    摘要: A method for preparing a pigment composition for a plastics colorant is disclosed. The pigment composition is prepared by mixing a press cake of the pigment with a liquid containing a selected type of dispersant before the resulting slurry is dried. Thus prepared pigment composition has improved dispersibility in a thermoplastic or thermoset resin and greatly reduces the filter pressure rise in the molding systems for preparing masterbatches or various plastic compositions for molding, fiber, film and sheet.
