Abstract

Disclosed is a non-aqueous inkjet ink containing certain titanium dioxide slurries, an associated inkjet ink set for inkjet printing, and a method of inkjet printing with the inkjet ink or ink set. The solvent and mixtures of solvents used for the dispersed titanium dioxide have a hydrogen bonding solubility parameter of greater than about 9. The inks have improved anti-settling properties with less pigment agglomeration and flocculation over time such that they can be utilized to prepare a stable inkjet ink. Also described is the use of this ink to print on colored or transparent surfaces.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority under 35 U.S.C. §119 from U.S. Provisional Application Ser. No. 60 / 549,607 (filed Mar. 2, 2004), the disclosure of which is incorporated by reference herein for all purposes as if fully set forth.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This present invention pertains to a non-aqueous inkjet ink made from titanium dioxide and an associated inkjet ink set for inkjet printing. The invention also pertains to a method of inkjet printing with the ink and ink set. The inks utilized herein have improved anti-settling performance with less pigment agglomeration and flocculation over time such that they can be utilized as a stable inkjet ink. The white ink based on the titanium dioxide provides new means to digitally print white ink by itself, but also with other colors.
