Abstract
The invention provides methods for increasing the recoverability of taggants from an object. The methods include the steps of incorporating a taggant into a solution; mixing the solution including the taggant with a perturbant to form a first perturbant taggant solution; mixing the first perturbant taggant solution with a polymer to form a second perturbant taggant polymer solution; and applying the second perturbant taggant polymer solution to at least a portion of the object to form a taggant-coated object. Methods for authentication of a taggant marked object are also provided.
