摘要：A method for coating aluminum particles with a polymer film, includes thefollowing steps: (A) providing an aqueous dispersion of metal aluminum particles usingsurfactants, the aluminum particles being contacted with SOpersulphate anions; then (B)providing an emulsion type polymerization in the aqueous dispersion thus obtained, byintroducing into the dispersion monomers whereof the free radical polymerization isinitiated by the persulphate anions, or by introducing into the emulsion monomers and aninitiator for polymerizing the monomers, whereby a polymer film is formed on thesurface of the aluminum particles. The invention also concerns pigment compositionsbased on aluminum particles coated with polymer films, obtainable by the method, aswell as the use of the compositions for formulation of paints having a metallizedappearance.
