In this work, a novel dispersant was prepared using the dichlorotriazine azo moiety (DCT) of 1-amino-4-[3-(4,6-dichlorotriazin-2-ylamino)-4-sulfophenylamino] anthraquinone-2-sulfonic acid (C. I. Reactive Blue 4) and Dodecan-1-ol (DDL) via a nucleophilic substitution reaction. The prepared dispersant was characterized by FTIR and H-1-NMR. The properties and dispersing ability of the novel dispersant was further investigated. The prepared dispersant was employed as novel dispersants for pigment dispersion in solvent-based printing ink application. The mechanical and optical properties of prepared dispersion were studied. The novel dispersant showed good optical and mechanical properties and possessed excellent dispersing ability for C.I. Pigment Blue 15:3, with good centrifuge and storage stability.
