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.
Claims11
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.
