<P>PROBLEM TO BE SOLVED: To provide a retroreflective article that exhibits suitable retroreflective luminance under dry and dynamic wet conditions. <P>SOLUTION: This retroreflective article that exhibits suitable retroreflective luminance under dry and dynamic wet conditions is provided. The article includes an enclosed-lens retroreflective sheeting that, under dry conditions, exhibits a coefficient of retroreflective luminance of about 40(mcd/m<SP>2</SP>)/lux as measured by ASTM D 4061-94 and, under dynamic wet conditions the sheeting increases in coefficient of retroreflective luminance. The article further includes a plurality of retroreflective elements partially embedded in a light transmissible bonding layer on the front, reflective surface of the retroreflective sheeting. <P>COPYRIGHT: (C)2010,JPO&INPIT |
