Patent ID: 11939482

Abstract:
A conductive ink composition for screen printing contains a conductive metal particle (A) having an oleic acid surfactant, a non-chlorine-based resin composition (B), and an organic solvent (C), wherein the conductive metal particle (A) is contained in an amount of 45 to 70% by weight with respect to the total ink composition, the non-chlorine-based resin composition (B) has a number average molecular weight of 50,000 or more and is contained in an amount of 5 to 15% by weight with respect to the total ink composition, the organic solvent (C) has a flash point of 75 to 110° C. and is contained in an amount of 25 to 50% by weight with respect to the total ink composition, and the ink composition has an ink viscosity of 10 to 25 Pa·s (23° C.) at a shear rate of 100 s−1.
