Abstract

La présente invention concerne un procédé de production d'un laquage multicouche, selon lequel une couche de laque de base ou plusieurs couches de laque de base se succédant directement sont produites directement sur un substrat revêtu d'une première couche, une couche de laque transparente est produite directement sur la couche de laque de base unique ou sur la couche de laque de base supérieure, puis la ou les couche(s) de laque de base et la couche de laque transparente sont durcies ensemble. Soit une dispersion aqueuse (D1) contenant un polyamide (PA) doté d'un indice d'acidité allant de 5 à 60 mg KOH/g, soit une dispersion aqueuse (D2) contenant un polyamide (PA) et un cire d'amide (AW), est ajoutée à au moins l'une des laques de base directement avant l'application.
