Abstract
A method for coating aluminum particles with a polymer film, includes the following steps: (A) providing an aqueous dispersion of metal aluminum particles using surfactants, the aluminum particles being contacted with S.sub.2O.sub.8.sup.2- persulphate anions; then (B) providing an emulsion type polymerization in the aqueous dispersion thus obtained, by introducing into the dispersion monomers whereof the free radical polymerization is initiated by the persulphate anions, or by introducing into the emulsion monomers and an initiator for polymerizing the monomers, whereby a polymer film is formed on the surface of the aluminum particles. The invention also concerns pigment compositions based on aluminum particles coated with polymer films, obtainable by the method, as well as the use of the compositions for formulation of paints having a metallized appearance.
