Abstract
A prismatic retroreflective article comprising a transparent polymeric body portion having an elastic modulus less than about 13×10pascals, and a layer of internally reflecting open air-exposed cube-corner optical elements having an elastic modulus greater than about 14×10pascals and comprising a polymer having covalently-bound fluorine or silicon. The traditionally-employed rear cover film may be eliminated (thereby reducing cost, weight, stiffness and retroreflectivity loss due to seal leg formation), and retroreflectivity under wet conditions, dirty conditions, or both wet and dirty conditions can be at least partially maintained.
