ABSTRACT:
The production of iron blue pigment compositions by a flushing process has been found to be improved by carrying out the flushing step in the presence of an amine flushing agent and incorporating into the composition during or after flushing at least one surfactant of the polyoxyethylene type. The resulting iron blue compositions have improved consistency and dispersibility in printing inks, paints and the like.
