Summary: | An object of the present invention is to provide a method for producing a pigment composition that can efficiently reduce the number of coarse particles in a pigment composition such as an aqueous pigment dispersion. The inventors of the present invention have achieved this object by a method of producing a pigment composition for ink, including a processing step of crushing or cracking a pigment component in a raw material composition containing the pigment component and a liquid medium using a rotor-stator processing machine 100. |
