Abstract
A description is given of a method of crosslinking radiation-crosslinkable pressure-sensitive adhesive films by controlled-dose exposure to actinic radiation, which involves exposing the film surface to a regular or irregular radiation pattern made up of regions of different intensity. The method permits a more precise adjustment of the adhesion—in particular, the adhesion of flexible films on a substrate.
