Ink composition for ink-jet printing

摘要

This invention concerns an ink composition for thermal ink-jet printing consisting of an aqueous solution, a co-solvent, a dye, a pH regulator, a viscosity modifier, a biocide and a mixture of three non-ionic surface-active agents, one of which is diethylene glycol mono-hexyl ether and the other two are fatty ethoxylate alcohols. This ink composition allows drying times to be reduced to under 2
