发明名称 Method for making retroreflective articles having polymer multilayer reflective coatings
摘要 A method for making retroreflective articles that have a layer of optical elements and a multilayer reflective coating disposed on the optical elements. The reflective coating reflects light back into the optical elements so that it can be returned toward the light source. The multilayer reflective coating has at least one polymer layer made by condensing a curing a pre-polymer vapor.
