RETROREFLECTIVE ARTICLE AND METHOD OF MAKING SAME |
摘要 |
A retroreflective article has first (32) and second (34) segments each compr ising a binder layer and a multitude of microspheres (36 ) partially embedded in the front surface of the binder layer (42). The first segment also has an opaque reflective metal layer (38) d isposed on the embedded portions of the microspheres; whereas, the second segment la cks such an opaque reflective metal layer and thereby allows the color of the underlying binder layer to be seen from the front si de of the retroreflective article. The first and second segments display noticeably different colors under daytime lighting conditions, and e ach possesses a distinctly different retroreflective eff iciency when viewed under retroreflective lighting conditions. The first and second segme nts therefore stand out in contrast to each other to enh ance the conspicuity of the retroreflective article.
