More Information
Summary:The present invention provides a retroreflective sheeting including: optical elements arranged in substantially a monolayer; a spacing layer in which the optical elements are at least partially embedded; a specularly reflecting layer underlying the spacing layer; and a bead bond layer in which the optical 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 DEG C.
