Summary: | A new embedded-lens retroreflective sheeting which exhibits superior properties, including superior angularity, and which is made by a new method of manufacture involving lamination techniques. Microspheres are embedded into a first polymeric layer to less than one-half the average diameter of the microspheres, and a pre-formed spacing film is laminated to the microsphere covered surface of the first layer so as to obtain conformation of the spacing film in a substantially constant thickness over a useful portion of the back surface of the microspheres. |
