Pigment yellow 83 (P.Y.83) is a diarylide pigment which has been widely used in the fields of printing ink, plastics, color toner and paints, etc. P.Y.83 is a reddish yellow shade pigment with excellent light fastness, heat resistance, and solvent resistance, etc. Cold coupling reaction was introduced. Various dispersion derivatives and agents was added into starting mixture in the autoclave. After that, the mixture was grown at various solvents and temperature for the control of particle size and the improvement of dispersion property. It was found that paticale size, paticale shape and crystalline structure were controled at reaction factor such as time, temperature, various solvents. |
