Abstract
Inkjet ink for forming an image on a substrate includes a pigment P, a first block copolymer dispersant D1 for dispersing the pigment P and a second block copolymer dispersant D2 for dispersing the pigment P, and an aqueous carrier. The first block copolymer dispersant D1 is different from the second block copolymer dispersant D2. Each block copolymer dispersant D1, D2 includes an anchoring segment A1, A2 for anchoring to the pigment P. Each of the block copolymer dispersants D1, D2 additionally includes a matrix stabilization segment M for aqueous phase stabilization of the pigment P. The anchoring segment A1 of the first block copolymer dispersant D1 includes a repeating unit R1 and the anchoring segment A2 of the second block copolymer dispersant D2 includes a repeating unit R2, where the repeating unit R1 is less hydrophobic than the repeating unit R2.
