A method of making an adhesive article comprises three steps. First, a backing is provided having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer further comprises a compound represented by the formula: Rrepresents a divalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. Rrepresents a monovalent or divalent poly(dimethylsiloxane) moiety. X represents &#x2014;NH&#x2014; or a covalent bond. Rrepresents a perfluorinated group having from 3 to 5 carbon atoms. y is 1 or 2. 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 containing oxygen to provide a crosslinked adhesive layer. An adhesive article made by the method and the compound are also disclosed.

A method of making an adhesive article comprises three steps. First, a backing is provided having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer further comprises organic solvent and a compound represented by the formula: Rrepresents a monovalent, divalent, or trivalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. Rrepresents a perfluorinated group having from 3 to 5 carbon atoms. Xrepresents &#x2014;NH&#x2014; or a covalent bond. 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 containing oxygen to provide a crosslinked adhesive layer. An adhesive article made by the method and the compound are also disclosed. 

A method of making an adhesive article comprises three steps. First, the method includes providing a liner having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer comprises a partially cured hydrosilation-crosslinkable silicone mixture comprises a first silicone polymer having at least three Si&#x2014;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.
