(57) [Problem] To provide an active energy ray-curable polyimide resin composition which has heat resistance, can be patterned with a dilute aqueous alkali solution, and is soluble in an organic solvent. SOLUTION: The concentration of the polymerizable polyimide resin (I) having an isocyanurate ring, a cyclic aliphatic structure, an imide ring and a (meth) acryloyl group and capable of being patterned with a dilute aqueous alkali solution, preferably the concentration of the isocyanurate ring Is 0.4 １．２1.2 mmol / g, the concentration of (meth) acryloyl group is 0.3-4 mmol / g, and the acid value is 20-250. And the number average molecular weight is 1,000 to 20,000, and An active energy ray-curing type containing a polyimide resin having a weight average molecular weight of 1,500 to 30,000 and, if necessary, further containing an organic solvent (II), an epoxy compound (III) and a photoinitiator (IV). Polyimide resin composition. |
