Abstract: Transfer tapes include an optically transparent adhesive layer with a first major surface and a second major surface, with at least one of the major surfaces including a microstructured pattern that is a permanent feature of the adhesive surface. The microstructured surface alters the direction of light. The optically transparent composition may include a low Tg polymeric component with a Tg of less than 20° C., and an acid or base functionality, and a high Tg polymeric component with a Tg of greater than 20° C., and an acid or base functionality, such that the functionality of the low Tg polymeric component and the functionality of the high Tg polymeric component form an acid-base interaction when mixed. The transfer tapes can be adhered to substrates to provide a microstructured surface to the substrate surface.

Abstract: The present invention relates to 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.
Abstract translation: 本发明涉及一种包括光源和光学制品的光学装置。 光学制品包括设置在光导上的光导和粘弹性层。 由光源发出的光线进入光导，并通过全内反射在光导内传输。 粘弹性层管理光，例如可以提取进入光导的光的至少约50％或小于约10％。 光学装置可以用于各种用于符号，标记，显示装置，键盘组件，尾灯组件和照明装置的结构。

Abstract: Variable index light extraction layers that contain a first region with a first material and a second region including a second material are described, where the first region has a lower effective index of refraction than the second region. Optical films and stacks may use the variable index light extraction layers in front lit or back lit display devices and luminaires.
