Abstract
A novel modified polyimide resin having a polybutadiene sheleton and obtainable by reacting the following three (3) kinds of compounds, i.e., a bifunctional hydroxyl-terminal polybutadiene having a number average molecular weight of 800 to 5,000, a tetrabasic acid dianhydride, and a diisocyanate compound, imparts reduced shrinkage upon setting to a thermosetting resin composition comprising the same and also imparts heat resistance and pliability and the like to a hardened mass or article of such thermosetting resin composition. Therefore, such thermosetting resin composition is an excellent resin composition capable of fully satisfying the requirements with regard to the characteristics of an overcoat agent for a wiring circuit which should be pliable, such as a flexible wiring circuit substrate, a film carrier and the like.
