Abstract:
The present invention relates to a process for producing a colloidal metal solution, which comprises a first step of forming colloidal metal particles with a sulfur compound of low molecular weight on the particle surfaces in a solution, a second step of adjusting the solution to a pH of not more than 5, thereby aggregating the colloidal metal particles and recovering the colloidal metal particles by filtration, and a third step of dispersing the recovered colloidal metal particles into a dispersion medium at a pH of 8-14.
