Abstract: A photoluminescent retroreflective article includes a retroreflective layer including multiple cube corner elements that collectively form a structured surface that is opposite a major surface and a conforming layer having a first region and a second region wherein the second region is in intimate contact with the structured surface and the first region forming a low refractive index layer between the conforming layer and the structured surface of the retroreflective layer. The conforming layer is separated from the structured surface at the first region by a barrier layer. A photoluminescent layer is disposed on the conforming layer.
Abstract translation: 光致发光的回射制品包括一个包括多个立体角元件的回射层，它们共同形成与主表面相对的结构化表面和具有第一区域和第二区域的适形层，其中第二区域与结构化表面紧密接触， 第一区域在适形层和回射层的结构化表面之间形成低折射率层。 通过阻挡层将适形层与第一区域处的结构化表面分离。 光致发光层设置在一致层上。
