An object of the present invention is to provide a method of forming an electrode of a flat panel display (FPD) using an inkjet ink and using an inkjet printer.n n n In order to solve the above problems, a first step of obtaining a metal ultrafine particle dispersion by contacting the metal vapor and the first solvent vapor by the gas evaporation method, and by adding a second solvent of a low molecular weight polar solvent to the dispersion liquid to form a metal ultrafine particle And a third step of precipitating, extracting and removing the first solvent, and a third step of adding a third solvent to the obtained precipitate and solvent replacement, thereby obtaining a metal ultrafine particle dispersion, and the first step and / or the third step. The dispersing agent is added at to obtain an ink jet ink composed of a dispersion having excellent ink characteristics. Ultrafine metal particles having a particle diameter of 100 nm or less are uniformly dispersed in an independent state. Using this inkjet ink, electrode formation of FPD is performed. |
