Abstract
In one embodiment, the present invention relates to a label containing a substrate layer, and a security coating on at least one side of the substrate layer containing: from about 50% to about 99.999% by weight of a film forming material, and from about 0.001 % to about 5% by weight of at least one taggant compound, wherein the taggant compound is substantially uniformly dispersed within the film forming material. In another embodiment, the present invention relates to a method of authenticating a product, involving: affixing a label to the product, the label containing a substrate layer, and a security coating on at least one side of the substrate layer containing: from about 50% to about 99.999% by weight of a film forming material, and from about 0.001% to about 5% by weight of at least one taggant compound, wherein the taggant compound emits light of a known wavelength after irradiated with light of a first wavelength; irradiating the product with light of the first wavelength; determining whether or not the product emits light of the known wavelength; and authenticating the product if the wavelength of the light emitted by the product is substantially the same as the known wavelength.
