More Information
Summary:Retroreflective articles of the invention comprise a continuous base layer and a multi-color polymeric top layer. The invention also includes methods of making such retroreflective articles. The retroreflective articles of the invention provide excellent daytime contrast while maintaining nighttime retroreflectivity. Variously colored segments of polymer are directly and either sequentially or simultaneously coated onto a continuous backing to form a multi-colored top layer. Durability over existing multi-colored retroreflective articles is enhanced by use of a continuous base layer.
