ABSTRACT:
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.
