Abstract: A multilayer optical adhesive including a first viscoelastic or elastomeric adhesive layer and a second viscoelastic or elastomeric adhesive layer. A crosslinked or soluble resin layer may be disposed between the first viscoelastic or elastomeric adhesive layer and the second viscoelastic or elastomeric adhesive layer or the first viscoelastic or elastomeric adhesive layer may be immediately adjacent to the second viscoelastic or elastomeric adhesive layer. An interface between immediately adjacent layers is structured and there is a difference in refractive indices across the interface.

Abstract: Articles and methods of making and using the articles are provided. The articles include inorganic agglomerates having an average dimension in a range from about 50 microns to about 2 mm. The porous agglomerates each include a network of carbon or silica, and metal oxide particles embedded in the network. Some agglomerates are capable of lowering a resonant frequency of an acoustic device when the resonant frequency is in a range from about 50 Hz to about 1500 Hz.

Abstract: A transparent electrode is described and includes metallic nanowires and a polymeric overcoat layer for protecting the nanowires from corrosion and abrasion. The polymeric overcoat layer includes nanoparticles, particularly antimony tin oxide, zinc oxide and/or indium tin oxide, and has a sheet resistance of greater than about 107 ohm/sq. The transparent electrode can be used in electronic displays such as polymer-dispersed liquid crystal, liquid crystal, electrophoretic, electrochromic, thermochromic, electroluminescent and plasma displays.

Abstract: Optical stacks including a grating structure that generates diffraction in two in-plane dimensions. The optical stacks may include two gratings, which may be one-directional or two-directional, or may include a single two-directional grating. The optical stacks include particles selected to give controlled diffusion of light. The optical stacks are suitable for reducing sparkle in displays.

Abstract: A method of forming an image having multiple phases is disclosed herein. The method includes forming exposed and unexposed areas, the exposed areas comprising a first polymer network exhibiting first and second phases that are chemically connected and have different refractive indices, the first phase being continuous, and the second phase comprising a plurality of structures dispersed within the first phase, and the unexposed areas comprising a second polymer network comprising third and fourth phases that are chemically connected and have different refractive indices, the third phase being continuous, and the fourth phase comprising a plurality of structures dispersed within the third phase. The first and second polymer networks are chemically connected, and morphology formed by the first and second phases is different than that formed by the third and fourth phases.
