More Information
Summary:The present disclosure provides a retroreflective film for removable application to a three-dimensional object. The film comprises a transparent film layer; a first transparent adhesive layer; a retroreflective layer comprising glass microspheres and a binder; a metalized coating layer comprising aluminum applied on the retroreflective layer; a removable adhesive layer having a peel force of 2 lbs/inch or less. When the film is elongated by 50% it retains at least 50% of its unstretched coefficient of retroreflection as measured at the 0.2 degree observation angle and −4 degree entrance angle. When the film is elongated by 50% it retains at least 50% of its unstretched gloss when measured at a 20 degree angle.
