METALIZED MICROPRISMATIC RETROREFLECTIVE FLIM WITH IMPROVED OBSERVATION ANGULARITY

摘要

One aspect of the present disclosure provides microprismatic retroreflective film that includes a substrate and metalized microprisms located on the substrate. At least a portion of the metalized microprisms are forward-tilted microprisms, and at least a portion of the forward-tilted microprisms are arranged in matched pairs and are aligned with the plane of optical axis tilting aligned at an angle ranging from about 10 to 80 degrees with an edge of the microprismatic retroreflective film.
