Abstract:
A method of forming a pattern on a base material selected from glass and ceramic by an ink jet method, comprising the steps of:preparing an ink composition by uniformly dispersing a pigment in a solvent with a dispersant for enhancing an affinity between the solvent and the pigment; ejecting the ink composition onto a surface of a base material through a nozzle by the ink jet method to form a droplet of the ink composition on the surface of the base material, wherein the droplet is formed such that the ratio of a volume of the droplet to a surface area of the droplet, except an area contacting the base material, is substantially maximized; evaporating the solvent from the droplet while keeping the ratio substantially at the maximum; and adhering the pigment onto the base material to form a pattern.
