<P>PROBLEM TO BE SOLVED: To provide an ink composition having increased stability and increased jettability, containing specific surfactants, including alkyl ether sulfates and ethoxylated thiols. <P>SOLUTION: The ink composition comprises suitable carrier vehicle, which typically contains water, alcohols, surfactants, humectants and optinally a resin component. The surfactants are amphipathic subatances expressed by R-O-QAM (R is an alkyl, an aryl, an alkylaryl or an alkenyl group; Q is a repeating unit of ethylene oxide or propylene oxide with 4 or more repeating units; A is a sulfate, a sulfonate or a phosphate group; M is a cationic group such as pottasium, sodium, lithium or ammonium or the like). <P>COPYRIGHT: (C)2004,JPO&NCIPI |
