摘要：
A retroreflective sheeting including: retroreflective elements (13) arranged in substantially a monolayer; a spacing layer (15) in which the retroreflective elements are at least partially embedded; a specularly reflecting layer (16) underlying the spacing layer; and a bead bond layer (14) in which the retroreflective elements are at least partially embedded. The bead bond layer includes an aminoplast-crosslinked polymer comprising urethane groups, wherein prior to crosslinking the polymer has a glass transition temperature (Tg) of less than about 0 °C.
