    摘要： Disclosed is a highly heat-resistant thermosetting polyimide resin composition having long pot life, which enables to obtain a cured product having flexibility and adhesiveness. The thermosetting polyimide resin composition can be obtained through the following steps (1)-(3). Step (1): A step wherein a polyimide (A) is synthesized by a thermal reaction by blending a tetracarboxylic acid component, which is composed of a tetracarboxylic acid dianhydride represented by the formula (1) and one or more compounds selected from tetracarboxylic acids represented by the formula (2) and derivatives of such tetracarboxylic acids, with an aliphatic diamine represented by the formula (3) in such a ratio that the mole number of the tetracarboxylic acid component is higher than the mole number of the aliphatic diamine. Step (2): A step wherein a polyimide (B) is synthesized by a thermal reaction by blending the polyimide (A) obtained in the step (1) with an aromatic diamine represented by the formula (4). Step (3): A step wherein the polyimide (B) obtained in the step (2) is blended and mixed with a bismaleimide compound represented by the formula (5).
