Abstract
A pressure sensitive tape comprising an electron beam radiation crosslinkable pressure sensitive adhesive on a radiation-degradable backing, the adhesive having been crosslinked by exposure to electron beam radiation in a fashion such that the dosage reduction through the adhesive layer is no greater than about 40%; the average dosage which is received by the backing is less than about 80% of that received by the adhesive, and a sufficient dose of beam energy has been provided to produce a gel content in the adhesive of at least about 20% by weight of the elastomer.
