    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.

    Abstract: Pressure sensitive adhesive compositions are described comprising at least one low Tg ethylenically unsaturated monomer, and at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The low Tg ethylenically unsaturated monomer typically has a Tg no greater than 10° C. In some embodiments, the composition comprises at least 50, 55, 60, 65, or 70 wt-% of low Tg ethylenically unsaturated monomer. The low Tg ethylenically unsaturated monomer is typically an alkyl (meth)acrylate comprising 4 to 20 carbon atoms. In another embodiment, an adhesive composition is described comprising a syrup. The syrup comprising i) a free-radically polymerizable solvent monomer; ii) a solute (meth)acrylic polymer comprising polymerized units derived from one or more alkyl (meth)acrylate monomers, and iii) at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The free-radically polymerizable solvent monomer, polymerized units of the solute (meth)acrylic polymer, or a combination thereof comprise a low Tg ethylenically unsaturated monomer. Also described are pressure sensitive adhesive articles and method of preparing adhesive articles.
