    摘要： Disclosed is ink for ink jet printing, which comprises: metal nanoparticles comprising a surfactant attached to surfaces thereof; and a first solvent, wherein the metal nanoparticles are present in an amount of 50˜70 parts by weight based on 100 parts by weight of the ink, and the surfactant is present in an amount of 0.5˜5 parts by weight based on 100 parts by weight of the metal nanoparticles. Metal nanoparticles used in the ink and a method for preparing the metal nanoparticles are also disclosed. The method for preparing metal nanoparticles for use in ink for ink jet printing comprises a step of washing surplus surfactant with at least one solvent. By doing so, the surplus surfactant remaining on the surfaces of the metal nanoparticles can be minimized, resulting in a drop in viscosity of ink comprising the metal nanoparticles. Therefore, even if the ink has a metal nanoparticle content of 50 wt % or more, the ink can satisfy a viscosity condition required for ink jet printing, and thus can form an electrode pattern with high conductivity.

    摘要： Disclosed is a dispersion adjuvant for metal nanoparticles, which comprises an amide derivative. Metal nanoink comprising the dispersion adjuvant is also disclosed. The dispersion adjuvant helps metal nanoparticles to be dispersed in a solvent in the presence of a dispersant, inhibits metal particles from agglomerating among themselves, and increases the content of metal nanoparticles in a solvent. Additionally, interconnection lines formed by using the nanoink have an increased content of metal per unit area, and thus provide improved conductivity.
