PROBLEM TO BE SOLVED: To provide a method for marking in which markers are readily detectable, e.g., by mass spectroscopy, upon solvent extraction and separation of an aqueous composition, such as traffic paint, from the composition or from a dried or cured coating, film or layer thereof.SOLUTION: An aqueous polymer composition contains one or more aqueous polymers, and one or more, or preferably two or more, markers selected from a C-Calkyl phenyl ether having a group represented by formula (1) defined by Ph(R)(OR), where Ph is a C6-9 aromatic ring-containing group; Ris a C-Calkyl group; Ris a C-Calkyl group; m is an integer from 0 to 5; n is an integer from 1 to 3; and (m+n) is an integer from 1 to 6.SELECTED DRAWING: None 【課題】路面塗料等の水性組成物を、該組成物から、又はその乾燥或いは硬化したコーティング、膜、若しくは層から溶媒抽出及び分離されると、例えば質量分析によって容易に検出可能である、マーキングするための方法の提供。【解決手段】１つ以上の水性ポリマーと式（１）で表される基をを有する１つ以上、又は好ましくは２つ以上のＣ１−Ｃ１２アルキルフェニルエーテルから選択されるマーカーを含有する、水性ポリマー組成物。Ｐｈ（Ｒ２）ｍ（ＯＲ１）ｎ（１）（ＰｈはＣ６〜９の芳香環含有基；Ｒ１はＣ１−Ｃ１２アルキル基；Ｒ２はＣ１−Ｃ１２アルキル基；ｍは０〜５の整数；ｎは１〜３の整数；（ｍ＋ｎ）は１〜６の整数）【選択図】なし
