Abstract

The invention relates to a method of printing onto the surface of a substrate, which method comprises a. coating a donor surface with a monolayer of individual particles, b. treating the surface of the substrate to render the affinity of the particles to at least selected regions of the surface of the substrate greater than the affinity of the particles to the donor surface, and c. contacting the surface of the substrate with the donor surface to cause particles to transfer from the donor surface only to the treated selected regions of the surface of the substrate, thereby exposing regions of the donor surface from which particles are transferred to the corresponding regions on the substrate, and characterised in that at least 50 wt. % of the particles are flaky metal pigments comprising a flaky metallic substrate and a surface modification layer of the metallic substrate, wherein the surface modification layer has been made by a treatment of the metallic substrate surface by at least one of the modification substances from the group consisting of phosphate ester, phosphonic esters, phosphonic acids, phosphinate esters, organofunctional silanes, organofunctional titanates, organofunctional zirconates, organofunctional aluminates and mixtures thereof.
