Abstract
NOVELTY - Site selective coupling of multi-atom polar compound (I) to surface of a polymer substrate where regions of the surface are treated with electromagnetic radiation. Components in the base material of the polymer are converted to reactive centers and brought into contact with a liquid solution of the polar compound (I) to couple (I) to the reactive centers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for the selective deposition of a metal layer onto the surface of a polymer substrate comprising: (A) irradiating the areas of the surface to be coated with electromagnetic radiation to produce reactive centers; (B) fixing the reactive functional groups on the surface with a noble metal compound by contact with a solution of one or more noble metal compounds (II); (C) depositing the metal layer in an electroless plating bath. USE - The process is useful for the selective deposition of metal layers or polar compounds onto the surface of polymeric substrate. ADVANTAGE - The process allows the site selective or partial deposition of coatings.
