Abstract

A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, especially release-coated substrates, in which the pressure-sensitive adhesive system is applied in one or more layers to a rotating roller by means of an adhesive applicator, the pressure-sensitive adhesive system on the roller is crosslinked in an irradiating means by means of high-energy radiation, and the roller is contacted with the substrate, so that the pressure-sensitive adhesive system is transferred from the roller to the substrate.
