Optimised synthesis technology for organic pigments

In the process of pigment synthesis, the addition of additives to the pigment surface treatment and modification, can make the pigment particle properties change or show better application performance. In the production process of azo pigments, the use of hybrid coupling technology not only improves the performance of the product (transparency, coloring force, fluidity, etc.), but also meets the special requirements of the user for the product (color light, etc.). Improve the production methods of known structure organic pigments, improve the application performance of organic pigments, and also choose low-cost raw materials to obtain high-yield, high-quality products. Such as water or inorganic acid instead of organic solvents to synthesize ketones, can reduce production costs, but also improve the quality of products.
