The present invention relates to a polyimide resin composition including an organic thiol compound and a thermoplastic polyimide resin, a polymeric film containing the polyimide resin, a laminate including the same, and a printed circuit board. By using the polyimide resin composition, it is possible to form an electroless plating film having high adhesive strength even under high-temperature, high-humidity conditions in spite of the fact that the surface roughness of the insulating layer is extremely low. Furthermore, by using the polymeric film and a laminate including the polymeric film and a metal layer, it is possible to obtain a printed circuit board capable of forming high-density circuit and having excellent adhesiveness, and excellent adhesion reliability in a high-temperature, high-humidity environment. |
