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. An article of manufacture comprising:
a) a first substrate comprising a first flexible material; and
b) a second substrate comprising a second flexible material different from the first flexible material,

wherein at least a portion of the first substrate and at least a portion of the second substrate are coated with a waterborne coating composition comprising:
i) at least one base neutralized active hydrogen containing film-forming resin;
ii) 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 urea linkages; and
iii) a water dispersible polyisocyanate.

2. The article of manufacture of claim 1 , wherein the active hydrogen containing film-forming resin comprises a polyurethane.

3. The article of manufacture of claim 1 , wherein the first and second substrates independently comprise natural leather, synthetic leather, vinyl, nylon, thermoplastic urethane, fabric, foam and/or rubber.

4. A footwear comprising the article of manufacture of claim 3 .

5. The article of manufacture of claim 1 , wherein the first substrate comprises foam and the second substrate comprises synthetic and/or natural leather.

6. The article of manufacture of claim 1 , wherein the coating further comprises a colorant.

7. The article of manufacture of claim 1 , wherein the article of manufacture is footwear.

8. The article of manufacture of claim 7 , wherein the footwear is an athletic shoe.

9. The article of manufacture of claim 1 , wherein the first and/or second substrates comprise a polymeric bladder filled with air.
