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.
Claims7
An aqueous particle-free fluid having a dynamic viscosity of less than or equal to 5 centipoise (5 mPa-sec) at 25° C., and comprising:
- (b) 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 %;
- and
- a solvo-surfactant in an amount of at least 0.1 weight % and up to and including 20 weight %,
- all amounts being based on the total weight of the aqueous particle-free fluid.
