Patent ID: 8188159

Claim:
An inkjet ink, comprising a composition made by combining: a. a colorant; b. an inkjet vehicle; and c. a polymeric material having a formula according to Formula I, Formula II, or a mixture thereof: wherein each R 1 polar group, independently, is selected from a group consisting of an anion-countercation; a cation-counteranion; an amphoteric group, and a non-ionic group; wherein each of the R f groups is independently selected from the group consisting of a linear fluorinated alkyl group and a branched fluorinated alkyl group, and wherein each of the R f groups has a main chain length ranging from about 1 to less than 6 carbon atoms; wherein each R f group, independently, has at least about 10% by number of the non-carbon atoms being fluorine atoms; wherein subscript n ranges from about 1 to about 5; subscript m ranges from 1 to 5; and B is a monomer selected from the group consisting of ethylene oxide, propylene oxide and butylene oxide; wherein a total of (x+(z−x)) in Formula I is in a range from about 2 to about 30; and wherein a total of (x+y+(z−x)) in Formula II is in a range from about 25 to about 45.
