PIGMENT COMPOSITIONS

A process for producing a pigment or dyestuff composition in the form of dustless readily-dispersible granules which comprises contactin, with agitation, an aqueous dispersion of a pigment, and an amine compound which is liquid at temperatures below 100.degree.C, insoluble in water at pH values belo...

Summary:A process for producing a pigment or dyestuff composition in the form of dustless readily-dispersible granules which comprises contactin, with agitation, an aqueous dispersion of a pigment, and an amine compound which is liquid at temperatures below 100.degree.C, insoluble in water at pH values below 7, and soluble in water at pH values above 7. the pH value being above 7, maintaining the temperature above the melting point of the amine compound, and reducing the pH to below 7 to render the amine compound soluble in water, and recovering the resulting granules.
