<p>A method by which an electrode for flat panel displays (FPDs) is formed from an ink-jet ink with an ink-jet printer. The ink-jet ink, which comprises a dispersion having excellent ink properties, is obtained by a process which comprises: a first step in which a metal vapor is contacted with a first-solvent vapor by the gas vaporization method to obtain a dispersion of ultrafine metal particles; a second step in which a second solvent which is a low-molecular polar solvent is added to the dispersion to settle the ultrafine metal particles and the first solvent is removed by extraction; and a third step in which a third solvent is added to the resultant sediment to conduct solvent replacement and obtain a dispersion of ultrafine metal particles, a dispersant being added in the first step and/or the third step. In the ink, the ultrafine metal particles, which have a particle diameter of 100 nm or smaller, are evenly dispersed independently. Using the ink-jet ink, an electrode for an FPD is formed.</p> |
