Abstract: An ink composition for photonic sintering and a method or producing the ink composition, the ink composition includes: metal nanoparticles comprising a first metal satisfying interaction formula 1; an organic non-aqueous binder; and a non-aqueous solvent. Interaction formula 1 is A1/A2≤0.2, where A1/A2 is a ratio, in the x-ray photoelectron spectrum on the surface of the first metal, in which first metal 2p3/2 peak area of the oxide of the first metal (A1) is divided by first metal 2p3/2 peak area of the first metal (A2).

Abstract: Metal nanoparticles according to the present invention have at least a bimodal size distribution in which the ratio obtained by dividing the area of a first peak, which has the smallest median size on the basis of the median size of peaks in the size distribution of the metal nanoparticles, by the total area of all peaks constituting the size distribution meets 0.4-0.8, and are capped with a capping layer containing an organic acid.
