<p>A method for preparing multi-layer protective coatings having enhanced durability with easy removability under conventional stripping conditions is disclosed. The invention is based on applying to a substrate, a first-coating composition that is removable, followed by application of a second-coating composition that is highly durable but not readily removable. Preferred second-coating compositions are based on polymers that provide highly crosslinked 'non-removable' (under conventional stripping conditions) coatings if used alone. The resultant multi-layer coating compositions provide enhanced detergent resistance while retaining easy overall removability properties.</p> |
