Encapsulated flattop retroreflective sheeting and method for producing the same |
摘要 |
A hermetically sealed retroreflective sheeting having improved resistance to delamination and improved brightness comprising a monolayer of microspheres supported in a layer of binder material, a layer of reflective material disposed behind said microspheres, and a cover film disposed in spaced relation in front of the microspheres. The cover film is in, at most, tangential contact with the microspheres. The binder material forms a network of walls surrounding individual microspheres and is in adherent contact with the cover film. Each microsphere is "exposed", i.e., air-incident.
