发明名称 FLUORESCENT RED-ORANGE RETROREFLECTIVE SHEETING
摘要 <p>A fluorescent red-orange retroreflective article includes a polymeric matrix and at least one fluorescent dye added in an amount that provides the article with a red-orange color under daytime lighting conditions. The article also includes cube corner elements disposed at a back side of the polymeric matrix. The article can exhibit a retroreflectivity of at least 350 or 500 cd/(lux.m2), and a brightness Y of at least 20, 30, or 35. The article can exhibit a color within a preferred red-orange color space bounded by CIE chromaticity coordinates (0.560, 0.380), (0.580, 0.355), (0.633, 0.366) and (0.610, 0.390). The dye conditions associated with such enhanced performance tend to correspond to that particular preferential color space being disposed at the upper right portion of the overall red-orange fluorescent color space.</p>
