Abstract
A retroreflective adhesive material has a retroreflective composition including retroreflective elements protruding from a first surface of a binder layer. A carrier web is secured to a second surface of the binder layer. The retroreflective adhesive material also includes a pressure sensitive adhesive layer. In certain preferred embodiments, a removable release liner covers the pressure sensitive adhesive. Retroreflective pattern elements are formed by the retroreflective composition, and the retroreflective material is clean-edge hand tearable. In certain embodiments, the carrier web is formed of fabric.
