More Information
Summary:Retroreflective articles include a layer of optical elements, embedded in a bead bond layer. The optical elements include transparent microspheres, at least one colored polymeric layer covering the transparent microspheres, and a reflective layer covering the colored polymeric layer. The polymeric layer includes at least one nanopigment. The transparent microspheres have a diameter range of 80-120 micrometers, with at least 75% of the transparent microspheres having a diameter range of 85-105 micrometers.
