RETROREFLEKTIERENDE FAHRBAHNMARKIERUNGEN FUER NAESSE

摘要

Retroreflective articles, for example in the form of pavement markers or retroreflective elements, exhibit both wet and dry retroreflectivity by using a plurality of Type A microspheres and a plurality of Type B microspheres partially embedded in a binder layer containing specular pigments. The Type A and Type B microspheres have different average indices of refraction.
