Patent ID: 8841375

Claim:
A method, comprising a) adding, to an aqueous solution of a transition metal salt, a reducing agent and an acrylate or methacrylate monomer, an acrylate or methacrylate oligomer, or a polyacrylate or polymethacrylate, thereby obtaining a colloidal solution comprising nano shaped transition metal particles; either b1) treating the colloidal solution with a peroxide or b2) exposing the colloidal solution to UV- or visible light; c) adding a water soluble amine to the colloidal solution after said b1) treating or said b2) treating is performed; and d) re-dispersing nano shaped transition metal particles together with a dispersing agent in a liquid acrylate or methacrylate monomer, wherein the transition metal of the nano shaped transition metal particles comprises at least one member selected from the group consisting of Zn, Ag, Cu, Au, Ta, Ni, Pd, Pt, Co, Rh, Ir, Fe, Ru, and Ti.
