Abstract
Acid-catalyzed curable coating compositions containing 1,1-di-activated vinyl compounds are described, including multi-layer coatings. Also provided are processes for coating substrates with coating compositions comprising 1,1-di-activated vinyl compounds. Also provided are coated articles comprising coatings formed from coating compositions comprising 1,1-di-activated vinyl compounds.
Claims19
A multi-layer coating for a substrate, the multi-layer coating comprising:
- a first coating layer configured to be applied over at least a portion of the substrate, wherein the first coating layer is formed from a coating composition comprising 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof, wherein the 1, 1-di-activated vinyl compound comprises a methylene dicarbonyl compound, a dihalo vinyl compound, or a dihaloalkyl disubstituted vinyl compound, or a multifunctional form of any thereof, or a combination of any thereof;
- and
- a second coating layer applied over at least a portion of the first coating layer, wherein the second coating layer is formed from a coating composition comprising a polymeric resin and an acid curing catalyst.
