Abstract: Retroreflective articles include a layer of optical elements (110,120,130), embedded in a bead bond layer (140). The optical elements include transparent microspheres (110), at least one colored polymeric layer (120) covering the transparent microspheres, and a reflective layer (130) 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.
