A process for forming polymer particles containing metallic flakes, comprising: a) forming a suspension of metallic flakes in a solution of a polymeric binder in a solvent; b) forming droplets of the suspension, c) freezing the droplets to freeze solvent in the droplets to form frozen solvent domains within the polymeric binder, and d) removing the frozen solvent from the polymeric binder thereby forming porous polymer particles containing the metallic flakes encapsulated therein.
