Abstract

A compressible substrate coated at least in part with a waterborne coating composition comprising at least one base neutralized active hydrogen containing film-forming resin and a water dispersible carbodiimide crosslinker capable of reacting with the film-forming resin to form a crosslinked film is disclosed. An article of manufacture having at least two different flexible substrates coated at least in part with such a coating is also disclosed.

First claim

What is claimed:

1. A compressible coated substrate comprising a substrate coated at least in part with a waterborne coating composition comprising:
a. at least one base neutralized active hydrogen containing film-forming resin; and
b. a water dispersible carbodiimide crosslinker capable of reacting with the film-forming resin to form a crosslinked film wherein the water dispersible carbodiimide is a water dispersible oligomeric carbodiimide and/or a water dispersible polymeric carbodiimide, the water dispersible carbodiimide crosslinker comprises carbodiimide linkages, urethane linkages and terminal urea-linked polyether groups; and
c. a water dispersible polyisocyanate.

2. The substrate of claim 1 , wherein the total neutralization of the base neutralized active hydrogen containing film-forming resin is between 60 to 170 percent.

3. The substrate of claim 1 , wherein the active hydrogen containing film-forming resin comprises a polyurethane.

4. The substrate of claim 1 , wherein the amount of water dispersible polyisocyanate in the waterborne coating composition ranges from about 5 to about 50 weight percent resin solids based on total resin solids.

5. The substrate of claim 1 , wherein the active hydrogen containing film-forming resin has a number average molecular weight greater than 500 as determined by gel permeation chromatography using a polystyrene standard.

6. The substrate of claim 1 , wherein the substrate comprises foam.

7. The substrate of claim 6 , wherein the foam comprises ethylene vinyl acetate foam.

8. The substrate of claim 6 wherein the foam comprises thermoplastic urethane foam.

9. The substrate of claim 1 , wherein the substrate comprises a textile.

10. The substrate of claim 1 , wherein the substrate comprises a polymeric bladder filled with air.

11. The substrate of claim 6 in the form of footwear.
