摘要： The present invention aims to provide a carboxyl group-containing polyimide, and prepolymer thereof which give a cured product highly satisfying thermosetting property, PCT resistance, solvent resistance and peel strength at the same time. The present invention relates to a terminal acid anhydride group-containing imide prepolymer which is characterized by being produced by reacting an acid anhydride group in a tetracarboxylic acid dianhydride with an isocyanate group in a diisocyanate compound, and a carboxyl group-containing polyimide which is characterized in having such a structure where the chain of said terminal acid anhydride group-containing imide prepolymer is extended via a polyol compound. The present invention also relates to a thermosetting resin composition and a flexible metal-clad laminate which utilize such carboxyl group-containing polyimide.
