INKJET INKS HAVING ANTI-ABRASION POLYMERS AND ANTI-ABRASION AIDS
First Claim
1. An aqueous inkjet ink comprising water, a charge stabilized anti-abrasion polymer provided as a hydrophobic colloidal sol, a water-soluble humectant, and a polyethyleneglycol-diether compound of Formula I as an anti-abrasion aid:
-
R1—

Abstract
An aqueous inkjet ink is described comprising water, a charge stabilized anti-abrasion polymer provided as a hydrophobic colloidal sol, a water-soluble humectant and a polyethyleneglycol-diether compound of Formula I as an anti-abrasion aid:
R1—(OCH2CH2)nO—R2 (I)
where R1 and R2 can be the same or different and are individually alkyl with 1 to 4 carbons, or phenyl, and n is between 2 and 45. Also described is a related aqueous inkjet ink-set and an image forming method having the step of imagewise applying by jetting to a receiver, one or more aqueous inks, as above described.
