Abstract

L'invention concerne un procédé d'élimination d'un substrat recouvert d'un revêtement organique formé par un gel ionogène, dans lequel un revêtement organique humide ou séché, mais pas encore filmé sur le substrat, est traité avec une solution aqueuse d'un sel de métal du premier groupe principal de la classification périodique des éléments, un agent complexant et/ou un composé basique ayant un pH > 10.
