Patent ID: 7288514

Claim:
A composition comprising: a. an associative complex comprising: i. a water soluble and/or water dispersible polymer; ii. at least one polymeric fluorosurfactant capable of forming an associative complex with said polymer, wherein said polymeric fluorosurfactant comprises a fluorosurfactant derived from polymerization of a fluorinated oxetane; b. optionally, a dispersant, and; c. optionally, a liquid carrier, wherein the associative complex forms an invisible film upon a surface of a substrate wherein said film is less than 500 nanometers in average thickness; wherein the associative complex molar ratio parameter, R, is greater than 0 to about 20, and wherein said associative complex is selected from I) (A) said polymer comprising a charged and/or polarizable first constituent; and (B) said polymeric fluorosurfactant comprising a charged/and or polarizable second constitutent; wherein said second constituent bears a charge opposite to that of said first constituent.
