Abstract
A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents are selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof; one or more binder resins; and one or more dyes. The ink composition is suitable for use in a thermal ink jet printer and the ink composition has a slow rate of kogation such that it is capable of being printed at least 10 million drops per nozzle from the thermal ink jet printer before drop weight of the ink composition is reduced by more than 10%.
Claims22
