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 comer 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.
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.
