Abstract
Polymer emulsion is very useful for inkjet inks because it can treat media surface at the same time of printing and improve the print durability and then enlarge the application of inkjet printer. But for the thermal inkjet system, polymer emulsion is likely to make aggregates by heating of the ejection and make serious kogation on the heater. To avoid this thermal problem, heat stable polymer emulsion is necessary.In this paper, several kinds of polymer emulsion are investigated for thermal inkjet inks and low molecular polyester emulsion, polyacrylamide emulsion, and acrylic polymer emulsion with silicone graft side chain are found to show good heat stability for thermal inkjet systems. Especially, the introduction of silicone graft side chain improves the heat stability of the polymer emulsion with only 10% modification and is favorable for further polymer designing.
