ABSTRACT:
The specification discloses a method for treating a pigment presscake containing pigment and water to remove the water therefrom. The method is carried out by contacting the presscake with a flushing agent containing an uncatalyzed or acid catalyzed rosin ester and an ink oil to provide a mixture containing the pigment, the flushing agent and water which is then separated from the mixture by well known separation techniques such as decanting to provide a flushed pigment. The specification also discloses a flushing agent and an ink composition containing the uncatalyzed or acid catalyzed rosin ester.
