摘要:
The present invention is directed to aqueous based ink compositions for ink jet printing on offset media and offset ink comprising various combinations of nonionic surfactants. Such formulations include effective amounts of an ink colorant and a nonionic surfactant having an HLB value from about 4 to 14. Optionally, additional nonionic surfactants, solvents, and binders can be added. In another formulation, an effective amount of an ink colorant, at least two nonionic surfactants, each being present at from about 0.01% to 10% by weight (preferably 0.01% to 2% by weight) and an effective amount of at least one binder (such as an acrylate binder) is disclosed.
