Ink jet ink

a technology of inkjet ink and water, which is applied in the field of aqueous inkjet ink, can solve the problems of insufficient dispersion of pigments for inkjet applications, inability to use non-aqueous ink, and inability to disperse pigments that may be “well dispersed” for other applications, etc., and achieves simple shaking, reduced settling of titanium dioxide particles, and easy re-dispersion and rejuvenation

Abstract

The present invention pertains to an aqueous inkjet ink made from certain aqueous titanium dioxide slurries, 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 use of the specific titanium dioxide slurries described herein result in inkjet inks having improved stability and better anti-settling performance with less pigment agglomeration and flocculation over time.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention pertains to an aqueous inkjet ink made from certain titanium dioxide slurries 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 use of the specific titanium dioxide slurries described herein result in inkjet inks having improved stability and better anti-settling performance with less pigment agglomeration and flocculation over time.

[0003] 2. Description of the Related Art

[0004] Inkjet printing is a non-impact printing process in which droplets of ink are deposited on print media, such as paper or polymeric substrates, to form the desired image. The droplets are ejected from a printhead in response to electrical signals generated by a microprocessor.

[0005] Colored inkjet inks comprise one or more colorants that are dissolved (e.g., dyes) and / or dispersed (e.g., pigments and dispersed dyes) in the ink...
