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.

Abstract: Retroreflective articles include transparent microspheres (120) protruding from a bead bond layer (140), with reflective metal layers (130) coated on a portion of the transparent microspheres. Retroreflective articles with anti-staining properties have bead bond layers that contain one or more corrosion inhibiting compounds. At least a portion of the one or more corrosion inhibiting compounds migrates through the reflective metal layer to passivate the exposed metal surface of the reflective metal layer.
