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.

Abstract: Retroreflective articles include transparent microspheres (120) protruding from a bead bond layer (140), with reflective metal layers (130) coated on a portion of the transparent microspheres. Retroreflective articles with anti-staining properties have bead bond layers that contain one or more corrosion inhibiting compounds. At least a portion of the one or more corrosion inhibiting compounds migrates through the reflective metal layer to passivate the exposed metal surface of the reflective metal layer.

Abstract: Methods for preparing retroreflective articles include providing a thermoplastic polymeric carrier layer, partially embedding transparent microspheres into the surface of the carrier layer so that the beads partially protrude from the surface of the carrier layer, depositing a metal reflective layer on the microspheres, applying a treatment solution to the metal layer, and applying a bead bond layer to the treated metal layer, to form an intermediate article. Upon removal of the carrier layer, the deposited metal layer not in contact with the surface of the microspheres remains present on the carrier layer, to form retroreflective articles with a discontinuous layer of reflective metal disposed only on the surface of the transparent microspheres.
Abstract translation: 用于制备回射制品的方法包括提供热塑性聚合物载体层，将透明微球部分地嵌入载体层的表面，使得珠粒从载体层的表面部分地突出，在微球上沉积金属反射层，施加处理 对金属层的溶液，以及将珠接合层施加到经处理的金属层上，形成中间制品。 在移除载体层时，不与微球表面接触的沉积金属层保留在载体层上，以形成具有仅在透明微球表面上布置的不连续的反射金属层的逆反射制品。

Abstract: Retroreflective articles include a layer of optical elements, and a polyurethane bead bond layer. The optical elements include transparent microspheres, and at least one reflective layer. The polyurethane bead bond layer is the reaction product of a reaction mixture of at least one aliphatic polycarbonate polyol and at least one polyisocyanate, and the reaction mixture is free of polyols containing unsaturated groups. The retroreflective articles have improved wash durability.
