Aqueous fluid sets for inkjet printing methods

Last updated:

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.degree. C., and each consists essentially of: a composition consisting of one or more compounds represented by the following Structure (I): HO--CH.sub.2--CH.sub.2--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. Two or more of such aqueous particle-free fluids can be packaged, sold, and use as part of fluid sets.
