit represented by the formula (1) below, or alternatively a repeating unit represented by the formula (1) below and at least one repeating unit represented by the formula (2) below (wherein X is as defined in the description). [Chemical formula 1] [Chemical formula 2] The polyimide resin is good in thermoplasticity, solubility in solvents and heat resistance, while exhibiting low water absorption and excellent adhesiveness. This polyimide resin is useful as a material for the adhesive layer in a metal-clad laminate which includes an insulating base, a metal layer and an adhesive layer arranged between the insulating base and the metal layer.
