ABSTRACT:
Plastic surfaces are activated for the reception of adherent metal coatings by depositing noble metal nuclei thereon, the noble metal nuclei being deposited by a multistep process including the steps of mechanically roughening the surface, treating the roughened surface with a complex-former solution, thereafter treating the surface with a solution of a noble metal complex salt so as to exchange the noble metal complex for the complex deposited by the initial complex-former solution, and converting the noble metal complex to form metal nuclei.
