More Information
Summary:Retroreflective articles having multilayer films are useful for commercial graphics and retroreflective products, such as roll-up signs for highway transportation safety. The articles comprise multilayer films having at least one layer of polyurethane and at least one layer of a copolymer of alkylene and at least one non-acidic, polar co-monomer. Articles having the new multilayer films provide the same or improved performance, are less expensive, and offer improved methods for manufacturing, when compared to prior articles.
