Fundamental Aspects and Recent Progress in Pigment Dispersion

Abstract

States of pigment dispersion affects the various ink properties. The degree of dispersion and the interaction between the dispersed pigment particles are dependent on the mill base formulation. Fundamental aspects to design the mill base formulations are discussed mainly from the view point of the interfacial phenomena between pigments, dispersants and solvents.

Recent progress in the pigment dispersion technology such as novel grinding mills and pigment dispersants prepared by the controlled polymerization methods are briefly introduced.
