    Abstract: Release layers that can be included in various adhesive tape products and release liners for adhesive layers are provided. The release layer is a cured reaction product of a curable release composition that contains i) a siloxane polymer having at least two hydrolyzable groups and having a weight average molecular weight of at least 1000 Daltons, ii) a crosslinker, iii) a silane additive, iv) a photoacid generator, and v) an optional silicate resin. The crosslinker is a compound of formula Si(OR 5 ) 4 or is a compound having at least two silyl groups of formula -Si(R 4 )x(OR 5 ) 3 -x where R 4 is alkyl or aryl, R 5 is alkyl, and the variable x is an integer equal to 0 or 1. The silane additive is a compound having two silyl groups of formula -Si(R 6 ) 2 (OR 7 ) or a single silyl group of formula -Si(R 10 )(OR 9 ) 2 where R 6 is alkyl or aryl, R 7 is alkyl, R 9 is alkyl, and R 10 is alkyl or aryl.

    Abstract: 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: R 1 represents a monovalent, divalent, or trivalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. R f represents a perfluorinated group having from 3 to 5 carbon atoms. X 1 represents -NH- 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.
