IRON BLUE PIGMENT COMPOSITION AND PROCESS FOR ITS PRODUCTION Abstract of the Disclosure The production of iron blue pigment compositions by a flush- ing process has been found to be improved by carrying out the flushing step in the presence of an amine flushing agent and in- corporating into the composition during or after flusing at least one surfactant of the polyoxyethylene type.
