Abstract
An organic pigment dispersion in a non-aqueous medium is prepared directly from an aqueous slurry containing 0.1- 20 wt% of pigment by mixing the aqueous slurry with the non-aqueous medium, with energetic agitation, and then separating the organic pigment dispersion from the residual aqueous phase. A large part of the water in the resulting pigment dispersion can be removed by making the organic pigment dispersion in the non-aqueous medium pass over a series of surfaces whose surface material has a different affinity for water on the one hand and for the non- aqueous medium on the other hand, after which the water and the pigment dispersion in the non-aqueous medium are removed from the respective surfaces. <IMAGE>
