INKJET INK

摘要

An inkjet ink includes a pigment incorporated in an aqueous ink vehicle. The pigment includes metal oxide and/or mixed metal oxide particles and a plurality of reacted dispersant molecules attached to the outer surfaces of the particles to form a coating on the outer surfaces. The reacted dispersant molecules are attached to the metal oxide and/or mixed metal oxide particle outer surfaces through a silanol linking group of the reacted dispersant molecules. The coating is present in an amount ranging from about 10 wt % to about 50 wt % with respect to the wt % of the metal oxide and/or mixed metal oxide particles.
