Abstract
Substrates can be inkjet printed using an aqueous inkjet ink composition having a dynamic viscosity of 5 centipoise (5 mPa-sec) or less at 25° C., and consisting essentially of: (a) a polymer-dispersed pigment colorant at 0.9-6 weight %; (b) a composition consisting of one or more compounds represented by the following Structure (I):HO—CH—CH—R  (I)wherein R is a substituted or unsubstituted phenyl group or a substituted or unsubstituted phenoxy group, at 0.5-2 weight %; and (c) a water-soluble humectant, co-solvents, or both, at 20 weight %. Each polymer-dispersed pigment colorant has a 50percentile particle diameter of less than 70 nm and a 95percentile particle diameter of less than 150 nm, measured using a dynamic light scattering particle size analyzer. Replenishment or maintenance fluids containing a Structure (I) compound can also be used during the inkjet printing process.
