Method for Producing Layered Materials Using Long-lived Photo-induced Active Centers

The invention relates to a method for applying a photo-activated layered polymer coating to a substrate material in which one or more layers do not contain photoinitiator, or are not exposed to initiating light, but cure due to migration of cationic active centers. At least two separate monomer layers are applied to the substrate material. At least one of the monomer layers includes a photoinitiator capable of producing cationic active centers. The at least one layer including the photoinitiator is exposed to a source of UV radiation at a desired wavelength forming cationic active centers. The at least two separate monomer layers react in a polymerization reaction forming a cured layered material. The cationic active centers of the exposed monomer layer migrate to the unexposed layer such that both layers cure via the polymerization reaction.
