Polyimide silicone resin derived from diamine including diaminopolysiloxane and acid dianhydride, for, e.g., prevention of corrosion of liquid-crystal display panel electrodes, has specified amount of siloxane residual group

摘要

A polyimide silicone resin derived from a diamine including a diaminopolysiloxane and an acid dianhydride, consists of >=50 wt.% siloxane residual group and has an elongation at rapture of >=400% and a modulus of elasticity of =500 N/mm2>. Independent claims are also included for: (A) a polyimide silicone resin solution composition including the inventive polyimide silicone resin and an organic solvent for dissolving the polyimide silicone resin; and (B) a polyimide silicone resin film including the inventive polyimide silicone resin formed on a substrate, i.e., an electrode for electronic component parts or semiconductor devices.
