    Abstract: The release composition includes a siloxane polymer having a weight average molecular weight of at least 1000 grams per mole, a first crosslinker and a second crosslinker, each crosslinker independently a compound represented by formula Si(OR5)4 or R1Si(OR5)3, or a compound having at least two groups represented by formula —Si(R4)x(OR5)3-x, and a photoacid generator. The siloxane polymer includes repeating divalent units represented by formula and at least two functional groups selected from silanol, alkoxy silane, —Si(OR2)y(R″)3-y, and a combination thereof. In these formulas, each R is independently alkyl, each R2 is independently hydrogen or alkyl, each R″ is independently alkyl or aryl, y is 1, 2, or 3, each R4 is independently alkyl or aryl, each R1 and R5 is independently alkyl; and x is 0 or 1. An article including a cured reaction product of the release composition and a method of making the article are also described.

    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: R1 represents a monovalent, divalent, or trivalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. Rf represents a perfluorinated group having from 3 to 5 carbon atoms. X1 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.

    Abstract: 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—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.

    Abstract: Disclosed herein is an optical device having a light source, a viscoelastic lightguide and a retroreflective film suitable for retroreflecting light. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The optical device may have a “front lit” configuration such that light being transported within the lightguide is extracted and retroreflected by the film toward a viewer. The optical device may have a “back lit” configuration such that light being transported within the lightguide is extracted and transmitted through the film toward a viewer. The retroreflective film may comprise beaded retroreflective sheeting such as that used in traffic signs and markings.
