Polyimide-Silikonharz, dieses Harz enthaltende Lösung und Polyimide-Silikonharz-Film

摘要

A polyimide silicone resin which is obtained from a diamine containing an acid dianhydride and a diaminopolysiloxane, contains 50% by weight or more of a siloxane residual group and has an elongation at rapture of 400% or higher and a modulus of elasticity of 500 N/mm<2> or lower. Also disclosed are a polyimide silicone resin solution composition comprising this polyimide silicone resin and a ketone solvent having a boiling point of 130 DEG C or below, and a polyimide silicone resin film comprising this polyimide silicone resin and formed on a substrate. The polyimide silicone resin can form films at relatively low temperature, has superior adhesiveness to substrates and durability under conditions of high humidity and also has low stress and high elongation.
