Abstract
Abstract 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.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
145 words
A decorative, ornamental bead-coated sheet that is durable, flexible and easy to handle and which may be readily affixed to the surfaces of less flexible more rigid sheet material, said bead-coated sheet comprising: a. a flexible sheet substrate; b. a layer of a flexible aqueous emulsion resin adhesive coated on one surface of said flexible sheet substrate; c. a layer of transparent beads formed from a plurality of individual beads treated with a silane coupling agent and embedded into said layer of adhesive so that a portion of each of said beads projects outwardly from the surface of said adhesive, and d. a flexible transparent cover coat overlaying said layer of beads to conform to the surface projections of said beads without obscuring said surface projections so that the surface of said finished sheet has a configuration corresponding to the surface projections of said beads.
Claim 2
Dependent Claim
145 words
A decorative, ornamental bead-coated sheet that is durable, flexible and easy to handle and which may be readily affixed to the surfaces of less flexible more rigid sheet material, said bead-coated sheet comprising: a. a flexible sheet substrate; b. a layer of a flexible aqueous emulsion resin adhesive coated on one surface of said flexible sheet substrate; c. a layer of transparent beads formed from a plurality of individual beads treated with a silane coupling agent and embedded into said layer of adhesive so that a portion of each of said beads projects outwardly from the surface of said adhesive, and d. a flexible transparent cover coat overlaying said layer of beads to conform to the surface projections of said beads without obscuring said surface projections so that the surface of said finished sheet has a configuration corresponding to the surface projections of said beads.
