Asymmetric cube corner article

摘要

A cube corner article has a plurality of geometric structures formed by at least three intersecting groove sets. Each geometric structure has three faces arranged as a cube corner element. Some of the geometric structures also have a fourth face which is not a part of a cube corner element. At least one of the grooves in the three intersecting groove sets has a first and second side surface extending uniformly from a groove vertex, the first side surface forming one of the three faces and the second side surface forming the fourth face.
