Rueckstrahlendes Material und seine Herstellung

摘要

Retroreflective material is provided by a composite synthetic plastic structure having a body portion with one smooth surface and another surface from which project a multiplicity of separately formed, minute cube corner formations having a side edge dimension of less than 0.025 inch. The cube corner formations may have a reflective coating thereon, and an adhesive layer and release paper to permit facile mounting on a support surface. Light rays entering through the smooth surface pass into the cube corner formations and are reflected back substantially parallel to the path of entry.
