To prepare diarylide compound pigment with high shield and bright yellow color, it was investigated that the property of sample should be affected by factors of pH, coupler solution temperature, kind and addition amount of dispersion precursor, and crystallization temperature in the process of coupling synthesis. The properties of sample were measured by the means of FT-IR, UV-Vis spectroscopy, PSA, zeta potential, and turbiscan. It was found that highly dispersive sample could be prepared by introduction of dispersive precursor. |
