and a dried or cured adhesive coating over at least a portion of one surface of the transparent substrate, wherein the dried or cured adhesive coating comprises a mixture of a polymeric binder and reflective flakes that are randomly dispersed in the dried or cured adhesive coating, wherein the reflective flakes make up less than 5% by weight of the dried or cured adhesive coating and are visible through the transparent substrate such that by the specific locations of all of the flakes a visually unique pattern is created. ### Claim 2 (depends on 1) The product security label of claim 1, wherein the polymeric binder comprises a pressure sensitive adhesive (PSA). ### Claim 3 (depends on 1) The product security label of claim 1, wherein the dried or cured adhesive coating comprises a dried or cured emulsion containing the reflective flakes, or a dried or cured solvent solution containing the reflective flakes. ### Claim 4 (depends on 1) The product security label of claim 1, wherein the dried or cured adhesive coating is cured using an electron beam radiation system, or an ultraviolet or light-emitting diode-based light system. ### Claim 5 (depends on 1) The product security label of claim 1, wherein the transparent substrate has an unprinted surface, and wherein the dried or cured adhesive coating is laminated to the unprinted surface of the transparent substrate. ### Claim 6 (depends on 1) The product security label of claim 1, wherein the transparent substrate has a printed surface, and wherein the dried or cured adhesive coating is laminated to the printed surface of the transparent substrate. ### Claim 7 (depends on 1) The product security label of claim 1, wherein the dried or cured adhesive coating is laminated to both surfaces of the transparent substrate. ### Claim 8 (depends on 7) The product security label of claim 7, wherein one surface of the transparent substrate is printed before the dried or cured adhesive coating is laminated. ### Claim 9 (depends on 1) The product security label of claim 1, further comprising a radiation-cured protective overcoat. ### Claim 10 (depends on 1) The product security label of claim 1, further comprising a hologram on or in the product security label. ### Claim 11 (depends on 1) The product security label of claim 1, wherein the reflective flakes are selected from the group of reflective flakes consisting of metal flakes, metallized flakes, flakes with an embossed optical grating, and flakes containing a diffraction pattern. ### Claim 12 (depends on 1) The product security label of claim 1, further comprising a release liner on a side of the dried or cured adhesive coating. ### Claim 13 (depends on 1) The security label of claim 1, further comprising a topcoat over a surface of the transparent substrate. ### Claim 14 (depends on 13) The product security label of claim 13, further comprising printing on or underneath the topcoat. ### Claim 15 (depends on 1) The product security label of claim 1, wherein at least some of the reflective flakes are diffractive. ### Claim 16 (depends on 1) The product security label of claim 1, wherein at least some of the reflective flakes are colored. ### Claim 17 (depends on 1) The product security label of claim 1, wherein at least some of the reflective flakes are metallized or metal. ### Claim 18 (depends on 1) The product security label of claim 1, wherein the reflective flakes make up 0.3% by weight of the dried or cured adhesive coating. ### Claim 19 (depends on 1) The product security label of claim 1, wherein the reflective flakes make less than 0.1% by weight of the dried or cured adhesive coating.
