Abstract: Provided are methods of making a transfer tape in which first and second release coatings are disposed onto respective first and second major surfaces of a backing to provide a release liner, the first release coating comprising wax particles at least partially embedded in a polymeric layer. An adhesive precursor is coated onto the first release coating and the adhesive precursor and the release liner collectively irradiated with an electron beam to convert the adhesive precursor into an adhesive layer. Advantageously, the provided transfer tape can be wound into a roll and stored for long periods without exhibiting degradation of release properties attributable to either blocking or electron beam degradation of the liner release coating.
