A retroreflective sheet structure () comprising a transparent layer () having a front light-receiving surface () and a rear retroreflecting surface (). Light incident on the front surface () will pass through the layer (), impinge on the rear retroreflective surface () and reflect back out through the front surface () in a predetermined direction. An identifying indicia () is chosen and then formed on the retroreflecting surface (). This indicia () can be used for identification purposes, even years after an end product incorporating the reflective sheet structure () has been out in the field.

Abstract:
A retroreflective sheeting () comprising a cube layer () having a front light-receiving surface () and a rear retroreflecting surface (), and a metallic layer () covering the rear retroreflecting surface (). The rear surface () comprises an array of retroreflective elements () and diffusing patches () within such array (without retroreflective elements ()). The metallic layer () covers the retroreflective elements () and the diffusing patches (), whereby diffusing patches () scatter incoming light increasing daytime brightness to a desired level.

An infrared light transmission film includes a polymer matrix and at least one red colorant, blue colorant, and yellow colorant that are uniformly dispersed in the polymer matrix at amounts effective to allow transmission through the film of at least about 85% of light with wavelengths over about 800 nm while blocking transmission of at least about 90% of light with wavelengths less than about 750 nm.

International Classification:
B29D 11/00
US Classification:
264 25
Abstract:
A method of making an array () of aberrated optical elements (). The method comprises the steps of providing a substrate having a first surface with forming elements thereon, and controlled working a localized region on the first surface of the substrate. The controlled working is of a magnitude sufficient to aberrate one or more of the forming elements in an affected site surrounding the localized region.

US Classification:
359530, 264 134
Abstract:
A rotationally insensitive, retroreflective prismatic sheeting and method of manufacture is provided. The sheeting includes discrete clusters of cube corners that are separated from one another on all sides by a textured surface. Each of the cube corners in each cluster has a base edge that is not collinear or parallel with the base edges of cube corners on either side of it. The array of cube corners clusters is rulable, and the cube corners have different orientations. Four or more of the cube corners in each cluster may have edges that converge into a central point within the cluster, and the cube corners of the clusters may include at least two symmetrical pairs of cube corners. The shapes of the cube corner clusters may be polygonal, and all of the cube corners may share a common vertex located at the center of the polygonal shape.
