This paper summarizes the rules for selection of wetting and dispersing additives for organic and carbon black pigments, and introduces the classification of wetting and dispersing additives. In particular, the novel additives such as the high molecular weight polymeric additives synthesized via Controlled Polymerization Technology (CPT) for the dispersion of the above-mentioned pigments are introduced. Additionally, the pigment dispersing synergist additives which are exclusively used for the dispersion of the organic and carbon black pigments are explained. After the dispersion of pigments is finished, it is required to judge the quality of the dispersion. The commonly used evaluation methods for this purpose are briefed, including the evaluation of the pigment dispersions and the appearance of the final films.
