METHOD OF MAKING RANDOMLY ORIENTED CUBE-CORNER ARTICLES

摘要

Retroreflective cube-corner articles having randomly oriented cube-corner elements exhibiting rotational symmetry and entrance angularity like microsphere-based sheeting but having increased retroreflective efficiency from cube-corners. The inventive sheeting may contain cube-corner elements typically of different cube-corner geometries, different cube-corner dimensions, and different central axis heights. The cube-corner elements are positioned randomly and are typically not adjacent to one antoher. Also, methods of making such articles are provided.
