The dispersion of pigment agglomerates is affected by the morphology of the constituent solids, chemical interactions between the solids and the processing medium, and the presence of the suspension medium within the agglomerate. Differences in the dispersion characteristic of two prototypical pigments, carbon black and copper phthalocyanine, were contrasted in terms of these governing factors. Stability tests of the pigments in a variety of solvents point out the differences in interaction of the solids with the processing medium. Cohesivity tests performed on the solids indicate the role of particle morphology. Rates of infiltration of the suspending fluid matrix into the agglomerates depend on the packing structure of the agglomerate. Measurements of the rate of dispersion of dry and soaked agglomerates show the influence of the degree of saturation on dispersion tendencies.
