A process for modifying the surface of a polymeric substrate. The process includes digitally applying a photoreactive material comprising at least one photochemical electron donor to a region of a polymeric substrate and exposing at least a portion of that region to actinic radiation. The modified surface of the polymeric substrate may be bonded to one or more additional substrates, or may be coated with a fluid.
L'invention concerne un procédé modifiant la surface d'un substrat polymère. Ce procédé consiste à appliquer numériquement un matériel photoréactif comportant au moins un donneur photochimique d'électron à une région d'un substrat polymère et à exposer au moins une partie de cette région au rayonnement actinique. La surface modifiée du substrat polymère peut être collée sur un ou plusieurs substrats additionnels, ou peut être enduite d'un fluide.
