Abstract: The present invention provides cube corner retroreflective articles that have improved retroreflective performance in at least one plane, and preferably in two or more planes. A preferred article is a retroreflective sheeting that includes a structured surface having at least one array of cube corner elements oriented at a predetermined angle relative to the edge of the article. The angle is selected to align one broad plane of entrance angularity approximately parallel with the edge of the sheeting and another broad plane of entrance angularity approximately perpendicular to the edge of the sheeting. Individual cube corner elements on the structured surface are canted to yield an isosceles base triangle or a scalene base triangle. Additionally, the structured surface may include a plurality of cube corner element arrays arranged in a tiled fashion to yield greater than two planes of broad entrance angularity.

Abstract: Retroreflective sheeting and a method of forming and using such sheeting is described in which a base body is formed with closely spaced microsprisms. The microprisms have window facets extending across the body portion in a plane with retroreflecting facets extending from the window facets to apices. Either the base body surfaces or the side facets are textured to deviate the path of light entering and/or retroreflected from the prisms to provide a uniform distribution of light.

Abstract: Polymeric sheeting materials directly thermally printed upon with a thermal printing system and a resin-based colorant/binder. The polymeric sheeting materials comprise a core sheet and a thermally print receptive surface on the core sheet. The thermally print receptive surface may be formed from compositions comprising a polyurethane dispersion. The thermally print receptive surface is smooth, transparent, durable, and weatherable. Signage articles made from the polymeric sheeting materials of the invention may be configured to have the desired combination of frangibility, durability, retroreflectivity and/or low production cost. Frangible, retroreflective signage articles may be produced from the polymeric sheeting materials and may have durable variable information thermally and variably printed directly on the articles.

Abstract: The present invention provides an improved cube-corner retroreflective article that exhibits a wide range of retroreflective angularity in multiple viewing planes. The present invention provides cube-corner retroreflective elements having a decreased size, as measured by the height of the cube corner, thereby decreasing the amount of canting required to achieve a given angularity. Alternatively, angularity can be enhanced by leaving the degree of canting constant and decreasing the size of the cube corner.
