Beschreibung
Zusammenfassung:	The present invention relates to a functional coating obtained from an aqueous coating composition, which composition comprises a pigment and a polymeric binder, wherein the binder has a weight average molecular weight of from 2000 to 50000 g/mole, and an acid value of 40 to 250, and wherein the binder is a polyester comprising a side group introduced by a Diels-Alder and/or pericyclic Ene-reaction, wherein the side group contains an ionic group and/or an ion-forming group. 本发明涉及由水性涂料组合物获得的功能涂层，所述组合物包含颜料和聚合物粘结剂，其中所述粘结剂具有2000至50000g/mol的重均分子量和40至250的酸值，且其中所述粘结剂是包含通过狄尔斯-阿尔德反应和/或周环烯反应引入的侧基的聚酯，其中所述侧基含有离子基团和/或离子形成基团。
