Abstract
In general, the invention features a method of marking a product for identification in which a marker, composed of a low molecular weight hapten covalently bound to a compound, is associated with the product. Where the marker is non-deleterious to the product, inert with respect to the product, and not already associated with the product. The invention also features hapten markers produced by covalently binding a hapten to a functional monomer and subsequently polymerizing the hapten-labeled monomer to form a hapten-labeled polymer.
