  • Publication number: 20160245966
    Abstract: Methods for preparing retroreflective articles include providing a thermoplastic polymeric carrier layer, partially embedding transparent microspheres into the surface of the carrier layer so that the beads partially protrude from the surface of the carrier layer, depositing a metal reflective layer on the microspheres, applying a treatment solution to the metal layer, and applying a bead bond layer to the treated metal layer, to form an intermediate article. Upon removal of the carrier layer, the deposited metal layer not in contact with the surface of the microspheres remains present on the carrier layer, to form retroreflective articles with a discontinuous layer of reflective metal disposed only on the surface of the transparent microspheres.
