Abstract
Aqueous particle-free fluids can be used in inkjet printing methods including continuous inkjet printing processes. Each of these fluids has a dynamic viscosity of less than or equal to 5 centipoise (5 mPa-sec) at 25° C., and each consists essentially of: a composition consisting of one or more compounds represented by the following Structure (I):
HO—CH2—CH2—R (I)
wherein R is a substituted or unsubstituted phenyl group or a substituted or unsubstituted phenoxy group, in a total amount of at least 0.5 weight % and up to and including 2 weight %, based on the total weight of the aqueous inkjet ink composition. Such aqueous particle-free fluids can be used as replenishment or printhead maintenance fluids.
