Abstract:
Retroreflective article and precursor articles formed during the preparation of the retroreflective articles are provided. Also, methods of making both the precursor articles and the retroreflective articles are provided. The retroreflective articles and the precursor articles contain a reflective layer that includes both a reflective metal and a polymeric blend. The polymeric blend includes both a fluorinated polymer and a (meth)acrylate polymer. The retroreflective articles typically have anti-staining properties, anti-corrosion properties, or both.
