  • Patent number: 11415731
    Abstract: A retroreflective article including a reflective-particle-containing binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a primary reflective layer that covers a portion of the embedded surface area of the transparent microsphere, and a secondary reflective layer provided by portions of the reflective-particle-containing binder layer that are adjacent to portions of the embedded surface area of the transparent microsphere that are not covered by the primary reflective layer.
    Type: Grant

  • Publication number: 20220206195
    Abstract: A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a first layer that is disposed between the transparent microsphere and the binder layer and a second layer that is disposed between the transparent microsphere and the binder layer. At least one of the first layer and the second layer is a reflective layer; and, the first reflective layer and the second reflective layer differ in reflectivity. For at least some of the retroreflective elements, at least a portion of the second reflective layer is positioned in-parallel to the first reflective layer.

  • Publication number: 20120097854
    Abstract: An infrared retroreflecting device used for a high-aspect-ratio optical touch panel, comprising an infrared retroreflecting stripe having a front surface, a back side and an elongated axis; the stripe being formed of a cube-corner retroreflecting structure having a primary groove and at least two secondary grooves; the primary groove being perpendicular to the elongated axis; and the stripe reflecting infrared emitted toward the front surface when an infrared incident angle is ranged from about 0° to about 61°. A method of manufacturing an infrared retroreflecting device used for a high-aspect-ratio optical touch panel, comprising forming a cube-corner retroreflecting sheet having a front surface, a back side, a first direction and a second direction, said first direction being perpendicular to the second direction, and cutting a retroreflecting stripe from said cube-corner retroreflecting sheet in the second direction.
