COATED SUBSTRATE

A coated substrate includes a coating layer extending over at least a portion of the substrate. The coating is obtainable from a coating composition comprising: (a) a polymeric binder; and (b) an eclosion reducer comprising a carboxylic acid reactive functional group. The coated portion of the subst...

Beschreibung
Zusammenfassung:	A coated substrate includes a coating layer extending over at least a portion of the substrate. The coating is obtainable from a coating composition comprising: (a) a polymeric binder; and (b) an eclosion reducer comprising a carboxylic acid reactive functional group. The coated portion of the substrate includes a pretreatment layer. The pretreatment layer may be obtained from a pretreatment composition comprising a trivalent chromium compound. The present invention extends to a method of coating a pre-treated substrate as well as to coated packages, such as metal cans. Un sustrato recubierto que comprende un recubrimiento que se extiende sobre al menos una parte del sustrato; el recubrimiento puede obtenerse a partir de una composición de recubrimiento que comprende (a) un aglutinante polimérico; y (b) un agente reductor de desprendimiento que comprende un grupo funcional reactivo de ácido carboxílico; la porción recubierta del sustrato comprende una capa de pretratamiento; la capa de pretratamiento puede obtenerse a partir de una composición de pretratamiento que comprende un compuesto de cromo trivalente; la invención se extiende a un método para recubrir un sustrato pretratado y un envase recubierto, tal como una lata de metal.
