A forced ultrathin film rotary reaction method is used to maintain a minute space of 1 mm or less between two processing surfaces capable of approaching to and separating from each other and being rotating relative to each other, and the minute space is maintained between the two processing surfaces to serve as a flow path of a fluid to be processed thereby forming a forced thin film of the processed fluid and separating the pigment material in the forced thin film.
