    摘要： The disclosure generally relates to optical elements such as switchable privacy filters useful for displaying information in at least two modes. In the first mode, the viewing angle can be limited to restrict viewing to near-normal orientations. In the second mode, the viewing angle can be increased so that the information can be viewed at larger oblique angles. The disclosure also relates to switchable privacy displays that include the switchable privacy filters.

    摘要： Disclosed herein is an optical device including a light source and an optical article. The optical article includes a lightguide and a viscoelastic layer disposed on the lightguide. Light emitted by the light source enters the lightguide and is transported within the lightguide by total internal reflection. The viscoelastic layer manages light, for example, at least about 50%, or less than about 10%, of light that enters the lightguide may be extracted. The optical device can be used in a variety of constructions for signs, markings, display devices, keypad assemblies, tail light assemblies and illumination devices.

    摘要： 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.

    摘要： An adhesive article is disclosed. The adhesive article includes a reinforced tape and a pressure sensitive layer disposed on the reinforced tape. The pressure sensitive layer includes an adhesive blend of 25 to 75 parts by weight of a first hydrophilic pressure sensitive adhesive having a first polyacrylate, 60 to 24 parts by weight of a non-hydrophobic pressure sensitive adhesive having a second polyacrylate, and 15 to 1 parts by weight of a tackifying agent. The adhesive blend includes a cross linking agent. The non-hydrophobic pressure sensitive adhesive is miscible in the hydrophilic pressure sensitive adhesive and the second polyacrylate is different from the first polyacrylate. Methods of making and using adhesive articles are also disclosed.

    摘要： Light-activated antimicrobial devices and articles are disclosed. The devices include a light source and a light-activated antimicrobial article comprising a photosensitizer and a viscoelastic material such as a pressure sensitive adhesive adapted to receive light from the light source. The viscoelastic material may be adapted to transport light by total internal reflection. The photosensitizer may comprise a dye, a metal oxide or a composition that comprises anions that oxidize or react to form a gas. Upon activation of the light source, the photosensitizer absorbs light from the light source such that antimicrobial activity is exhibited. The photosensitizer may be included in the light-activated antimicrobial article or it may be provided as a topical composition that is separate from the article. The light-activated antimicrobial articles and devices may have constructions similar to those of wound dressings.
