Viscosity adjustment method and particle dispersion liquid production method

Abstract

A method for adjusting a viscosity, the method including adjusting a relative relationship between a viscosity of a particle dispersion containing particles and a liquid medium, and a viscosity of the liquid medium, based on a distance of an HSP value of the particles with respect to an HSP value of the liquid medium. A method for producing a particle dispersion, the method including: a step of selecting particles and a liquid medium based on a distance of an HSP value of the particles with respect to an HSP value of the liquid medium; and a step of mixing the particles and the liquid medium with each other.
