AbstractDisclosed is a method of detecting a cured silicone coating applied to a paper substrate or the like in web form, comprising adding an effective amount of a fluorescent pigment to the silicone coating formulation to be applied to the substrate, applying the coating to the substrate, curing the silicone coating, scanning the coated surface of the substrate with a UV light source, and detecting the fluorescence of the coating. Also disclosed is the coated paper product with which the method of the invention can be employed.
