ABSTRACT:
Curable multilayer coated plastic substrates are provided having enhanced gasoline resistance and topcoat adhesion. The plastic is coated with a primer layer which is either a chlorosulfonated grafted polypropylene polymer or a mixture of a chlorinated grafted propylene polymer and a chlorosulfonated olefin polymer and which is free of crosslinking agents for the chlorosulfonated polymer. The primer layer is coated with a coating layer having free hydroxyl, primary amino, or secondary amino groups capable of reacting with the chlorosulfonyl groups of the primer layer.
