CA 2322632

An undercoat composition comprises a film-forming synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal by a stripping composition of a top coat paint which is subsequently applied over the undercoat. A top coat composition for applying as the outer coating on a substrate comprises a film- forming synthetic resin having functional groups and a curing agent for crosslinking the synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal of the cured top coat by a stripping composition from a cured undercoat of similar composition which does not contain the said acidic aromatic polar organic compound.

L'invention concerne une composition de sous-couche. Cette composition comprend une résine synthétique feuillogène et contient un composé organique polaire aromatique acide non volatile, sous forme de sel ou d'acide libre. Ce composé permet d'enlever plus facilemen, à l'aide d'une composition de dépouillage, une couche de finition qui est appliquée ultérieurement sur la sous-couche. Une composition de finition prévue pour être appliquée comme couche extérieure sur un substrat comprend une résine synthétique feuillogène comportant des groupes fonctionnels et un agent de durcissement pour assurer la réticulation de la résine synthétique, et un composé organique polaire aromatique acide non volatile sous forme de sel ou d'acide libre. Ce composé permet d'enlever plus facilement la couche de finition durcie par une composition de dépouillage à partir d'une sous-couche durcie de même composition qui ne contient pas ledit composé organique polaire aromatique acide.
