ABSTRACT:
A retroreflective article 10 includes retroreflective elements 12 partially embedded in a binder layer 14 that comprises a polyester polyurethane polymer. The polyurethane polymer is a reaction product of (i) a polyester polyol that contains an aromatic nucleus and has at least two isocyanate groups bonded non-conjugatively to the aromatic nucleus, and (ii) a polyisocyanate. A retroreflective article that employs a binder layer of this kind demonstrates extraordinary laundering durability under stringent wash conditions.
