ABSTRACT:
A retroreflective article (10) has retroreflective elements (12) partially embedded in a binder layer (14) that contains a solid polyurethane. The polyurethane includes soft segments, hard segments, silicon moieties, and urethane moieties. The specific chemical identities and relative amounts of the segments and moieties are sufficient to impart desired high elongation and low modulus to the polymer. The inventive retroreflective article is capable of demonstrating extraordinary laundering durability under industrial wash conditions and tumble and tunnel drying.
