Abstract
The present invention provides aqueous polymer compositions containing one or more, or, preferably, two or more triphenylmethyl alkyl aryl ether markers having a formula (PhC)Ar(OR), wherein Ph is a phenyl group, Ar is an aromatic ring containing group having from six to twenty carbon atoms, R is a C-Calkyl group, m is an integer of from 1 to 2, and n is an integer of from 1 to 4. The markers are readily detectable, such as by mass spectroscopy, upon solvent extraction and separation from the aqueous polymer compositions, or from dried or cured coatings, film or layers thereof.
