Claims
- 1. A coating composition comprising:
- an aqueous dispersion comprising one or more linear aliphatic urethane resins;
- an anionic surfactant having a phosphate substituent; and
- a cross-linking agent capable of facilitating the cure of said urethane.
- 2. The coating composition of claim 1 wherein at least one of said resins possesses at least two acid group substituents.
- 3. The coating composition of claim 2 wherein each of said resins possesses at least 20 acid group substituents.
- 4. The coating composition of claim 1 wherein said anionic surfactant is a fluoro-surfactant.
- 5. The coating composition of claim 2 wherein said cross-linking agent is a carboxyl reactive cross-linking agent.
- 6. The coating composition of claim 5 wherein said cross-linking agent is an aziridine derivative.
- 7. The coating composition of claim 1 additionally comprising a non-ionic surfactant.
- 8. The coating composition of claim 7 wherein said non-ionic surfactant is a fluoro-surfactant.
- 9. The coating composition of claim 2 wherein said aqueous dispersion additionally comprises at least one co-solvent capable of buffering the dispersion.
- 10. The coating composition of claim 9 wherein said co-solvent is selected from the group consisting of triethylamine, N-methyl pyrrolidone and mixtures thereof.
- 11. The coating composition of claim 9 wherein said aqueous dispersion has a pH ranging from above 7 to about 10.
