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. La présente invention concerne un revêtement fonctionnel obtenu à partir d'une composition de revêtement aqueuse, ladite composition comprenant un pigment et un liant polymère, le liant ayant un poids moléculaire moyen en poids de 2 000 à 50 000 g/mol, et un indice d'acide de 40 à 250, et le liant étant un polyester comprenant un groupe latéral introduit par une réaction de Diels-Alder et/ou d'ène péricyclique, le groupe latéral contenant un groupe ionique et/ou un groupe formant des ions.
