摘要: Cube-corner retroreflective article having improved divergence profiles. The three lateral reflecting faces of the cube-corner elements are formed by intersecting sets parallel V-shaped grooves, and at least one includes, in a repeating pattern, two groove side angles that differ from another. Thereby array is divided into sub-arrays each comprise plurality distinctive shapes retroreflect incident light distinctively shaped patterns.
