Sheet coated with beads and process for preparing same
摘要:
A sheet coated with beads and comprising a flexible sheet substrate and a transparent bead layer formed on the surface of the substrate integrally therewith, with an adhesive layer provided therebetween. Another bead-coated sheet comprises an elastic flexible sheet substrate, a hard transparent bead layer formed over the surface of the substrate with an adhesive layer interposed therebetween, a transparent cover coat layer integrally formed on the bead layer and a transparent top coat layer integrally formed on the cover coat layer and having lower hardness than the beads. The coat layers permit the bead layer to retain surface projections provided by the beads.
