    摘要: The present invention provides a dispersion usable for forming an electroconductive layer having an extremely fine pattern and a high thickness/minimum width ratio in the cross-section, and which has a high fluidity enabling application of inkjet to draw a fine pattern at high accuracy and contains only metal nanoparticles as a conductive medium. According to the present invention, a metal nanoparticle dispersion suitable to multiple layered coating by jetting in the form of fine droplets is prepared by dispersing metal nanoparticles having an average particle size of 1 to 100 nm in a dispersion solvent having a boiling point of 80° C. or higher in such a manner that the volume percentage of the dispersion solvent is selected in the range of 55 to 80% by volume and the fluid viscosity (20° C.) of the dispersion is chosen in the range of 2 mPa·s to 30 mPa·s, and then when the dispersion is discharged in the form of fine droplets by inkjet method or the like, the dispersion is concentrated by evaporation of the dispersion solvent in the droplets in the course of flight, coming to be a viscous dispersion which can be applicable to multi-layered coating.

    摘要: An electrostatic attraction fluid jet device of the present invention is so arranged that a nozzle (4) is formed so as to correspond to a meniscus equivalent to a tip portion in the form of a taylor cone formed in a process of an electrostatic attraction of ink (2) as a conventional fluid. A diameter of an ink-ejecting hole (4b) of the nozzle (4) is set to be substantially the same as a diameter of the tip portion, which is about to be ejected, of the meniscus (14) of ink. Moreover, the diameter of the ink-ejecting hole (4b) of the nozzle (4) is set to be equal to or less than a droplet diameter of the ink (2) which has just been ejected. Therefore, it is possible to provide an electrostatic attraction fluid jet device which can realize a recording device which has high resolution, is safe and is highly versatile.
