In a process for the production of a strongly adherent coating on an inorganic or organic substrate, wherein a), a low-temperature plasma treatment, a corona discharge treatment or a flame treatment is carried out on the inorganic or organic substrate, b) one or more photoinitiators or mixtures of photoinitiators with monomers or/and oligomers, containing at least one ethylenically unsaturated group, or solutions, suspensions or emulsions of the afore-mentioned substances, are applied to the inorganic or organic substrate, and optionally, c) using suitable methods those afore-mentioned substances are dried and/or are irradiated with electromagnetic waves, it proves advantageous to use compounds of formula (I), (II), (III) and/or (IV), IN-L-RG (I), >IN-L-RG
