The second silicone release layer comprises a partially cured hydrosilation-crosslinkable silicone mixture comprises a first silicone polymer having at least three Si—H groups and second silicone polymer have at least two vinyl, and has an extractables content of 5 to 25 weight percent. Second, an adhesive layer is disposed onto the first silicone release layer. Third, the adhesive layer is exposed to E-beam radiation within a process chamber thereby providing a crosslinked adhesive layer. The second silicone release layer is exposed to oxygen during crosslinking of the adhesive layer. Adhesive articles made according to the method also disclosed.
