Beschreibung
Zusammenfassung:	The present invention is directed to a phosphated epoxy resin comprising at least one terminal group comprising a phosphorous atom covalently bonded to the resin by a carbon-phosphorous bond or by a phosphoester linkage; and at least one carbamate functional group. The present invention is also directed towards aqueous resinous dispersions comprising the phosphated epoxy resin, methods of coating a substrate, coated substrates, and methods of making a phosphated epoxy resin. La présente invention concerne une résine époxy phosphatée comprenant au moins un groupe terminal comprenant un atome de phosphore lié de manière covalente à la résine par une liaison carbone-phosphore ou par une liaison phosphoester; et au moins un groupe fonctionnel carbamate. La présente invention concerne également des dispersions résineuses aqueuses comprenant la résine époxy phosphatée, des procédés de revêtement d'un substrat, des substrats revêtus, et des procédés de production d'une résine époxy phosphatée.
