Abstract

See full text

Retroreflective articles and appliqués include a first binder layer with a first major surface and a second major surface, a retroreflective layer including a plurality of retroreflective elements at least partially embedded in the first major surface of the first binder layer, a second binder layer adhered to the second major surface of the first binder layer, and a substrate layer attached to the second binder layer. The first binder layer is a non-thermoplastic crosslinked (meth)acrylate-based copolymer. The second binder layer is a moisture-cured urethane-based polymer. The first binder layer and the second binder layer include functional groups capable of co-reacting to form a chemical bond. The retroreflective appliqués can be attached to clothing articles.
