The basic requirement for stabilising the finely ground pigment particles is the adsorption of the additive molecules on the pigment surface. The additive molecules must have groups or segments that interact very strongly with the pigment surface. Possible interactions are ionic bonding, dipole-dipole forces and hydrogen bonding. Stabilisation is thought to involve several mechanisms, which will be discussed below.
