ABSTRACT:
A retroreflective article10has a body portion14and a multitude of cube-corner elements12that project from a rear side20of the body portion14. The body portion14includes a body layer18that contains a light-transmissible polymeric material having an elastic modulus less than 7×108pascals. The cube-corner elements12contain a light transmissible polymeric material having an elastic modulus greater than 16×108pascals. A retroreflective article of this construction can be highly flexed while maintaining good retroreflective performance.
