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.

First claim

What is claimed is:

1. 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.

2. The multi-layer coating of claim 1 , wherein the 1,1-di-activated vinyl compound comprises:
a dialkyl methylene malonate;
a diaryl methylene malonate;
a multifunctional form of a dialkyl methylene malonate; or
a multifunctional form of a diaryl methylene malonate; or
a combination of any thereof.

3. The multi-layer coating of claim 1 , wherein the 1,1-di-activated vinyl compound comprises:
diethyl methylene malonate; and
a multifunctional form of diethyl methylene malonate comprising a transesterification adduct of diethyl methylene malonate and at least one polyol.

4. The multi-layer coating of claim 3 , wherein the transesterification adduct of diethyl methylene malonate and at least one polyol comprises a transesterification adduct of diethyl methylene malonate and a diol.

5. The multi-layer coating of claim 4 , wherein the diol comprises an alkane diol.

6. The multi-layer coating of claim 5 , wherein the alkane diol comprises 1,5-pentane diol and/or 1,6-hexanediol.

7. The multi-layer coating of claim 1 , wherein the first coating layer comprises a polymerization reaction product of the 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof.

8. The multi-layer coating of claim 1 , wherein the polymeric resin comprises a carbamate-functional resin, an epoxy-functional resin, an amino-functional resin, a siloxane resin, a melamine resin, a phenolic resin, or a combination thereof.

9. The multi-layer coating of claim 1 , wherein the polymeric resin comprises a carbamate-functional resin.

10. The multi-layer coating of claim 1 , wherein the polymeric resin comprises a carbamate-functional acrylic resin.

11. The multi-layer coating of claim 1 , wherein the polymeric resin comprises a carbamate-functional resin and a hydroxy-functional acrylic resin.

12. The multi-layer coating of claim 1 , wherein the second coating layer further comprises a melamine-formaldehyde resin.

13. The multi-layer coating of claim 1 , further comprising a third coating layer, wherein the first coating layer is applied over at least a portion of the third coating layer.

14. The multi-layer coating of claim 13 , wherein the third coating layer is formed from a coating composition comprising an amine compound.

15. The multi-layer coating of claim 14 , wherein the coating composition forming the third coating layer further comprises a polyester resin, an acrylic resin, and a melamine-formaldehyde resin.

16. An article coated with the multi-layer coating of claim 1 , wherein the article comprises the substrate.

17. The article of claim 16 , wherein the article comprises vehicle components, components of free-standing structures, automotive substrates, industrial substrates, aircraft components, watercraft components, packaging substrates, aircraft components, watercraft components, packaging substrates, wood flooring, furniture, apparel, electronics, glass, transparencies, sports equipment, and/or appliances.

18. A process for coating the substrate with the multi-layer coating of claim 1 , the process comprising:
applying the first coating layer over at least a portion of the substrate;
applying the second coating layer over at least a portion of the first coating layer; and
curing the applied first coating layer and the applied second coating layer.

19. A process for coating the substrate with the multi-layer coating of claim 13 , the process comprising:
applying the third coating layer over at least a portion of the substrate;
applying the first coating layer over at least a portion of the third coating layer;
applying the second coating layer over at least a portion of the first coating layer; and
curing the applied first coating layer, the applied second coating layer, and the applied third coating layer.
