ABSTRACT:
A process for the production of a colored resin composition, comprising a step (A) of producing an aqueous slurry of a pigment, a step (B) of producing a melting composition of metallocene type polyolefin containing a dispersant and a solvent, a step (C) of kneading the aqueous slurry obtained in the step (A) with the melting composition obtained in the step (B) and a step (D) of removing the solvent and the water from the kneaded mixture obtained in the step (C), a colored composition obtained in the above process has excellent in pigment dispersibility and high color developing properties, a colored resin molded article obtained from the colored resin composition do not give a physical-properties inhibition of 5% or higher and has a color developing properties.
