Abstract

The present invention provides processes for the production of a pigment composition comprising: Ia) contacting a pigment, before or during its synthesis, with a water-immiscible carrier medium, arid then completing the pigment synthesis to produce a pigment composition comprising the pigment and the water-immiscible carrier medium, and isolating the product or, optionally Ib) contacting the resulting aqueous fully-synthesized pigment composition with an aliphatic organic acid and optionally a water-immiscible carrier medium; adjusting the pH
value of the mixture so obtained to below 7.0; and then adjusting to the pH value of the mixture to a value above 7.0 thereby transferring the organic acid into the aqueous phase; and isolating a pigment composition comprising the pigment and the water-immiscible carrier medium, or II) contacting an aqueous conventionally fully-synthesized pigment slurry with an aliphatic organic acid and a water-immiscible carrier medium according to above step Ib).
