Abstract (en)
A surface layer of a polymeric material, for instance an epoxy or other polymeric printing substrate, is prepared to receive a metal or other adherent coating by penetrating the surface layer with a first reactant and then with a second reactant that reacts in the surface layer to form pits that extend from the surface into the surface layer. The first reactant may comprise a pyrrole and the second reactant may comprise chromic acid.
