摘要：A retroreflective article includes a flat front surface, and a structured rear surface displaced from the flat front surface. The structured rear surface is provided with arrays of sets of three mutually perpendicular lateral triangular sides, and a plurality of trigonal linear prisms. The three lateral triangular sides have a common apex and uncommon linear base edges. The linear prisms are disposed along at least one of the linear base edges of the three lateral triangular sides.
