Abstract
Description
【Technical field】
[0001] The invention relates to the technical field of color paste, in particular to an ultra-high dispersibility red pigment color paste. 【Background technique】
[0002] The color paste for preparing gel pen ink must have high pigment dispersion stability and good compatibility with other ink additives. The color paste is required to have a fine particle size and uniform distribution, and a strong ability to resist external interference. Otherwise, once it is used in neutral ink and gel pen, the surface of the ink will be blurred, and the ink will be prone to agglomeration and stratification.
[0003] The preparation process of the color paste is mainly the process of dispersing and stabilizing the pigment particles. The dispersant forms a transition connection between the dispersion medium such as water and the pigment particles. Therefore, the key to the color paste used in neutral ink preparation is the pigment, dispersant and Optimized integration of ...
