The present article explores the usage of functionalized urethane of robust affinity to pigment
through the reaction of polyurethane adduct with different types of polyether in order to
improve the pigment dispersion stability, color and wetting properties. The raw materials and
prepared dispersants were characterized by FTIR, GPC, Non-volatile content. The properties
and dispersing ability of the dispersants were also investigated by measuring ink viscosity,
Rheology, surface tension and particle size. The prepared polymeric dispersants were …
