STAIN RESISTANT RETROREFLECTIVE ARTICLES
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.
