The present invention provides aqueous polymer compositions containing one or more, or, preferably, two or more triphenylmethyl alkyl aryl ether markers having a formula (Ph3C)mAr(OR)n, wherein Ph isa phenyl group, Ar is an aromatic ring containing group having from six to twenty carbon atoms, R is a C1-C18 alkyl 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. 本发明提供水性聚合物组合物，其含有种或多种或优选地两种或更多种具有式(PhC)Ar(OR)的三苯甲基烷基芳基醚标记物，其中Ph为苯基，Ar为具有六个到二十个碳原子的含芳环基团，R为CC烷基，m为1到2的整数，并且n为1到4的整数。在溶剂提取和从所述水性聚合物组合物或其的干燥或固化的涂层、膜或层分离后，所述标记物可易于如通过质谱检测。
