This document discusses the functions of dispersing additives in ink. It begins by explaining what pigments are and how their properties like particle size affect application characteristics. It then discusses the objective of pigment dispersion, which is to separate pigment agglomerates formed during drying. Dispersing additives improve dispersion by reducing inter-particle attraction and creating a more stable dispersion. The document covers different types of dispersing additives like polymers, surfactants, and their mechanisms of stabilization like steric and electrostatic stabilization. It provides details on how dispersing additives adsorb and anchor to pigment surfaces. In summary, the key points are that dispersing additives improve properties like gloss and color strength by creating a
