The diarylide pigmet yellow 83 (P.Y. 83), which is bright reddish yellow color and its superior lightfastness and solvent resistance, so consequently it is suited to a wider range of applications. In this study, P.Y. 83 sample was synthesized at various reaction conditions by applying the coupling reation used dispersion derivatives as dispersion agant. Changes in illite particle size, crystal size, color, and dispersion characteristics were investigated. it was found that dispersion characteristics were enhanced and color were selective controled by the introduction of dispersion derivatives. |
