Abstract
A retroreflective article that exhibits high retroreflective efficiency in response to light incident on the sheeting at high angles of incidence is disclosed. A retroreflective article includes a body portion having a base surface and a structured surface opposite the base surface. The structured surface includes a plurality of retroreflective cube corner elements defined by two intersecting groove sets. Each cube corner element has three tetragonal optically reflective faces that intersect to define a cube corner apex and two tetragonal non-optical faces that intersect along an edge. The symmetry axes of the cube corner elements are substantially parallel.
