This invention concerns a process for modifying a polymeric substrate by contacting the surface with a photoreactive solution of an inorganic photochemical electron donor while irradiating the surface with actinic radiation. Patterns of modified and unmodified surfaces can be produced. Polymeric substrates with modified surfaces may be effectively bonded to polymer films to form composite articles. The process has particular applicability to the surface modification of fluorinated polymers.
