摘要： The invention relates to a process for the production of strongly adherent coatings on an inorganic or organic substrate that comprises, in a first step a) subjecting the inorganic or organic substrate to the action of a low-temperature plasma discharge, a corona discharge, high-energy UV radiation or electron radiation, then discontinuing the radiation or discharge; in a further step b) under vacuum or at normal pressure, applying one or more photoinitiators containing at least one ethylenically unsaturated group to the inorganic or organic substrate, and allowing reaction with the free-radical sites formed there; and c1) coating the substrate so precoated with photoinitiator with a composition comprising at least one ethylenically unsaturated monomer or oligomer, and curing the coating by means of UV/VIS radiation or c2) depositing a metal, semi-metal oxide or metal oxide from the gaseous phase, in the presence of UV light, on the substrate so precoated with photoinitiator. The invention relates also to the use of photoinitiators having at least one ethylenically unsaturated group in the production of such layers and to the strongly adherent coatings themselves.
