Abstract: The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film, having a first pressure sensitive adhesive layer and at least an opposing layer, wherein the first pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition with a (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising: (a) a first monomer which is an alkyl (meth)acrylate ester of a primary alcohol R1—OH, the alkyl (meth)acrylate ester being of Formula (I) CH2═C(R2)—(CO)—OR1   (I) wherein R1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R1—OH has an iso index equal to at least 2 but no greater than 4; R2 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group; wherein the at least one opposing layer comprises at least one filler material. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.

Abstract: Optical devices include a light source and an optical article, where the optical article is an acid-free, non-yellowing pressure sensitive adhesive light guide. The light source is optically coupled to the light guide such that light emitted by the light source enters the light guide and is transported within the light guide by total internal reflection. The light guide includes a plurality of features oriented to extract light being transported within the light guide.
