Abstract
A retroreflector and a process for preparing it are disclosed characterized in that the retroreflector has a retroreflecting area consisting of rows of integrated, trihedral, light-reflecting units of varying geometric configurations which are so arranged as to provide substantially the same wide angle response to incident light throughout the entire retroreflective area. Essentially, the widths of adjacent rows of trihedral, light-reflecting units vary to form a pattern which may be repeated throughout the retroreflective area.
