Abstract
The present invention provides a method for forming an electrode of a flat panel display device using ink for ink jet printing and an ink jet printer. The ink for ink jet printing is prepared by a method comprising the first step of contacting the vapor of a metal with the vapor of the first solvent, according to the vapor phase-evaporation technique, to thus give a dispersion of metal ultrafine particles; the second step of adding a low molecular weight polar solvent as the second solvent to the dispersion prepared in the first step to thus precipitate the metal ultrafine particles and removing the first solvent; and the third step of adding the third solvent to the precipitates thus prepared to carry out the solvent substitution and to give a dispersion of independently dispersed metal ultrafine particles, and prepared by adding a dispersant in or during the foregoing first and/or third steps, and the ink for ink jet printing consists of a dispersion excellent in ink characteristic properties. In the dispersion, metal ultrafine particles having a particle size of not more than 100 nm are independently and uniformly dispersed. The electrodes of FPD devices are formed using this ink for ink jet printing.
