Abstract
The present disclosure provides an ink comprising a fluorosurfactant-stabilized polymer latex, which is suitable for use in an indirect printing method.
Claims20
An ink for use in an indirect printing process comprising:
- water;
- a co-solvent;
- and
- a fluorosurfactant-stabilized polymer latex comprising a polystyrene copolymer latex having a glass transition temperature of from 55° C. to about 63° C., and a fluorosurfactant, wherein the fluorosurfactant is an anionic phosphate ester and does not covalently bind to the polymer latex, wherein the fluorosurfactant comprises a partially or fully fluorinated alkyl group having from 1 to 12 carbon atoms and a perfluoro telomer, and further wherein the fluorosurfactant is present in the ink in an amount from about 0.0001 percent to about 0.1 percent by weight based on the total weight of the ink.
