Abstract
The present invention relates to [1] a process for producing a metal fine particle dispersion containing metal fine particles (a) dispersed with a polymer B, including the step 1 of mixing a metal oxide A, the polymer B and a compound C with each other, in which the polymer B contains a hydrophilic group; the compound C is a dihydric alcohol represented by the general formula (1); and the metal fine particles (a) have a cumulant average particle size of not more than 50 nm, and [2] an ink containing the metal line particle dispersion obtained by the production process described in the above [1].
