Abstract:
The invention relates to a method for preparing an aqueous-based dispersion of metal nanoparticles comprising: (a) providing an aqueous suspension of a metal salt; (b) pre-reducing the metal salt suspension by a water soluble polymer capable of metal reduction to form a metal nuclei; and (c) adding a chemical reducer to form metal nanoparticles in dispersion. The invention further relates to aqueous-based dispersions of metal nanoparticles, and to compositions such as ink comprising such dispersions.
